I have used the Maxlife fluid in several non-BMW cars and since my E53 didn't originally come with Dex VI, I decided to use the ML because it was economical and I THOUGHT it was slightly MORE viscous. It's actually very slightly LESS viscous than Dex VI. I don't know how it compares to the ZF fluid.

I don't know what to think about Nathan. I've watched several of his videos and appreciate him most of the time, but sometimes he'll make me cringe with his methods! He's got his opinions on stuff, like all of us, but I certainly wouldn't take his advice as gospel. Just my $0.02

AM.
