Marvel Mystery Oil vs Marvel Air Tool Oil 

The bottom line with this video and these two substances is this. No one person commenting here can PROVE what the components of each of these products contain. People say ' I hear it helps remove moisture from air tools'. Oh really? Who is to say that MMO doesn't do the exact same thing? Have you ever tried it in your pneumatic tool? Or used MMO in a pneumatic tool long enough to actually determine the effectiveness? Probably not. Manufacturers of products are required by law to provide SDS sheets disclosing the major components of the products they produce. So what is the magic part that 'removes' moisture? No one can PROVE what is in their gasoline, fuel additives, soap, kitchen cleaner, etc. So unless there are chemists here that do a detailed chemical analysis of what is in each of these products, what you all THINK is in there is irrelevant. I have used MMO in my glow engines for nearly 30 years and never has it damaged or not protected an engine of mine. That is good enough for me and I will continue to use it.

Nice gun Dave. You can never go wrong with a 1911.

I use MMO in my air tools for years. Not a problem. I just fill my old air tool oil bottles with mmo. Air tools work Good still and smells good while using. My oldest air tool is 10 years old. Still works. Thought I would just give my experience.

The Marvel Mystery Oil for air tools where I work is red and smells like regular Marvel Mystery Oil. So I always thought it was the same

Regular old Marvel Mystery oil seems to work just fine for me as well. It’s cheap and does the job. It’s like any oil discussion, everyone seems to have a different opinion and they will all argue with you why theirs is better many times just because that’s what they were told by someone’s friend who knew someone.

Interesting.. When my air tool oil bottle is empty I'm just gonna go to Walmart and buy the regular MMO and refill it. The bottle the air tool oil comes in is very handy!

Thanks for info! Brother gave me his trainer plane with an os 40 fp for Christmas, hasn't run for 20 years, all gummed up. Took it apart to clean and reassembled it using a bottle of gun oil I had handy. Hope I didn't screw it up.

Marvel air tool oil is great for air tools not so much for your eyes. I was putting on a set of brakes and just loaded the air impact with oil and blew it my eye I'm on day two after the incident and I'm experiencing irritation of the eye and sinuses. Has anyone else done this?

I've been told that air tool oil helps remove moisture from the tool. Thats a good thing for rc engines too. Most air compressors squeeze water out of the air and leaves it in the tool. As you know tank air compressors have a drain valve in the bottom to remove the water. That being said I use the good smelling stuff too. I don't know why. Just like the smell.

Your test showed 2 things: viscosity and color. By watching the flow test, they acted very similar. I bet the level of protection is the same. MMO vs MATO probably comes down to added dye and marketing. I bet they do the same thing. I've been a professional mechanic since 1999.

You think the air tool oil is good for leatherman multitools? I work at an O'Reilly and grabbed a bottle today but not sure if its what im looking for. I usually use 3 in 1 but leatherman says to use a teflon based oil..so im on the hunt. I have some Lucas extreme gun oil as well..what am I best off with?? Thanks

Probably just a dye to make it red.... Or the air oil is filtered better

In my personal experience regular mmo will swell certain rubber orings and completely destroy some rubbers but that's lesions learned in person experience with the original

I think it's entirely possible these oils are similar enough that the MSDS are the same. One could contact them to confirm.

I have always just used Hobbico HCAP3000 after run oil.

3:33 mins Oh yeah Regarding that oil you put on your 45, Is Hoppe's still around? I used to hunt and used their products and l always loved the smell of Hoppe's No 9

Man Dave! I just bought a 4oz. bottle of air tool oil at Menards for $1.68. I was actually going to mail it down to you until I checked Marvels MSDS info and found the flashpoint to be 128 deg. which is not legal to send thru the mail. I wonder if you might shake up your bottle and color check it again. My stuff comes out pink, smells ok but not as good as regular Mystery oil. The small 4 oz. bottle is very handy for my meager needs.

They can be the same base oil but add dye and a scent additive.

They can’t put the “mystery” ingredient on the MSDS sheet… duh! Laws be damned said marvel… hahaha Nice vid and humor brother. Oh and very nice how you go ahead and tell off the arm chair “experts” in the comments before they even get a chance
