Biodiesel
What is biodiesel?
Biodiesel is a fuel produced from
vegetable oils or animal fats that
have been chemically modified to
reduce the possibility of damage to
the fuel system and engine.
{
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.
What not to use
Do not use home-made biodiesel in
your vehicle since its quality cannot
be verified by approved scientific
methods. Home test kits are not
approved scientific methods.
{
Caution
Any damage caused by raw,
unmodified, or home-made
biodiesel would not be covered by
the vehicle warranty.

commonly known as Ultra Low
Sulfur Diesel), as other fuels used in
your vehicle, and the biodiesel used
for making this fuel must meet the
latest version of ASTM specification
D6751.
