C 3500 HD Truck 2WD V8-6.5L DSL Turbo VIN F (2001)
Fuel: Description and Operation
Some states and provinces have restrictions on the purchase of diesel fuel for light duty vehicles and require you to buy permits or pay special taxes.
Some of these restrictions apply to residents, and others apply to both residents and visitors. These restrictions can change. To learn the current
restrictions in any state or province, contact your auto club, the police or other officials.
What Fuel to Use In the United States
In the United States, for best results use Number 2-D diesel fuel year-round (above and below freezing conditions) as oil companies blend Number
2-D fuel to address climate differences. Number 1-D diesel fuel may be used in very cold temperatures (when the temperature stays below -18°C or 0°
F). However, the fuel will produce a power and fuel economy loss. The use of Number 1-D diesel fuel in warm or hot climates may result in stalling,
poor starting when the engine is hot and may damage the fuel injection system.
Diesel fuel may foam when filling the tank. This can cause the automatic pump nozzle to shut off, even though the tank is not full. If this happens, wait
for the foaming to stop and then continue to fill the tank.
What Fuel to Use In Canada
Canadian fuels are blended for seasonal changes. Diesel Type A fuel is blended for better cold weather starting when it stays below 18°C or (0°F).
However, the fuel will produce a power and fuel economy loss. The use of Type A diesel fuel in warmer climates may result in stalling, poor starting.
Diesel Type B fuel is blended for temperatures above 18°C (0°F). The emission control system requires the use of diesel fuel with low sulfur (0.05
percent by weight) content. Both low and higher sulfur fuels will be available in Canada. Only low sulfur diesel fuels are available in the United
States. It is important that diesel-powered trucks are refueled only with low sulfur fuel. Use of fuels with higher-sulfur content will affect the function
of the emission components and may caused reduced performance, excessive smoke and unpleasant odor.
Very Cold Weather Operation
If the vehicle is driven in very cold temperatures and can not get a winterized Number 2-D that has been adapted to cold weather or a Number 1-D,
use one gallon of kerosene for every two gallons of diesel fuel. Once you add kerosene, run the engine for several minutes to mix the fuels. Only add
kerosene when the temperature falls below -18°C (0°F), because the fuel economy and lubricating qualities of kerosene is not as good as that of diesel
fuel.
In cold weather, the fuel filter may become clogged (waxed). To unclog the filter, move the vehicle to a warm garage area and warm the filter to a
temperature between 0 -10°C (32 -50°F). Replacing the filter is not necessary.
Water In Fuel
Sometimes, water can be pumped into the fuel tank along with diesel fuel. This can happen if the service station does not regularly inspect and clean
their fuel tanks, or the fuel gets contaminated for the service stations suppliers.
If water is pumped into the fuel tank, a water in fuel light will illuminate. If the water in fuel light illuminates, the excess water must be drained from
the fuel system on the vehicle.
The water in fuel light also should illuminate briefly when the engine is started as a check. If the light does not illuminate, the problem should be fixed
to identify a water in fuel condition correctly.
