Red Line 75W90 Gear Oil
 
Most popular Red Line gear oil, with thousands of applications for passenger cars, light trucks and racing vehicles
Contains additional friction modifiers for suitability with clutch-type limited slip differentials - for most LSDs, no additional friction modifiers are required
This product is not designed for use in most manual transmissions or transaxles in passenger vehicles, since the extreme slipperiness may cause synchronizer mesh issues that lead to shifting problems
Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E, SAE J2360 and Chrysler spec MS-9763
Suitable replacement for a differential calling for an 80W90 or SAE 90 gear oil
