BIODIESEL FUEL (DIESEL VEHICLES ONLY)
Biodiesel has unique qualities that should be considered before it is used in the Kubota D722 diesel engine. During
cold weather, plugged fuel lines, plugged fuel systems, hard starting, and other unknown failures can result from use
of this fuel.
Biodiesel is an excellent medium for microbial growth and contamination. Microbial contamination can cause corrosion
of the fuel system and prematurely plugged fuel filters.
See following NOTE.
NOTE:
Use of biodiesel may result in premature failure of fuel system components. Kubota has documented problems
such as plugged fuel filters and deteriorated fuel lines during testing of biodiesel.
Biodiesel can damage painted surfaces. Be sure to remove all spilled fuel immediately to help prevent damage to
painted surfaces.
If biodiesel will be used in the Kubota D722 engine, be sure that it meets the following requirements:
• The fuel blend should contain no more than 5% biodiesel by volume.
• The petroleum portion of the fuel blend must meet ASTM standard D975 and the biodiesel portion of the fuel
blend must meet ASTM standard D6751.
• For Europe, the fuel blend must meet the EN590 standard.
See following CAUTION.
CAUTION
• Never use any fuel that does not meet specifications or fuel in which the contents cannot be identified.
Using blends higher than 5% biodiesel content can affect engine life and cause deterioration of hoses,
tube lines, injectors, injector pump and seals.
• For more information on these fuel standards, please contact your nearest Kubota dealer.
If biodiesel is used, be sure to apply the following guidelines:
• Ensure the fuel tank is as full as possible at all times to prevent moisture from collecting.
• Ensure that the fuel tank cap is securely tightened to prevent water from entering the fuel tank.
• Drain all water from the fuel filter daily before operating vehicle.
