Red Line 75W90 Gear Oil 1 Quart

Red Line’s Gear Lubricants are designed to provide the highest degree of protection and greatest efficiency for your drive train. Red Line provides a complete line of drive train lubricants which are optimized for differential, transmission, or transaxle use over a wide range of temperatures. Proper selection depends upon the manufacturers’ requirements and whether the application is for passenger automotive, commercial, or racing use.

This oil is recommended for Subaru differentials.

Red Line Gear Oils contain polyol ester base stocks to provide excellent lubrication even under extreme conditions of high-loading and high- temperatures–their natural lubricity provide excellent slipperiness which reduces the sliding friction in hypoid gears to reduce wear and temperatures. The synthetic base stocks have a natural multi-grade property, so large amounts of unstable thickeners are not required to manufacture their gear oils, which means that Red Line Gear Oils will provide a stable viscosity for even extended periods of use. Red Line also manufactures gear oils which can be used in limited-slip differentials without the use of additional friction modifiers.

The Red Line 75W90 is the most popular gear oil, this is the preferred product in nearly all car and light truck differentials, both conventional and limited-slip. 75W90 is preferred for most racing applications. It contains 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. Exceeds API GL-5.
