Re. 229.51 spec oils
Hi, I'm trying to sort through a few things. Your spec sheet for M1 0W40 doesn't show that it meets 229.51 oil spec, yet the product in the store does. Somebody might want to address that.
We've heard that the new 5W40 Formula M oil is no longer recommended for Mercedes gas cars and is only to be used in the diesels. There was a TSB issued and they also claim they're reverting to M1 0W40 for their bulk oil. We've heard that there's some problem with (all) 229.51 spec oils and gas cars running ethanol blended fuels. Any comments on what the issues/concerns are?
Also, how can MBUSA be reverting to M1 0W40 for their bulk oil if it too covers 229.51??
Thank you for your inquiry.
Mobil 1 0W-40 does not claim MB 229.51 but MB 229.5 and that should be consistent with the PDS and the label per the information we have.
We are checking on the question regarding Mobil 1 Formula M 5W-40 for gasoline engines. Mercedes-Benz may be making changes in that regards, but at this time we do not have their final decision.

...and there you have it!
Pennzoil said closely to this:
According to my reference material your vehicle requires a Mercedes-Benz P/N 001-989-21-03-10 (Shell 3403-M 115) atf. This product is not available in the U.S. except at dealerships.

Amsoil does have a product that they claim meets the spec. But so far it is Amsoil or MB dealer for transmission fluid.

Use RP MAX-ATF in your Power Steering.
Use RP MAX-Gear in your rearend diff.
Use factory MB Oil in your Trans. ONLY!!

I have also read that it reduces carbon buildup in the engine, but I can't physically confirm that.
