75W90 GL-4 gear oil (similar viscosity to SAE 5W40/10W40 motor oil) Popular in Nissan, Mazda, Mitsubishi, VW/Audi, Lotus Elise/Exige, Toyota, Mendeola transmissions and Atlas off-road transfer cases. Offers faster shifting, perfect synchronizing friction coefficient. Safe for brass synchronizers as it lacks the reactive sulfurs found in most GL-5 oils that cause damage. High-performance gear protection and longer synchronizer life Eliminates notchy shifting, even when it's cold Meets gear oil viscosity requirements of 75W90, 80W90, 90 and motor oil viscosities of SAE 40, 10W40 and 15W40. Recommended for GL-1, GL-3 and GL-4 applications, as well as where most specialty synchronizer fluids are specified. 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 maximum wear protection.
Friction coefficient appropriate for most manual transmission synchronizers (other synthetic gear oils are often too slippery for proper synchronized engagement) Red Line offers lubricants to meet almost all transmission applications MT-LV, MTL, MT-85 and MT-90 are not for use in differentials with hypoid gears Excellent gear and timing protection, balanced glide for easier shifting in cold weather Excellent for high and low mileage transmissions Compatible with petroleum and other synthetics.
