Test Data on Amsoil Dominator Racing Oil

A few words before getting into the oil test data. Most Forum members have understood and appreciated the oil test data I've posted over the last year and a half or so. But, there were always some who could not accept my results that showed high zinc levels were not always something that could be counted on for superior wear protection. So, there was a lot of hostility over that. And honestly, I can understand why some folks might have a problem with my data showing that. Because for the past couple of decades, the whole Hotrod and Racing Industry did nothing but promote how wonderful high zinc levels were, which may well have been true many years ago when zinc levels first began getting significantly reduced in API certified oils. Therefore, reluctance to accept a wholesale change in thinking is not surprising, even though there are much better alternatives used in low zinc API certified oils nowadays.

The folks who could not accept my data, also seemed to get the wrong idea about it. If the oil they preferred did not rank very high on my list, and they had never had a problem using it, I never said they needed to stop using it. If they had good success with what they use, that meant they were not exceeding the capability of that oil. As long as they continued to stay below that oil’s capability limit, they would never have a problem. But, if they wanted to choose a better oil, for extra wear protection insurance, all they had to do was look at my ranking list and choose a higher ranked oil. In spite of any previous skepticism regarding my testing, we should now be able to put those issues behind us, and move forward on common ground, as one group on the same page. Here's why:

I'm a total perfectionist when it comes to technical matters. I'm a working Professional Degreed Engineer, as well as a U.S. Patent holder, who deals with technical matters for a living. Those who know me personally, know that I would never jeopardize my reputation or my integrity, by posting data that would turn the Hobby/Industry on its ear, unless I was absolutely sure about the data I put out there. And for the record, I do not, and never have, used a one armed bandit tester to perform any motor oil testing. The test results I post are not my opinion, and they are not my theory. They are the actual facts that came out of the Physics and Chemistry involved in the real world testing I perform, at a representative operational temperature of 230*F. Of course I've always known my carefully generated data was completely accurate, but now my data has been validated by a total of three 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 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.

Those familiar with the test data I post, know that my testing came up with the exact same results stated by all three of those independent sources. This is an example where wear testing using an oil tester, engine dyno testing and proper motor oil research using only the facts, from four independent sources, all converged to agree and come to the same exact conclusion. Back-up validation proof, doesn't get any better than this, in the world we live in. In fact, in most cases in the Hotrod and Racing Industry, if you ask 10 people a question, you will get 10 different answers.

So, with all those sources in total agreement, that should provide more than adequate proof to anyone who questioned my test data, that the posts I make about motor oil testing, are absolutely correct. And that questioning one of them, questions them all. So hopefully, we can leave all the arguments behind, and as we go forward, engage in respectful motor oil discussions, which we all have an interest in.

Now, on with the oil data that is the subject of this posting. Synthetic 10W30 Amsoil Dominator Racing Oil, is the latest high zinc oil I've tested. Here is the Lab Test data that came back from Professional Lab, ALS Tribology in Sparks, Nevada:

Amsoil 10W30 Dominator Racing Oil synthetic (lab tested 2013)
Silicon = 3 ppm (anti-foaming agent in new oil, but in used oil, certain gasket materials and dirt can also add to this number)
Boron = 15 ppm (detergent/dispersant, anti-deposit buildup/anti-sludge)
Magnesium = 10 ppm (detergent/dispersant, anti-deposit buildup/anti-sludge)
Calcium = 1661 ppm (detergent/dispersant, anti-deposit buildup/anti-sludge)
Barium = 0 ppm (detergent/dispersant, anti-deposit buildup/anti-sludge)
Zinc = 1613 ppm (anti-wear)
Phos = 1394 ppm (anti-wear)
Moly = 0 ppm (anti-wear)
Potassium = 4 ppm (anti-freeze corrosion inhibitor)
Sodium = 0 ppm (anti-freeze corrosion inhibitor)
TBN = 6.5 (Total Base Number) This is an acid neutralizer to prevent corrosion. Most gasoline engine motor oils start with TBN around 8 or 9.
Viscosity (cSt at 100*C) = 11.6 (cSt range for SAE 30 is 9.3 to 12.4) And cSt (centistokes) in general terms, represents an oil’s thickness.

My testing showed that the onset of thermal breakdown for this oil was approximately 300*F, which tied for the highest value I've found in all the oils I've tested for the onset of thermal breakdown. The oils that had an onset of thermal breakdown value that high, have always been Amsoil products, in my testing.

My "Dynamic Wear Testing Under Load", which determines the specific wear protection limit of an oil by testing its "Load Carrying Capacity/Film Strength", found that this oil was capable of producing a very impressive 97,118 psi. This puts it in the OUTSTANDING WEAR PROTECTION category, and makes it one of the best high zinc oils I've tested. Below is how it ranked among the other high zinc (over 1100 ppm) oils I've tested.


Wear protection reference categories are:

*** 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 = UNDESIREABLE

The higher the psi number, the better the wear protection.

1. 10W30 Lucas Racing Only synthetic = 106,505 psi

zinc = 2436 ppm (up 1848 ppm)
phos = 2053 ppm (up 1356 ppm)
ZDDP = 2200 ppm
The amount of ZDDPlus added to the oil, was the exact amount the manufacturer called for on the bottle. And the resulting psi value here was 24% LOWER than this oil had BEFORE the ZDDPlus was added to it. Most major Oil Companies say to NEVER add anything to their oils, because adding anything will upset the carefully balanced additive package, and ruin the oil’s chemical composition. And that is precisely what we see here. Adding ZDDPlus SIGNIFICANTLY REDUCED this oil’s wear prevention capability. Just the opposite of what was promised. Buyer beware.

And the resulting psi value here was a whopping 36% LOWER than this oil had BEFORE the Edelbrock Zinc Additive was added to it. Adding Edelbrock Zinc Additive SIGNIFICANTLY REDUCED this oil’s wear prevention capability. Just the opposite of what was promised. Buyer beware.

38. 10W30 Comp Cams Break-In Oil conventional = 51,749 psi

phos = 1277 ppm (up 517 ppm)
ZDDP = 1400 ppm
The amount of Edelbrock Zinc Additive added to the oil, was the exact amount the manufacturer called for on the bottle. And the resulting psi value here was a “breath taking” 44% LOWER than this oil had BEFORE the Edelbrock Zinc Additive was added to it.

41. 30wt Lucas Break-In Oil conventional = 49,455 psi
zinc = 4483 ppm
phos = 3660 ppm
ZDDP = 4000 ppm

What's far more important than this 41 high zinc oil ranking list, is the entire 97 oil ranking that you can see, along with additional motor oil tech info at:

http://540ratblog.wordpress.com/

And here are some trends that you will see in that entire 97 oil ranking list:

• Synthetic oils rank between number 1 and number 96.

• Conventional oils rank between number 6 and number 97.

• Since the ranking of synthetic oils and conventional oils completely overlap, there is no clear distinction between their wear protection capabilities.

• High zinc oils rank between number 3 and number 97, which very clearly shows that simply having a high level of zinc is no guarantee of superior wear protection.

• Low zinc oils rank between number 1 and number 74.

• Since the low zinc oils and the high zinc oils completely overlap, you can see that zinc does not play the primary role in determining an oil’s wear protection capability. An oil’s wear protection capability is determined by its base oil and its additive package “as a whole”, with the primary emphasis on the additive package, which contains the extreme pressure components. And modern alternate extreme pressure components are equal to, or better than zinc.

• Diesel oils rank between number 43 and number 78. The poor performance of these Diesel oils makes it very clear that they are a poor choice for High Performance gas engines.

• Break-In oils rank between number 73 and number 97. If you are looking for wear protection during break-in, you will be disappointed with these oils. Because they are NOT formulated to prevent wear, they are formulated to allow the parts to quickly “wear in”, which is totally unnecessary. You cannot stop parts from wearing-in on their own, no matter what oil you run. And we’ve seen that for many years with factory filled synthetic Mobil 1 in countless thousands of brand new factory vehicles, that always break-in just fine. That makes break-in oils little more than snake oil. Buyer beware.

• 20 wt oils rank between number 12 and 90.

• 30 wt oils rank between number 1 and 97.

• 40 wt oils rank between number 43 and 89.

• 50 wt oils rank between number 7 and 82.

So, as you can see, oil viscosity plays no particular role in an oil’s wear protection capability. As mentioned above, an oil’s wear protection capability is determined by its base oil and its additive package “as a whole”, with the primary emphasis on the additive package, which contains the extreme pressure components.

Re: Test Data on Amsoil Dominator Racing Oil

Interesting, thanks for taking the time. So a 10w30 vs a 10w40 same package is only adjusting the oil pressure reading?

YOU KNOW YOU HAVE THE POWER..... AND IF YOU USE THAT POWER BAD THINGS ARE GOING TO HAPPEN!!

Re: Test Data on Amsoil Dominator Racing Oil

I've been using and recommending Valvoline for decades - So I'll point out with only a small amount of "I told you so" swagger that Valvoline owns three of the top five spots overall, and the top spot for a street legal oil.

Love debunking those "snake oil additives" as well. What a laugh!

Another hearty thanks! Your work is much appreciated by this forum member.

Re: Test Data on Amsoil Dominator Racing Oil

i'd love to see a test of the Mobil 1 high mileage oils to see how they compare to the regular Mobil 1- they have 5w30, 10w30, and 10w40 at WalMart for $25 for 5 quarts..

also, do you have all these results on a web page somewhere, perhaps in a searchable format? if not, i'm sure someone out there with the proper skillset would help you set that up..
