Mercury Quickleen Engine & Fuel System Cleaner, 12 oz 8M0047921

Mercury Quickleen Engine & Fuel System Cleaner, 12 oz 8M0047921 is a genuine Mercury/Quicksilver OEM fuel additive designed to remove harmful carbon deposits and help restore engine performance. Safe for use in all 2-cycle and 4-cycle carbureted and fuel-injected gasoline engines, Quickleen helps keep fuel systems and combustion chambers clean for smoother, more efficient operation.

Compatible with the following:

• Mercury and Mariner outboards
• MerCruiser gasoline engines
• All 2-cycle and 4-cycle carbureted and fuel-injected gasoline engines
• Safe for catalyzed engines

Quickleen quickly removes carbon deposits from carburetors, fuel injectors, intake valves, spark plugs, piston crowns, and cylinder heads. Regular use helps reduce engine knocking, minimize the risk of piston seize-up, and extend spark plug life while promoting cleaner combustion and improved engine efficiency.

This concentrated treatment can be added at every fuel fill-up, with one ounce treating up to five gallons of gasoline. It's an excellent choice for maintaining peak engine performance and reducing the carbon buildup that naturally occurs over time, especially in engines operated under heavy loads or frequent idling.

Quicksilver is Mercury Marine's official parts and accessories brand, offering the same OEM quality and fit as Mercury-branded components.
