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.
It is acceptable to use diesel fuel containing up to
5% biodiesel (B5), but the final blended fuel must meet
the same specification, CAN/CGSB—3.517–2000
(Low Sulfur Diesel) in Canada, as other fuels used in
your vehicle, and the biodiesel used for making this fuel
must meet the ASTM D6751–02 specification.
Biodiesel is produced from vegetable oils or animal fat
that have been chemically modified to reduce the
possibility of damage to your fuel system and engine.
Higher concentration (i.e., greater than B5)
biodiesel-containing fuels or the use of unmodified
bio-oils blended into diesel fuel at any concentration is
not recommended and could damage your fuel
system and engine. Such damage would not be covered
by your warranty. If there are questions about the
biodiesel-containing fuels you are using, contact your
fuel supplier.
