ZDDP additive

[Bee1971]

3. 10W30 Valvoline VR1 Conventional Racing Oil (silver bottle) = 103,505 psi
zinc = 1472 ppm
phos = 1544 ppm
ZDDP = 1500 ppm

What I have been using since building my motor this past winter

However I used Comp Cams Break In Oil to prime the engine and initial run up in the garage a few times - Going to have to rebuild it again this upcoming winter after reading that article LOL

I cut open the WIX filter and pulled out all the filter paper media after initial break in Comp Cams Oil and twice more this summer running the VR1 Racing Oil

A@P mechanics at work told me perfection on all three , I couldn’t bee happier

The thing about oil is, there is going to be a point, where the additional mineral PPM is not necessarily better and a lower amount is sufficient. The old Rotella formula had 1,200 PPM of ZDDP. That is the gold standard in longevity for mechanical, flat-tappet engines. Mobil 1 states that 1,000 PPM of ZDDP is well-enough for a flat-tappet engine, which is even found in their Mobil 1 FS - 0w40 synthetic oil (European formula).

Again, the author of the study, 540 RAT, states that his test procedure does not directly correlate to an automotive engine, specifically:

"My test equipment is NOT intended to duplicate an engine’s internal components"... "a running engine is designed to last indefinitely, and of course, they do not generally cause an oil to reach its failure point. So, due to the complete difference in design, the pressures in my test are completely different, and cannot be compared directly to an engine’s lobe/lifter interface pressure.".

Judging on terminology used, the 540 RAT test is likely based on or utilizes the The Falex Timken Extreme Pressure Test Rig - ASTM Standard Test Methods D2509 and D2782. LINK: Falex Tribology Testing and Technical Support

In my view not really ground breaking stuff and certainly not something I'd use to draw any kind of "conclusion". Really, it's only about as useful as determining what oil does well in a laboratory bench tester. Real world working engine, not so much...

The current industry accepted test procedure for determining engine wear for API SN/GF-5 licensed motor oils is - Sequence IIIG Engine Test. (ASTM D7320) LINK: https://www.swri.org/sites/default/f...-iiig-test.pdf

540 only tests one small aspect-see Speedtalk
was at Wallmart yesterday No Mobil 1 0W-40 but they did have Castrol
There are actually very few refiners of this oil- most are just repackaged with a color change
note that it is designed for flat tappet, slider, bucket BMW and Merceedes
has the best film strength of anything
they also had the 20-50 mentioned but as said above most wear is at start up which is why gm is redommending going from a 5w-20 (or 30)to a 0w
unless you have something specai like large clearances you do not need 50W- but there must be a reason for the 15w60- what is it?

 

[Bicylindrico]

Amsoil the best?
good, but the best?

I have not looked at Amsoil 0W-40 at $11 a quart plus change
https://www.hellcat.org/threads/im-planning-on-using-this-amsoil-0w40.3084/
https://www.amsoil.com/shop/by-product/motor-oil/european/synthetic-0w-40-c-esp-euro-oil/
good, but the best? Pricy and any oil that actually meets the MB and BMW spec is pretty much the same Natural Gas Based Oil
LMFAO
Here is a recent UOA with some track use.
Mobil 1 0w40 Eurospec (or other euro that meets mfg specs) is one of the best oils you can buy.
It is better than Amsoil Euro 5w40. It stays in grade better, and is more oxidation resistant.
and 5 quarts for $25 at Wally World

Based on actual oil testing yes it appears Amsoil Signature provides the highest level oil film strength/load carrying capability/shear resistance psi value.

"For reference, at the time of this writing Amsoil 5W30 Signature Series, produced 134,352 psi, and is ranked 2nd for oils “just as they come, right out of the bottle” (only Amsoil 0W20 Signature Series, was able to slightly beat it), out of 223 oils tested so far.

This is a great read if you have the time https://540ratblog.wordpress.com/2013/06/20/motor-oil-wear-test-ranking/

Really? Must be your twin from Woodstock Il. ->

Oh, For Road Runners Only, yeah I'm there. I do recall that post. Did not realize that site was also called "The Nest". No wonder Google could never find "The Nest" Or "The Birds Nest" when I googled it.

The 540 rat tests are meaningless for real world auto applications
maybe for a conveyor belt
the best oils today are not dino but natural gas based and a combination of type IV and Type V synthetics
if you think amsoil is better than Redline or the Eurospec oil I have a bridge for you
not that amsoil is not ok- just a terrible value
remember that there are very few actual refiners of these top end oils- most come from blenders, repackagers
another key is that many use a type III (think Mobil/Castrol lawsuit) carrier for the additive packages which dilutes the IV and V synthetics

The author of the Rat 540 Blog is a mechanical engineer - what is your qualifications for your assumptions?

Well for me personally, my ASSumption is a mechanical engineer is NOT a tribologists.

See also:

"Tribology is the science and engineering of interacting surfaces in relative motion. It includes the study and application of the principles of friction, lubrication and wear. Tribology is highly interdisciplinary. It draws on many academic fields, including physics, chemistry, materials science, biology and engineering. People who work in the field of tribology are referred to as tribologists."

Perhaps you need to read the extensive discussion of 540 rat on speedtalk, bob the oil guy etc
nothing wrong with rat's one arm bandit test per sey- it is just that it is irrelevant to an auto engine
btw facts not asumptioons

 

[polywideblock]

I use this, aussie and good

 

[Moparguy59]

Thanks to Algore no zinc .They quit zincing conventional oil ,Rotella no longer has enoughzinc.most stores carry valvoline off road20-50 .I prefer brad Penn but also use penncrap with zinc additive does a good job and pencils out well.u must add something guys

 

[1967coronet440]

I’ve read with flat Tappet cams you want at least 1350 ppm or zinc.

 

[Moparguy59]

Actually that's why all the newer cars have roller cams .and als a multi millionaire

 

[biomedtechguy]

Al's a multi millionaire

I thought he got rich from his commissions off of him inventing the internet...
Hey Al.

 

[Ranger16]

Thanks to Algore no zinc .They quit zincing conventional oil ,Rotella no longer has enoughzinc.

I don't think that is correct. All motor oils still have zinc in them, just reduced amounts. I think Rotella T5 still has somewhere around 1200 ppm.

One More Time

3. 10W30 Valvoline VR1 Conventional Racing Oil (silver bottle) = 103,505 psi
zinc = 1472 ppm
phos = 1544 ppm
ZDDP = 1500 ppm

[biomedtechguy]

That's what I use. Valvoline VR1
Great oil!

 

[Sweet5ltr]

Lets get down to the reality here, what percentage of actual weight is the PPM referring to? This requires a phone call to the oil manufacture and possibly a review of the SDS (Safety Data Sheet). If you purchase oil from a parts store, they will have an SDS binder on hand and should provide you a copy if requested.

I run 15w50 Mobil 1 synthetic in my low-deck, $25 / 5-quarts @ Walmart every day. HT/HS (High Temperature / High Shear), directly packaged for boosted and race applications with flat-tappet camshafts. Recently ordered some VR1 this year for my wifes 77' Power Wagon project off Amazon, $12 / 6-quarts of 10w30 (it's back up to $30 now). Should work well for her 318 LA & .444" camshaft.

Stick with the name brands (trusted like Valvoline / Amsoil / Mobil 1) and generally you can't go wrong. With newer engines, I really doubt it makes an incredible difference in longevity either way - as long as the oil meets spec.

BTW that Mobil 1 15W50 has 1300 PPM of Zinc & 1200 PPM of Phosphorous. Nearly impossible to find that in an off-the-shelf synthetic now.

 

[Joske2]

Thats what i use also, Mobil 15W50 racing in all my flat tappet engines.
In our bespoke racing engines we use for sprint(6hrs or less) Mobil 0W30 racing and for endurance(24hrs) Mobil 0W50.
Both have 1750 Phosphorus and 1850 zinc.
