Alternative organic fuel formulations including vegetable oil and petroleum diesel

Abstract

Fuel formulations may be produced from vegetable oil without the need to remove glycerin from the vegetable oil prior to use. The fuel formulations may be used in diesel fuel vehicles and/or as a home heating oil. The fuel formulations may include vegetable oil, petroleum diesel, a fuel stabilizer, and a cetane boost additive.
