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. It provides excellent protection of gears and synchronizers, and its balanced slipperiness provides a perfect coefficient of friction, allowing for quicker shifting.
