New Holland Guidelines for Managing Biodiesel

New Holland Guidelines for Managing Biodiesel

For blends up to B5 (5% biodiesel)

  • Handle these blends no differently than quality regular diesel fuel.
  • Store for a maximum of six months.
  • Always refer to your owner’s manual and local OEM dealer for other guidelines specific to your engine model.
  • For older equipment (that precedes Tier II emission regulations or is out of production), the ONLY biodiesel blends approved are up to, and including, B5.

For blends greater than B5 through B20 (5% to 20% biodiesel)

  • Buy pre-blended biodiesel from a trusted supplier (BQ9000 certified if available) whose fuel meets ASTM D6751 standards.
  • Handle fuel carefully to assure water doesn’t enter the supply (biodiesel can attract water vapor from the air). Keep tanks as full as possible. Drain water from tank and engine-mounted fuel filters weekly.
  • Store for a maximum of three months — either in a tank or in a stored machine.
  • When initially converting to biodiesel, change fuel filters once or twice prior to the normal change interval. Biodiesel can loosen rust and particles from the inside of on-site fuel storage tanks, and that can clog filters.
  • Complete cleaning of a whole on-site handling system and storage tanks may be required. Use a fuel filter and water separator and make sure tanks, fuel lines and fittings are compatible with biodiesel.
  • Use a biocide during spring and summer months to prevent bacterial growth from clogging filters.
  • Once the temperature drops to 16°F (-8° C), your tank should be blended down to B5 or less for proper winter operation.
  • Always refer to your owner’s manual and local OEM dealer for other guidelines specific to your engine model.

For blends greater than B20 up to B100 (>20% to 100% biodiesel)

  • Follow all previously mentioned guidelines.
  • Check with your local OEM dealer for specific guidelines.
  • Obtain fuel certificates from the fuel supplier for each shipment as proof of ASTM D6751 compliance.
  • The storage tank must be protected against direct sunlight and frost.
  • When the temperature drops to 41°F (5° C), your tank should be blended down to B5 or less for proper winter operation.
  • Check hoses, connections and gaskets regularly.
  • Change all fuel filters, oil and oil filters when switching back to #2 diesel.
  • Monitor oil/engine deterioration through engine oil sampling.
  • Expect some engine power loss when higher percentages of biodiesel are used (4% to 7% when using B100).
