ADDITIVE SUPPLEMENTS FOR OIL CHANGES

A method of producing an additive supplement that when combined with a motor oil licensable with the American Petroleum Institute and the International Lubricant Standardization and Approval Committee creates a second motor oil that meets the standards of the American Petroleum Institute and the International Lubricant Standardization and Approval Committee by first selecting a desired motor oil and a standard motor oil, wherein the desired motor oil comprises a desired base oil component and a desired additive component and the standard motor oil contains a standard base oil component and a standard additive component. A differentiating additive component is produced by determining the additive component differences between the desired additive component and the standard additive component. This differentiating additive component is determined by using equal amounts of the standard motor oil and the desired motor oil. An optional step can then be performed of adding additional additives to the differentiating additive component to produce a preferred additive component. Sufficient base oil is then incorporated to the preferred additive component to produce an additive supplement.
