I think some is better than none! I'm not a fan of "dry" graphite type lube. I have been using a hydraulic oil "R&O" (rust and oxidation) and it seems to be working well, it's a "light" weight - comparable with "5" or "10" weight and penetrates very well. For the open gear I've used a wheel bearing grease , spread a layer with my fingers and wipe off any excess (blobs) with a clean towel/rag. I like to clean away and repeat/refresh every month or so. Also my machines are weekend warriors.. so use is light imho.
