Biodiesel Fuel Requirements - Jeep WRANGLER 2020 Owner's Manual

Biodiesel Fuel Requirements

A maximum blend of 5% biodiesel meeting
ASTM specification D975 is recommended for
use with your diesel engine. If frequent opera-
tion with Biodiesel blends that are between 6%
and 20% (B6–B20) is desired, the maintenance
schedule is subject to shorter intervals.
The oil and filter change along with fuel filter
replacement is subject to shorter intervals
when operating your engine on biodiesel
greater than 5%. Do not use biodiesel greater
than 20%.
For regular use of biodiesel blends between 6%
and 20% (B6–B20) it is important that you
understand and comply with these require-
ments. Refer to the "Maintenance Plan" in
"Scheduled Servicing" for further direction.
CAUTION!
Failure to comply with Oil Change
requirements for vehicles operating on
biodiesel blends between 6% and 20%
(B6–B20) will result in premature engine
wear. Such wear is not covered by the New
Vehicle Limited Warranty.
Biodiesel is a fuel produced from renewable
resources typically derived from animal fat,
rapeseed oil (Rapeseed Methyl Ester (RME)
base), or soybean oil (Soy Methyl Ester (SME or
SOME) base).
Biodiesel fuel has inherent limitations which
require that you understand and adhere to the
following requirements if you use blends of
Biodiesel between 6% and 20% (B6–B20).
There are no unique restrictions for the use
of B5.
CAUTION!
Use of blends greater than 20% is not
approved. Use of blends greater than 20%
can result in engine damage. Such damage is
not covered by the New Vehicle Limited
Warranty.
TECHNICAL SPECIFICATIONS
Biodiesel Fuel Properties — Low Ambient
Temperatures
Biodiesel fuel may gel or solidify at low ambient
temperatures, which may pose problems for
both storage and operation. Precautions can be
necessary at low ambient temperatures, such
as storing the fuel in a heated building or a
heated storage tank, or using cold temperature
additives.
Fuel Quality — Must Comply With ASTM
Standards
The quality of Biodiesel fuel may vary widely.
Only fuel produced by a BQ9000 supplier to the
following specifications may be blended to
meet Biodiesel blend B6 – B20 fuel meeting
ASTM specification D-7467:
Petrodiesel fuel meeting ASTM specification
