Diesel Cetane Boost

Serious Performance Boost

Diesel engines operate best on fuel with cetane values of 50 or higher. Most diesel fuel sold in North America has a cetane value of 40-45. Diesel Cetane Boost delivers confidence in your diesel’s performance. Its concentrated formula uses unique chemistry to target and eliminate specific performance issues, maximizing diesel power.

Our customers call it money in their pocket. One bottle treats 100 to 160 gallons of diesel fuel boosting your cetane the right way. Thrust is gained at the wheels rather than smoke out the pipe.

Diesel Cetane BoostImproves Fuel Quality for Peak Performance

Fuel with a higher cetane number provides for a more complete burn, resulting in improved performance. By increasing cetane, Diesel Cetane Boost improves the ignition quality of diesel fuel, maximizing available power and improving starting. It also smooths idle and reduces smoke and emissions.
