Star Tron Enzyme Fuel Treatment is a multifunctional fuel additive which uses a unique enzyme technology that allows all engines to start easily and run smoothly, even when using ethanol-blended fuel or after sitting idle for months. Star Tron eliminates and prevents ethanol fuel problems. Star Tron breaks down excess water and sludge to sub-micron size, allowing it to be safely burned away during normal engine operation which helps prevent phase separation. Star Tron 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. Star Tron will stabilize fuel for up to two years, preventing the formation of gums and other solids that clog carburetors and fuel injectors. Star Tron can help rejuvenate old and sub-spec fuel.
