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 synchroniser 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
These products contain the extreme pressure additives necessary for ultimate protection road cars and racing vehicles, as well as friction modifiers (except NS) for proper limited-slip operation
Fully-synthetic formulas created from polyol ester base stocks, offer excellent lubrication under extreme conditions
Ester base stocks and friction modifiers (except NS) provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears
High viscosity-index (VI) to provide relatively constant viscosity and film thickness with varying temperature change
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 synchronisers, as slipperiness may cause gear clash.
