Description
Red Line MT-90 is a 75W90 GL-4 synthetic gear oil designed for manual transmissions and transaxles. While similar in viscosity to some motor oils (SAE 5W40/10W40), it offers superior protection for gears and synchronizers. MT-90 is known for its ability to improve shifting, especially in cold weather, due to its balanced coefficient of friction. This makes it a popular choice for Nissan, Mazda, Toyota and other transmissions that require a GL-4 lubricant. Unlike some GL-5 oils, MT-90 is safe for transmissions with brass synchronizers because it lacks reactive sulfurs that can cause damage. In addition to its performance benefits, MT-90 offers extended synchronizer life and smooth gear changes. It meets the viscosity requirements of various gear oils (75W90, 80W90, 90) and motor oils (SAE 40, 10W40, 15W40) making it a versatile option for transmissions requiring GL-1, GL-3, GL-4 or specific synchromesh fluids.
Since most GL-5 gear oils for differentials are too slippery for manual transmissions, Red Line offers these products that ensure proper shifting while providing ultimate wear protection
Appropriate coefficient of friction for most manual transmission synchronizers (other's synthetic gear oils are often too slippery for proper synchro engagement)
Red Line offers lubricants to pinpoint nearly every transmission application
MT-LV, MTL, MT-85 & MT-90 are not for use in differentials with hypoid gears
Excellent gear and synchro protection, balanced slipperiness for easier shifting in cold climates
Excellent for high- and low-mile transmissions
Compatible with petroleum and other synthetics
