Red Line MT-90 75W90 Synthetic Manual Transmission Oil (1 Qt.)
Red Line Synthetic Manual Transmission MT-90 Oil is designed to provide excellent protection and improved shift-ability for manual transmissions and transaxles, having cured the problem of hard shifting in thousands of transmissions with shifting troubles. It has the appropriate coefficient of friction for most manual transmission synchronizers (many gear oils, engine oils, and ATFs are too slippery for proper synchro engagement). The wide viscosity of MT-90 allows proper shifting over the entire temperature range which the transmission will experience. The Red Line Synthetic Manual Transmission MT-90 Oil oil has a very high viscosity index which provides relatively constant viscosity as temperature changes. MTL-90 is a low 75W at very low temperatures and a high 90W, at elevated temperatures, providing adequate viscosity to prevent wear and deaden gear noise. The shear stability and oxidation stability of these products are excellent, thus the physical characteristics of Red Line MT-90 will change little with use.
MT-90 is a 75W90 gear oil that is popular in Nissan, Mazda, Mitsubishi, Volkswagen, Audi, Lotus Elise/Exige and Toyota manual transmissions and transaxles as well.
