2. It allows the creep or flow by reducing surface tension. If you have ever noticed water flowing on a surface, and have taken your finger and made a new path for the water to follow it begins to also follow the newly wetted trail.
Planb submitted the correct response and in so doing receives the BITOG virtual Coffee Mug with the Piston Cup logo embossed.
An older post to which I referenced as a Hint, Multi-Functional Lubricants
stated the following:
Surfactants or Surface Active Agents (Protective Additive): family of diphenylamines and amides; usually part of the antioxidant package. Also provides enhanced friction reduction and allows oils to "climb" or spread on and over surfaces. Decreases but does not destroy surface tension
Some call the action, "Creep." In either case, it allows the lubricant to fully cover machine parts that may not get splashed or otherwise come into direct contact with the lubricant..
CVT ATF's have an especially powerful surfactant contained therein.
