Biodiesel Flashpoint

Search this site!

The lowest temperature at which the fuel will ignite if exposed to a flame is referred to as its flashpoint.

• ASTM certified B100 must have a flashpoint greater than 266°F (130°C). Flashpoint will vary due to different feedstocks and other factors. Some biodiesel has had flashpoints greater than 300°F!

• In comparison, petroleum diesel must have a flashpoint greater than only 100°F (38°C) for type #1, or 126°F (52°C) for type #2 in order to pass ASTM standards.


In Summary:

The higher flashpoint makes it a much safer substance than petroleum diesel to have around.
