The most popular Red Line gear oil. Fully synthetic, offering excellent lubrication under extreme conditions (US Quart, US Gallon)
Red Line 75W/90 is the most popular Red Line gear oil, with thousands of applications.  It's fully-synthetic formula created from polyol ester base stocks, offers excellent lubrication under extreme conditions.

Red Line 75W/90 contains additional friction modifiers for suitability with clutch-type limited slip differentials - for most LSDs, no additional friction modifiers are required.

Red Line 75W/90 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
  • 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
  • Engineered to provide the highest degree of protection and improvement of differential efficiency for better mileage, longer drain intervals, and less wear.
