Composition and Methods for Improved Lubrication, Pour Point, and Fuel Performance

Abstract

An additive includes polyalphaolefin (PAO), a calcium source, and one or more oils from, or components derived from, beans, seeds, or roots, such as castor oil, jojoba oil, rape (canola) seed oil, palm oil, sunflower oil, soybean oil, etc. The preferred composition of matter comprises a calcium source, PAO, castor oil, jojoba oil, and a soy methyl ester and/or rape seed methyl or ethyl ester. The additive may be used in fuels that improve combustion engine performance in terms of efficiency and emissions. The additive may be used in lubricants that improve performance of both ferrous and non-ferrous metal components of engines, guns, or other machinery. The additive also may be used in cutting fluids for machining and fabrication. Used in conjunction with other additives, embodiments of the invention may be used, to lower pour points in oils, esters and other similar products.
