Biodiesel - Chemistry
It is not vegetable oils or animal fats, it is made from vegetable oil or animal fat.
The oils and fats are chemically altered to make Biodiesel, a mono alkyl ester (methyl ester).
They will gum up the engine, if not chemically altered. +

Using Biodiesel - Know Your Biodiesel Supplier
The B100 biodiesel fuel used in the blend must be sourced from a BQ-9000 Accredited Producer.
Certified Marketers and Producers can be found at the following website:
National Biodiesel Board :
Every batch of biodiesel is tested to meet ASTM 6751 standards.
Ask your supplier for a copy of test for your B-100.

5. Using Biodiesel - Solvent

Using Biodiesel - Solvent
Filters can clog on initial use, especially with B20 and higher blends.
Due to the solvent nature of biodiesel, and the potential for “cleaning” of the vehicle fuel tank and lines, new fuel filters must be installed when switching to biodiesel on used engines. Fuel filters will need to be replaced at half the standard interval for the next two fuel filter changes.

Using Biodiesel – Materials
Natural rubber, nitrile, and butile rubber are particularly susceptible to degradation. Also, copper, bronze, brass, tin, lead, and zinc can cause deposit formations. The use of these materials and coatings must be avoided for fuel tanks and fuel lines.

8. Using Biodiesel - Storage
Cummins Global Brand

Using Biodiesel - Storage
Use biodiesel fuel within six months of its manufacture. Biodiesel has poor oxidation stability, which can result in long term storage problems.

9. Using Biodiesel - Microbial Growth

Using Biodiesel - Microbial Growth
Biodiesel fuel is an excellent medium for microbial growth. Microbes cause fuel system corrosion and premature filter plugging. The effectiveness of all commercially available conventional anti-microbial additives, when used in biodiesel, is not known.

10. Using Biodiesel – Colder Temperatures
Cummins Global Brand

Using Biodiesel – Colder Temperatures
Biodiesel fuel properties change at low temperatures, which can pose problems for both storage and operability.
Filters can plug and fuel in the tank can solidify at low temperatures if precautions are not taken storage tank, or using cold temperature additives.
B2 – raises (CFFP) about 2 degrees F
B20 – raises (CFFP) about 7 degrees F
B100 – freezes at 32 degrees F
