Synthetic motor oil for gun lube.

[Special T]

I read an article the other day about a soldier over in Afghanistan using 5-20 synthetic as gun lube for his M16. He stated that is seemed to work better than whatever they were using over there.
I normally use Rem Lube, but hunt the salt for ducks a lot and plan on tying this. Seems to me to be a much cheaper option and the writer said that it worked well in the dusty conditions of Afghanistan. Does anyone else use some kind of non gun specific lube on their guns? Article just got me thinking.

I use it on my M-4 and have never had issue in cold weather.  I use Beretta gun lube on my shotguns.

A few years ago I went to a hardware store and bought a thin sheet of metal. It cut it into small 2"x2" chips. I then applied various protectants to each strip: CLP, Rem Oil, WD40, etc. I left them outside in damp grass for one week, and compared results.

The clear winner in my test was, believe it or not: WD40. There were no rust. Every other product failed to one extent or another.

I did not include any motor oil in the test, but that might be an interesting one to try.

I'm looking forward to following this one. Interesting proposition, with an entire quart of motor oil probably costing the same as a small bottle of lube.

Regardless, I'm glad the military has finally gotten a clue that continuous, copious lubrication to M4/M16s is the simple key to keeping them from jamming in a dusty environment. Grease it up!

WD-40 does protect from rust well but it attracts dust and dirt. I would just use lube meant for guns frog lube for me!

Synthetic motor oil has been recommended to me by a maker of custom handguns

Most lubes attract dust and dirt. Still better to use more than less.

WD-40 is to a gunsmith like candy is to a dentist.  I used to make alot of money off hunters that would just spray WD-40 into the actions of their shotguns, the stuff eventually turns to a gummy varnish and can stop O/U's from switching barrel and slowing auto and pump stikes enough to get unreliable ignition.  Spray it on the outside if you feel you have to but use a good light gun oil for the insides.

 Johnsons paste wax works realy well for protecting your shotgun in salt areas, just wipe it on and don't buff it.

WD-40 is not really a lubricating oil. It is a water dispersing agent (WD). It is great at protecting from water or moisture but as a lubricant not ideal. 5w-20 is a pretty thin oil and being synthetic it doesn't absorb moisture like conventional oils. Also I would think it would protect well on a firearm that has had several hundred rounds down the pipe in one session. Probably better than gun oils. I may try this just to see how it does. This oil was designed for engines with very tight tolerances and holds up well with those tolerances and the heat generated from engines.

I use synthetic on my ar. Supposed to hold up well to the heat.

I have been preaching this since gunsmithing school.. but I am always told that pretty much I have no clue what I am talking about.
