Pennzoil Platinum used to be my favorite

So does oil 1 with 50ppm moly "perform" better than oil 2 with 750ppm of moly? Is moly one that you can say more is better?

Nope, and you know this. There’s MoS2, dimer, and trimer moly additives. They all perform differently and also have different applications and additive levels required for proper performance.

MoS2 should be used in gear oils, and Dimer requires a significantly higher level than trimer to achieve it’s stated goals, in general.

Not speaking of your fan-favorite oil sump-clogging MoS2...speaking in general w/r to some oils here that show v. high moly numbers that are usually associated by many as "better" than a comparative oil with less.

I wasn’t even going there… trying to be civil today 🤣

There are known “best applications” for each type of EP or AW additive. But yes I get your point, and that’s partly why I started a thread that asked what the real purpose of moly in engine oils was- the friction reduction aspect or the dry lubricant/anti-wear aspect. That’s not even touching the multifaceted approach of Boron, either! 👍🏻

If more of X doesn't make an oil better then boutique or Premium oils like Amsoil, Redline, HPL killer add packs mean nothing then?

Has anyone been able to prove that running such oils magically causes an engine to not wear out?

Oil blending is an art and a science. The base stock plays, the additives play, the balanced package has an outcome. Vastly improving or increasing one part of something may have good effects. But the other parts still have a non trivial impact. Killer may mean a few more ppm… in other words, a few hundred more milligrams, per kilogram of product. Far from a massive increase in the big scheme of things.
 
There was a time when this mattered

Think about this. You have top tier approved oils not only meeting demanding specifications, but greatly exceeding them (20x on IIIH etc). Tear down validation, testing validation, approval validation. But because someone can't see high levels of additive xyz they're instead going to dump unknown oil into their engines for a 5k mile drain. I just fail to see any logic here.

If that's how you feel at least use the two boutique brands that are trusthworthy - Amsoil/HPL.

Yep, I was kinda confused with the whole HPL/Amsoil/RL pissing match the other day. Several of the staff properly laid it out… this board is very cyclical with its tastes, one week this brand is “best” and next week it’s a different one… but the over-arching tone is that any of the board darlings have been, and continue to be, really good oils for their applications and will usually deliver additional performance over shelf stock oils.

Whether the user wants to spend the money or has the intestinal fortitude to make the improved characteristics of the boutiques actually show in their application is always the biggest question.

But the fact remains that none of the boutiques has ever addressed the fickle wishes of this board as completely or quickly as @High Performance Lubricants has.

I always considered PP a top of the line Syn oil but these oil analysis reports really disappoint me. The add pack appears to be far weaker then it was in the past and not up to par with some other name brand oils.

Do any of you feel the same? Thoughts?

Yes. What additives that this oil does have is (from what I’ve seen) collected as sediment in the bottom of the oil bottle/jug. As said on here many times: “just shake it up”!
That’s not an oil or additive package that I want in my engine.
With that said it is still the most popular oil brand.
I’ve never been smart but it’s not for me…

There are plenty of tests to show them. You just can’t get the tests done for $30 because some of them take 20 hours or more, and the whole gamut of machines in the lab.

I don’t know the individual components, maybe HPL Dave or @Foxtrot08 would be willing to share some generalizations of additives that don’t show in a $30 oil analysis.

My post from the other day after a chat with Dave.
 
Here is a VOA of VME. This oil, per Valvoline at the time, outperformed their entire line of synthetic oils in high temperature testing and deposit prevention. This oil had a unique smell to it, and I attribute that to some type of exotic additive/base oil that wasn't showing up through a VOA that Valvoline claimed help reduce intake valve deposits. If cost is any indication, there was an expensive component in it. The oil ended up being discontinued due to price.

I wouldn't say Low or Mid SAPS is better than High SAPs, I would say they're just formulated differently for different needs.

My recent VOA has contributed to this. I will say, and I'm no expert, that after weighing all the info from this thread, I agree that the additive package should not be a concern on this oil. What does concern me a little is viscosity <9.3 on a 5W30 oil. We've seen this on a couple of VOAs recently: PP HM and M1 HM.

I often wondered why PP flash point is lower than most oils and if that really makes any difference?
