Star Tron Enzyme Fuel Treatment - Concentrated Marine Formula - Gasoline

Star Tron Enzyme Fuel Treatment is a multifunctional fuel additive which uses a unique enzyme technology. Helps all engines start easily and run smoothly, even when using ethanol-blended fuel or after sitting idle for months.

Cures 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.

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.

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.

Recommended Uses

Star Tron can be used in all gas outboards, inboards, cars, trucks, motorcycles, ATVS, snowmobiles, small engines, outdoor power equipment including pre-mix fuel engines. Star Tron is safe for all engines, will not harm oxygen sensors, and overdosing is not harmful.

Directions

Initial Dosage: Add 1 fl. oz. (30 ml) for every 8 gallons (30 L) of gas.

Refill: Add 1 fl. oz. (30 ml) for every 16 gallons (60 L) of gas.

Overdosing is not harmful.

  • Makes all engines start easily, run smoothly; improves performance
