Description
Gumout 2X Fuel Injector Cleaner High Mileage is a specialized 6oz fuel system treatment designed specifically for vehicles with over 75,000 miles. This advanced formula addresses the unique needs of high-mileage engines by providing enhanced cleaning power that removes stubborn deposits, varnish, and carbon buildup that accumulate over years of driving. The concentrated solution treats up to 21 gallons of gasoline, delivering professional-grade cleaning results that restore lost performance and improve fuel economy. The 2X formula provides double the cleaning power of standard fuel treatments, making it particularly effective for neglected fuel systems or engines experiencing performance issues. Key benefits include improved acceleration, smoother idle, reduced emissions, and enhanced fuel efficiency. The treatment works by dissolving deposits in fuel injectors, intake valves, combustion chambers, and throughout the fuel system while lubricating critical components. Regular use helps prevent future deposit formation and maintains optimal fuel system cleanliness. This high-mileage specific formula also contains seal conditioners that help maintain fuel system integrity in older vehicles. Compatible with all gasoline engines and safe for use with catalytic converters, oxygen sensors, and other emissions control equipment.
Suggested Use
Add entire 6oz bottle to nearly empty fuel tank, then fill with up to 21 gallons of gasoline. Drive normally to allow treatment to circulate through fuel system. Use every 3,000 miles or with every oil change for high-mileage vehicles. For severely clogged systems, use two consecutive treatments.
