Red Line's MT-90 75W90 GL-4 gear oil (similar to SAE 5W40/10W40 engine oil viscosity) is the perfect choice for Nissan, Mazda, Mitsubishi, VW/Audi, Lotus Elise/Exige and Toyota manual transmissions.
MT-90 Offers quicker shifts, perfect synchronizer coefficient of friction and is safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that can cause damage - providing high performance gear protection and longer synchro life. Also eliminates notchy shifting, even when cold.
MT-90 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.
