If you want smooth shifts and dont mind blowing up your transfer case, go ahead and use GL-4. We need GL-5 protection in our gearboxes because of the transfer case that uses the same fluid. Most GL-5 fluids are meant for differentials and do not offer any protection for our synchros. Ideally you want to use a 75/90 fluid that protects for GL-4 and GL-5 so that you can have synchro and transfer case protection. I've been doing quite a bit of digging around and it seems that Castrol Syntrax Universal would be a good match, but you cant get it in the US, so I just ordered some Silkolene Silktran SYN 5 which seems to fit our application as well. I wont know how well it works till I try it.
Use GL-5 Hypoid Diff Fluid in differential, do not use GL-4 in diff. Might as well just put water in it if you do!!
just my $0.02

You know what. Maybe we shouldn't use what the Subie guys use, and just see what the Evo guys use.
