I had read somewhere that motor oil for vehicles, makes a good gun lubricant, kind of makes sense as its formulated for long life, extreme heat and friction....anyone who does or has id like to hear opinions?
 
Any kind of liquid lube is going to for a gunk over time from dirt and dust mixing with it. I prefer to use a dry lube..it wont collect dirt and wont gum up no matter how cold or run no matter how hot.
 
I have heard of guys using light weight synthetic and it may do great. To me motor oil is intended to be run in a warm regulated temp engine. I don't run my guns that warm. If you put gun lubricant in an engine it probably won't last to long. I just like to stick with time tested stuff by manufacturers and military.
 
If you are going to store a weapon for a long time, a non-detergent heavy motor oil will work well (submersing it in Mineral Oil is better), but as stated, it is too heavy and will collect too much dust, etc.
 
I have talked to a few gunsmiths who swear by STP oil treatment for lubing over/under shotgun bearing surfaces.

I use Rem-Oil on just about everything that doesn't get grease like hinge pins on my Browning 525 skeet gun. I use Slick 50 automotive grease. One tube is a lifetime supply.
 
I used 10w-40 during one duck hunting trip because My mossberg shotgun seized up on me. It had been in the water and mud all morning and we had done lot of shooting. Later that afternoon we went quail hunting and it seized up solid. I poored the motor oil into the action and slammed open and shut a few times. Worked great other than the smell. It would not be my 1st choice though. now I carry a small bottle of hopps #9 in my vehicles.

HAHA that's funny, not because of using motor oil but that same thing happened to me this past week during a goose hunt. My shotgun got so cold it was recoiling very slow. All I had was some motor oil out of one of the atv's. So out comes the dip stick and rubbed some on the rails, it ran like greased snot after that. /ubbthreads/images/graemlins/laugh.gif
 
I never thought about the detergents and additives for engines. One time we tore down a heavy truck engine that the farmer had religiously used Conoco oil from day one. It was pink inside.
 
I use a lube called royal purple on my AR moving parts. It is a synthetic oil and has worked really well so far. My dad is an oil analysis engineer and swears by this stuff. He has been testing oils for 20+ years for the company he works for and runs this line of oil in all his cars and toys. My sister hit a rock that had fallen into the road it puntured the oil pan and the engine ran 22 or so miles with no oil in the car at all. The compression was ok and after a new oil pan and an oil change the car ran another 6 years with no problems.

So my dad got a little bottle of lube that this company made, that the rep said would be awesome for gun lube. It has been great so far for me.
 
A non detergent motor oil thinned with mineral spirits is a good quench for a fresh blue job. For every thing else I use one of the hundreds of good gun oils on the market.
 
For my rifles and shotguns I use any old "gun oil". For my high performance IPSC race pistols I use Mobile One or lightweight synthetic compressor oil. Kind of depends on the application.
 
We once ran out of lubricant for the M2 50BMG when I was deployed. All we had on the HMMWV was a quart of transmission fluid. Flipped open the feedtray and poured it in. Cycled the bolt a few times and she ran slicker than goose poop!

Wouldn't reccomend for all occasions, cause like motor oil, it literally sucked dust out of the air! But, it did the trick till we could get some of the good stuff.
 
My first choice is 3 in One sewing Machine Oil. Used it for too many years to mention. I am out right now so I am using Air Tool oil which is too sticky.
 
i like Liquid Fire paint ball gun oil it is scent free also like graphite powder for frozen car door locks ~ works very well and also scent free
