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.

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.

Sioux Falls store note: “We call it FREE Money. The Cetane Boost corrects the fuel for the engine. Search what your average diesel fuel cetane number is in the area then add the boost as recommended to bring it to a 50 which is what the engine demands for optimum combustion. Well they explain the rest below pretty well below but this product goes a LONG way so a 16 ounce bottle or the 1/2 gallon gives you a boost in power which coverts to measured MPG. Try and see for yourself! Especially when you are hauling loads, driving against wind or climbing hills (or using #1 diesel, etc)..”
