I’ve seen several demonstrations for these additives, and several SEEM to make a good point. The one I saw of Lucas products SEEM to should an enhanced ability to both flow and adherence to the internals. However, I firmly believe that the best protection is frequent/timely scheduled lubrication changes using the prescribed grades of lubricants and filters. Nothing protects against millions of tiny microns of dirt and metal floating about in a sea of dirty oil. The one exception may be when you have a neglected piece of rotating equipment in which the internals are severely contaminated. Using some of these additives may be of some service as a detergent supplement – two of which come to mind are Sea-Foam and Reslone – Both of which I feel should only be used for a brief time as a cleaning agent, as I believe both will severely dilute the viscosity of the lubricant (i.e., to be used as a flush).
