Quicksilver Quickare Fuel Treatment 12 oz — Concentrated Cleaner & Stabilizer for Gasoline Engines

Quicksilver Quickare Fuel Treatment is a concentrated 12 oz formula that cleans deposits, stabilizes gasoline and protects both 2‑cycle and 4‑cycle engines from corrosion and ethanol-related issues.

Designed for a wide range of gasoline-powered machines—from cars and trucks to motorcycles, lawn equipment and marine motors—this fuel treatment addresses common fuel-related performance problems. It works with all grades of gasoline and ethanol blends to disperse varnish and gum, inhibit corrosion, and reduce the risk of phase separation in stored fuel. Safe for catalyzed engines, Quickare helps maintain reliable starts and smoother operation while prolonging the usable life of fuel in tanks.

How does Quickare improve engine performance?

The formula dissolves existing varnish and gum deposits that restrict fuel flow and foul components such as carburetors and injectors. By keeping fuel passages clean, engines run more efficiently, idle smoother and respond better under load. Regular use helps maintain consistent combustion and reduces hesitation caused by clogged fuel delivery parts.

• Breaks down varnish and gum in carburetors, injectors and tanks
• Restores proper fuel flow to intake valves and spark plugs
• Supports stable combustion across gasoline grades

Will this treatment protect fuel during storage?

Yes—Quickare contains stabilizing ingredients that slow chemical breakdown in gasoline and help prevent ethanol-related phase separation. Treated fuel stays usable longer, which reduces fuel system damage and the need for costly cleaning after extended storage. It’s useful for seasonal equipment and boats that sit idle for weeks or months.

• Keeps fuel fresh for up to three months
• Reduces moisture-related phase separation with ethanol blends
• Minimizes gumming during off-season storage

Is it safe for all gasoline engines and emissions systems?

Quickare is formulated for both 2‑ and 4‑cycle gasoline engines, and it’s compatible with carbureted and fuel‑injected systems. The product is safe for engines equipped with catalytic converters when used as directed, so you can treat passenger vehicles as well as small engines without harming emissions hardware.

• Suitable for carbureted and fuel‑injected engines
• Safe for catalyzed exhaust systems when used per instructions
• Works on a broad list of equipment: autos, motorcycles, ATVs, mowers, chainsaws and marine engines

How often should I use Quickare for best results?

For routine maintenance, you can add the treatment at every fill‑up to keep fuel systems continually clean and protected. For stored equipment or engines showing deposit-related issues, treat the tank before storage or follow a recommended service interval based on use. Using it regularly reduces buildup and minimizes the need for aggressive mechanical cleaning.

• Add at every tank fill-up for continuous protection
• Use before seasonal storage or long idle periods
• Apply when experiencing rough idle, hard starting or reduced performance

Who this product is for: Quicksilver Quickare Fuel Treatment suits owners and technicians who maintain a variety of gasoline engines—drivers, boaters, landscapers and powersports enthusiasts—who want an easy preventive solution for fuel degradation and deposit buildup. It’s a practical choice for anyone looking to protect carburetors, injectors and fuel lines from ethanol-related issues and to preserve fuel quality during short-term storage without specialized service.
