Canadian Fuels
Diesel-powered trucks are now equipped with emission control systems that
require the use of diesel fuel with low-sulfur (.05% 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 with low-sulfur fuel. Use of fuels with
higher-sulfur content will affect the function of the emission components
and may cause reduced performance, excessive smoke and unpleasant odor.
Cold Weather Operation
Follow the instructions listed previously under the heading "What Fuel to
Use ."
If you're driving in very cold temperatures and can't get a "winterized"
Number 2-D that has been adapted to cold weather or a Number 1-D, you
can use one gallon of kerosene for every two gallons of diesel fuel. Once
you add the kerosene, run your engine for several minutes so the fuels will
mix. Add kerosene only when the temperature fills below 0°F (-I 8"C),
because the fuel economy of kerosene isn't as good as that of diesel fuel.
I
NOTICE:
Never use home heating oil or gasoline in your diesel engine.
They can cause engine damage.
In cold weather, your fuel filter may become clogged (waxed). To unclog it,
warm the filter to between 32°F and 50°F (0°C to 10°C). You won't need
to replace it.
Water in Fuel
Sometimes, water can be pumped into your fuel tank along with your diesel
fuel. This can happen if a service station doesn't regularly inspect and clean
its fuel tanks, or if it gets contaminated fuel from its suppliers.
