Its time to replace the rear end gear oil. I was going to buy Redline 75w140 Syn. This gear oil already has the additive for the clutches. Should I put in separate limited slip additive or trust Redline.
That's not the right oil. I believe it's 80/90W. Plus additive. Unless your rear end is old like mine then you need to forget the additive or it won't grip at all.
