Bio-Diesel Fuel
Consult your local fuel distributor for properties of the
bio-diesel fuel available in your area.
Bio-diesel fuels may be used ONLY if the bio-diesel
fuel properties meet the latest edition of ASTM D6751,
EN 14214, or equivalent specification.
It is recommended to purchase bio-diesel fuel blended
with B100 from a BQ-9000 Accredited Producer or a
BQ-9000 Certified Marketer as recommended by the
National Bio-diesel Board.
The maximum allowable bio-diesel concentration is a
5% blend (also known as B5) in petroleum diesel fuel.
It has been found that bio-diesel fuels may improve
lubricity in concentrations up to this 5% blend.
When using a blend of bio-diesel fuel, the engine oil
level must be checked daily when the air temperature
is –10°C (14°F) or lower. If oil becomes diluted with
fuel, shorten oil change intervals accordingly.
IMPORTANT: Raw pressed vegetable oils are NOT
acceptable for use as fuel in any
concentration in John Deere
engines.
These oils do not burn completely,
and will cause engine failure by
leaving deposits on injectors and in
the combustion chamber.
A major environmental benefit of bio-diesel fuel is its
ability to biodegrade. This makes proper storage and
handling of bio-diesel fuel especially important. Areas
of concern include:
• Quality of new fuel
• Water content of the fuel
• Problems due to aging of the fuel
Potential problems resulting from deficiencies in the
above areas when using bio-diesel fuel in
concentrations above 5% may lead to the following
symptoms:
• Power loss and deterioration of performance
• Fuel leakage
• Corrosion of fuel injection equipment
• Coked and/or blocked injector nozzles, resulting in
engine misfire
• Filter plugging
• Lacquering and/or seizure of internal components
• Sludge and sediments
• Reduced service life of engine components
Consult your fuel supplier for additives to improve
storage and performance of bio-diesel fuels.
