I use to own a eclipse gsx and I alway put red line heavy weight shock proof gear oils in my tranny and rear diff. I wreck the gsx few week ago, and I still have 7 quart of redline gear oils, its ok to use on 1998 mustang gt rear diff ? thanks

That doesn't look like the right oil, the rear diff should have 75W90 (99.99 percent sure thats the right weight).

Sell it on ebay and get the right stuff. redline oils itself is a good brand.

i'm pretty sure you can use 80w90 too , but i know 75w90 is right lol

80w90 is a little on the thick side especially if you live up north in the winter time and plan on driving it, I would just sell it, but if you wanted to you could still use it.
