Product description

Gumout One-N-Done Complete Fuel System Cleaner is specially formulated with advanced P.E.A. technology for unsurpassed cleaning strength. It is designed to be a once-per-year treatment that improves performance & fuel economy and helps reduce emissions in just one use. Compare that to using products that require repeated usage every fill up or 3000 miles and you will find that One-N-Done offers the most complete fuel system cleaning at the best value. Polyether amine, or P.E.A. for short, is the most advanced cleaning agent available. It is strong enough to cut through thick carbon deposits even in the intense heat found in the combustion chamber. Directions: Add entire bottle to nearly empty gasoline tank at time. Refill tank with up to 25 gallons of gasoline. Do not refill tank until near empty. Use every year or 10,000 to 15,000 miles.
