Engine/Transmission (1998.5 - 2002) gear oil question

[Steve Robinson]

Anyone know what gear oil to put in a 98. 5 manual 5 speed. Is it a multi-grade or is it 90 weight? Thanks for the help.

Steve,
If it is for NV 4500 tnans. ,USE MOPAR OIL 0NLY, Otherwise you run the risk of trans. The oil is a special blend almost like autotrany fluid. For the Dana diff. ,I run Amsoil 75-90 syn. I used up four NV 4500`s in 98. 5 in 400000mi, first one because of wrong oil when I changed it at 25000mi.
Good Luck

I have been running Royal Purple in my NV4500 and the rear end since new without any problems. I have 75-90 in the transmission and 75-140 in the rear with change intervals every year which is about 25k miles. Currently have over 260k miles and everything runs great.

I used to use Amsoil in my 99. But I don't exactly remember the type or weight. I still have some somewhere I think. I do remember it was blue. Seemed to work great for a few years until I sold it.
