Red line 80W140 synthetic gear oil is designed for heavy duty and high temperature non synchromesh manual transmissions or differentials in road or race applications where outright power is not as critical. Contains friction modifiers making it suitable for use in vehicles with clutch type limited slip differentials (LSD's).Fully synthetic formula provides excellent lubrication even under extreme conditionsGives constant viscosity and film thickness across a wide temperature range Lowers operating temperaturesImproves differential efficiency, increasing service life and drain intervalsSuitable for vehicles fitted with clutch type LSD'sSpecifications: API GL-5 +Recommendations: AP GL-5, GL-6, MT-1, MIL-L-2105E, SAE J2360 1 quart (0.94 litre) bottleTechnical Data Sheet
