Cetanium® cetane booster additive is a true cetane booster performance improver for diesel. It boosts your fuel's cetane up to 10 numbers, cleans injectors and pumps, and much more. We design it to provide an explosion of power and engine performance for off-road diesel racing engines and applications. Not only is Cetanium a diesel cetane booster additive, but it also improves horsepower and will increase your fuel mileage. Not to mention, our diesel fuel supplement replaces lost lubrication, removes sludge and deposits, and reduces smoking. Most other similar brands don't provide these additional benefits. For maximum benefit, use one 32-ounce can to treat 10 gallons of diesel fuel. You can also treat more than 10 gallons of fuel. For example, if you need to only boost cetane by up to 5 numbers, use one full can to treat 20 gallons of fuel.
