Hot Shot's Secret Gasoline Extreme is now infused with Hot Shot's Secret LX4, a lubricity additive that prevents wear and provides fuel system protection. It also acts as an upper cylinder lubricant. The one-tank formula features a Polyetheramine (PEA) detergent to thoroughly clean valves, pumps, injectors, rings, pistons, and upper cylinders. Developed for multiple purposes, the fuel additive dissolves power-robbing gum and varnish and removes combustion chamber deposits to restore power, performance, and fuel mileage. The new formulation is available in a new easy-to-pour 12 oz. bottle design that is compatible with capless fuel tanks. One 12 oz. bottle can be used to treat 20 gallons of gasoline.
