Octane boosters are added during the refining process to improve the octane rating of gasoline.
One of the primary purposes of octane boosters is to prevent engine knocking or “pre-detonation.”
Octane boosters are used to formulate premium or performance-grade fuels (like 95 or 98 octane gasoline) for sports cars and high-performance vehicles.
Cetane improvers are used to increase the cetane number of diesel fuels, improving ignition quality.
By improving the ignition quality of diesel fuel, cetane improvers help lower harmful emissions such as nitrogen oxides (NOx), carbon monoxide (CO), and unburned hydrocarbons.
In colder climates, diesel fuels with lower cetane numbers struggle to ignite, leading to starting difficulties.
