Gumout Fuel Additives

Gumout makes fuel system cleaners and additives that remove carbon deposits, clean fuel injectors and carburetors, and protect engines against ethanol-related corrosion. The products work on both modern direct-injection engines and older carbureted powersports machines.

Gumout traces its roots to a wartime solvent developed to remove gum and varnish from fuel systems. Today riders use Gumout to keep small engines, motorcycles, and ATVs running clean and starting reliably after storage.
