Fuel Contamination—Generally, fuel
contamination occurs as the result of
improper fuel handling. The most com-
mon types of contamination are water,
dirt, and microbial growth ("black slime").
The formation of varnishes and gums
resulting from poor stability or extended
storage ("stale fuel") also affects fuel
quality. The best treatment for contami-
nation is prevention by maintaining a
clean storage system and choosing a
reputable fuel supplier.
Supplemental additives are not
recommended due to potential
injector system or engine damage.
Our experience has been that such
additives increase operating costs with-
out providing benefit.
The use of supplemental fuel addi-
tives does not necessarily void the
engine warranty. However, repair
expenses which result from fuel
system or engine component mal-
functions or damage attributed to
their use will not be covered. These
products should be accompanied by
performance data supporting their merit.
It is not the policy of Detroit Diesel
Corporation to test, evaluate, approve,
or endorse such products.
Prohibited Additives
The following Fuel Additives are
NOT allowed and MUST NOT be
mixed with diesel fuel:
Used Lubricating Oil—Detroit
Diesel specifically prohibits the use of
drained lubricating oil in diesel fuel.
Used lubricating oil contains combus-
tion acids and particulate materials
which can severely erode fuel injector
components, resulting in loss of
power and increased exhaust emis-
sions. In addition, the use of drained
lubricating oil will increase mainte-
nance requirements due to filter plug-
ging and combustion deposits.
Gasoline—
CAUTION:
The addition of gasoline to diesel
fuel will create a serious fire hazard.
