Star Tron gasoline additive keeps fuel systems clean and helps to optimize engine performance.Enzyme-based additive increases fuel economy and engine power while reducing emissions. Stabilizes gas for short- and long-term periods of inactivity (up to two years) while preventing the formation of varnish. Eliminates carbon buildup in fuel delivery system and exhaust components. Disperses water throughout fuel so that it can be eliminated as engine runs, making it the perfect solution to prevent and eliminate ethanol (E-10) fuel problems.Key FeaturesStabilizes gasoline during periods of inactivityPrevents formation of sludge and varnishHelps to reduce fuel consumption and increase powerEnzyme-based formula works without toxic biocideFor use with any gasoline engineEight ounces treats 125 gallons of gas
