Diesel Kleen® +Cetane Boost® is the premier “performance” product on the market. Diesel Kleen® is loaded with cetane， detergency and lubricity additives to keep your diesel engine running at peak performance.

If you are looking for an antigel， Diesel Fuel Supplement® +Cetane Boost® is the product you should be using. Like Diesel Kleen®， Diesel Fuel Supplement® contains a cetane and detergency package. However， it is not as concentrated as Diesel Kleen® to allow for the superior antigel in Diesel Fuel Supplement®.
