New from Red Line Oil is MT-85, the latest in a full-synthetic family of products for manual transmissions and transaxles. This 75W85 GL-4 gear oil is designed to fill the viscosity gap between MTL (70W80 GL-4) and MT-90 (75W90 GL-4), perfect for many Nissan, Mitsubishi, Hyundai, Kia and NV4500 pickup truck transmission applications. This product is safe for brass synchros, as it lacks the damaging, reactive sulfurs found in most GL-5 oils. MT-85 satisfies the gear oil viscosity requirements of 75W and 85W as well as SAE 30 and 5W30 motor oil viscosities. Recommended for GL-1, GL-3, and GL-4 applications, as well as where most special synchromesh fluids are specified.
