Cataclean Fuel System Cleaner 16oz

Cataclean Fuel System Cleaner 16oz by Mr. Gasket is a professional-grade fuel additive engineered to restore combustion efficiency and engine performance in gasoline-powered vehicles. Fuel injectors, intake valves, and combustion chambers accumulate carbon deposits over time, leading to rough idling, hesitation, and reduced fuel economy. This 16-ounce bottle treats a full fuel tank, making it an economical maintenance solution for drivers seeking to eliminate varnish buildup and restore factory-spec engine operation without costly mechanical intervention.

The formulation works by dispersing and suspending carbon, gum, and lacquer deposits that form on fuel system components, allowing them to be purged through normal combustion. Mr. Gasket's Cataclean technology targets multiple failure points—fuel injector tips, intake valve seats, and catalytic converter surfaces—where deposit accumulation most severely impacts performance and emissions. The cleaner dissolves stubborn residues while protecting fuel system metals and seals, ensuring compatibility with modern fuel injection systems and oxygen sensor technology. A single 16-ounce treatment provides measurable improvements in throttle response, acceleration, and cold-start behavior within one to two full fuel cycles.

Fleet operators, daily commuters, and performance enthusiasts benefit most from preventive fuel system maintenance, particularly vehicles with high-mileage engines or those running on lower-quality fuel sources. The product suits any gasoline engine—from standard sedans and light trucks to modified powerplants—and requires no disassembly or professional installation; simply pour the entire bottle into the fuel tank before refueling. Recommended for use every 3,000 to 5,000 miles or whenever engine hesitation, poor fuel economy, or rough idle becomes apparent, this additive serves as a cost-effective alternative to fuel injector cleaning services and complete fuel system flushes.
