What Fuel to Use in Canada
Canadian fuels are blended for seasonal changes. Diesel
Type “A” fuel is blended for better cold weather starting
(below 0
_F or
-
18
_C); however, you may notice some
power and fuel economy loss. If Type “A” fuel is used
in warmer temperatures, stalling and hard starting may
occur. Diesel Type “B” fuel is blended for temperatures
above 0
_F (
-
18
_C). The emission control system
requires 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 only 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.
At a minimum, the diesel fuel you use should meet
specifications CAN/CGSB
-
3.517
-
2000 (Low Sulfur
Diesel) in Canada. In addition, the Engine
Manufacturers Association (EMA) has identified
properties of an improved diesel fuel for better engine
performance and durability (FQP
-
1A). Diesel fuels
corresponding to the EMA description could provide
better starting, less noise and better vehicle
performance. If there are questions about the fuel you
are using, contact your fuel supplier.
Very Cold Weather Operation
Follow the instructions listed previously under the
heading “What Fuel to Use.”
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, move the vehicle to a warm
garage area and warm the filter to between 32
_F and
50
_F (0_C to 10_C). You won’t need to replace it.
Additional information on the fuel filter follows.
