DurAlt Fuel Conditioner can treat both gasoline and diesel engines, carbureted or fuel injected.  It gives your engine what it really needs -- allowing it to function as designed at maximum efficiency while cleaning and lubricating the fuel injectors and fuel pump.  It is ideal for new vehicles as well as older vehicles that require leaded fuel.  DurAlt replaces the benefits of lead in gasoline without causing harmful emissions.   It can be used to pass smog tests, and totally neutralizes the harmful effects of low sulfur diesel fuel by lubricating engine parts and preventing carbon deposits.

Whether you own a motorcycle, car, truck, SUV, RV bus, generator, boat, lawn equipment or a fleet of vehicles, DurAlt is your answer for better performance, lower emissions and savings!

Our 2oz Bottle is perfect to treat motorcycles or small engines like generators, lawn mowers and snow blowers.
DurAlt keeps fuel fresh for over a  year!
