Premium Gear Oil for Automotive Use

ROYAL PURPLE's Max Gear is a high-performance, ultra-tough synthetic gear oil designed to provide maximum protection for heavily loaded gears. This gear oil excels in axles containing open, limited-slip, locker, and spool-equipped differentials. Max Gear is also recommended for use in truck and automotive front or rear differentials, manual transmissions, and the lower gear units of marine engines that specify the use of an API GL-5 or GL-4 fluid.

Remarkably, Max Gear is non-corrosive to soft yellow metals, such as brass, bronze, and copper, making it safe for use in manual transmissions with synchronizers. The cushioning molecules in Max Gear absorb gear impact to prevent fatigue and minimize wear. Moreover, this gear oil significantly reduces friction, which lowers gearbox temperatures, extends equipment life, and improves fuel efficiency.

By combining the highest quality synthetic oils with ROYAL PURPLE's proprietary Synerlec additive technology, Max Gear outperforms ordinary gear oils. This exceptional formulation ensures that gears run smoother, quieter, cooler, and longer without overhauls. Max Gear is also formulated with a hypoid friction modifier additive, which is necessary for use in clutch or cone-type differentials.

One of the key benefits of Max Gear is its greater wear protection for severe service performance. This gear oil boasts excellent high-temperature performance and low-temperature fluidity, ensuring reliable operation in a wide range of operating conditions. Additionally, Max Gear's excellent water separation prevents corrosion, further extending the lifespan of critical components.

With a lower coefficient of friction, Max Gear delivers enhanced efficiency, contributing to improved fuel economy and reduced energy consumption. This makes it an ideal choice for a variety of applications, including truck and automotive front or rear differentials, manual transmissions, and the lower gear units of marine engines.

It's important to note that no additional additives are necessary when using Max Gear, as it already contains the friction modifier additive required for limited-slip differentials. However, this product is not suitable for use in wet-clutch systems, such as those commonly found in motorcycles, ATVs, and some marine drive units.

In summary, ROYAL PURPLE's Max Gear 75W-90 High Performance Synthetic Automotive Gear Oil is a superior choice for those seeking maximum protection and performance for their heavily loaded gears. This gear oil, available in a case of 6 quarts, is compatible with other oils and delivers exceptional results in a wide range of applications.
