Red Line Oil MT-90 is designed to provide excellent protection and improved shiftability for manual transmissions and transaxles, having cured the problem of hard shifting in thousands of transmissions with shifting troubles. They have 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 synthetic base oils used have a very high viscosity index which provides relatively constant viscosity as temperature changes. 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 MT-90 will change little with use.
' 75W90 GL-4 gear oil (similar to SAE 5W40/10W40 engine oil viscosity)
' Popular in Nissan, Mazda, Mitsubishi, VW/Audi, Lotus Elise/Exige, Toyota
' Offers quicker shifts, perfect synchronizer coefficient of friction
' Eliminates notchy shifting, even when cold
' Appropriate coefficient of friction for most manual transmission synchronizers (other's synthetic gear oils are often too slippery for proper synchro engagement)
