Clear allMax Gear 75W-90 Synthetic Gear Oil
Max Gear 75W-90 is recommended for use in truck and automotive front or rear differentials, manual transmissions and lower gear units of marine engines that specify the use of an API GL-5 or GL-4 fluid. It is non-corrosive to soft yellow metals (brass, bronze, copper, etc.) and synchronizer safe. Specially designed to extend gear and bearing life, Max Gear provides superior corrosion protection over competing conventional and synthetic gear oils. We engineered this ultra-tough, high performance automotive hypoid gear oil to provide maximum protection to heavily loaded gears while maximizing power throughout the drive train. Above all, Max Gear outperforms ordinary gear oils by combining the highest quality synthetic oils with Royal Purple’s proprietary Synerlec® additive technology. As a result, Max Gear makes gears run smoother, quieter, cooler and longer without overhauls. A direct reduction of drag in the drive train has a huge advantage for trucks and other 4-wheel drive vehicles, therefore, better gas mileage. Formulated with a friction modifier additive, therefore no additional additives are necessary. Max Gear is available in the following viscosities: 75W-90, 75W-140, 80W-90, 85W-140 and SAE 90
MAX GEAR 75W-90 HIGH PERFORMANCE GEAR OIL ADVANTAGES
- Maximizes horsepower

MT-85 75W85 GL-4 - Quart
- Recommended for Nissan 350Z and 370Z (also most Maxima, Altima & Sentra), Mitsubishi Evolution, Hyundai, Kia and Quaife synchro manual trans applications
- Many NV4500 truck transmission applications like Chevy Silverado and Dodge Ram, for Chrysler spec MS-9070
- Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage
- Offers quicker shifts, a perfect synchronizer coefficient of friction
- Eliminates notchy shifting, even when cold
- High performance gear protection and longer synchro life
- Recommended for GL-1, GL-3 and GL-4 applications as well as where most special synchromesh fluids are specified
- Satisfies the gear oil viscosity requirements of 85W, 75W85 and motor oil viscosities of SAE 30 and 5W30
-
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 petroleums and other synthetics
