Hi woodsyfeller. You need to use 80-90w gear oil. You can get it at wal mart or any marine supplier.

Stick with the marine grade. Think about it. Does the rear end in your vehical run under water??

this topic has been beaten to death in other posts, but its the ops choice, truck/car differentials get hot, cool down and condensate, obs are under water, they both get water from one way or another. just make sure its not leaking, and if it is......change it as often as is needed, or fix the leak! (for the few bucks its worth, i drain and change after every tank of fuel on my old motors....maybe a waste....but piece of mind!!)

To each his own, but I'll still stick with the marine grade.
