Description
Molecure™ PEA Complete Fuel System Cleaner — 12 oz
Bring back smooth power and confident throttle response with AGS Molecure™ PEA Complete Fuel System Cleaner. If your engine feels a bit lazy, hesitates from a stop, or idles rough, Molecure is the quick, one-bottle tune-up you can add during your next fill-up. Our high-strength polyether-amine (PEA) formula dissolves stubborn carbon and varnish where it builds up most—inside injectors, on intake valves/ports, and in the combustion chamber—so your engine can breathe, burn, and perform the way it should.
Purpose-built for modern gasoline engines—including port fuel injection (PFI), direct injection (GDI), turbocharged, and hybrids—Molecure helps smooth cold starts, supports accurate fuel-level sensor readings, and promotes cleaner, more efficient combustion over a full tank. It’s safe for oxygen sensors, catalytic converters, and capless fuel fillers.
Just pour one 12 oz bottle into a near-empty tank and fill with up to 20 gallons of gas. Use about every 3,000 miles (or sooner with heavy city/short-trip driving) to keep systems clean between services. Not for diesel engines.
