FULL-SYNTHETIC FORMULAS - created from polyol ester base stocks, offer excellent lubrication under extreme conditions | CONTAINS - additional friction modifiers for suitability with clutch-type limited slip differentials - for most LSDs, no additional friction modifiers are required | NOT DESIGNED - for use in most manual transmissions or transaxles, since the extreme slipperiness may cause synchronizer mesh issues that lead to shifting problems | POPULAR GEAR OIL FOR - API GL-5, GL-6, MT-1, MIL-L-2105E and SAE J2360, also for cars and light trucks like Ford Mustang and F-150, Toyota Tundra and Sequoia, Jeep Cherokee and Dodge Ram | WHY RED LINE - Established in 1979, Red Line Products perform & protect better than any on the market. No compromises
This Red Line synthetic gear oil does its job well, but I feel like it's a bit on the expensive side compared to others I've used. It does help with the smooth operation of my limited-slip diff, but that price tag makes me hesitant to buy in bulk.

Smooth shifting and great protection
I've been using Red Line's synthetic gear oil for a while now in my car, and I love it. The 75W140 viscosity is perfect for my limited-slip differential, making shifting buttery smooth. I'm definitely sticking with this brand for my future maintenance.

Great for my differential needs
I picked up the Red Line 75W140 GL-5 synthetic gear oil for my truck's hypoid limited-slip differential, and it works like a charm. The performance is noticeable, especially in colder weather. Definitely a solid choice if you're looking for reliability in a 1-quart pack.

Not the best for my setup
I bought the Red Line 75W140 for my differential, but it didn't perform as expected. I had some issues with slippage after using it, which was disappointing. The packaging was fine and it arrived on time, but I'm not sold on this oil.
