This may have been covered before and I just missed it, so if I did someone please just point me in the right direction... but I have been searching the forms for the past two hours and have come up with not a lot.
So anyways, I was wondering what everyones favorite gear oils/lubes are for the EA81 4 speed trannys. So far it looks like Amsoil is a good choice from what I have read. I was hoping to be able to find something a little cheaper that I can get off the shelf that would work nearly as well. I know JesZek loves Motul 80W-90, but from what I have found online that stuff is insanely expensive for my thin wallet. Although Im sure it works like wonders.
Has anyone tried Royal Purpel's 75W-90 synchromax? I know its just about as spendy as Amsoil, but I am curious if anyone has any experience with it so we can compare. Right now I am running the walmart supertech 75W-90 and i want to get something a little higher quality in there so I can make this little tranny last.. and shift easier in the winter months
5-speeders are more than welcome to give their experience as well! As so far it looks like they take the same oil/lube as the 4spds...
