Lucas Oil 10115 Semi-Synthetic 2-Cycle Oil - 1 Gallon Jug Lucas High Performance Semi-Synthetic 2-Cycle Oil has been specifically developed to give a long trouble-free life to gasoline-powered 2-cycle engines. Designed for any oil injection system or pre mix up to 50:1. Use in Snowmobiles, Weed Eaters, Leaf Blowers, Chain Saws and more. Lucas High Performance Semi-Synthetic 2-Cycle Oil uses an advanced "Smokeless" formula specially blended from mineral oil, synthetic oil and a low ash additive package containing fortified dispersant inhibitors. It also contains exclusive detergents and lubricants. The end result of this advanced technology is a more thorough burning of the fuel resulting in more power and fewer emissions.
