Well, I believe a clean lubed chain is more efficient too....I'm just skeptical that adding oil at home actually lubes a chain. Dripping, dipping, soaking just ends up filling the internals with a mixture "made of oil and silicon dioxide (sand) and silicon carbide (sand). You couldn't do it better if you tried to destroy a chain" (quote Porsche Engineer and author of "The Bicycle Wheel", Jobst Brandt).
