Red Line 75W90 Gear Oil is designed to provide the highest degree of protection and greatest efficiency for your drivetrain. Red Line's drivetrain lubricants are optimized for differential, transmission, or transaxle use over a wide range of temperatures. Red Line Gear Oils contain polyol-ester base-stocks to provide excellent lubrication even under the 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, which means that Red Line Gear Oils will provide a stable viscosity for even extended periods of use.
Redline's 75W90 Gear Oil is a GL-5+ and GL-6 spec oil, and it's the preferred choice for conventional and LSD differentials. This gear oil contains limited-slip friction modifiers for decreased noise and better wear from clutch-type LSD units.
Suitable for street and light track - our recommended gear oil for most BMW applications. Heavily tracked cars can also use 75W110. M2/M3/M4/M5/M6 models from 2001 must use Red Line 75W140.
Fully-synthetic polyol ester base stocks -excellent lubrication under extreme conditions
High viscosity-index (VI) for consistent viscosity and film thickness with varying temperatures
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
Exceeds API GL-5 specifications
Sold per quart. Most BMW differentials take 1.3 liters (1.4 quarts).
