Royal PurpleŒ¬ 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 PurpleŒ¬ 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 PurpleŒ¬ 2-Cycle TCW III's synthetic solvency keeps spark plugs and exhaust ports clean for maximum engine efficiency. This engine cleanliness combined with Royal PurpleŒ¬ 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 PurpleŒ¬ 2-Cycle TCW III. Royal Purple 2-Cycle TCW IIIŒ¬ is suitable for premix in snowmobiles but due to cold soak (low temperature pumpability issues on oil injected snowmobiles) Royal Purple Snow 2-Cä‹¢ is recommended for operation in temperatures below 20ŒÁ F.
