I have never tried Penzoil, but you can run Mobil 1 synthetic all day long in your guns with no problems. I just dont like the smell after a while.

That will never work.

You MUST use the latest MAGPUL/Costa Ludus/Daniel Defense/Noveske lubricant.

And it must say TACTICAL on the container.

Ask yourself; would I put CLP or FrogLube in my car?

Why do that to your guns?

And then your guns get back to me, and I spend hours repairing and replacing worn out, clogged, and burned up parts absolutely because of improper lubing.

When your Mobile 1 burns totally away in a firefight and deposits chemical residues that will lock up any machine gun, leaving your squad or company at severe risk because you were stupid... how great of an idea will it be then??

Motor oil is fine, but is doesn't contain the anti-corrosives that a gun oil does. It will rust much quicker than with gun oils. As long as you store the guns in a nice dry place you'll be fine.

I'd imagine that a motor oil containing moly would be beneficial, but unfortunately for me, I only store motor oils that DO NOT contain moly. So I think I'll pass on this tip. I do think it could work for others though. Doubt this would work much better than Rem Oil or Hoppes Gun Lubricant, which I already have ample supply of.

Because, when your out for 48 days without a re supply you do what you have to do to get by and get back. That's way......

30W works fine but you can get away with all sorts of different weights (as well as greases) depending on the temperature. Personally I have had better luck with greases staying on the bolt/not burning off.

How about just mixing it ALL? Mobil 1, Lucas Oil, Olive oil, Corn oil, Militec, CLP :43:

Mobil One. On my AR and my AK. No issues. As for "burning off" and parts being worn out...if someone has data showing a significant difference between mobile 1 and "tactical lube" for smoke pint and viscosity break down @ higher gun temps it would help this discussion. From what I can find, Mobile 1 has a flash point of roughly 471 degrees F with some variation based on weight. I cant imagine any tacticool oil being significantly different. Would love to be proven wrong.

I've always used boat trailer wheel bearing grease for things like bolts and wear spots.

Nothing wrong with that. Motor oil is cheap, readily available, and does it's job at lubricating. Now if your guns are gonna be constantly exposed to a dusty environment and/or corrosive environment there are better options.

I've had several military people say Mobil 1 synthetic 30 weight is the best lube for the AR. Lots of cops too. One $5 bottle will last a lifetime.

A lot of rednecks eat their boogers too and haven't died from it.

Your choice if it's a good idea or not. Guns do not function the same way automobiles function. You're honestly better off using crisco in your guns then motor oil.

Oh that was friggin hilarious!

I think I'll just mostly stick to the same old Hoppes #9 gun oil I've been using with good results for nearly 25yrs...right tool for the job and it doesn't stink.

I won't get into Army/Navy, but if you are out 48 days with no re-supply, then your command failed you royally. If you knew you would be mobile...and what 0331 isn't...then YOU should have stocked up on correct lube prior to movement.

^^This in addition to the fact I can get Gun lubricants that when they burn off won't kill me in the long run.

There's no denying the fact that motor oil will work. Honestly how lubricant does one need anyways? I have a 4oz bottle of Slip EWL that has lasted me 2 years so far.

rubbing the side of their nose (where body produces much skin oil) and rubbing in on inner workings of their guns (AKs).

Diff between "gun oil" (and some bicycle oil) is something about 'not attracting dirt' because it is a synthetic or something.

I'll have to try an experiment sometime with Rem Oil vs Pennzoil and see if there is any diff in dirt after being outside for few days.

I used to use that on my AR. Because of the smell, I now use bearing grease. Some guys just don't understand how simple it really is… but whatever.

EVOO or better known as Extra Virgin Olive Oil is better than Crisco!

I use Jif peanut butter. Sticky, preserves, lubricates and tastes great. Be sure to use the tactical smooth jar and not the crunchy.

I use motor oil in my remington 870, it gets shot at the range cleaned and cased. It just dawned on me the other day to use it on my AR, but I have not. I've been using CLP or hoppes #9. I believe the arguements against are very valid, however for the benchrest shooter such as myself who is likely to clean it all off from boredom after a range session I doubt one should loose any sleep.

Other than that I'd be against it except in a bind the same way that I would only use 30 weight motor oil in a chainsaw in a bind. It's not it's intended purpose and wont perform as well as a lubricant intended for that purpose. In my analogy of the chainsaw regular 30w will sling off the chain and wear the bar faster than real bar oil will. The same way WD40 attracts dirt to a bike chain I bet motor oil would be hard on an AR in the long term.

It's 2012, we have much better options for gun lube than using motor oil, and they aren't expensive.

Just wanted to know what you all think about this.

raceraxe,

This is not a new issue. Many people have been using motor oil for years as a general lubricant for firearms. Some people have said that gun oil is nothing more than a light weight motor oil anyway. If you You Tube some more you'll find people use grease to lube the BCG's as well on the rails only and a light coating/film of oil on the outside.

If you think about it any lube will suffice. Just don't drown it out like some people do. I prefer to use just enough and not too much. For my overall lube and cleaner I just use Breakfree now but have several oil collected over the years and so I have so much my collective will last seven more years!

Perhaps so :)

But I do know how a machine gunner should operate, and packing a gallon of CLP in the truck specifically for your guns is light years better than hoping motor oil will keep you running in a firefight.

Redline synthetic two-stroke oil. No residue when burned. Cheaper than the newest BS lube used by ninja warriors.

This is what I tell my wife: When you're in a Pho place, order Pho. When you're in a burger joint, order burgers. Yes, you can order the rice dish or the scramble eggs, etc. and you'll live, but it won't be as good.

Same logic here: Yes, you can use motor oil, and if you're stuck out in the desert fighting a war and there is nothing else around, do it, it's better than nothing. But if you're home and you have an extra $5, buy the CLP for your guns -- that's what they were designed for!!!
