Royal PurpleŽ 2-Cycle TCW III is recommended for use in both pre-mixed and oil injected gasoline two-cycle engines in outboard motors, motorcycles, jet skis, chain saws, etc. Royal PurpleŽ 2-Cycle TCW III is a high performance engine oil that improves performance and reduces wear in both standard and high performance two-cycle gasoline engines. Royal PurpleŽ 2-Cycle TCW III's synthetic solvency keeps spark plugs and exhaust ports clean for maximum engine efficiency. This engine cleanliness combined with Royal PurpleŽ 2-Cycle TCW III's low coefficient of friction promotes increased horsepower and engine speed. Engines operate with greater combustion efficiency and go longer between overhauls when lubricated with Royal PurpleŽ 2-Cycle TCW III. Royal Purple 2-Cycle TCW IIIŽ is suitable for premix in snowmobiles but due to cold soak (low temperature pumpability issues on oil injected snowmobiles) Royal Purple Snow 2-C is recommended for operation in temperatures below 20° F.
