What oils to use

matt harvey · Aug 9, 2011

Ive got a 89 fender 90. Just giving it a full service as Ive just bought it. Went to buy new oil for my diffs and tranny box but completely forgot what oils it is I need. It's a lt77 box. Can someone remind me please?

u want some 10-40w for your engine oil if ur changing it.

Use Dextron III for the LT77 and 80/90W for the transfer box and axles (make sure it is GL4 and not GL5). I bought two sprayers and put extension hoses on the end to help fill the boxes. takes a little time but easy and relaxing (just watch for the spillage). The engine oil I used was a heavier 20W50 but it is in a 2.5 NA engine.
