Red Line MT-90 75W90 Transmission Gear Oil GL-4 (5 Gallon) 50306

Red Line MT-90 is a 75W90 GL-4 synthetic gear oil designed for manual transmissions and transaxles. It offers improved gear and synchronizer protection compared to other MTL (Manual Transmission Light) lubricants. This GL-4 oil is suitable for applications recommending GL-1, GL-3, and GL-4 gear oils, including those specifying special synchromesh fluids.

Similar in viscosity to SAE 5W40/10W40 engine oil, Red Line MT-90 provides smooth gear changes due to its balanced coefficient of friction. This prevents notchy shifting, even in cold weather. Notably, it is safe for transmissions with brass synchronizers, unlike some GL-5 oils that can cause damage. Applications include Nissan, Mazda, Toyota, Mitsubishi, VW/Audi, Lotus Elise/Exige transmissions, and Atlas transfer cases.
