I’ve tried a bunch of commercial gun stuff, used Mobil 1 30 wt, tried 3 in 1, Singer and other lightweight machine oil, Ed’s Red-type homemade blends, new “high speed” stuff like Slip2000EWL, Froglube, etc.
If you take care of your guns properly, I seriously believe any one of these lubricants will work for the vast majority of your shooting and/or storage needs.
I’m currently using Lucas green... it came in a big bottle, it is easy to use, tacky enough to stick on AR bolts and pistol slides, and it doesn’t stink.
Once that’s gone, which at the rate I’m using it will be sometime in mid-2020, I may or may not buy more, that’s the fun of living here in the US; choices!
Stay safe.
