Red Line® MT-90 75W90 GL-4 Gear Oil (similar to SAE 5W40/10W40 engine oil viscosity) is popular in Nissan, Mazda, Mitsubishi, VW/Audi, Lotus Elise/Exige, and Toyota applications. MT-90 offers quicker shifts, perfect synchronizer coefficient of friction, high performance gear protection and longer synchro life. Eliminates notchy shifting, even when cold. Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage. Satisifies the gear oil viscosity requirements of 75W, 80W and motor oil viscosities of SAE 40, 10W40, and 15W40. Recommended for GL-1, GL-3, and GL-4 applications, as well as where most special synchromesh fluids are specified.
