Johnson Biofuels produces and distributes b100 (100% biodiesel) or 99.9% biodiesel. All of our biodiesel is produced to the highest quality standard and guaranteed to meet the American Society for Testing Materials (ASTM) specifications of D-6751.

Our rigorous process validation and subsequent quality control ensures that each batch of biodiesel produced meets or exceeds ASTM D-6751. A sample from each batch is removed and then verified and tested by an independent certified laboratory.

We only sell biodiesel that we produce, thus we have control over the entire quality system. The responsibility of ensuring fuel quality falls with the individual producers and there are studies that show that many biodiesel producers are selling off-spec fuel. We encourage all biodiesel users to know their suppliers.
