Polyether- or polyester-modified polydimethylsiloxane is mixed with a lubricant, such as motor oil. Preferably, the polydialkylsiloxane can form at least about 0.5 percent by volume of the mixture. And the mixture can be used in a fluid-conduit system (e.g., a lubrication system) of a motor or a vehicle (e.g., an automobile), wherein the mixture offers excellent filming properties on, e.g., engine parts and helps to improve engine efficiency, to lengthen the service life of the lubricant, and to reduce harmful emissions from the vehicle.
