Default Gun Oil Test

I'm going to say up front that this probably isn't 100% scientific in nature, so don't criticize my methods unless you go out and do it yourself.

I wanted to test a couple of things to see how they do in resisting rust. I live within earshot of the beach, and things rust around here really easy. It requires constant vigilance to make sure my firearms stay rust free.

Prep: I took 4 nails and cleaned them up on my sander to make sure all rust preventative from the factory was ground away and I had bare metal to start with. You will notice from the pictures that only about 1 1/2" is the part that I ground down. Had to have something to hold onto and not burn my fingers! I then sprayed them off with brake cleaner and wiped them all down with a paper towel. I used surgical gloves throughout to prevent oils from my hands from contacting the metal.

Contestants: 1 nail is control and has nothing on it. A shovel left out overnight here will be really rusted by morning, so I anticipate this nail will be really rusted in the morning. The others have one of these 3 oils on them:



Initial photo: From left to right: Royal Purple, Rem Oil, bare nail turned 180 degrees from the other 3, and the right one is DuraLube.



I am going to try and remember to take a picture first thing in the morning as light allows. Tonight's picture was taken at 4:05pm.

Who is betting on which one of these 3 products to provide the best rust prevention? I can tell you that the DuraLube by far felt the slipperiest in my fingers when I was applying the products.

Thoughts?

I think duralube will have the least because the viscosity is higher and will protect the nail longer, versus the other two “lighter” gun oils...

Excellent point. When I sprayed the Royal Purple, it built up on the nail and I had to shake off the excess. The Rem Oil was so light, it was almost like water and there was nothing to shake off. The DuraLube was certainly the thickest and required the most shaking to get rid of the excess. However, the DuraLube and the Royal Purple weren't that far apart it seems like.

So, viscosity plays into rust prevention? Interesting.

Well, I would are argue that the viscosity will affect how well the trial area remains protected.

If the oil runs off, or evaporates, or otherwise disappears to quickly it will leave an unprotected area open for rust...

No feeling either way, this will be interesting.

IBTFLFB take over...

I’ve seen other tests like the one Choprzrul is doing.
Last one I saw put WD40 as one of the top winners, can’t find the thread in my bookmarks though.

Here are some other tests:

Of course, these types of tests have been done before---the last one I read about (several years ago) showed the winner as Breakfree CLP---thats what I have been using for the last 20+ years (maybe longer) and all weapons run just fine and NO RUST!

Part of the fun of owning firearms and cleaning them is the endless search for something better to use. Trying new things. Same thing with car wax. Who does not have a cupboard full of half empty bottles of wax?

Tagged,

and also, I have yet to see anybody else use the same lubes that I do. I'm tempted to do a test of my own, as I would definitely put them up against FL or any other lube. I use these lubes daily in the dairy industry, where all of the equipment is cleaned with a caustic chlorine solution, followed by a heavy acid cleaner every 12 hrs. This same equipment is also subject to being covered in cow crap and pee and water all day long.

I use Fluid-film spray, it's amazing. It works great on my guns, but I also spray down my jet-ski engines with it. After 20 years of running in the ocean, the engines look brand new, with just a rinse and re-spray after each trip.

Fluid-Film

Secondly, I use LubriFilm grease. This stuff is the slipperiest grease I have ever found, and it stays slippery when its hot, freezing, wet, covered in crap, etc... Very good stuff.

LubriFilm

Corrosion X is an xlint product. Ran 2 different boats in salt water for over 8 years. One boat was outboards the other twin diesels. Hose the engines down with fresh water after use and spray with Corrosion X. Not to mention all the exposed electrical terminals. No corrosion or rust.

Take it from me, for what is designed for it works!!

That is an excellent write up. I am curious how the Royal Purple would have compared to the others in that test.

9:00am.

Went out this morning to check. A close visual inspection showed that none of the 3 with oil on them had any rust at all. The control nail has quite a bit of rust on it. Keeping them in order, I moved them to a clean paper towel, and then placed them on a second paper towel on the same board that I had them on last night. The white gives better contrast so that you can see the rust.

I went back out and looked at them again a little bit ago. In prepping the nails, I had initially taken some fine sandpaper and scrubbed the nails in an attempt to remove the protective coating on them. You can see some gray above the ground area in the pictures. Above the gray area right at the nail's heads, none of the protective finish has been touched. I am really glad that I used the bench sander to get down to bare metal as that factory coating looks like some thick and tough stuff.

The nail with the DuraLube on it seems to have grayed ever so slightly. I suspect that the oil itself changed the color of the metal. This is a very slight color change and in no way looks like rust.

I like and use Eezox myself. Haven't had any rust on my guns. There has been numerous Test's on different oils.

12/27/11 @ 3pm

Been a week now and here are my observations:

Royal Purple: Zero rust noted

Rem Oil: Heavy surface rust with some deeper rust noted

Control: Heavily rusted

DuraLube: Several spots of surface rust developing, but not much.

Here is the picture from this afternoon:



Has anyone else seen any other tests with the Royal Purple Gun Oil? I am now wondering how it compares in both rust prevention and lubricity to Eezox. I have read that Eezox is really smelly, but the Royal Purple isn't bad at all. I am anxious to see what another week does to the nails.

Thoughts at the 1 week point?

Bummer,

I had hoped my prediction of DuraLube would have been ace, alas I am incorrect...

It’s nice to see royal purple gun oil holding up well!

I am surprised that the DuraLube didn't protect longer. Like you, I thought the higher viscosity would have kept more of the product in place to provide protection.

I am really surprised that the Rem Oil didn't provide better rust protection. I think that I am going to throw that can away....
