Red Line GL-5 75W90 High Performance Gear Oil

Red Line GL-5 75W90
High Performance Gear Oil

Our most popular gear oil, this is the preferred product in nearly all car and light truck differentials, both conventional and limited-slip. 75W90 is excellent for most racing applications. It contains a friction modifier which is recommended for limited-slip units. 75W90 Gear Oil can be used in many transmissions and transaxles; however, other Red Line lubricants have better frictional properties for rapid synchronization.

• 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.

ABOUT RED LINE GEAR OIL FOR MANUAL TRANSMISSIONS

• Fully-synthetic formulas created from polyol ester base stocks, offer excellent lubrication under extreme conditions

• High viscosity-index (VI) to provide relatively constant viscosity and film thickness with varying temperature change

• Ester base stocks and friction modifiers provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears

• Superior shear stability and reduced oxidation compared to other synthetics and conventional gear oils

• Exceed API GL-5 specifications

• Engineered to provide the highest degree of protection and improvement of differential efficiency for better mileage, longer drain intervals, and less wear

RED LINE HIGH-PERFORMANCE GEAR OIL is a fully-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.
