Hmm, was just checking the Redline site.

For the 1M they list D6, but for my '13 135i they list D4, even though they have the same transmission. The listing for the 135i must be wrong for that year.

Looking for a synthetic fluid for my trans, the LT-5 is REALLY thick at -30. Even after changing it just 8000 km ago.

Going to call Redline about it.

Edit: Looking at the Redline site some more, looks like they recommend D6 for the N54 and the 1M, and D4 for the N55 cars.

Now I am even more confused. Guess the listing for the 1M is wrong!??!?
