RED LINE Synthetic Gear Oil 80w-140 GL5
RED LINE SYNTHETIC GEAR OILS are designed to provide the highest degree of protection and greatest efficiency for your drivetrain. Red Line provides a complete line of drivetrain 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. Red Line Gear Oils contain polyol ester base stocks, the only lubricants which can withstand the tremendous heat of modern jet engines, which makes our products provide excellent lubrication even under extreme conditions of high-loading and high-temperatures. The natural lubricity of the polyol esters provide excellent slipperiness which reduces the sliding friction in hypoid gears - reducing wear and significantly reducing temperatures. The synthetic basestocks have a natural multigrade property, so large amounts of unstable thickeners are not required to manufacture our gear oils, which means that Red Line Gear Oils will provide a stable viscosity for even extended periods of use. Red Line formulates more extreme-pressure protection into the gear oils than other petroleum and synthetic manufacturers which provides wear protection over a wider range of temperatures and performance conditions - ranging from high-torque and low-speed situations to very high-speed conditions with shock loading.
Generally used in commercial trucks which will climb long, steep grades and some racing applications where power is not critical.
Generally 0.5% less efficient that 75W90. Can also be used in differentials and transmissions where excessive noise is a problem and limited-slip differentials which vibrate excessively when turning a corner.
