Bio-Diesel Fuel
Bio-diesel fuels may be used ONLY if the bio-diesel fuel properties meet the latest edition of
ASTM PS121, DIN 51606 or equivalent specification.
It has been found that bio-diesel fuels may improve lubricity in concentrations up to a 5% blend
in petroleum diesel fuel.
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 the oil becomes diluted with fuel, shorten oil change
intervals accordingly.
IMPORTANT: Raw pressed vegetable oils are NOT acceptable for use for fuel in any
concentration.
These oils do not burn completely, and will cause engine failure by leaving deposits on
injectors and in the combustion chamber.
Handling and Storing Bio-Diesel Fuel
WARNING
!
Handle fuel carefully. Do not fill the fuel tank when engine is running.
DO NOT smoke while you fill the fuel tank or service the fuel system.
Fill the fuel tank at the end of each day's operation to prevent water condensation and freezing
during cold weather.
Keep all storage tanks as full as practicable to minimize condensation.
Ensure that all fuel tank caps and covers are installed properly to prevent moisture from
entering.
Monitor water content of the fuel regularly.
Fuel filter may require more frequent replacement due to premature plugging.
Check engine oil level daily prior to starting engine. A rising oil level may indicate fuel dilution
of the engine oil.
When fuel is stored for an extended period or if there is a slow turnover of fuel, add a fuel
conditioner to stabilize the fuel and prevent water condensation. Contact your fuel supplier for
recommendations.
