I just picked up a pocket-sized "hypodermic" style oiler, and want to use it to hold a light oil. Since I can't find any good watch oil around here (I know it's available online), I'm wondering what is a good, non-gumming substitute. ISTR from several years back a comment on this ng that ATF was a good substitute for watch oil - any comments about that? Otherwise, I might just use Marvel Mystery Oil.
