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.

I like the Cetane Boost it gives me noticeable extra power when it comes to towing. My Kubota tractor would always bog down in heavy snow and now it walks right through it. I highly recommend this product.

Great Product

I am using this product in 2 older diesel engines, a 1984 Toyota Landcruiser 3B diesel with 520,000 km and a 1992 Dodge with a 5.9 ltr Cummins with 230,000 km. Mixing for a 7 point increase has given the Toyota a “seat of the pants” felt increase in power with overall fuel mileage up 1 mpg. The Dodge always had good power but with a 7 point increase mix I have gained a gear on hills and overall mileage is up 1.5 mpg. all while moving 5.5 tons of truck and load. Overall I am very satisfied with the product.
