HP 2-C is a high performance engine oil that improves performance and dramatically reduces wear in two-cycle gasoline engines. Its recommended for use in both pre-mixed and oil injected gasoline two-cycle engines in outboard motors, motorcycles, jet skis, chain saws, etc. HP 2-C increases horsepower and reduces fuel consumption, heat, wear and emissions. Its synthetic solvency keeps spark plugs and exhaust ports clean as well. Its performance advantages come from a blend of synthetic oils plus Royal Purples proprietary Synerlec additive technology. Synerlec significantly increases the oil film strength for optimum engine efficiency and maximum protection. HP 2-C is suitable for premix in snowmobiles, however, due to cold soak (low temperature pumpability issues with oil injected.
