Full Synthetic 75W90 GL-5 Gear Oil (5 gal) has Vis@100°C= 16.1 CSt, Vis@40°C= 112 CSt, Viscosity Index= 155, SAE Viscosity Grade= 75W90 (gear oil), ester base stocks, & friction modifiers for clutch-type limited slip differentials.

The Red Line 75W90 GL-5 Gear Oil is the go-to gear oil for most differentials. These GL-5 products contain the extreme pressure additives necessary for ultimate protection road cars and racing vehicles, as well as friction modifiers for proper limited-slip operation. This product is a full-synthetic formula blended with ester base stocks for shear stability, less gear noise and more consistent viscosity in warm and cold temperatures. Extreme pressure (EP) additives allow for use with hypoid gears and friction modifiers are included for use with limited-slip differentials. Not for use in most manual transmissions with synchronizers, as slipperiness may cause gear clash. It is the most popular Red Line gear oil, with thousands of applications for passenger cars, light trucks and racing vehicles. It 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. It is recommended for API GL-5, GL-6, MT-1, MIL-L-2105E, SAE J2360, and Chrysler spec MS-9763 and is a suitable replacement for a differential calling for an 80W90 or SAE 90 gear oil.

• High viscosity-index
• Relatively constant viscosity & film thickness with varying temp change
• Ester base stocks
• Friction modifiers
• Superior shear stability
• Less oxidation
