Diesel Cetane Booster
Fuel System
Increases diesel fuel cetane rating to improve ignition characteristics, combustion quality, and overall engine performance.
Diesel Cetane Booster raises the cetane number of diesel fuel, which measures how easily the fuel ignites under compression. Higher cetane improves combustion quality, reduces rough idle and starting difficulty, and can improve fuel economy and emissions. It's particularly useful in colder climates where winter diesel blends sometimes have lower cetane ratings.
