Just a little FYI. I recently received a copy of MB Factory Approved Products and VERY surprisingly under approved transmission fluids, Mobil and Mobil 1 ATF is not listed. Castrol, Chevron, Citgo, Exxon Superflow, Havoline, Texaco, Pennzoil, Quakerstate, Sunoco, Unocal, and Valvoline are the only ATF listed as approved for MB automatic transmissions. This list was as of Nov. 2001. Mobil 1 motor oil is approved and required for FSS cars, but their transmission fluid doesn't make the grade. Things that make you go Hmmmmmm. BTW I changed my ATF to Mobil 1 also, but, before I got this listing from Mercedes. I'll admit I have thought of dumping it and using one of the approved ATFs
