Even high-quality fuel can leave behind carbon deposits and corrosion from ethanol and water. Gumout Regane Complete Fuel System Cleaner conditions fuel against corrosion to help extend the life of key engine parts, while using P.E.A. (polyetheramine) to effectively remove deposits other products can’t, for maximized performance and fuel economy. P.E.A. is a nitrogen-based detergent stable enough to survive the harsh conditions of a combustion chamber. It is the most potent detergent available for cleaning carbon deposits in fuel systems and the only cleaning agent that has been proven to clean the combustion chamber, piston tops and cylinder heads. P.E.A. also cleans ports, valves and GDI and port injectors and keeps them clean for up to 3,000 miles
