Didnt want to hijack Whiskers thread.

Lots of people say they use Mobil1 for a gun lube.

My question is are you really that brand loyal or is it just easier than saying automotive oil?

You convinced me a long while to use auto oil but I dont use Mobil1 (I have the poors) my bottle has the dregs of whatever oil I found on sale.

I use Mobil 1 Synthetic. Like actual Mobil 1 Synthetic. As for weight I just use whatever is on hand. I think I'm currently using 10w30.

I use Mobil 1 because it is good stuff.
That's just me. You do what you want.

As long as it’s synthetic I don’t see what difference it would make.

It doesn't do much to prevent rust, so that is why I'm not all for it.

I use Mobil1 in both Jeeps and the Harley. I tend to have plenty left over for my guns.

Any oil will work in the guns, but it's what's here

I use M1 in my vehicles because it is the cheapest oil I trust.  Also, the M1 25w50 does not have friction modifiers and can be used in bikes.

I use it in my guns because I have leftovers.

I would not hesitate to use any decent motor oil, including Dyno oil on a gun.

My gun lube is motor oil with some Hoppes #9, WD-40 and STP.

The STP thickens it up and the WD-40 helps as a rust inhibitor.

Always has worked fine.

Saying Mobil 1 is like saying Q-tip, Band-aid or Vaseline.

I've been using whatever Great Value WalMart brand full synthetic 5w20 I use in my car. No issues. This ain't rocket science.

I've had issues with "gun oil". Had a few brands dry up and go gummy on me, or the opposite- too thin, and it'd just disappear after you shoot a few rounds.

And for rust, I use another automotive product. Fluid Film. Spray on a microfiber cloth and wipe down. Even keeps my Remington 870 express with the 80 grit finish from rusting

I use Penzoil because it smells kinda like maple syrup. Plus its all I use in all my cars. Mobile smells to much like petroleum plus my cars seems to run/idle louder when using it. Haven't used Mobile 1 in over 20 yrs.

I read something awhile back that recommended ATF due to it's shear resistance.  I'm not a chemist, but it sounded good.

Probably this.

I've always considered Mobile 1 "the best".  May no longer be.  Maybe never was.

I don't use it in my car

But compared to the price of CLP, I consider Mobile 1 a steal so I use it on my guns.
Link Posted: 7/20/2021 9:03:41 PM EDT
Cheaper than "gun oil" per oz and Mobil 1 is just the first oil I have tried. Still have the first quart.

Cherry balmz master race checking in. Honestly I don’t know if I’ll like it long term for an AR. I have had zero issues using regular CLP.

I will say the CB rimfire remedy is no joke and I took a MK4 to 1000 rounds with no cleaning or additional lube with very few issues shooting 100% suppressed. Previously it would start acting up after 250-300 rounds with the can

I don’t shoot my EBR’s nearly enough for any lube to make a difference. They get 100-200 rounds and then cleaned and re lubed.

What oil does your truck take?

Great. That’s what your guns use too!

Motor oil works just fine as a CLP. Which I use depends literally on what is closer when I need it. I don’t keep motor oil in a squirt bottle, so dispensing if is sometimes annoying. Usually dip qtips into the bottle or get some on a rag for wiping with the motor oil.

I don’t see you being able to tell the difference in oils in mild conditions. Maybe in extreme heat or cold some 15-40 or 5-20 might show some better results. I don’t think any modern firearm has tight enough tolerances or harsh enough operating conditions for you to tell the difference at 500 or 1krds. Maybe when you get up to end of service life, like Henderson Defense or some high volume match shooters do, but a regular shooter would never be able to justify an argument that one grade of oil actually helped that much. I’d think that over a 50k life, one brand to another might only be +/-2k. At which point, there’s so many other factors that may have contributed, the argument is null anyway.

You’d really need some testing equipment like the DOD has, and be able to use consecutive serial number guns with same lot ammo. I don’t personally know anyone that can afford the time, space, or money to perform a legitimate test like that.

I run mobil1 in our trucks. It’s actually not that bad if you go to Sam’s. The part that sucks is they sell it in 6 packs of quarts. Iirc it’s $27 for the box. The boxes do stack on the shelf better than jugs I suppose, and I’ll usually buy 18-24qts when I’m there.

And always use motocraft and toyota filters for the girls.

ETA: I see mention of WD40. For what it’s worth, IMO, it has two uses for the firearms enthusiast. One, to displace water after a rainy hunt or the like, and two, to dissolve plastic fouling from a shotgun bore. I grab the stuff every time I clean my shotguns, makes the bores sparkle in no time. I do remove it after cleaning, with a couple dry patches, and chase with a couple moistened in whichever oil is handy.

I blend mine with some atf fluid, it adds rust preventative.
Link Posted: 7/20/2021 9:47:20 PM EDT
Just buy a quart if you don’t use it...  not exactly expensive.  I put it in an armory for duty rifle lube and they are probably still on the original quart.  

You only want it on the AR internals.  Mobil 1 is semi worthless on the exterior for rust prevention.  Stick with Breakfree CLP or another good rust preventative for that.  

I found it works great on the AR as it does not burn off on the BCG and barrel lugs.  

Not sure it is any kind of an improvement in other guns, for sure see zero improvement in pistols using it.  The AR getting hot gases inside the action is why Mobil 1 and similar synthetics are great.

You just need to change it every 5000 miles or so.

Been using it for many years.

When I need oil I use only Amsoil Synthetic, but I don’t use automotive oil on guns. I still use Breakfree for that.

I swear by MPro 7x's lube. I was in an Urban Rifle course last week and ran my own little experiment with it.

Class was 3 days long, I started out with a very generous amount of lube. Shot about 300rds that first day. Second day, bolt and BCG were still looking wet, and shot approximately 300 more rounds.  The final day, about half way through, I started having mafunctions. The BCG was relatively dry, it needed lube.

Now, I will say this, the ambient temp was 100 and my rifle was getting fucking hot. The last day of the class, I had some color change in the barrel.

I added lube, and back to running like a top.

In past experiences, the 7x has treated me well, and I really like the product.  It would stand to reason that something that is more viscous would last longer, but the heat generated by firing so many rounds in rapid succession does some crazy stuff to these rifles.

If your gun won’t run when lubed with oil scavenged from cars and trucks 10 years after the supply chain is fully broken, it’s your funeral.


Link Posted: 7/20/2021 9:58:02 PM EDT
A quart of Mobil 1 lasts a long time but what is really important is the full synthetic nature of the oil as it doesn’t break down like the old cheap stuff.

I pour the dregs from each 5qt jug into a bottle. As in, I let the 5qt jug drip into a container when done dumping it in an engine.

So far, I'm up to a quart of Mobil 1, Castrol Magnatec, Quaker State whatever, 5w20, 5w30, mix. It works!

I use Aeroshell. Equivalent to SAE 40, no additives like automotive oil, and formulated for high temperature air cooled aluminum engines. Was given a case in paper cans (FAA don’t like paper can oil nowadays), and figure six gallons will be a lifetime of gun oil for a few generations.

Plus it sticks to cycling parts well without being grease.

For the curious:

I use mobile one because I typically have to change the oil in my truck every one or two months.  Nice way to use the excess. I need at least 13 quarts per change so the extra from the three 5quart jugs lubes the rest of my world.
