Definition: BIODIESEL, n—a fuel composed of mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats, designated B100, and meeting the requirements of ASTM (American Society Technical for Testing & Materials) D 6751 _________________________________________________________________________ _________________________________________________________________________ Myth: Engine warranty coverage would be at risk. Fact: The use of BIODIESEL in existing diesel engines does not void parts and materials workmanship warranties of any major US engine manufacturer. It is in fact illegal for a car manufacturer to void your warranty for using BIODIESEL. Myth: BIODIESEL is an experimental fuel and has not been thoroughly tested. Fact: BIODIESEL is one of the most thoroughly tested alternative fuels on the market. A number of independent studies have been completed with the results showing BIODIESEL performs similar to petroleum diesel while benefiting the environment and human health compared to diesel. That research includes studies performed by the U.S. Department of Energy, the U.S. Department of Agriculture, Stanadyne Automotive Corp. (the largest diesel fuel injection equipment manufacturer in the U.S.), Lovelace Respiratory Research Institute, and Southwest Research Institute. BIODIESEL is the first and only alternative fuel to have completed the rigorous Health Effects testing requirement sod the Clean Air Act. BIODIESEL has been proven to perform similarly to diesel in more 50 million successful road miles in virtually all types of diesel engines, countless off-road miles and countless marine hours. Currently more than 300 major fleets use the fuel. Myth: BIODIESEL does not perform as well as diesel. Fact: One of the major advantages of BIODIESEL is the fact that it can be used in existing engines and fuel injection equipment with little impact to operating performance. BIODIESEL has a higher cetane number than U.S. Diesel fuel. In more than 50 million miles of in-field demonstrations, B20 showed similar fuel consumption, horsepower, torque, and haulage rates as conventional Diesel fuel. BIODIESEL also has superior lubricity and it has the highest BTU content of any alternative fuel (falling in the range between #1 and #2 Diesel fuel). Myth: BIODIESEL doesn't perform well in cold weather. Fact: BIODIESEL will gel in very cold temperatures, just as the common #2 Diesel does. Although pure BIODIESEL has a higher cloud point than #2 Diesel fuel, typical blends of 20% BIODIESEL are managed with the same fuel management techniques as #2 Diesel. Blends of 5% BIODIESEL and less have virtually no impact on cold flow. Myth: BIODIESEL causes filters to plug. Fact: BIODIESEL can be operated in any Diesel engine with little or no modification to the engine or the fuel system. Pure BIODIESEL (B100) has a solvent effect, which may release deposits accumulated on tank walls and pipes from previous Diesel fuel use. With high blends of BIODIESEL, the release of deposits may clog filters initially and precautions should be taken to replace fuel filters until the petroleum build-up is eliminated. This issue is less prevalent with B20 blends, and there is no evidence that lower-blend levels such as B2 have caused filters to plug. Myth: BIODIESEL causes degradation of engine gaskets and seals. Fact: The recent switch to low-sulfur Diesel fuel has caused most Original Equipment Manufacturers (OEMs) to switch to components that are also suitable for use with BIODIESEL. In general, BIODIESEL used in pure form can soften and degrade certain types of elastomer's and natural rubber compounds over time. Using high percent blends can impact fuel system components (primarily fuel hoses and fuel pump seals) that contain elastomer compounds incompatible with BIODIESEL, although the effect is lessened as the BIODIESEL blend level is decreased. Experience with B20 has found that no changes to gaskets or hoses are necessary. Myth: No objective BIODIESEL fuel formulation standard exists. Fact: The BIODIESEL industry has been active in setting standards for BIODIESEL since 1994 when the first BIODIESEL task force was formed within the American Society for Testing and Materials (ASTM). ASTM approved a provisional standard for BIODIESEL (ASTM PS 121) in July of 1999. The final specification (D-6751) was issued in December 2001. Copies of specifications are available from ASTM at http://www.astm.org.

Can BIODIESEL
help mitigate
“global
warming”?
BIODIESEL is the best
greenhouse gas
mitigation strategy for
today’s medium and
heavy
duty vehicles. A 1998
BIODIESEL life cycle
study, jointly
sponsored by the U.S.
Department
of Energy and the U.S.
Department of
Agriculture, concluded
BIODIESEL reduces
net carbon dioxide
emissions by 78
percent compared to
petroleum diesel. This
is due to
BIODIESEL’s closed
carbon cycle. The CO²
released into the
atmosphere when
BIODIESEL
is burned is recycled
by gro which are later
processed into fuel.
IS BIODIESEL better
for human health
than petroleum
diesel?
Scientific research
confirms that BIODIESEL
exhaust has a less
harmful impact on human
health than petroleum
diesel fuel. Pure
BIODIESEL emissions
have decreased levels of
polly cyclic aromatic
hydrocarbons (PAH) and
nitrited PAH compounds
that have been
identified as potential
cancer causing
compounds. Also,
particulate matter, an
emission linked to
asthma and other
diseases, is reduced by
about 47 percent, and
carbon monoxide, a
poisonous gas, is
reduced by about 48
percent.

Is BIODIESEL used as
a pure fuel or is it
blended with
petroleum diesel?
BIODIESEL can be used as a
pure fuel or blended with
petroleum in any percentage.
B20 (a blend of 20 percent
BIODIESEL with 80 percent
petroleum diesel) has
demonstrated significant
environmental benefits with a
minimum increase in cost for
fleet operations and other
consumers
FACT; 31 states have
already introduced legislation
to implement the use of
BIODIESEL.
FACT; the US military is
