I just disproved that HPL makes "better" oils regarding foam tendency.
No you didn't.

Clearly you are fact resistant, bye.
False.The facts: ASTM D892 allows up to 50 ml of foam. HPL allows 0. Just one fact that proves HPL can exceed oils that all pass the test if they're getting > 0 ml of foam.
This isn't helping your argument so why bother.False.
Its a standard of testing. It does not approve/allow or deny/decline anything.
The point I was making is that one cannot simply say "all oils that meet standard X perform the same", because even in the standard there is wiggle room, some oils perform better even though they all meet the standard.And I don't care if HPL can exceed API/ACEA/MB/VW requirements, so can all other oil companys.
Like I just showed you.
I am fortunate enough to make most of my own oils for my own use.You got me big fella. But I get your point. Better oils or different additives can allow lower amounts of additives for similar performance.
But how would you decide which oil is "better" out of 6 oils that meet an approval?
Is it impossible, or the oils are so similar it doesn't really matter?
But how does one know if it is significant? Sure it is better at foaming but is that significant or relevant? At the license, specification or approval limit is there a tangible benefit to being better?The point I was making is that one cannot simply say "all oils that meet standard X perform the same", because even in the standard there is wiggle room, some oils perform better even though they all meet the standard.
Nobody was saying that other companies can't also exceed various standards. Just that you can't judge all oils that pass the standard as equal, because the standard still has room for varying quality as I mentioned with the 0 to 50ml foaming test.
With HPL I'm confident I'm getting the best of the best, and that's what matters to me. If you're happy running Kirkland, knock yourself out, completely not the point.

A great question for Dave/HPL.But how does one know if it is significant? Sure it is better at foaming but is that significant or relevant?

I have no idea. I guess I’ve never worried about foaming, just never been on my top 20. I care about oxidation resistance and SAPS level as well as HT/HS.A great question for Dave/HPL.
Would you agree that less foam is more likely to be better than more foam? No doubt diminishing returns plays a part, but I'm very attracted to the idea of getting the best I can especially when the cost relative to total ownership is so insignificant.
I'm sure someone buying a $5000 college beater has different views and they wouldn't necessarily be wrong either, but I'm looking at this from my perspective which is buying a brand new $50,000 vehicle (and its probably $65k today) with the goal of running it until it drops.
There is no 0 to 50ml test. ASTM D892 has no limits, its a test with measured result.
And yes with such little knowledge of oil standards I can see why you buy HPL. I probably would too.
Assurance has a high price when you are ignorant.
@hemioiler
Tell me again how the biggest GTL producer has a problem with foaming please.
I'll continue to buy Shell / Pennzoil / QS.
The test is used in standards to reach an acceptable level of foam for that standard. The point is that HPL doesn't accept any foam, which to me is a higher standard/goal.

Congrats your found the basic API and ACEA requirements. Now look up manufacture specs that are more stringent.
The point was that even if 2 oils meet the same certification/spec, it doesn't mean that you can just glibbly assume they will perform equally because the specs have wiggle room.
Really? What do you look at on a UOA to gauge oxidation resistance? Or deposit control? Or ring sticking? Turbocharger deposits? Sludge formation?Yes, that's precisely what we can do. Endless UOA's tells us exactly that.
Agree, comparing one by one you wont get much(any) usable data.Really? What do you look at on a UOA to gauge oxidation resistance? Or deposit control? Or ring sticking? Turbocharger deposits? Sludge formation?
These are all things that are vitally important. And as user edhackett has explained, a spectrographic analysis isn’t even a good proxy for wear.
No, I was going by what actual tests are performed for those considerations as part of a manufacturer approval.If you have deposit problems I would think you are using the wrong oil (spec) for the application or to long OCI.
Oxidation resistance i'm not shure, TAN & TBN?
Isn't noack % oxidation resistance...?
You'd need teardowns to draw any actual conclusions about wear.Agree, comparing one by one you wont get much(any) usable data.
But look at thousands of them.
Many applications just spec the basic API approval. There have been a few threads on Toyota 0W-16 oil consumption and ring sticking, causing scoring, due to deposits. We've also seen pictures of many engines with deposits run at "reasonable" intervals on basic API and dealer oils.If you have deposit problems I would think you are using the wrong oil (spec) for the application or to long OCI.
Nope. Oxidation is tested for in some approvals but may not be adequately captured.Oxidation resistance i'm not shure, TAN & TBN?
