NO. Biodiesel is produced from raw vegetable oils or animal fats, but the oil or fat must go through the chemical reaction (called transesterification) to make it into biodiesel and be tested to make sure it meets D 6751 before it is blended with heating oil. Unreacted or only partially reacted oils not meeting D 6751 can accelerate instability and contamination issues, create fouling and additional cold flow concerns, and increase hazardous emissions of formaldehyde and other aldehydes. Raw vegetable oils, cooking oil or animal fats do not meet D 6751, should not be blended with heating oil, and cannot be used to create Bioheat fuel.
