MSDS from Mobil.com. This is from the Japan site and the most recent MSDS is from June of 2012. Based on the MRV #'s, and high temperature ability of the AFE oil, I am not surprised it's 50% PAO, the rest Grp III+. *You can find Toyota "Castle SN 0w20", which may be TGMO in Japan? That MSDS says it's mostly Group III.

We've always know that AFE 0W-20 and 0W-30 for that matter must be PAO based in large part to acheive their very low MRV spec's although the SN version is not as low as the earlier SM oils. Since Mobil has moved away from PAO/ester to formulate the current version of M1 0W-40 in favour of GP III/AN, I wouldn't be surprised if Mobil decides to go the same route with their AFE oils at some point.

So which is better? 100% PAO or 50%? I guess that's like AFE vs Amsoil

I had a little back and forth with some guy in another thread about AFE vs other M1 offerings. My contention was that the metallic adds as seen in an XOM PDS were only a part of the story and that AFE had a superior basestock blend, based upon its cold temperature specs as well as UOAs seen here. Nice to have some confirmation.

I really like AFE 0w-20, just wish I was not sitting on 6 OCI's worth of oil, only one change is going to be AFE. But all the others will do the job just fine.

Not suprised at all, as said, to have MRV that is does, it would have to have a good chunk of PAO in it. A fill of this is going in the Tribute in the next couple of weeks precicely because of the cold-weather ability of this oil.

The Honda runs pretty much the same regardless of brand, but the SN 0w20/30 are the two best in terms of keeping the engine quiet on very cold starts. Lowest oil consumption with the 0w20. That performed no different from what I remember.

Looks like regular M1 5w30 also contains PAO.

It's really just for the purists that have to know or try to guess the base oils being used. LOL. Nothing new here as this has been posted before. It's what XOM has always said, they use high performance synthetic base oils.

Why would you make that assumption? Are they blended in the same place?
