Motor oil for gasoline and diesel engines.
Royal Purple motor oils are recommended for use in all 4-cycle gasoline engines, and both 2-cycle and 4-cycle diesel applications including cars, trucks, motor homes/RVs, boats, commercial fleets, and stationary industrial diesel engines. Royal Purple motor oils are tough, long-life, high-performance oils that deliver superior protection and enhanced performance. They gain their performance advantages from a blend of synthetic oils plus Royal Purple's proprietary, synthetic Synerlec additive technology, which greatly reduces engine wear, including ring, cylinder, and bearing wear. They are extremely tenacious, adhere to engine surfaces, and remain after shutdown, which provides protection upon initial startup. Royal Purple motor oils also extend oil drain intervals. Less oil is purchased, and less oil is disposed of--it's good for your vehicle, and good for the environment. Multi-grade and straight-grade oils are available. Royal Purple motor oils are compatible with other mineral and synthetic motor oils.
