I don't really consider Kroil (love the stuff) as a lubricating oil necessarily. I only use it to penetrate carbon fouling. Maybe I'm wrong.
You are correct. Do NOT rely on Kroil for rust prevention either, despite several recommendations above and elsewhere on this forum to wipe down your guns with it. Kroil has zero rust prevention qualities, and very little lubrication. It is specifically designed to be as thin as possible for penetration, it is not a miracle do-all oil.
The rust prevention is a pretty easy test for anyone who doesn't believe me, or is just wondering about a different oil. Just wipe a little on a piece of bare steel like you would on a gun and leave it outside for a couple weeks. For best results use a known good oil like CorrosionX on one part of the steel for comparison.
