If I needed a large bottle of oil I would probably just get a pure mineral oil SAE 10-15 or something like that.; regular chain and sewing machine oil. A light synthetic equivalent might be an improvment. Applying, turning the pedals and wiping off should be enough, but in my dusty and gritty conditions I need to hose off, wipe off and reapply after each ride for optimal upkeep of the chain. So far I have yet to succeed with dry wax based lubricants.

My favorite oil is Finish Line Ceramic Wet Lube, so maybe a light synthetic oil by the gallon added nano particle teflon and boron nitride? A generic spray can oil for quick and easy cleanin is good too: a light mineral oil with a large dose of hexane, white spirit and clever rust inhibitors. The problem is to track down the basic pure oil with out too much detergents and additives for the base.
