MAINTENANCE, LUBRICATION AND SERVICE
FUEL SYSTEM
DANGER
A diesel engine will operate on any fuel
which enters the cylinder, whether it is
from the injectors or from the air intake
system. Therefore, if any solvent is used
to clean out the air cleaner element, the
engine may over speed during start-up.
Engine damage, severe personal injury or
death from burns or explosion may occur.
DANGER
DO NOT mix gasoline or alcohol with
diesel oil fuel. This mixture can cause an
explosion and result in severe personal
injury or death.
DANGER
DO NOT remove the fuel tank cap near an
open flame. Diesel fumes are combustible
and can cause an explosion or fire
resulting in severe personal injury or
death.
WARNING
If a fuel leak is detected, stop the engine
immediately. The vapors from hot fuel are
highly flammable which may result in a
fire.
WARNING
DO NOT store fuel containers in the
vehicle. They may leak, explode and
cause or feed a fire. Empty or full, they
present a hazard that may lead to burns in
the event of a fire.
Diesel Fuel Specification
CAUTION
Diesel engines for 2007 and later model
year vehicles are designed to operate only
with Ultra Low Sulfur Diesel (ULSD) fuel.
Use of fuel other than ULSD will reduce
the efficiency and durability of the engine,
permanently damage the advanced
emission control systems, reduce fuel
economy and possibly prevent the engine
from running at all. Manufacturers
warranties are likely to be rendered void
by usage of improper or incorrect fuel,
and usage of fuels other than ULSD fuel in
diesel-powered vehicles is illegal and
punishable with civil penalties. Use of fuel
additives to compensate for the lower
sulfur content is NOT recommended.
Quality
The proper selection of fuel is essential
for good economy, performance and
engine life. No. 2D ULSD should be
used when climatic conditions permit.
No. 1D ULSD can be used during cold
weather conditions. Blends of No. 1D
and No. 2D ULSD fuels can be used to
suit various climatic conditions.
NOTE
The use of lighter fuels (grade No. 1-D)
can reduce fuel economy
Fuel Sulfur Content
Fuel sold for use in diesel-powered
engines for 2007 and later model year
vehicles may only contain a maximum
sulfur content of 0.0015% by weight.
This was done to reduce particle
emissions in the exhaust
NOTE
The use of ultra-low sulfur diesel fuel does
not permit extension of engine oil change
intervals or oil filter changes.
Cetane Number
Direct injected diesel engines require a
minimum cetane number of 43 under
normal starting conditions. Fuel with a
higher cetane value may be required for
high-altitude or cold-weather operation.
Filtration
Fuel should be clean and free of
contamination. Clean fuels should have
no more than 0.05% of sediment and
water.
