STAR BRITE Star Tron Ring Clean Plus fuel system cleaner — 16 oz (treats 160 gal), removes deposits & restores power

Star Tron Ring Clean Plus is an enzyme-enhanced fuel system cleaner that removes deposit build-up from rings, injectors, valves and combustion chambers to help restore engine power and efficiency.

If your gas-powered boat, motorcycle, car, truck or outdoor equipment is showing signs of sluggish throttle response, hard starts, or reduced fuel economy, this concentrated 16 oz treatment is formulated to address the problem. The proprietary enzyme package targets tough carbon and ethanol-related residues and helps prevent new deposits from forming, allowing fuel to combust more completely. One ounce treats ten gallons of fuel, so a single bottle is enough for broad maintenance coverage.

How quickly will I notice improved performance?

Most users observe smoother idling and crisper throttle response after one or two treatments, though heavily fouled engines may need repeated use. Effects depend on deposit severity and engine type.

• Typical improvement after 1–2 tankfuls for light to moderate deposits
• Severe build-up may require multiple treatments spaced over fuel fills
• Use every 4–5 tanks for preventive maintenance
• Works in all gasoline engines including small equipment

What parts of the engine does it clean and protect?

Ring Clean Plus is formulated to access the entire combustion system—cleaning injectors, intake valves, combustion chambers and piston rings. By reducing deposits in these areas, the product helps restore proper sealing, spray patterns and combustion efficiency.

• Dissolves carbon and varnish on injectors and valve faces
• Frees sticky or stuck piston rings to improve compression
• Clears combustion chamber deposits that cause knock and hot spots
• Improves spark plug cleanliness for more reliable ignition

Is this safe for my vehicle and how should I use it?

The formula is intended for gas engines and is safe when used as directed. Dosage is simple—add to the fuel tank at the recommended concentration and refill as usual; routine use keeps engines cleaner over time.

• Use 1 fluid ounce per 10 gallons of gasoline
• Treat every 4–5 tanks or as often as needed for maintenance
• Compatible with boats, motorcycles, cars, trucks, ATVs and small engines
• For best results, combine with Star Tron enzyme fuel treatment at fills

Can it help with ethanol-related fuel problems?

Yes — Ring Clean Plus contains components targeted at ethanol-blend issues, helping to break down the oxygenated-fuel residues that can accumulate more quickly in modern fuels. It improves fuel combustibility and can reduce symptoms linked to ethanol-induced deposits.

• Formulated to address ethanol-related deposit formation
• Helps restore cleaner combustion and reduce knocking
• May improve fuel economy by promoting more complete burn
• Works alongside regular enzyme fuel additives for ongoing protection

Who is this for: Star Tron Ring Clean Plus is designed for vehicle owners, marine operators, powersports riders and landscapers who want a concentrated, enzyme-based solution to remove deposits and maintain peak engine performance. If you service multiple gas engines or run equipment that sits between uses (boats, seasonal tools, motorcycles), this treatment delivers measurable cleaning power and long-term maintenance value. Proudly manufactured in the USA, the 16 oz bottle treats up to 160 gallons, making it a practical choice for both consumers and small fleets looking to reduce fuel-related performance issues without invasive engine work.
