ASTM- American Society
of Testing and Materials (ASTM),
issued a fuel specification for BioDiesel
(D6751), in December 2001.
BioDiesel provides improved lubricity.
Ultra-low sulfur petroleum diesel
has reduced lubricity, which may cause premature
wear or malfunction. A 20% blend of BioDiesel with
an 80% blend of petroleum diesel (B20) can reduce emissions
and eliminate any need for lubrication additives.
Harmful emissions are reduced with BioDiesel
and BioDiesel blends. Petroleum diesel
exhaust is listed by the Environmental
Protection Agency (EPA), as a known carcinogen
(cancer causing), and is listed as a Toxic Air Contaminant
(TAC). Using BioDiesel reduces harmful toxins
and helps to protect workers that are exposed to
diesel engine exhaust.
