Star Tron Enzyme Fuel Treatment is a multifunctional fuel additive with a unique enzyme technology that allows all engines to start easily and run smoothly, even after sitting idle for months. Star Tron breaks down excess water and sludge to sub-micron size, allowing it to be safely burned away during normal engine operation. The additive increases fuel economy by cleaning the entire fuel delivery system, removing performance-robbing gum and varnish deposits, while modifying how fuel burns. This results in more complete and uniform combustion, maximum performance, increased fuel efficiency, reduced emissions, and reliable operation. Formula eliminates carbon buildup from burners, injectors, and exhaust components, plus it helps control biological growth without the use of poisons/biocides. Stabilizes fuel for up to 2 years.
