Mobil 1 has a link showing Zinc, Phosphorous and Manufacturer approvals in a nice table, linked below. Interestingly, the 0w20 offerings in the various flavours, with two exceptions ( M1 EP HM 0w20 and M1 HM 0w20 ), have lower PP and ZN levels than the other grades, including 5w20's.

Wonder why ? Are they using something else in these 0w20's ?

And, the motorcycle and racing lines have much higher levels of both, with more than double the amounts in the racing oils.

Formulations are developed using a precise balance of additives. It's chemistry. This is why I don't like mixing brands, although it is harmless for the most part. I think some have the tendency to think "more is better" or that they just throw these additives in the bottle and you're good to go. To your question, I don't know the answer. I do know the 0w20's have more PAO in them.

Check out the 0w40 one of their best Euro oils and good for most other engines also.

They are using different AW additives.

AW- likely Moly instead of Zn.

But to me, the proof is in the puddin' that Zn is the better AW additive because it goes in all applications where emissions isn't a concern but wear and performance is... whats that tell ya.


Just say NO to thin oils and M1!

No argument there, but are current engines wearing out because of current emission friendly lube oils?
I'm looking on Craigslist for cars for my grandchildren and I see a multitude of 150,000-200,000 mile vehicles.
And my own view is that most of the rigs heading for the last roundup (aka Pic a Part) have failed transmissions not engines.

Most all M1 tagged oils have Moly in the 70-80PPM range regardless of Z and P.. Have for a number of years.

It might tell you quite a bit, especially when you speak with professional engine builders who have torn their fair share of engines apart. A few I spoke with over the years favor higher levels zinc and phosphorus, contrary to what others believe.

I didn't realize M1 0/40 came in two formulas, FS and ESP I'd think the FS is more robust for my 'legacy' Toyota engines?
