which oil , what viscosity



which oil , what viscosity

Postby grumpyvette » March 3rd, 2009, 9:14 am

now the short answer is that almost any name brand of automotive 10w30 oil can be used in most modern auto engines,but obviously some are going to be better quality than others,THINNER VISCOSITY'S WILL TEND TO FLOW FASTER , ESPECIALLY AT LOWER TEMPS.
ID strongly suggest you read thru the thread carefully and take a few notes. most of the more modern oil formulas designed for modern engines with roller cams and catalytic converters have a good deal less ZINC and friction reducers that the older formulations designed for the pre- catalytic converter/ emission testing, and flat tappet cam engines of the muscle car era so they have slightly less ability to lubricate the flat tappet cam lifter lobe and sliding friction, contact area, ZINC, and several other friction modifier additives were used in the older formulas as it provided extra wear resistance, but over time it tends to reduce the catalytic converter efficiency.All current engine oils have an additive called ZDDP (Zinc DialkylDithioPhosphate) for wear protection. but be aware its not the only or necessarily the most effective wear additive in all applications. In general, heavy duty engine oils (truck oils like Mobil Delvac) have a higher level of ZDDP. Automotive engine oils generally have a lower level of ZDDP to protect catalytic systems.
as the newer engines were built during the later 1980s- and 1990s that still had flat tappet cams ,the manufacturers became aware of the gradual shift in oil formulas, mostly done to allow the catalytic converters to survive, as ZDDP additives gradually burn off and are reduced over time, and the resulting ash build-up in the converters internal surface does not help catalytic converter function. and the resulting shift in durability it was causing, to flat tappet lifter valve trains and they made changes to the metallurgy of the cams ,and lifters to try to offset the wear issues , some components and applications were much more successful at the attempted improvements than others.
and the frequency of oil changes and filter changes and the way you drive also has an effect, simply waiting until oil temps reach about 200f or more before stressing an engine tends to reduce wear.
a MINIMUM level of ZDDP of 1800PPM is suggested for use with flat tappet cams and lifters AS IS breaking the cam in with a MOLY based assembly lube and an oil having that minimum ZDDP level.
both synthetic or mineral base oils will work fine, synthetics tend to last longer and have a higher tolerance for heat, theres sub links in the thread pointing out the better oils, a quality filter, reasonably frequent oil changes and a bit of research into what actually are the better oils and what you should ask for rather than asking whats on sale helps a great deal
synthetic oils generally have a higher temp limitation and can last longer between oil changes, most conventional mineral base oils work best if used at under 240F and usually are designed to operate in the 190F-230F range, but SOME modern formulations were not formulated for the older flat tappet cam and lifter friction levels. , as a general rule youll want to use the viscosity that maintains 15-20 psi at idle, once the cars engine is up to full operational temps, keep in mind. higher heat thins oil so its common to have oil pressures read higher with cold oil. and have oil pressure gradually get lower as the oil thins with increased heat.
Some modern SYNTHETIC oils can safely operate up to 280F for brief periods and will provide better engine wear protection in the 230f-270f range
theres a great deal of detailed info later in this thread
, and the answer to what oil is (BEST) is never as simple as sticking to a single brand, most oil companys produce a wide variation of grades and types, so you need to both do some quick research AND remember what to ask for specifically

its the constant supply of oil, under pressure and its constant absorbing and transfer of heat from those moving parts, and the oils ability to prevent direct physical contact of those components that's critical.
youll generally want to select an oil with a viscosity that will maintain a 15psi-20psi reading on your oil gauge, when the engines at idle speed and up to operational temperatures of about 200F, on a newer engine with tight bearing clearances that should be about a 10w30 viscosity
you can try too debate the rate moisture in oil dissipates if you choose , but I,m just pointing out that testing by several oil companys and G.M. have stated in the past that PHYSICS REQUIRES the oil temp reach and stay at or above 215F for several minutes to FORCE the trapped moisture to convert the acidic molecules to be converted back to oil and steam,and force the calcium in the oil to absorb the acidic content of the trapped exhaust gasses.
keep in mind that does NOT MEAN the oil in the sump must reach 215F it means the CIRCULATING OIL FLOW must cycle the oil continuously, long enough so that ALL the oil volume at some point cycles repeatedly over components that will raise its temp to above 215F, (not the same thing as raising all the oil in the sump,too and keeping it over 215F)
keep in mind the rings,valve springs, rockers and pistons normally run significantly hotter than other components, so a constant circulation of the oil flow is critical to the process.
a standard SBC or BBC flows between 2-6 gallons or oil thru the bearings and lifters per minute oil is obviously cooler in the sump than when draining over valve springs or trapped on piston to bore surfaces, so SO TOTAL RUNNING TIME and the percentage of the oil being heated obviously will effect the burn-off and cleaning process efficiency. you just as obviously need to be able to JUDGE when the engines run long enough and you only have a oil temp gauge to use,as a guide, so if the oil temp gauge reaches and stays near 200F or above for about 10 minutes you can be fairly sure most of the oil at some point has cycled at above 215F , if it reaches 215F on average in the sump,you can be certain that all the oil has at some point exceeded that temp.
if you just change the oil and filter about every 4500-5000 miles or so, most of the better name brand oils will work, but there are big differences in the oil that's available, example most synthetic oils tend to have a higher resistance to breaking down due to heat.
while some mineral oils start to slowly break down at about 250-260F, most synthetics can add an easy 30F to those numbers, before heat becomes a huge factor in lubrication.
ON FACT many guys ignore is that you can increase the gauge pressure reading with thicker viscosity oil, and you can decrease the gauge pressure reading with thinner viscosity oil,mods that increase the oil flow rates like drilling the front oil passage plug or grooving the lifter bores or distributor lower band will reduce the gauge pressure reading,and the resistance the pump places on the cam gear driving it.
now if you've got a flat tappet cam engine you'll want about a minimum of a .12 %-.14% zinc listed in the formula as a wear additive (LOOK THRU THE LINKS) , but 1800 ppm is the minimum ID consider with a flat tappet cam design as thats been proven to work, as a protective wear level and having some moly in the oil wont hurt at all.
I generally use, Kendal gt, Valvoline, mobile one, shell , or Texaco, in a 10w30-10w40 viscosity and have a qt of marvel mystery oil added into the mix and pureolator or wix oil filters,
once your get your engine up to operating temp. (usually about 180F-200F the oil viscosity due to the temp. and engine clearances , will quickly let you know if the viscosity is about correct, thinner oils are far easier to push thru clearances, so they get too and lube parts far faster on cold mornings but as heat increases they tend to thin out, so a good way to gauge is to look at your oil pressure gauge once the engines up to temp at idle, you'll generally want 15-20 psi at idle (no less than 10-12 psi) and a steady increase in pressure as the rpms increase up to about 65-70 psi where the oil pump bye-pass circuit limits further increases, higher oil pressure requires the oil pump to work harder, eating up potential hp, and generally provides no more increased lubrication benefits, but pressures up to about 120 psi won,t hurt the engine,
keep in mind that having a large baffled oil pan with a windage screen sure helps as it maintains oil supply to the oil pump far more consistently.
adding a few magnets to trap metallic dust sure won,t hurt either
with the engine up to operational temp.of between about 180f-210f
and using an oil viscosity that maintains at least 15-20 psi at hot idle in traffic,
your engine should maintain a MINIMUM of 10 psi per 1000rpm and max out pressure at about 4500-5500rpm at 60psi or higher
remember the thicker the oil the harder it is to force thru the clearances in the engine, and pressure is how you measure the RESISTANCE to oil flow, but you should use an oil viscosity that at least maintains that 15-20 psi at idle

whats your oil pressure at idle?
oil pressure is the result of the balance of oil flow volume and engine clearances or the resistance to oil flow, larger clearances result in lower pressures or they can also be increased slightly with a higher viscosity oil that's a bit more difficult to force thru tight clearances.
if its under about 20 psi, at idle with the engine up to temp, it may not be enough to fully seat the lifters push rod seats up to the full extent,, your clearances may be large enough that you can use a high volume oil pump, and it sure won,t hurt to loosen up the lifter seats, why not do an oil change and add a quart of marvel mystery oil so the solvents can brake loose any crud and swap to a higher viscosity, IE, if you use 10w30 now swap to 20w50,viscosity just to see if it clears up the noise issue, if it does then you know its basically an oil flow/volume issue and swapping to a high volume oil pump will mask the problem, by supplying more low rpm oil flow/volume with your standard mix of oil, but you may also want to mix in a couple quarts of 10w30 and 20w50 as the oil/viscosity will better suit your clearances

http://www.elephantracing.com/techtopic ... rature.htm

as a general rule as your engine oil viscosity is reduced the effort required to pump the oil thru clearances is lower and the pressure reading on the gauge drops, thats not necessarily an indication of lower bearing protection, as thats generally a function of oil quality and its formula, and basic components used, in its design, and generally its increased flow rate increases bearing cooling, a good quality 10w30 should ideally provide 20-22 psi at 800rpm idle (anything over 15-17 psi at 800rpm is fine) and 60-65psi by 5000rpm which is all you can use

BTW one frequently overlooked factor, in cooling your engine or adding an additional oil cooler, is your alternator size,in amps and wiring the alternator correctly, if your running a 70amp-100 amp stock alternator and using electric fans to cool the engine,its not going to provide the power required to spin the fans nearly fast enough to cool the engine like a better 200 amp alternator can

This is the real story behind the myths. With ever increasing limits on emissions, automobile manufacturers have tightened emission control systems on newer vehicles. This is one of several factors considered when the American Petroleum Institute (API) sets standards for engine oil. The current API standard is SM which replaced the previous SL classification. Because phosphorus can poison a vehicles emission system, the level of zinc is lower for current engine oil. Because of this, many hands-on car enthusiasts and engine experts believe the lower levels of zinc in SM engine oil is causing excessive wear in older style push-rod and flat tappet engines. This is despite the fact that all new engine oil classifications are intended to be backward compatible, which in turn has resulted in the widely accepted belief that modern engine oil is not adequate to protect older engines.Valvoline uses an advanced zinc/phosphorus additive that keeps higher levels of phosphorus in the engine oil where it protects the engine, instead of poisoning the catalytic converter. Valvoline is the only brand offering this unique additive across its entire line of passenger car engine oils, including SynPower which is the only synthetic offering this additive.The only exclusion to this would be if you are operating a high performance or aggressive cam application, where high Zinc levels may be required. Because of these requirements, there are high-zinc engine oils available to meet this need, such as our Valvoline VR1 Racing Oil. The VR1 Racing Oil establishes a 75% higher zinc content than SM engine oil with a balanced additive package designed to work in both racing and street-legal applications. This product will protect older style push-rod and flat tappet engines and carries an oil change interval recommendation of 3 month/3,000 miles.It is important to note, however, that the entire additive package still needs to be balanced for best performance. For example, engine oil with a high zinc level but low detergent may not perform over a drain interval of 3,000 miles or longer.

keep in mind that your oil pressure gauge measures the resistance to flow the oil sees as it flows thru the bearing clearances, larger clearances will require higher flow rates or a higher viscosity oil, higher flow rates can be supplied with a high volume oil pump but that also requires a larger baffled oil pan and windage screen to control the higher oil flow rates

with the engine up to operating temperature (about 180F-210f oil temp) you should be fine, but even cold it should flow and lubricate reasonably well if youve got at least 15-20 psi at idle and a minimum of about 10 psi additional per thousand rpm up to about 6000 rpm, roller cams require less oil flow and it generally takes under 5 minutes at idle for engine oil to hit 170F or above


keep in mind oil accumulates soot and acids over time, and even the fine black soot , most filters won,t strain out causes wear, so oil needs to be changed, even if its well filtered

Re: which oil , what viscosity (Lynn63 posted this)

Postby grumpyvette » April 20th, 2010, 10:35 am

I, too, used to question "0" weight oils thinking they didn't have any viscosity. A few years ago I ran across a book titled "Motor Oils and Engine Lubrication" by Dave Mann, a lubrication engineer and member of the Society of Automotive Engineers (SAE). Here is an excerpt from his book.

"AMSOIL 0W-30 5W-30 and 10W-30 synthetic motor oils are ALL 30 weight oils. The answer is that ANY one can be used regardless if your vehicle owners manual says to use, for example, a 5W-30. "W" means winter. In winter weather the 0W oil will flow like a 0W oil, and the 5W will flow like a 5W oil and a 10W will flow like a 10W oil just until the engine warms up. In order to understand the differences you must first understand that the numerical values given to these various weight oils are strictly empirical numbers. For example, 0W does not mean that the oil has no weight. It is simply an assigned number to compare with another assigned number such as 0W compared with 10W. That is one of the reasons why we say it is strictly an empirical number.

In order to determine the differences between the three oils you have to look at the kinematic viscosity of each lubricant. The kinematic viscosity is essentially the amount of time, in centistokes, that it takes for a specified volume of the lubricant to flow through a fixed diameter orifice at a given temperature.

Let's compare the kinematic viscosity of the three AMSOIL lubricants:

* AMSOIL 0W-30 is 57.3 cST @ 40 deg. C, & 11.3 cST @ 100 deg. C
* AMSOIL 5W-30 is 59.5 cST @ 40 deg. C, & 11.7 cST @ 100 deg. C
* AMSOIL 10W-30 is 66.1 cST @ 40 deg. C, & 11.7 cST @ 100 deg. C

Here is the important part.
As you can see from the data above the kinematic viscosities are extremely close. Therefore, whether you use the 0W-30 5W-30 or the 10W-30 is strictly a matter of choice. With the small differences in kinematic viscosity you would be hard-pressed to detect these differences on initial engine start-up without specialized engine test equipment.

All three oils are excellent motor oils and ANY one can be used in a vehicle which requires either a 0W-30 5W-30 or 10W-30 oil as well as in several other engine applications including an engine which recommends a 5W- 20 oil."

I have been using 0W30 in my 99 Venture van for over three years now without any problems.

I hope this helps a little.

I frequently hear the younger guys say that they want to run a 160F t-stat because they hear that cooler air is denser and holds a higher oxygen content, and while thats true the fuel air mix in an intake port can very easily be traveling 100-300 feet per minute, that means that in a typical intake manifold at lets assume a low cruise speed the time it takes an individual cubic inch of air to be blended with fuel mist and too move from the carburetor or throttle body to combustion chamber could easily be less than 1/20 of a second, how much heat transfer do you thinks accomplished in that time span?

oil must reach and at least briefly exceed 215F to burn off moisture and prevent acids from forming, bearing surface temps can and do run 50-70 degrees hotter than oil in the oil pan, so if the engine oil circulates for at least 15-20 minutes this is seldom an issue, the ideal oil temp range in the oil pan,would normally fall in the 180F-210F range as this both lubricates, cleans and COOLs the bearing surfaces.
oil needs to be changed on a regular basis, you don,t need to change it as frequently as in years past (every 3500 miles) but every 5000,too 8000miles is mandatory if your to maintain top performance from lubricant oil

when selecting oil,for your engine, thinner viscosity oils pump with less effort and transfer heat away from bearings and the valve train faster so within reasonable limits thinner oil provides better protection, but you MUST maintain adequate film strength naturally, keep in mind the gauge pressure indicates is mostly the result of RESISTANCE TO FLOW thru the engine bearing clearances
you don,t really care what it is cold but once its up to operational temperatures of about 200F -210F oil temp it should ideally be thick enough (HIGH ENOUGH VISCOSITY) to maintain about 15-20 PSI at idle and gain about 10 psi per 1000rpm up to about 60-65 psi, theres nothing gained if the pressures higher it just puts additional strain on the oil pump and cam gears

most engine wear occurs during the first 7-10 minutes while the engines oil and coolant are getting up to operational temps and the parts stabilize, it usually takes 7-10 minutes of normal low speed street driving for oil to reach optimal operational temps.
oil temps normally run 10F-15F higher than coolant temps in most engines under cruise conditions but spike higher rapidly under high loads or under rapid rpm increases

oil temperatures below about 180F don,t allow the oil to flow and function correctly, and oil temps over about 230F slowly form varnishes and sludge the higher the temps the faster the oil degrades

Some experts estimate that the wear on the rings of an internal combustion engine is as high as 0.001" per 1000 miles of operation when the oil temperature is below 170 degrees F. If the maximum allowable wear is 0.006", how long can you run your engine when the oil temperature is below 170 degrees before you wear it out?"

Detailed info of High Performance and Racing Oil:

Lucas 10W30 Racing Only (lab tested 2011)
Silicon = 18 ppm (anti-foaming agent in new oil, but in used oil, certain gasket materials and dirt can also add to this number)
Boron = <5 ppm (detergent/dispersant, anti-deposit buildup/anti-sludge)
Magnesium = 1 ppm (detergent/dispersant, anti-deposit buildup/anti-sludge)
Calcium = 2929 ppm (detergent/dispersant, anti-deposit buildup/anti-sludge)
Barium = 9 ppm (detergent/dispersant, anti-deposit buildup/anti-sludge)
Total detergent/dispersant (anti-deposit buildup/anti-sludge) = 2943 ppm
Zinc = 2642 ppm (anti-wear)
Phos = 3489 ppm (anti-wear)
Moly = 1764 ppm (anti-wear)
Total anti-wear = 7895 ppm***
Potassium = <5 ppm (anti-freeze inhibitor)
Sodium = 9 ppm (anti-freeze inhibitor)
Tin = 23 ppm (from bearings, bronze parts and piston coatings, but this is brand new oil……..)
TBN = 9.0 (Total Base Number is an acid neutralizer to prevent corrosion. Most gasoline engine motor oils start with TBN around 8 or 9. And in use, this becomes depleted over time as mileage accumulates)
Viscosity (cSt at 100*C) = 11.5 (cSt range for SAE 30 is 9.3 to 12.4) And cSt (centistokes) in general terms, represents an oil’s thickness.

***NOTE: The zinc and phosphorus anti-wear levels of all oil in this list, are elemental values, which are NOT the same as ZDDP values. Earlier oil industry testing found that above .14% or 1,400 ppm, ZDDP INCREASED long term wear, even though break-in wear was reduced. And it was also found that .20% or 2,000 ppm ZDDP started attacking the grain boundaries in the iron, resulting in camshaft spalling.

But the correlation between elemental values and ZDDP values varies by motor oil manufacturer, and they do NOT publish their ZDDP values. That makes it difficult to impossible for the consumer to know how elemental and ZDDP values actually compare for any particular oil. However, these elemental values are so extremely high here, that this oil really is only suited for short life dedicated racing engines, as the name implies. Using zinc/phos levels this high in other engines could be cause for concern, since excessively high levels, used for more than just break-in, can “cause” engine damage rather than “prevent” it.

This by Brad Penn:
There is such a thing as too much ZDDP.
ZDDP is surface aggressive, and too much can be a detriment.
ZDDP fights for the surface, blocking other additive performance.
Acids generated due to excessive ZDDP contact will “tie-up” detergents thus encouraging corrosive wear.
ZDDP effectiveness plateaus, more does NOT translate into more protection. Only so much is utilized.
We don’t need to saturate our oil with ZDDP.

**NOTE: The zinc and phosphorus anti-wear levels of all oil in this list, are elemental values, which are NOT the same as ZDDP values. Earlier oil industry testing found that above .14% or 1,400 ppm, ZDDP INCREASED long term wear, even though break-in wear was reduced. And it was also found that .20% or 2,000 ppm ZDDP started attacking the grain boundaries in the iron, resulting in camshaft spalling.

But the correlation between elemental values and ZDDP values varies by motor oil manufacturer, and they do NOT publish their ZDDP values. That makes it difficult to impossible for the consumer to know how elemental and ZDDP values actually compare for any particular oil. However, these elemental values are high enough here, that this oil really is only suited for short life dedicated racing engines, as the name implies. Using zinc/phos levels this high in other engines could be cause for concern, since excessively high levels, used for more than just break-in, can “cause” engine damage rather than “prevent” it.

This by Brad Penn:
There is such a thing as too much ZDDP.
ZDDP is surface aggressive, and too much can be a detriment.
ZDDP fights for the surface, blocking other additive performance.
Acids generated due to excessive ZDDP contact will “tie-up” detergents thus encouraging corrosive wear.
ZDDP effectiveness plateaus, more does NOT translate into more protection. Only so much is utilized.
We don’t need to saturate our oil with ZDDP.
*NOTE: The low TBN value in this Redline oil is also consistent with short term use only.

Joe Gibbs 10W30 XP3 Racing Oil (lab tested 2011)
NOTE: Some of the numbers here were so unusual and unexpected, that I had the lab re-test the oil sample on another day, after other oil tests showed normal results, just to ensure that the original test was valid. And the re –test came back with the exact same numbers. So, the numbers here, are what they are. But we know this line of oil works incredibly well. Because it was developed for, and is used by, winning Sprint Cup NASCAR teams.

The detergent and TBN levels are so very low here, that this oil should most likely be changed after every outing, before those components are totally exhausted.

This oil line is one of the leading oils used in NASCAR Sprint Cup endurance engines, yet it has very low levels of zinc/phos, about the same as modern API SN oils. So, this is one example of a textbook case showing that you cannot really depend on elemental zinc/phos numbers alone, to predict how well an oil can protect against wear in high HP, high RPM engines. If you looked at the zinc/phos levels alone, like so many folks do, you’d think this oil should only be used in granny’s late model grocery getter.

This is something that the Royal Purple folks have said all along as well. Because their proprietary “Synerlec” additive is their primary extreme pressure additive, and their zinc/phos levels are only icing on the cake and do not need to be as high as it does with other oils.

The only way to really know how oils compare to each other with regard to preventing metal to metal contact, is to perform lab testing (quickest and most controlled method, particularly when testing a large number of oils) or real world on the road or on the track testing (time consuming, not well controlled, and perhaps impractical if a lot of oils are involved). This way you can test the whole additive package along with its base oil, to see how the overall product actually works. Simply looking at an oil lab test printout, is not enough information to always give you the right answer.

It’s the same thing with a new engine. You don’t just look at its build sheet to really see how well it will perform. You test it on the dyno and/or on the track (or road), to see the real deal.

So, with all that in mind, I’ve ordered an oil wear tester. And in the coming months, I’ll be performing impartial testing of all the oils on this list, and maybe a few others, to see how they rank against each other. I don’t really care which one wins or how they rank. I just want to “KNOW” which one wins and how they rank, so that I can make a better informed decision as to which oil I want to run in my own motors. I have no problem switching brands if the test results show the need to do so. Once I put all that data together, I’ll post the results for anyone interested in seeing it.

The detergent, anti-wear and TBN components of this Extended Performance oil are either about average or below average for typical API SN oils (even though some of the components are a little higher than in its standard Mobil 1 counterpart). TBN eventually becomes depleted as miles accumulate on oil in service. That’s “one” of the primary reasons for changing oil in the first place, to replenish the exhausted additive package. And it’s not unusual to see TBN values drop by as much as 60% from the original value, in only 5,000 miles. And with this oil starting out with a fairly low TBN value to begin with, it would seem very unlikely it could ever go a whopping 15,000 miles without having the TBN totally depleted well before reaching that 15,000 mile mark. So, this extended mileage claim appears to be only an unsupported marketing gimmick.

But, for those interested in long drain intervals, I’d suggest sending in a sample of this oil and having it lab tested at about the half way mark of 7,500 miles to see how much, if any, TBN remains. But, of course motor oil is typically already dark, dirty, contaminated and in need of changing by 5,000 miles anyway.

Re: which oil , what viscosity

http://www.animegame.com/cars/Oil%20Tests.pdf

read thru this link above it should make you see there really is a huge difference in the protection some oils provide and its rather surprising that those oils might not be the ones many of us use.
I know IM going to be changing what Ive used for years (mobile one) as the formula for that oil changed recently (not for the better) and the price tripled over the last couple years



from a different test
Motor Oil Wear Test Results and Ranking

*** The higher the psi result, the higher the “Load carrying capacity/Film strength”, and the better the oil is at preventing wear.

*** All oils were tested at 230* F (representative of actual running temperature).

*** Multiple tests were performed on each oil, and those results were averaged to arrive at each oil’s final value shown below. Differences between oils of 10% or less, are not significant, and oils within that range can be considered approximately equivalent.

*** All oil bottles were thoroughly shaken before the samples were taken. This ensured that all the additive package components were distributed uniformly throughout all the oil in the bottle, and not settled to the bottom.

*** All oils are full synthetic unless otherwise specified.

*** All oils are suitable for street use unless otherwise specified.


Oil categories:

*** Over 90,000 psi = OUTSTANDING protection

*** 75,000 to 90,000 psi = GOOD protection

*** 60,000 to 75,000 psi = MODEST protection

*** Below 60,000 psi = UNACCEPTABLE protection

Summary:

Readers can of course do whatever they want with these results. But for me, seeing is believing. The smallest wear scars created by the best oils, were quite impressive. So, now I’ll be choosing oils for my Hotrods and daily drivers from the OUTSTANDING PROTECTION category, in order to have the highest level of protection. There are plenty of different oils in this category, 28 of the 44 to be exact, and they all have 90,000 psi or higher capability. After reading this report, you may never think about motor oil the same way again.

Re: which oil , what viscosity

NASCAR Racing Oil Test Results
Of course I've always known that my carefully generated “motor oil wear protection capability data” was completely accurate, but now my data has been validated and backed-up by a total of FOUR other independent Industry sources. They are as follows:

1. Well known and respected Engineer and Tech Author David Vizard, whose own test data, largely based on real world engine dyno testing, has concluded that more zinc in motor oil can be damaging, more zinc does NOT provide today's best wear protection, and that using zinc as the primary anti-wear component, is outdated technology.

2. The GM Oil Report titled, "Oil Myths from GM Techlink", concluded that high levels of zinc are damaging and that more zinc does NOT provide more wear protection.

3. A motor oil research article written by Ed Hackett titled, "More than you ever wanted to know about Motor Oil", concluded that more zinc does NOT provide more wear protection, it only provides longer wear protection.

4. This from the Brad Penn Oil Company:
There is such a thing as too much ZDDP. ZDDP is surface aggressive, and too much can be a detriment. ZDDP fights for the surface, blocking other additive performance. Acids generated due to excessive ZDDP contact will “tie-up” detergents thus encouraging corrosive wear. ZDDP effectiveness plateaus, more does NOT translate into more protection. Only so much is utilized. We don’t need to saturate our oil with ZDDP.

Those who are familiar with my test data, know that my test results came up with the exact same results stated by all four of those independent sources. So, this is an example where motor oil “Dynamic Wear Testing Under Load” using oil testing equipment, engine dyno testing, Motor Oil Industry testing, and proper motor oil research using only the facts, from a total of five (including my own) independent sources, all converged to agree and come to the same exact conclusion. Back-up validation proof, doesn't get any better than this.

So, with all those sources in total agreement, that should provide more than enough proof to anyone who questioned my test data, that my data is absolutely correct. And that questioning any one of those sources, questions them all, and questions Physics and Chemistry that determined all those identical results. And no sensible person would try to argue against Physics and Chemistry. Because that is a battle no man can win.


**************************

Now, getting to the purpose of this write-up, a NASCAR engine supplier out of North Carolina, was so impressed with the motor oil “Wear Protection Capability Testing” I perform, that they sent me 3 NASCAR Racing Oils they use, for testing. I considered that quite an endorsement, that these guys valued my testing efforts enough to include me, in some of what they do. They have been seeing some wear issues, and wanted to see if I could shed any light on that by testing their oil. They came to the right place.

The NASCAR oils they sent me were:

0W Mobil 1 Racing Oil (this was out of a 55 gallon drum)

0W30 Mobil 1 Racing Oil (this was out of a normal quart bottle)

0W50 Mobil 1 Racing Oil (this was out of a 55 gallon drum)

In addition to performing my normal “Dynamic Wear Testing Under Load”, I also sent all 3 oils to the Professional Lab, ALS Tribology in Sparks, Nevada for them to perform component quantity and viscosity testing. The test results from the lab are:

*****************************


After I performed my “Dynamic Wear Testing Under Load”, you can see below how those 3 NASCAR oils ranked regarding “Wear Protection Capability”, just among other Mobil 1 oils I’ve tested, as well as among other oils I’ve tested that had “Racing Oil” in their name. And they are all ranked in the order of their “Wear Protection Capability” values.

Wear protection reference categories are:

Over 90,000 psi = OUTSTANDING wear protection

• 75,000 to 90,000 psi = GOOD wear protection

• 60,000 to 75,000 psi = MODEST wear protection

• Below 60,000 psi = UNDESIRABLE wear prot
ection

The HIGHER the psi value, the BETTER the Wear Protection.

Onset of thermal breakdown = 210*F, which was confirmed by repeated tests. This is the WORST/LOWEST onset of thermal breakdown point I’ve ever seen. So, this oil is STARTING TO FAIL even before getting hot enough to quickly boil off normal water condensation. And this is on top of its very poor wear protection capability. Mobil should be embarrassed to even offer this oil for sale.



So, as you can see, these Mobil 1 Racing Oils were poorly ranked at 15th, 16th and 23rd, out of these 23 oils above.

And if you look at my “Wear Protection Ranking List” of all 104 oils I’ve tested so far, you’ll see they rank 65th, 72nd and 99th.

The wind-up is that the 0W50 Mobil 1 Racing Oil and the 0W30 Mobil 1 Racing Oil only provide MODEST wear protection, while the 0W Mobil 1 Racing Oil only provides UNDESIRABLE wear protection. So, it is quite clear that these modest/poor performing motor oils are NOT a good choice for NASCAR small block endurance engines that make around 900HP, rev between 9,000 and 10,000 rpm, and do that for hundreds of miles. For applications like this, choosing an oil is just as important as choosing the engine components.

All 3 of these oils might look good on paper for wear protection, since the zinc, phos and moly are all substantial. However, this is yet another example of how looking at a Lab Test Print Out of an oil’s component quantities, shows you absolutely nothing regarding how well it can protect against wear. The ONLY way to determine the FACTS as to how well an oil can protect against wear, is to perform “Dynamic Wear Testing Under Load”, which is precisely why I test oil that way.

You don’t just rely on an engine’s build sheet to guess its power/torque characteristics. You dyno test it and track test it, to find out how it really performs in operation. It’s the same thing with testing motor oil. You don’t just rely on an oil’s Lab Test Print Out, you need to test it dynamically at a representative operational temperature to find out what its wear protection capabilities really are.

The wear issues this NASCAR engine supplier was experiencing with these oils, is exactly what you would expect by looking at my “Dynamic Wear Testing Under Load” test results, which showed that the oils were severely lacking in wear protection capability. Unfortunately, they had no way of knowing this before they started using these oils. But, if I had tested these oils BEFORE they started using them, I could have saved them time, money and grief.

An oil’s ability to protect against wear, is determined by its base oil and its additive package “as a whole”, NOT just by how much zinc is present. Using zinc as the primary anti-wear component, is outdated technology. The idea that you need a high level of zinc for a high level of wear protection, is simply an old MYTH that has been BUSTED. Many of today’s anti-wear components (they are often proprietary in nature, and are not specifically tested for, in a basic Lab Test) are not only equal to zinc, but they are BETTER than zinc.

Until I started performing Tribology Research, and setup my motor oil “Wear Protection Capability Ranking List”, there was no good way to know which oils provided good wear protection, and which oils didn’t. Previously, all we could do was guess, or use trial and error to determine which oil was good enough, and which oil was not. And even then, we had no way of knowing how various “good enough” oils compared among themselves. But now, we have documented wear test data available. So, all we have to do is look at the Ranking List, and choose an oil that provides the wear protection we are comfortable with for any given build. This is the 21st Century, and we no longer have to guess or use trial and error to decide on which oil to use.

Also, engines are best served by using oils that have excellent wear protection capability (no matter how much zinc is in them) during Break-In. If folks use these superior oils, and avoid traditional high zinc, low wear protection capability Break-In oils and avoid aftermarket zinc additives which actually REDUCE an oil’s wear protection capability, worries about flat tappet Break-In procedures could become a thing of the past.

The “Wear Protection” test data here DIRECTLY APPLIES to flat tappet lobe/lifter interfaces (no matter how wicked the engine), distributor gear/cam gear interfaces, mechanical fuel pump pushrod tip/cam eccentric interfaces, and all highly loaded engine interfaces.


BOTTOM LINE:
I have no doubt that this Professional NASCAR engine supplier is using good quality engine components, and that they are building their engines well, so all they need to do is select better oils, and their wear issues will go away. Fortunately, there are many, many far better oils available for them to choose from. Even 5W30 Mobil 1, API SN synthetic street oil, that is available at any Auto Parts Store, provides a whopping 47% MORE WEAR PROTECTION than the 0W30 Mobil 1 Racing Oil.

Of course, there can be friction reduction capability differences between street oil and Racing Oil. And keep in mind, that friction reduction and wear protection are two entirely different things, and often do not go hand in hand. If a particular Racing Oil does provide reduced friction, that can increase HP. But, you still have to finish, and you have to run strong to win. So, no matter what, your oil has to provide adequate wear protection to get the job done.

If I were choosing the oils for this NASCAR endurance engine application, as an Engineer, I’d only select oils from the OUTSTANDING wear protection category, which means oils that produce at least 90,000 psi capability in my testing. Any oil in that category would provide sufficient margin of safety to prevent any further wear issues.
