I say I would like to bet you a cyber Internet lobster dinner with all the trimmings that...
We take two of the same guns, and side by side continue firing them constantly until one of them fails from carbon, crud and lack of lubrication. Most likely, the one lubed with the oil will be the one that failed.
Look at you AR take down pins, the frame where the slide meets on your pistol, etc. etc. You'll see oil there. That's oil that wants to run and escape from what it's suppose to be protecting. Oil will work well if you're only going to shoot a few hundred rounds with some breaks inbetween. Take a serious pistol / rifle training course or put your weapon through a serious training session and see how well oil does for you.
IMO, you're better off with lithium high temperature wheel bearing grease or Luberplate #10 grease. The exception being in environments below 30 degrees.
And just so you know, I like lots of cyber butter with my cyber lobster and a busty cyber waitress with artificial intelligence (A.I.).
