Star Tron Enzyme Fuel Treatment Concentrate – Designed to Help stabilize Gasoline and Support Ethanol Fuel Performance

What It Is

Star Tron Enzyme Fuel Treatment Concentrate is a gasoline additive that stabilizes fuel and helps engines run cleaner by breaking down ethanol-related deposits and moisture. It’s designed for small engines in lawn mowers, tractors, trimmers, and other outdoor power equipment.

Fitment & Compatibility

• No physical fitment – this is a liquid treatment, not a mechanical part.
• Fuel type – works with all gasoline grades (E10, E15, ethanol-free, and blended). Works in 2-cycle and 4-cycle engines.
• Dosage – 1 oz treats up to 8 gallons of fuel. Use the entire bottle (8 oz) for 64 gallons.
• Storage – shelf-stable for 5+ years unopened; treat fuel within 30 days of purchase for best results.
• Check before buying – confirm your engine uses gasoline (not diesel) and that you can measure small doses accurately. Not for diesel or oil-fuel mixes.

Key Things to Know

• Enzyme-based, not solvent-based – it digests ethanol varnish and water, unlike stabilizers that only prevent new deposits.
• Easy to use – pour directly into fuel tank or mix with gas in a can. No special tools or engine disassembly.
• Works as a cleaner too – can help restore performance in engines that have sat with old fuel, but may require multiple treatments for heavy gum.
• Dosage matters – over-treating won’t harm the engine, but under-treating reduces effectiveness. Use the measuring cap included.

Should You Buy It

Buy this if you use ethanol-blended gas in your mower and want to prevent fuel system issues from sitting over winter or between uses. It’s especially useful for seasonal equipment, or if you’ve had carburetor problems before. Skip it if you always use ethanol-free fuel or run your mower year-round without storage.
