Supplemental Fuel Enhancers
Supplemental additives are not recommended because of a high risk of
injection system problems or engine damage.
There are many aftermarket products available today which are intended to be
added by the customer. They generally increase operating cost without
providing benefits. Included are a variety of independently marketed products
which claim to be:
앫
Cetane improvers
앫
Emission control additives
앫
Detergents
앫
Combustion improvers
앫
Smoke suppressants
앫
Cold weather flow improvers
Repair expenses resulting from malfunctions in the fuel system or with engine
components when fuel enhancers have been used are not covered under
warranty.
Some fuel additives can be used to provide temporary relief, but they do not
replace good fuel handling practices. These products can be used:
앫
Isopropyl Alcohol — Use 1/2 liter per 450 liters (1 pint per 125 gallons)
of fuel for winter freeze-up protection.
앫
Biocide — For treatment of microbe growth or “black slime.” Follow
manufacturer's instruction for treatment.
