BioDiesel Fuel
BioDiesel fuel is comprised of mono-alkyl esters of long
chain fatty acids derived from vegetable oils or animal
fats. BioDiesel blends are BioDiesel mixed with petroleum
diesel fuel on a volume basis.
Before using fuel containing BioDiesel, review the
BioDiesel Use Requirements and Recommendations in
this Operator’s Manual.
Environmental laws and regulations can encourage or
prohibit the use of biofuels. Operators should consult
with appropriate governmental authorities prior to using
biofuels.
All John Deere Engines with Exhaust Filter
(Released 2011 and After)
While 5% blends (B5) are preferred, BioDiesel
concentrations up to a 20% blend (B20) in petroleum
diesel fuel can be used. BioDiesel blends up to B20
can be used ONLY if the BioDiesel (100% BioDiesel or
B100) meets ASTM D6751, EN 14214, or equivalent
specification. Expect a 2% reduction in power and a 3%
reduction in fuel economy when using B20.
BioDiesel concentrations above B20 can harm the
engine’s emission control systems and should not be
used. Risks include, but are not limited to, more frequent
stationary regeneration, soot accumulation, and increased
intervals for ash removal.
John Deere approved fuel conditioners, which contain
detergent and dispersant additives, are required when
using BioDiesel blends from B10—B20, and are
recommended when using lower BioDiesel blends.
All John Deere Engines Excluding Exhaust Filter
(Primarily Released Prior to 2012)
While 5% blends (B5) are preferred, BioDiesel
concentrations up to a 20% blend (B20) in petroleum
diesel fuel can be used. BioDiesel blends up to B20
can be used ONLY if the BioDiesel (100% BioDiesel or
B100) meets ASTM D6751, EN 14214, or equivalent
specification. Expect a 2% reduction in power and a 3%
reduction in fuel economy when using B20.
These John Deere engines can operate on BioDiesel
blends above B20 (up to 100% BioDiesel). Operate at
levels above B20 ONLY if the BioDiesel is permitted
by law and meets the EN 14214 specification (primarily
available in Europe). Engines operating on BioDiesel
blends above B20 might not fully comply with or be
permitted by 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, which contain
detergent and dispersant additives, are required when
using BioDiesel blends from B10—B20, and are
recommended when using lower BioDiesel blends.
BioDiesel Use Requirements and Recommendations
The petroleum diesel portion of all BioDiesel blends must
meet the requirements of ASTM D975 (US) or EN 590
(EU) commercial standard.
BioDiesel users in the U.S. are strongly encouraged to
purchase BioDiesel blends from a BQ-9000 Certified
Marketer and sourced from a BQ-9000 Accredited
Producer (as certified by the National BioDiesel Board).
Certified Marketers and Accredited Producers can be
found at the following website: http://www.bq9000.org.
BioDiesel contains residual ash. Ash levels exceeding the
maximums allowed in either ASTM D6751 or EN14214
can result in more rapid ash loading and require more
frequent cleaning of the Exhaust Filter (if present).
The fuel filter can require more frequent replacement,
when using BioDiesel fuel, particularly if switching from
diesel. Check engine oil level daily prior to starting engine.
A rising oil level can indicate fuel dilution of the engine oil.
BioDiesel blends up to B20 must be used within 90 days
of the date of BioDiesel manufacture. BioDiesel blends
above B20 must be used within 45 days from the date
of BioDiesel manufacture.
When using BioDiesel blends up to B20, the following
must be considered:
•
Cold-weather flow degradation
•
Stability and storage issues (moisture absorption,
microbial growth)
•
Possible filter restriction and plugging (usually a problem
when first switching to BioDiesel on used engines)
•
Possible fuel leakage through seals and hoses
(primarily an issue with older engines)
•
Possible reduction of service life of engine components
Request a certificate of analysis from your fuel distributor
to ensure that the fuel is compliant with the specifications
provided in this Operator’s Manual.
Consult your John Deere dealer for approved fuel
conditioners to improve storage and performance with
BioDiesel fuels.
The following must also be considered if using BioDiesel
blends above B20:
•
Possible coking or blocked injector nozzles, resulting in
power loss and engine misfire if John Deere approved
fuel conditioners are not used
•
Possible crankcase oil dilution (requiring more frequent
oil changes)
•
Possible lacquering or seizure of internal components
•
Possible formation of sludge and sediments
•
Possible thermal oxidation of fuel at elevated
temperatures
•
Possible compatibility issues with other materials
(including copper, lead, zinc, tin, brass, and bronze)
used in fuel handling equipment
