A method and system to reduce fuel consumption and environmental impact in a two-stroke engine. Fresh system oil having a TBN less than 10 is provided and used in the two-stroke engine to produce partially used system oil. The partially used system oil is withdrawn from the two stroke engine and at least one friction modifier is added to at least some of the withdrawn partially used system oil, wherein the addition of the at least one friction modifier reduces the friction coefficient of the withdrawn system oil, resulting in a system oil having reduced friction. The system oil with reduced friction is combined with partially used system oil remaining in said two-stroke and the combined system oil is used to lubricate pistons of said two-stroke engine.

Method and system for improving fuel economy and environmental impact operating a 2-stroke engine

A method and system of creating a cylinder oil having a target TBN ranging from 40 to 70 for use in a two-stroke en line. Fresh system oil having a TBN less than 10 is provided. The fresh system oil is used in the two-stroke engine to product partially used system oil. An initial fluid containing at least some partially used system oil is provided. A first TBN of the initial fluid is determined. Cylinder oil having the target TBN is created by blending the initial fluid having the first TBN with at least one suited additive. The cylinder oil is provided to the two-stroke engine.
