Top Tier Fuel

GM recommends the use of TOP TIER Diesel
Fuel to keep the engine clean, reduce engine
deposits, and maintain optimal vehicle
performance. Look for the TOP TIER Logo or
see www.toptiergas.com for a list of TOP
TIER Diesel Fuel marketers and applicable
countries.

Fuel Additives

TOP TIER Detergent Diesel is highly
recommended for use with your vehicle.
If your area does not have TOP TIER
Detergent Diesel, GM recommends the use
of ACDelco Diesel Fuel Conditioner. This will
help maintain optimal engine performance.
GM does not recommend other aftermarket
diesel additives.
Driving and Operating
If low-quality diesel is used for refueling,
GM recommends adding ACDelco Fuel
System Treatment Plus-Diesel to help clean
engine deposits. This is available at your GM
dealer.

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.
Use Ultra Low Sulfur Fuel, which refers to
fuel with less than 15 ppm sulfur.
Do not use a diesel blend containing more
than 20% 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.
