Dear Jane,

A Word About Biodiesel

Biodiesel is a cleaner burning diesel fuel made from vegetable oil. Simply stated, a biodiesel molecule is a vegetable oil molecule with the glycerol removed. Chemically, biodiesel is defined as a mono-alkyl ester of vegetable oil.

How Biodiesel Differs from Vegetable Oil

Biodiesel is NOT the same as raw vegetable oil or straight vegetable oil (SVO). Diesel engines actually can operate on straight vegetable oil (SVO) as a fuel. In fact, Rudolf Diesel's first compression ignition (Diesel) engine introduced in 1895 used peanut oil as its fuel. Modern diesel equipment, however, requires some modification to burn straight vegetable oil, and it is yet unclear the effects of straight vegetable oil on diesel engine performance and longevity.

Will biodiesel void my engine warranty?

According to the National Renewable Energy Laboratory, "Original Engine Manufactures (OEM) provide a material and workmanship warranty on their products. Such warranties do not cover damage caused by external conditions, such as fuel. Thus, if an engine using biodiesel experiences a failure unrelated to the biodiesel use, it MUST be covered by the OEM's warranty. Federal law prohibits the voiding of a warranty just because biodiesel was used - it has to be the cause of the failure. If an engine experiences a failure caused by biodiesel (or any other external condition, such as bad diesel fuel), it will not be covered by the OEM's warranty.".

Sincerely,
