It seems that Mobil can't leave a good thing alone. They changed their Mobil-1 ATF recently to a new "Multi-Vehicle Formula". It has a distinctly different odor than either the previous formula, or the Mercedes ATF. What I don't like is the wording on the bottle - check out this text from the M-1 ATF "MVF" data sheet:

First, it says:
"Recommended by ExxonMobil for use in 2005 and earlier GM vehicles."

OK, that sounds fine for MB (Dexron) use. But the next sentence says:
"Mobil DEXRON-VI ATF is recommended for ... improved performance in 2005 and earlier GM vehicles."


So let me get this straight. It's The new M-1 ATF is "recommended" for pre-2005 GM vehicles (i.e., Dexron applications). But for "improved" performance in those same vehicles, we should use their NON-synthetic Dexron-VI fluid? What gives? Also, the new bottle mentions "Mercon" frequently, but says little about Dexron.

I managed to scrape up 7 quarts of the old M-1 ATF, and 1 quart of MB fluid, to use in my E500 tranny last night. I really don't like the acrid smell of the new stuff, along with the conflicting statements on the new bottle. Does anyone have more info on this new M-1 "MVF" ATF, or opinions in general...? BTW - the new stuff is also CHEAPER. Wal-Mart has it for $5.67/qt, where the previous M-1 ATF was closer to $7/qt.

Side question: Does anyone know if the OE/dealer fluid is synthetic fluid, or not? (Part # is 001-989-21-03-10, the bottle says "Made In Germany"). I'm VERY tempted to switch to either that (if it's synthetic), or Amsoil/RedLine ATF, for future trans fluid changes in my MB's.
