Lucas Semi-Synthetic 2-Cycle Oil is a unique blend of mineral oil, synthetic oil, polybutene, and a low-ash additive system. The techs at Lucas pre-dilute this oil with a special solvent that facilitates mixing with gasoline at all temperatures. It's especially adept at preventing carbon deposits from forming on the piston rings, skirt, crown, and under crown areas. It's recommended for use in air and liquid cooled two-stroke engines such as snowmobiles, weed eaters, leaf blowers, chain saws, etc... and it works under all operating conditions. | Lucas Oil Semi-Synthetic 2-Cycle Oil | Size 1 qt
