Manual Transmission Fluid (Thread 2.1)

Pentosin's replacement for MTF2, FFL4, works great! I've tried it in 3 cars now.

Good to hear. I just worry about track use and high heat environments. Running MT90 in my ZF320 now. I tend to grind if I shift too fast. Same with the previous ZF320.

I'd love to use FFL4 since my E90 M3 is a DCT. Might give it a try soon.

I use Ravenol MTF-2 in my Z4M and it seems pretty good, even when cold. I selected it out of all the alternatives because it has a reasonable viscosity but also a very high viscosity index which comes into play when you’re talking about shifts from cold farther from 40C. The specs overall are top notch.

I ran the Motul DCTF in my M2 Comp 6MT but didn’t like it when cold. It did shift better when warm though.

Another Ravenol MTF-2 user here...currently have it in my Touring's 420G as well as our E46 zhp with the ZF GS6-37. It helped my 3rd gear "grunch" in the 420G when cold and overall improved shifting, I also ran this in the ZF-320 when I M52 swapped the E30, it was flawless at all temps.

Redline MT-LV is excellent
