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.
Fuel quality
It should not be necessary to add any aftermarket additives to your fuel
tank if you use a properly formulated diesel fuel that meets the ASTM D
975 industry specification. Aftermarket additives can damage the injector
system or engine. Repairs to correct the effects of using an aftermarket
product in your fuel may not be covered by your warranty.
Do not blend used engine oil with diesel fuel under any
circumstances.
Blending used oil with the fuel will significantly increase
your vehicle’s exhaust emissions and reduce engine life due to increased
internal wear.
Many of the world’s automakers approved the World-wide Fuel Charter
that recommends diesel fuel specifications to provide improved
performance and emission control system protection for your vehicle.
Diesel fuel that meets the World-wide Fuel Charter should be used when
available. Ask your fuel supplier about fuel that meets the World-wide
Fuel Charter.
