Product ReviewsLucas Oil 10048 75w90 Synthetic Gear Oil 1 Gal

Working great in my GM differential with G80 LS/LOCKER

I've used many lucas products before and they've always worked great for me, especially the upper cylinder lubricant. They say this 75w90 is good for limited slip and hypoid gears which perfect for my 2004 silverado which is a hybrid of both locked and limited slip. No additives needed.
