Pao levels of Edge EP vs M1 EP?

Not open for further replies.
Even a fairly thorough analysis by the PQIA or Russian Oil Club will not speculate as to the base stock composition of retail oils.
I suspect that somebody in the industry could take a good guess at the composition details based upon a really good VOA, but it would still be a guess.
 
OP

What grade? It s BIG product lineup. And what do you mean by synthetic? If you don't know why would you care?

5W30EP is not too high on M1 per their MSDS at 20-30% CAS# 68037-01-4

The 0w20 M1 EP appear to be the only Synthetic oil in M1 LINEUP for passenger cars 60-70% CAS# 68037-0104 PAO)

The rest are mainly petroleum oil based group III performance.

Have fun in the oil aisle

I would just try it and see if the car likes it.

I would go for the Magnatec or a Shell product

- I don't like the Ti additive package in anything Ive tried though its supposed to ne plus ultra.
Maybe id like it better on a worn in engine. Never tried it in that application.
 
Castrol Edge EP 0W20 PP is -38F, M1 EP 0W20 is -54F. Looks like the M1 (at least in 0W20) has more PAO-but only your engine, and UOA trend, will really know for sure which one works better for you, I wouldn't have any issues running either one to 10K in a clean engine.

Like ArcoGraphite said above, M1 EP 0w20 does have about 65% PAO (confirmed; I saw the SDS too).
Clever way to compare. Comparing Castrol Edge EP to Mobil by pour point should work well.
Castrol Edge EP 0w20 is actually listed as -43 deg F (not -38F, that figure is for black bottle only).

I found an MSDS on Edge black bottle 0w20, not their EP one, and it is indeed all GroupIII, no PAO... no surprise.
And Castrol Edge black bottle has a pour point of -38 degF.
Could be Castrol Edge EP gold bottle has very little PAO, based on the pour point comparison (black bottle to gold bottle Edge 0w20's).
