58 Fuel System
Note: 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:
•
Isopropyl Alcohol — Use 1 pint per
125 gallons (1/2 liter per 500 liters) of
fuel for winter freeze-up protection.
•
Biocide — For treatment of microbe
growth or “black slime.” Follow
manufacturer’s instruction for
treatment.
Prohibited Additives
The following additives are specifically
NOT allowed and must NOT be mixed in
with the vehicle diesel fuel:
Used Lubricating Oil:
Volvo Trucks North America, Inc. does
not recommend the use of any type of used
lubricating oil as an extender in the diesel
fuel. Used lubrication oil contains solids
and acids from the combustion process
that can severely corrode parts of the
injection system, resulting in reduced
power and higher maintenance cost over
time
Adding gasoline to diesel fuel will reduce
the cetane number and increase combustion
temperature. If a tank contains a diesel
fuel/gasoline mixture, it should be drained
and cleaned as soon as possible.
Gasoline:
WARNING
The addition of gasoline to diesel fuel
will create a serious fire hazard.
