Differential oil and LSD additive
« on: October 14, 2018, 07:27:59 PM »
I'm going to change the rear differential oil in my '87 (which of course has a limited slip differential.)

I've heard that some diffs need more additive while some less; what's been your experience?

Most premium diff oils (Aimsoils, royal purples, shaffers, and a few others) already have the additive included. But i've never heard of any LSD needing "extra" additive then what is normally required
1999 Montero. 33x10.5x15 General X3's. 4.90's w/rear locker. Full armor. ADD idler arm. ADD 1.5" complete lift. Siberiean Bushings everywhere. 150W alternator with upgraded 4 AWG leads and grounds. 2nd Battery in the rear for camping stuffs to come.

Just get Mitsu 90W LSD oil and it's already figured out for you. Or if you want it tighter just run straight gear oil.
