3.3TT Differential Fluid Change

[globalrebel]

Quick question to everyone . . .

Are you going with the Amsoil 75-90 'Severe Gear" oil, or the regular Long Life Synthetic? Just got my stinger and its been stock its whole life and serviced by Kia. So, want to pull the fluid and get the right stuff in there.

I used the Amsoil 75-90 Severe Gear and I have had no issues. It had enough friction modifiers for the LSD, that I didn't need to add any additives.

either one with LS additive already in it is fine

I went w/ Royal Purple 75w/90 about a year ago in my G70 w/ LSD, been quiet and performing well
Only caveat is it has a purple dye, I believe Redline also has a dye, so Amsoil probably the safest bet if you have warranty left on your Stinger or G70 so it wouldn't be obvious that you have aftermarket oil in there.

Yeah, it's been quiet the whole time, just changed the diff oil at 40k like the manual recommends, glad I did with the issues I've been hearing others have had.
