All true. But the smell indicates a change in the formula, not just the labeling/licensing. Also, as new engine & tranny fluid specs have been released over the past 20 years, they are almost always backwards compatible. For example, Dexron VI claims to supercede Dexron III. Fine, that's great.
So in that case, Mobil-1 ATF should also be rated as Dexron-VI approved and meeting Dexron VI specifications, which it is NOT. The pre-2006 GM vehicles basically means everything that used to specify earlier versions of Dexron ATF. Not sure about the Chrysler stuff, but I'm not lumping pre-2000 Mercedes in with "Chrysler". And no, I still haven't had time to call Mobil. Still want to do that however.
For the record, I'm not trying to argue one way or the other, I'm just trying to point out that:
(1) the M-1 ATF formula has changed,
(2) that M-1 ATF is no longer officially approved for Dexron III
or Dexron VI, and
(3) Mobil is now recommending a different ATF (
not Mobil-1) for all Dexron applications.
What you do with this information is your business, but personally I will not be using M-1 ATF in any of my Mercedes until it is formally and officially meeting Dexron specifications.
