Well i brought 2 bottles of Redline 75W90 high performance gear oil, i was wonderin if i can use this in my differential which has LSD in it.
Correct, this is for gear oil that does not already have LSD additive in it. As someone mentioned, redline 75w90 already has this additive in it and should be perfectly fine in your differential. I am running Redline Heavy Shockproof Gear Oil (arizona is hot enough) and it has worked great. I have also heard REALLY good things about gm syncromesh, however I do not know if it has lsd additive in it. Perhaps someone could chime in on this? (too tired to google).NegativeGeForce said:i have read that just adding straight gear oil and then slowy adding lsd friction modifier till the rearend stops poping is the best thing to do. I am sure someone can clarify this better then I can.
