Red Line 50305 MT-90 75W-90 GL-4 Manual Transmission and Transaxle Lubricant (MTL) - 1 Gallon;

Red Line's Manual Transmission 90W Gear Oil is most popular in Nissan, Toyota and Mazda manual transmissions and transaxles as well as other selected applications. This is a 75W90 GL-4 Gear Oil that€s slightly heavier than MTL and provides excellent protection of gears and synchronizers and its balanced slipperiness provides a perfect coefficient of friction, allowing easier shifting. Red Line Oil's MTL and MT-90 allow proper shifting over the entire temperature range which the transmission will experience due to its wide viscosity. The synthetic base oils used have a very high viscosity index which provides relatively constant viscosity as temperature changes. MTL is a low 70W at very low temperatures and a high 80W, nearly an 85W, at elevated temperatures, providing adequate viscosity to prevent wear and deaden gear noise. MT-90 is a thicker 75W90 version of MTL. The shear stability and oxidation stability of these products are excellent, thus the physical characteristics of Red Line MTL and MT-90 will change little with use.
