Gumout® has been the scientific leader in vehicle maintenance and performance since 1945. It all began when president Roosevelt promised prime minister Churchill wartime equipment under the Lend Lease program in 1941. The United States transported tanks, planes, cars, and trucks to England by ship. During the journey, the carburetors were gummed up by gasoline vapors. The US enlisted the help of a small company in Western Pennsylvania that provided a solvent to remove the vapor varnish from the equipment. The solvent was called Gumout®, and it did exactly that. Today, the company offers a full line of fuel additives, including fuel system cleaners and fuel injector cleaners.
