Bio-additive for diesel fuel jet fuel, other fuels and lubricants

Abstract

Compositions and methods of making bio-additives for diesel fuel, jet fuel and other fuels and lubricant formulations are presented. The compositions include a first polyalphaolefin, a second polyalphaolefin, a polyolefinic ester, a calcium overbased sulfonate, and a bean oil or seed oil. The fuel additives can be added to any fuel and result in advantages, such as a lower cloud point and a better lubricated engine.
