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.

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

Overdosing is not harmful.

I’ve tested many products and this seems to be the only product that can keep Ethanol at bay. In fact, I’ve treated 10% Ethanol Gasoline with this and it held up for over two years. It is a must-have for anyone with small engines, boats, or anything that you burn gasoline in. It is the best product for the job, and works phenomenally.

While we’re all forced to use crap gasoline, I’m thankful that Star Tron has developed a great cocktail that helps to remove the destructive effects of this EPA-mandated garbage. Don’t think twice, buy the big bottle, and mix it with anything that contains Ethanol. You’ll be glad you did when you get those engines running next year and don’t have to chase down problems!


It especially works great for all engines that may sit for quite some time between uses, it keeps the gas from separating and varnishing.

I use it extensively in my 2-cycle engines to keep the small hoses soft for years–I typically get 2-3 years out of my trimmer fuel lines now as compared to 8-12mos without.

All my engines start right up now with no need to ‘pull till I drop’ anymore.

I use in my vehicles as a preventive measure though I haven’t noticed any difference with/without–more fear of the horror stories from others in regards to the damage Ethanol causes…
