Don't forget motor oil(car oil). Works great and for $2 to $7(regular to synthetic) and you have enough in 1 quart to last you and all your shooting buddies. Doesn't burn off by gun's heat, won't freeze up in the firing pin/spring action, cleans easily, has additives for no-rust and carbon deposits, and can get in different weights for anybody's preference and always available close by without going to any gun store. Get in same weight as what you use for your vehicle and you have some oil to top up your motor, until next oil change. Just get a small plunger or bulb type surenge(sp) for light injection purposes. Works great, and won't attack blueing or matte finishes. Just remember that a little bit goes a long way.
