Hey guys I've been looking at Mobil 1 synthetic 75w90 gear oil for my RB. Would this be a wise choice. I have been searching for quite a while and I just can't seem to get the answers for what I'm looking for. Any help is greatly appreciated thank you.

I use mt90 in my rb tranny, seems to like it.

I think theres a multiple page thread about gear oil as well.

Amsoil 75w90 when I had my rb. Never had any problems.

That Mobil synthetic gear oil is GL-5 and I thought I had read somewhere that RB transmissions like GL-4 better. I think its because GL5 is bad for brass synchros. I will update with a link if I can find it.

I got some AMSOIL 75W-90 Synthetic GL-4 it works great.

Also you need ~3.75L of fluid to fill the transmission.

Ok I'll definetly check into amsoil today thanks guys

I used mobil 1 and my trans would be notchy before it warmed up - about 2-3 miles. So someone recommended Motul, and I will never buy any other gear oil again.
