Both are Dexron "based" trans fluids. You can safely use that fluid on any MB auto trans!

If you have both MB (not synthetic) and Mobile 1 (synthetic) ATF which one would you prefer to use on a 600SEL 1992 and a 560SEL?

If you can get the "old" Mobil-1 formula ATF, I'd prefer that over the MB fluid. However, you really can't go wrong with the OE fluid from the dealership.

After further research on the "new" Mobil-1 fluid (Mercon V), I've decided that I don't want to use it in my Mercedes transmissions. It's not officially Dexron-approved.

If I'm not mistaken, they have stopped licensing Dexron, therefore no currently manufactured ATF can officially call itself Dexron any more.

I was looking for Dexron 3 recently and the stores had none. Lots of other ATF designations but no Dexron 3. What should I use to replace it?

You're looking for something that's officially approved for Dexron... the current revision is Dexron VI. Most standard fluids do have some kind of Dexron approval, it just may not say "Dexron III" since that's a relatively old spec.

Just use Amsoil or Redline.

That is very likely what I will end up doing. It's just that Mobil-1 was easier to obtain than Amsoil or Redline (and maybe a bit cheaper, too).

Mobil is currently selling Dexron VI "synthetic blend" ATF, so they must have some kind of current licensing deal:

Still looking for something with a more in-depth explanation.

FWIW...I used Castrol Transmax Z Fully Synthetic ATF during my recent C36 AMG transmission ATF fluid change. I am very impressed with the quicker gear engagement and silky smooth gear changes.
