Shotgun Oil

[HunterColbert]

Over the last few years I have noticed a lot of oils do not work well on the Benelli shotgun My question is - What do yall find is the best oil to use for you shotguns? I'm looking for something that wont gel up in cold and harsh conditions. It is hard to pinpoint good oil these days.

I use 1/2 synthetic 10-30 motor oil and 1/2 transmission fluid which makes 1/2 gallon, enough for my lifetime. Those are made to lube parts that run far hotter and faster than my BENELLI M4 ever will. IMO those tiny bottles of "gun oil" are WAY overpriced. YMMV

I really like this.  CLP is a good product as well for your bolt.  Outside of that Mobil 1 super low viscosity.

I recommend to NEVER use a 'wet' oil in your magazine tube. I have made a decent amount of money over the years buying "jam-o-matics' that wouldn't feed after a quick look down the tube. I'd take them home, clean out all the dried chaff, dust, leaves, and everything else the environment kicks up that the wet oil will gladly stick to until it eventually traps so much of it that it gums up the works. I even sold some back to their original owners after they saw they shot flawlessly again. I'd purposely bring their old gun with me when I'd hunt with them just to show them it wasn't the gun. 😇

So, I started with dry lube in the magazine, then started using it elsewhere. Ultimately, I now run it everywhere else including in the bolt, though I do put a small drop of oil on the frame rails. I spread it nice and thin, wiping off any excess before putting my Super Black Eagle back together (my main hunting shotgun). I don't know if the gas operated M4 would need a different oil anywhere, but I've got a LOT of rounds, including a lot of 3.5" mags down my SBE and it still looks and runs like a champ inside and out. 
I use the cheap RemOil for non-moving parts as a rust-preventer for storage but after having a bolt literally freeze shut at 10 degrees F, I quit using it on moving parts. I put it on evenly, then wipe off the excess. I then put them in modified silicone gun socks so the Rifle Rods gun storage system rods would pass through and they give some limited protection against safe rash of guns bumping together.

I have been using Geissele's Go Juice. I like that it is non-toxic.

I have run it in single degree weather without any issues. Not super cold, but it is what it is.

I use hornady one shot in my shotguns. Ive run that in negative temps with no issues. Otherwise a good penzoil synthetic 0 or 5w20, slip2000 and breakthrough hp oil have worked well.

It flows much smoother with transmission fluid. YMMV

Use the oil Benelli included with it.
