1998 Yukon Rear Dif Oil Change

[Jazz]

Hey all,

I'm hearing that the Mobile 1 Symthetic 75-90w is ok to put in the rear differential, regardless of whether or not you have a G80. (At this point I don't know if I have one or not)

They sell it everywhere- safe enough to use?

Thanks!

can be used with a g80. so go to it.

In your glove box is a list of three digit codes, if one is G80 you've got one

We use this additive in the Grand National G80s as well ...
