Hello, anyone using Mobil tranny fluid? i've heard mixed opinions about BG, redline, royal purple, motul, synchromesh...etc.
but, haven't heard about mobil one tranny fluid.
any inputs??
thanks in advance.

 

use whatever you want as long it's GL-4 approved which I don't think Mobil is

 

what is GL-4?

i just changed my tranny fluid to mobil-1 synthetic 75w90...

 

mobil 1 is gl5. however, a few members on here especially me have used it. I didnt have a problem with it. I used it for about 6-7k miles. then my clutch started slipping so I put an act clutch heavy duty sd, ss clutchline and redline synthetic and now its even better. good luck.

 

I have been running Mobil1 20w-50 in my VR4's transmission. On 3si.org, It is a common thing to do to help with the syncro's. I have not had a single issue with it and the trans shifts wonderfully.
