Has anyone ever used this for gun lube before? I heard about it on the Sig forum but I wanted to make sure that it would not cause problems with a polymer frame.

Yes, and it's good. I have one tube (meant for a grease gun) that I assume is a lifetime supply many times over.

I have been using Mobil 1 5w30 oil to lube my guns for quite some time now and am very pleased with the results.

Doubt that I'll be buying anything else from here on out. None of my guns require grease so I look forward to hearing how it works for you.

I don't think it would cause problems for a polymer frame. However, my guess is the recommendation from the SIG forum is to use the grease on the aluminum framed SIGs as they seem to have problems with them if not lubed properly, and preferably with grease.

Gray Guns http://grayguns.com/lubrication-of-sig-sauer-pistol-rails/

Polymer pistols typically have simple lube needs. They have very short frame rails (typically) and those rails are steel meeting up with a steel slide. Use whatever you want for lube.

For what it's worth, I've also used Mobil 1 5w-30 to lube my guns. It works well, but even at that thin level, it is much thicker than BreakFree CLP, SLIP 2000, and Ballistol, three other lubes I use.

Sentry Hi-Slip Grease, I know of nothing better. Or nothing even close. Tested and approved by the Military. Used by Seal Teams and Spec. Forces (if you can believe the label). Will not wash off in water. Lubes from 60 degrees below zero (and will not thicken) to 700 degrees above (and will not liquify). I've used it for a few years and think it's great. I would not think of switching. I recently fired some firearms that I had lubed and stored for approx. 2 years ++. No lube added, straight to the range and shoot. All ran like a top with no malfunctions. Also as much a test for Magpul mags as lube. The mags ran flawless after storing fully loaded for 2 years. I thought Sentry would be good to go. But suspected the Magpul might not run, being made of plastic. I no longer have a question about Magpul, they worked fine.

That's why I like it. It's kind of the best of both worlds.

Here's a good article on gun grease by Grant Cunningham, a noted gunsmith: http://www.grantcunningham.com/lubricants101.html

Never tried that, but I have been using Super-Tech (Wal-mart brand) "General Purpose Lithium Grease" on the slide rails of several guns lately with good results. Three tubes of it cost like $3 and all I do is dab a toothpick in the tube and then apply to the rails. Wipe away the excess after the slide is back on and it works great.

I've also got a bottle of 5w-30 motor oil (also Walmart generic :)) that I use as to surface oil the guns occasionally, but its still a tad thicker and I've gone back to mostly using 3-in-1.

I'm a firm believer in using general purpose stuff rather than anything gun specific.

Once my current bottle of Hoppe's #9 runs out I'm probably going to make a batch of Ed's Red cleaner as well.

Mobil 1 ATF fluid is actually recommended by Pardini for their guns (or so I hear).

When using motor oil, I would recommend non-detergent oil (not the detergent oil that you put in your car). The reason is that detergent oils are designed to soak up moisture (from surfaces or air) when cool, but the give it back up when heated to operating temperatures as in automotive engines, where the vapor is carried away by the crank-case ventilation system. Machine tool bearings, etc. that do not get very hot, or non-ventilated crank-case engines generally should not use detergent oil, since it will eventually saturate with moisture and can then cause corrosion. Non-detergent oil does not absorb moisture, but displaces it, which works better in an environment that does not heat up regularly or is not ventilated when it does heat up.

I don't know whether synthetic oils have the same moisture absorbing capabilities without detergents (or if they are available without detergents), so this may not apply to them.

And of course if you regularly clean and re-lube your firearms, this may not matter as much unless you intend to store the firearm unused for a potentially extended period of time.

I have used "Royal Purple" for quite some time now.

I have used a 50/50 mix of ATF and Kerosene as a gun oil for years as suggested by C. E. "Ed" Harris along with his home mix ED's Red bore cleaner. Both has worked great for cleaning and lubricating handguns.

Dexron is a very good choice and priced much more reasonably. I have been using it to lube everything in my shop and it works great. I fill a small 4 oz. squeeze bottle and keep it on the bench. I never buy "designer" anything. They don't need to make THAT much profit. My experience has always been that oil works better than grease on firearms.

I've been using Ed's Red for cleaning and general CLP duties on frequently used handguns. I am a convert.

For those that sit for longer periods, I use Eezox.
Lubes from 60 degrees below zero (and will not thicken) to 700 degrees above (and will not liquify).
I am a bit skeptical about the claim of a grease that will not liquify at 700 degrees. I'd probably have to see that with my own eyes.

I can understand having to possibly shoot your gun at 30 degrees below but who shoots their gun at 700 degrees F?! :D

I have happily used BreakFree CLP or motor oil in a pinch (I use Mobil synthetic for my cars). I may try Ed's Red.

Stuff that is utilatarian, works, available in a 'handy size', and close to hand is what side arms are all about.

With that in mind and, if for no other reason than a handy size and a long successful history, the WW2 Garand Grease Pots work well. Like Hoppes Number 9, it does have a distinctive odor and works as designed.

Those pots are small, have a screw top, and were made to fit into the butt stock of a Garand. They don't leak in warm weather even when turned top-side-down or laid on their side.

Ambient? Nobody. Inside the gun or on the barrel? More.

I have some 'good' gun lube on hand (Ballistol & Beechwood Casey synthetic gun oil), but I got into a habit of using 10w-40 motorcycle oil or 15w-40 heavy duty engine oil in my oil drippers whatever is left over from oil changes on my motorcycle & scooter; so far none of the guns are complaining and I do not notice any increased wear or galling :)

I believe the man's question was...

Mobil 1 bearing grease for gun lube

--------------------------------------------------------------------------------

Has anyone ever used this for gun lube before? I heard about it on the Sig forum but I wanted to make sure that it would not cause problems with a polymer frame.

Yes, I have, and still do. Use it on everything that slides on all my guns, especially M1 Garand and M1 Carbines. Just a thin film is all it takes. One grease-gun tube should last forever, I transferred it all into a 3-cup Ziploc food storage tub. I also have a plastic syringe with a curved plastic tip from my dentist that he gave me for rinsing out the hole where he pulled a tooth....I filled that with the grease and it works wonderfully as a dispenser. Your dentist would probably give you one.

Where, may I ask, have you folks found Mob grease tubes?

How about Advance Auto Parts?

http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/product_synthetic-grease-mobil1_7070090-p?searchTerm=grease

I'd think just about any auto parts store would carry it.

I use Mystik JT-6 Hi-Temp bearing grease on the rails, Breakfree CLP on the rest of the gun. Friend of mine has a mechanic shop, he doesn't know anything about firearms but he gave me a 1lb canister of the stuff after I was asking him if he had any heavy duty grease that might be good for a gun.
http://docs.mystiklubes.com/msds_pi/M20026.pdf
It's cheaper than Mobil 1 grease when I looked it up, and according to their data sheet:
"...provide outstanding shock load protection. JT-6 Hi-Temp No. 2 is an extremely versatile performer that is highly recommended for disc brake wheel bearings... ...This grease provides excellent protection for heavily loaded industrial, mining, and construction applications."

I use Neco Moly-Slide. I had it sent to me by Bushmaster/Remington. It came in a little white jar, and I have never seen it for sale other than online, but it is good stuff. I have never seen anything "bond" to the metal as good as it. I have heard of people using Mobile 1 grease though.

I run an AR15 (CMMG.22) with nothing but a bit of Moly-Slide and it runs great..... It was the first AR I tried it on, and so far so good...

Have used 3 in 1 oil before. Haven't tried Dexron. Do use Ed's Red for cleaning. What's not to like about a cleaner that I can make, instead of buying.
Have thought about trying Lucas Oil Stabilizer.
Have used JT6.
Have some Moly/Graphite bearing grease I'm thinking about using.
Have also thought about using it and beeswax to make bullet lube.
