Gun oil vs Motor Oil on your guns

I love Mobil one for pistol barrel and slide lubrication.

I know motor oil has a bunch of Different additives. My only concern would be if any of those could hurt finish either in the bluing or the wood (if applicable). But, give us a 6mo follow up!

I use Rem-Oil. It's everywhere and easy to pump from the bottle. Pretty heavy bodied.
I dare not say what I use for cleaning.

Where things swivel or on pinned joints where there isn’t any heat I use a 100% silicon lube that’s actually for a treadmill. For the inside of the barrel and all exterior surfaces I use BreakFree and on sliding surfaces like semi-autos and action slides (pumps) on shotguns I use this stuff called STOS, stands for “Slicker Than Owl Sh**”. Invented by a couple of trap/skeet shooters for screw chokes. A little bit goes a long way and I’m sure the small jar I have will last my lifetime.

Breakfree CLP. The military has been using it for 4 decades. Its a high performer in all catagories. Not the best. But it is consistant across the board. Some oils that tought this that and the other will perform great on one or two catagories such as friction tests and wear tests but will totally fail in freezing temps and other catagories.

Breakfree CLP does NOT do all 3 well ,,project farm tested a bunch of products that claimed to do every thing ,and none did all very well,, including Breakfree CLP...best to get a good cleaner, and then a good lube /protector.

I have seen owl sh** and where that term comes from i have no idea as that stuff is crunchy and got bones in it.
Probably the least slick SH** I have ever seen.

Not saying the lube is bad though

I started using 0-20 full synthetic motor oil on my firearms in place of Lucas Gun Oil. I haven't noticed any issues so far.

The argument that got me to switch was that if I trust the motor oil for thousands or revolutions per minute in a machine that costs thousands of dollars why wouldn't it be good enough for my guns that only have to endure at most hundreds of cycles a day and cost just hundreds of dollars.

The conditions found in a firearm seems much less demanding that the conditions found in the block of an engine. I know there is a lot of slick marketing behind really expensive gun oils. Also to my knowledge there is no third party agency that establishes minimum standards for gun oil as the API, ILSAC does for motor oil.

I'm curious what you all think of this topic.

Here's what I use on ARs.



There are a ton of different lubes you can use on handguns.

I think the only drawback I've seen mentioned with regards to using motor oil is the lack of corrosion additives.

I’ve run Mobile One 5w-30 synthetic on pistols and AR-15 bcg’s for years.

I disagree, lubes are tested with 7 catagories and CLP Breakfree performs well to adiquate in all 7.
