This question always amazes me. It amazes me because I assume that the people posting this are posting from their home, or work, or library. Which means, hey, this person has access to the internet. Which means, hey, this person could go to Google, search "Rem Oil" or "Gun Butter" or "gun lubrication", and then find somewhere online to buy the stuff.
Motor oil works for your car. It is NOT designed for handguns. I'm sorry if I seem like an @** here, but this drives me NUTS. You would not pour Rem Oil in your car, do not put motor oil on your gun.
Go online, find somewhere that sells it online, I assume you have a Post Office or a mailbox (like me, I live out in the boonies), if you don't have a credit card then find a site that will take money orders or find a friend with a credit card that you can pay back, and buy the proper lubricants for your gun, PLEASE.
