Cold weather operability (Preventing fuel from gelling/crystalizing in the cold



Significantly reducing the output of emissions leading to cleaner air



Improving lubricity (internal engine lubrication) to save engine wear



Microbial Growth control (killing microbes & preventing bacteria from reforming)



Water dispersment (breaks down water to prevent harmful water effects)



Stabilizers to increase shelf life (without this, fuel begins to deteriorate after 21 days)



Fuel detergents (cleans engines, fuel systems, injectors & fuel lines)



Cetane enhancement (higher cetane number provides better combustion, more energy output & less emissions)



Combustion modification (improved performance, better fuel quality)
