I might try the Dumonde Tech Lite or Original Bicycle Chain Lubrication. According to Dumonde the Original and the Lite is the same thing but Lite is diluted version of the Original so why use the Lite? why not use the Original but less of it vs the Lite?
I have not used that product, but my best guess is that maybe the process of application and wiping off cleans the chain better with the diluted product. That wouldn't be a plus for those who clean the chain first with other solvents or detergents.
Also using less may not be easy since they specify very light application. They say, "One ounce of Dumonde Tech should give you at least 10 applications." How would you use less than 1/10 of an ounce? According to Google there are 591.5 drops per ounce so roughly 60 per 1/10 ounce. So if you were to put one drop per roller it would seem you would already be well over (almost double) the recommended 1/10 ounce.
Am I missing something here? Are you supposed to put a drop on every other link? Otherwise I don't see how you would get a chain lubed with 1/10 ounce.
I am a believer in avoiding over applying and in thoroughly wiping off all excess thinking the chain should look and feel dry, but 1/10 ounce isn't much, so a more dilute solution would allow better wiping off of excess. Dumonde also recommend that ("Apply sparingly and wipe off excess lubricant with a clean cloth to the point where the chain’s outer surface appears dry.").
