Using low sulfur (16-500 ppm) or high sulfur (greater than
500 ppm) diesel fuel in a diesel engine designed to use only
Ultra Low Sulfur Diesel fuel increases the likelihood of engine oil
dilution with fuel which may lead to major engine damage.
Using low sulfur (16-500 ppm) or high sulfur (greater than
500 ppm) diesel fuel in a diesel engine designed to use only
Ultra Low Sulfur Diesel fuel will cause certain emission components to
malfunction which may also cause the Service Engine Soon (
light to illuminate indicating an emissions-related concern.
Do not mix diesel fuel with gasoline, gasohol or alcohol. This
could cause an explosion resulting in personal injury.
Do not use starting fluid such as ether or gasoline. Such fluids
can cause immediate explosive damage to the engine and
possible personal injury.
Fuel quality
It should not be necessary to add any aftermarket additives to your fuel
tank if you use a properly formulated diesel fuel that meets ASTM D 975
specification. Aftermarket additives can damage the injector system or
engine. Repairs to correct the effects of using an aftermarket product in
your fuel may not be covered by your warranty.
Do not blend used engine oil with diesel fuel under any
circumstances. Blending used oil with the fuel will significantly increase
your vehicle's exhaust emissions and reduce engine life due to increased
internal wear.
Many of the world's automakers approved the World-wide Fuel Charter
that recommends diesel fuel specifications to provide improved
performance and emission control system protection for your vehicle.
Diesel fuel that meet the World-wide Fuel Charter should be used when
available. Ask your fuel supplier about fuel that meet the World-Wide
Fuel Charter.
