Holy buckets of @#$^ - 30,000 rpm my gosh!!!!!! What would that look like looking at the piston move? Would it be a blur or look like it's not moving, maybe invisible!!! 50,000 redline - beam me up /forums/images/graemlins/crazy.gif

Yeah, I was thinking the same thing. I wonder if those babies ever come apart? I'll bet it's impressive if they do. /forums/images/graemlins/shocked.gif

I have .40 size model airplane racing engines that variously turn between 19,000 and 27,000/30,000 RPM but I never seen anything do 50,000 and I been playing with model airplanes since I was 5 years old, control line, RC, free flight and gliders. Anyways, some of these run on 70 percent nitro /forums/images/graemlins/shocked.gif--open exhaust. If that is true, that is impressive /forums/images/graemlins/shocked.gif /forums/images/graemlins/shocked.gif /forums/images/graemlins/crazy.gif. Don't know much about the RC car scene but using MMO as an after run oil is common pratice with glow engines. Some pumper engines it will destroy the seals because the seals are designed for methonal and not a petroleum product therefore there are specific after run oils for such engines--YS Engines comes to mind and they recommend a product from Performace Specialties that contains no petroleum.

Years ago a buddy had a Datsun 510 with high mileage and started using oil. We put in a quart of motor flush (Gunk I think?) ran it for 15-20 minutes then changed oil and filter. All kinds of crud came out. Fresh oil and filter drove like new and took him on through college for several years. Just a thought. Daveh1 Mits D-2050 Honda rancher /forums/images/graemlins/cool.gif

I am just commenting on my experiences with Marvel Mystery oil for air tools. DO NOT USE IT. I had been for the last year or so and it rotted the nylon valves in my CH butterfly air impact to broken hard little bits /forums/images/graemlins/frown.gif
Just my experiencs though, and you might not have the same results on all air tools.

Ben, I replaced a lot of those valves that had disintegrated in various brands of air tools when I was in the business of repairing them. Of course, I never knew what kind, or brand, of oil the customers were using. However, I've talked to several people who used the regular Marvel Mystery Oil with no complaints about it. And not being a chemist, I don't know just what the difference is (except color /forums/images/graemlins/tongue.gif), but you know they also make a Marvel Mystery Air Tool Oil specifically for the air tools and that's what I used all the time. It's clear instead of red and comes in a white can instead of red. At least that is, if you buy it by the quart like I did. /forums/images/graemlins/laugh.gif

I just ran across this thread and wanted to relate my Marvel oil story. I have been a pilot for 25 years now. One of my airplane was a Stinson 108-2 with a 165 h.p. motor. It was having morning sickness everytime i started it. (valve sticking when cold). A few month prior to my engine trouble a fellow pilot bought a Stinson that had sat for quit some time. The compression was low on 2 cylinders. His solution was to put 8 quarts oil and one quart marvel in and a few ounces in the gas, run it untill the temp came up high. Climb hard and fast a few times. Change oil and marvel and do it once again. Valves no longer stuck and rings came free. Result, good compression and low oil consumption. As far as my plane went. I put a quart in the oil and a few onces in the gas. From the very first start after that my valve trouble went away for good. I tested it afterward with no oil in the fuel and am absolutely convinced i needed to run Marvel in the fuel and oil from then on. Years afterward the plane still flyes well.
Just a month ago i put marvel in my chevy truck oil and fuel. I have 150k miles on it. The valves are cleaner, (I removed the valve cover to look). Needed new gasket anyway. I wont say it runs alot better but it does run smoother due to cleaner injectors i'm sure. I would have put Marvel in from new if i had purchased it new.
There is an oil on the market that is certified for aircraft use called "Lenkite" I read an article from the guy who had used it for car racing for years. Bottom line it is Marvel Mytery oil without the dye or perfume. He related marvel oil to highly refined sewing machine oil. There is and aviation training school that uses Lenkite, because it is certified. They claim to have reduced there valve sticking trouble by 80 percent plus. I will try to find the article and pass it on sometime. There is also an article about a helicopter company using the oil and going way past TBO in there testing of Lenkite.
PS I hope i spelled Lenkite correctly.

Greg, when I was teenager and my Dad owned a service station, we had one customer who had about a 6 year old Ford sedan with lots of miles on it, but he kept it looking and running like new. And when we changed the oil in it, he wanted Texaco non-detergent oil with a pint of Marvel Mystery Oil. I reckon that gave him a pretty high detergent oil and he said he'd been doing that from the time the car was new.

Dad later sold that Texaco station in Oklahoma and bought a Mobil station in Texas, and opened an auto parts store, so we sold lots of Marvel Mystery Oil back in the late '50s.

You can get the same results cheaper by using straight mineral spirits, since that is mostly what MMO really is.

Take a look at the first page of the thread and I posted a link (sorry, it's now broken) to a DOD Hazardous Materials Data Sheet that described just what is actually in MMO. It's mostly mineral spirits, chlorinated hydrocarbons, and napthenic hydrocarbons.

It has oil of wintergreen also; a natural but effective cleaner.
The military used Marvel oil during WWII in aircraft engines.
Snake oil?? I don't think so. People say it's the same as ATF.
It's NOT the same as ATF.

It's great for lubing valve guides and upper cylinders. It keeps gasoline fresh during storage. Gently cleans fuel systems and keeps them clean. I only add it to fuel. I wouldn't add it to crankcase oil regularly unless the engine had stuck rings or something.
