Fuel System 55
Fuel Additives
General
Fuel additives are generally not recom-
mended or needed for fuels listed earlier.
Cetane improvers can be used as necessary.
Biocides may be needed to eliminate mi-
croorganism growth in storage tanks. In
cold conditions, treatment for water in the
vehicle tanks may also be necessary.
Consult your fuel supplier about the use of
additives to prevent incompatibility among
additives already in the fuel and the addi-
tives to be used.
Supplemental Fuel Enhancers
CAUTION
Supplemental additives are not recom-
mended because of a high risk of
injection system problems or engine
damage.

able today which are intended to be added
