Chevrolet T-Series, Owner'S Manual

At a minimum, the diesel fuel you use should meet
the latest version of ASTM specification D 975
(Grades No. 2-D or No. 1-D S15 commonly known
as Ultra Low Sulfur diesel) in the United States. In
addition, the Engine Manufacturers Association
(EMA) has identified properties of an improved
diesel fuel for better engine performance and
durability. Diesel fuels corresponding to the EMA
Recommended Guideline on Premium Diesel Fuel
(FQP-1A) could provide better starting, less noise,
and better vehicle performance. If there are
questions about the fuel you are using, contact your
fuel supplier.
Diesel fuel may foam when you fill your tank. This
can cause the automatic pump nozzle to shut
off, even though your tank is not full. If this
happens, just wait for the foaming to stop and
then continue to fill your tank. See
Filling the Tank
on page 185 .
{
CAUTION:
Heat coming from the engine may cause
the fuel to expand and force the fuel out
of your tank. If something ignites the fuel,
a fire could start and people could be
burned. To help avoid this, fill your fuel
tank only until the automatic nozzle shuts
off. Do not try to top it off.
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).
