Title: Synthetic motor oil for gun lube.
Post by: Special T on September 28, 2012, 11:46:33 AM: 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. :twocents:

Post by: Bob33 on September 28, 2012, 11:56:42 AM: 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.

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!

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

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.

Post by: timberghost72 on September 28, 2012, 08:45:26 PM: 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.

Concurs on WD-40.

Best easily available: Dexron ATF

Best: Lubriplate food machinery greases and oils.

That was a great link, pretty much covers everything on auto oils and WD-40 and a great reference for finding GOOD
lubes.

Thank You

Post by: timberghost72 on September 28, 2012, 10:13:53 PM: ATF is probably pretty good as its a detergent based oil. But very messy and it seems to get everywhere. I would't use it.
Title: Re: Synthetic motor oil for gun lube.
Post by: wraithen on September 28, 2012, 10:26:15 PM: In those environments I want something with a more permanent coating like my all time favorite for my 240's which is a mixture of lsa or lsa-t and a super expensive commercial oil that sent us a package when requested for free. You could easily use motor oil but it will attract dust and dirt. If you're going to put your guns through hell just keep them wet with lube. It works on all things I love! :tup:

Post by: Jim the Plumber on September 29, 2012, 06:05:26 AM: Yup, I use Silkoline Pro 4 Plus 10-50. Works great on my many AR-15 type rifles.

NP. Later in his blog he notes that he received praise from a lubrication industry professional that it is about the best intro article on lube he had seen on the topic.

Also, the GC blog is pretty good.

I haven't used ATF yet, but I might give it a try, despite the warning about it getting everywhere.

Post by: FALFire on September 29, 2012, 07:05:00 AM: I've been using Mobil 1 for nearly 20 years on my AR's, never had a problem with them not functioning in every possible climate here in the PNW. During high rate of fire sessions, my guns ran where the other guys hung up for one reason or the other.

Post by: 300rum on September 29, 2012, 09:02:27 AM: Many competition shooters who shoot 10's of thousands of rounds a year use Mobile 1. I use Slide glide on my competition guns but on a carry gun Mobile 1 does the trick or when shooting at below freezing temps.

Post by: mebco09 on September 29, 2012, 08:03:23 PM: On my M1 Garand I use Lubrimatic high temp wheel bearing grease. Those heavy semi-autos need grease that stays put. Never tried it on anything else. My guess is that it might cause issues.
