Biodiesel
Biodiesel is a renewable fuel
produced from vegetable oils or
animal fats that have been
chemically modified to make it
compatible with diesel fuel.
Caution
Do not use home-made biodiesel
or home test kits because the
quality cannot be verified by
approved scientific methods. Do
not use raw vegetable oil or other
unmodified bio-oils, fats,
or blends of vegetable oil with
diesel. They could damage the
fuel system and engine, and
damages would not be covered
by the vehicle warranty.
Biodiesel Blends
Fuels with a biodiesel content up to
10% by volume may be used (e.g.,
named B10). Only use biodiesel
blends up to 10% by volume that
comply with your country
’
s or
region
’
s fuel standards.
Caution
Do not use blends containing
more than 10% biodiesel. Any
engine, fuel system, or exhaust
after-treatment system damage
would not be covered by the
vehicle warranty.
As a renewable fuel, biodiesel
provides some environmental
benefits. However, biodiesel has
unique properties and needs to be
handled differently than diesel fuel.
Its use presents additional risks and
may not be appropriate in all
situations. Certain vehicle operating
modes increase these risks and
should be avoided.
Biodiesel fuel quality degrades with
time and exposure to high
temperature quicker than Ultra Low
Sulfur Diesel fuel. More frequent
refueling provides the best
opportunity to have a supply of fresh
fuel. Storage at hot ambient
temperatures will accelerate
biodiesel degradation.
Owners who use little fuel, or who
have vehicles stored for extended
periods of time, should avoid the
use of biodiesel blended fuels
above 5% by volume. When
vehicles are stored for longer than
one month, they should be run out
of biodiesel to below one quarter
tank, refueled with biodiesel-free
diesel fuel, and driven several
kilometers (miles) before storage.
Filling the Tank
Caution
If you use inappropriate grade
fuel or put incorrect fuel additives
into the fuel tank, the engine and
catalytic converter may be
seriously damaged.
Be sure to use the correct fuel
corresponding to the vehicle
when refuelling. If you put
gasoline in the diesel powered
vehicle, for example, the vehicle
can be seriously damaged. If the
