BIODIESEL
Diesel fuel containing no more than 5% biodiesel may be used. To help
achieve acceptable engine performance and durability, it is important to
only use biodiesel of good quality in your diesel engine. At a minimum,
the biodiesel should comply with ASTM D6751 or an equivalent
specification.
Use of biodiesel in concentrations greater than 5% may cause damage to
your vehicles fuel system components such as fuel tank, fuel lines, fuel
pump, fuel sender and fuel injectors. Concentrations greater than 5% can
also cause fuel filter restrictions that may result in a lack of power and
or fuel pump and fuel injector failure.
Look for a label on the fuel pump to confirm the amount of biodiesel
contained in a diesel fuel. Biodiesel content is often indicated with the
letter “B” followed by the percent of biodiesel in the fuel. For example,
B5 indicates a fuel containing 5% biodiesel. Ask the service station
attendant to confirm the biodiesel content of a diesel fuel if you do not
see a label on the fuel pump.
Biodiesel should not be stored in the fuel tank for more than three
months. If your vehicle will be parked or stored for more than three
months, then your vehicle should be drained and filled with a diesel fuel
not containing biodiesel.
During cold weather, if you have problems operating on biodiesel, you
may need to use a diesel fuel with lower biodiesel content, try another
brand, or discontinue the use of biodiesel.
Biodiesel use may affect the recommended oil change intervals. Refer to
the
Special Operating Conditions
section in the
schedule
maintenance guide
for more information about oil change intervals and
other maintenance when operating on biodiesel.
Biodiesel fuel is a product that has been converted from renewable fuel
sources, including vegetable oil, animal fat and cooking oil. Raw or
refined vegetable oil, animal fat, cooking oil or recycled greases should
not be used.
Do not use home heating oil, agricultural fuel or any diesel fuel
not intended for highway use. Damage to the fuel injection
system, engine and exhaust catalyst can occur if an improper fuel
is used. Do not add gasoline, gasohol or alcohol to diesel fuel.
This practice creates a serious fire hazard and engine
performance problems.
