9980 Self-Propelled Peanut Combine Fuel and Lubricants
Blends Above B20
AMADAS/John Deere engines can also
operate on biodiesel blends above B20 (up to
100% biodiesel) ONLY if the biodiesel meets
the EN 14214 specification (primarily available
in Europe). Engines operating on biodiesel
blends above B20 may not fully comply with all
applicable emissions regulations. Expect up
to a 12% reduction in power and an 18%
reduction in fuel economy when using 100%
biodiesel. John Deere approved fuel
conditioners containing detergent/dispersant
additives are required.
The following must also be considered when
using biodiesel blends above B20.
•
Possible coking and/or blocked injector
nozzles, resulting in power loss and engine
misfire if John Deere approved fuel
conditioners containing detergent/
dispersant additives are not used.
•
Possible crankcase oil dilution, requiring
more frequent oil changes.
•
Possible corrosion of fuel injection
equipment.
•
Possible lacquering and/ or seizure of
internal components.
• Possible formation of sludg
sediments.
•
Possible thermal oxidation of fuel at
elevated temperatures.
•
Possible elastomer seal and gasket
material degradation (primarily an issue
with older engines).
•
Possible compatibility issues with other
materials (including copper, lead, zinc, tin,
brass, and bronze) used in fuel system and
fuel handling equipment.
•
Possible reduction in water separator
efficiency.
•
Potential high acid levels within fuel
system.
•
Possible damage to paint if exposed to
biodiesel.
