Driving and Operating
What Fuel to Use in
Canada and Mexico
Use only diesel fuel with ultra low
sulfur content (15 ppm maximum).
What Fuel to Use in Canada
Use diesel fuel that meets CAN/
CGSB-3.517 specification in
Canada. Contact a fuel supplier for
questions about fuel.
{
Caution
Use of diesel fuel other than Ultra
Low Sulfur Diesel (15 ppm sulfur
maximum) will cause damage to
the exhaust after-treatment
system. This damage would not
be covered by the vehicle
warranty. Do not use marine,
locomotive, or boiler distillate fuel
since it may contain higher sulfur
levels.
Diesel Fuel Types
Fuels are blended for seasonal
changes. Diesel Type A fuel is
blended to ensure vehicles operate
in extreme cold temperatures. This
fuel, however, may cause some
power and fuel economy losses.
Diesel Type B fuel is blended for
higher temperatures experienced
during most of the year. Avoid using
Diesel Type A fuel in warm or hot
climates. Doing so can result in
stalling, poor starting when the
engine is hot, and damage to the
fuel injection system.
Premium Diesel Fuel
If available, premium diesel fuel
(FQP-1A) corresponding to the
Engine Manufacturers Association
(EMA) Recommended Guideline
could provide better starting and
vehicle performance with less noise.
Biodiesel
Biodiesel is a renewable fuel
produced from vegetable oils or
animal fats that have been
chemically modified for normal
engine performance.
{
Caution
Do not use home-made biodiesel
or home test kits because the
quality cannot be verified by
approved scientific methods. Do
not use raw vegetable oil or other
unmodified bio-oils, fats,
or blends of vegetable oil with
diesel. They could damage the
fuel system and engine, and
damages would not be covered
by the vehicle warranty.
Biodiesel blends
Biodiesel blends that meet the CAN/
CGSB-3.522 specifications up to
20% (B20) can be used. Avoid the
use of biodiesel blends above 20%,
as they may damage the engine
