Fuel Additives

GM recommends the use of

adding ACDelco Fuel System
Treatment Plus-Diesel to the
vehicle s fuel tank. ACDelco Fuel
System Treatment Plus-Diesel can
help clean engine deposits and is
available only at your GM
dealership.

Fuel for Diesel Engines

The selection of a high-quality fuel
is important for maintaining optimum
vehicle performance. Diesel fuel
should meet or exceed the minimum
requirements in the most current
versions of the local fuel standards.
Do not use fuel with more than 15
ppm sulfur. If available, use of diesel
fuel with less sulfur is highly
recommended for better emissions.
In countries where 15 ppm or lower
sulfur is not available, do not use
diesel fuel with sulfur great than 50
ppm. In these countries only, the
vehicle is already designed to
accommodate this level of sulfur.
Do not use a diesel blend containing
more than 10% biodiesel by volume.
Caution
Use of fuel that does not comply
with the required technical
standards can lead to engine
power loss, increased wear,
or engine damage and may void
your warranty.
Some improper fuels are:
Diesel fuel with the addition
of gasoline.

Driving and Operating
Caution (Continued)

raw vegetable oil or animal
fat, in any form, including

biodiesel.
Marine diesel fuel and
fuel oils.
Diesel-water emulsions,
such as Aquazole.
Aftermarket diesel fuel
additives, which contain
alcohols, organo-metallic
additives, or water
