Engine Oil

Duralec Super motor oil by Royal Purple is a high-performance synthetic engine oil made for those diesel engines requiring the use of an emissions compliant oil for the 2007 and 2010 emissions equipment such as DPF’s, Catalytic Converters, EGR, and SCR injection with the ultra-low sulfur diesel fuels found in North America and Europe. Duralec Super motor oil is specifically formulated to maximize component life and improve fuel performance with excellent high-temperature breakdown resistance and low temperature pumpability to minimize cold induced startup wear.

Fuel Additive

Royal Purple Max-Tane is formulated for year-round use in all types of light, medium and heavy duty diesel engines, and is compatible with any type or grade of diesel fuel, biodiesel, and ultra-low-sulfur diesel. Max-Tane is specifically formulated to solve problems associated with today’s new High Pressure Common Rail diesel injection systems. Safe for use with all types of diesel exhaust emission systems equipment, including diesel particulate filters and catalytic converters.

Gear Oil

Royal Purple Max Gear is recommended for use in automotive front and rear differentials, manual transmissions and transfer cases that specify use of an API GL-5 or GL-4 fluid. It is noncorrosive to soft yellow metals (brass, bronze, copper), and is synchronizer safe. Max Gear is an ultra-tough, high performance gear oil designed to provide maximum protection to heavily loaded gears while maximizing power throughout the drivetrain. Max Gear outperforms ordinary gear oils by combining the highest quality synthetic oils with Royal Purple’s proprietary Synerlec additive technology. Max Gear makes gears run smoother, quieter, cooler, and longer.

Transmission Fluid

Royal Purple Max ATF is a synthetic, high performance, long life, multi-vehicle automatic transmission fluid. Its superior formulation has optimized viscosity, antifoaming, and protection against wear and thermal breakdown for six to ten speed transmissions commonly found in late model passenger cars and light trucks. Max ATF provides excellent torque holding capacity to dramatically reduce slippage and heat generation. Automatic transmissions generate a great deal of heat and depend on the transmission fluid for cooling and protection. That’s why Royal Purple is trusted and backed by enthusiasts all over the world, the high-quality Royal Purple Engine Oil, Gear Oil, ATF, and other lubricants.
