How much Marvel Mystery Oil per tank?
Seems like a lot of people recommend Marvel Mystery Oil but never say at what concentration.
So how much do you use? |

Re: How much Marvel Mystery Oil per tank?
I put in 8oz at every fill up, I put in an equal amount into the gas tank also.
Correction: I use a 4 oz. specimen cup, don't know where the 8 oz. came from. Note: Rinse cup "real good" before re-use

I got sold on MMO years ago, it does really help with today's dry gasoline. I don't think anything over 4 oz. per ten gallons will hurt a thing. I buy it in gallon jugs at WalMart, Farm and Fleet, Farm King, whoever has it on sale lasts all season.Good stuff. |

It seems that GM was tired of bad fuels leaving varnish deposits in the carbs, and then the cars being blamed for it. They wanted something that could be added to the fuel to keep the varnish from building up, and it had to burn 'smoke free'. MMO was born. Later on they found out that MMO had a great side effect; it was very good as an upper cylinder lubricant too. Much later they started recommending that you use it in your engine oil...but its unclear why. MMO has a unique ability to creep into very small spaces, much like the way Kroil does for penetrating and dissolving rust. This information was told to me in the pre-internet days by a MMO senior Marketing executive when I was researching inverse oilers. I use MMO in the fuel, and I've done so for decades. I use the product label as a guide: 4 oz MMO per 10 gallons fuel.

Re: How much Marvel Mystery Oil per tank?
Its best and highest purpose in my mind is to help prevent valves, lifters, and rings &c. from sticking due to soured or varnished fuel, sludge buildup etc. This is a real problem with collector cars and vintage iron that oftentimes sits for long periods. 4oz. Per 10 gallons in the fuel.

Re: How much Marvel Mystery Oil per tank?
I like it for freeing stuck engines. It's a good all around cleaner and lubricant, especially for things that have not been well lubricated and are out in the weather. It's a good upper cyl. lube. I have no problem with adding it to gas. However, I don't think it should be used in the oil, except on the last day or two before an oil change. MMO is basically a solvent for penetrating and cleaning things, not a lubricant. Yeah yeah I know I said it was a good lubricant for rusty stuff, not for engines running at 2500 rpm.

Re: How much Marvel Mystery Oil per tank?
Why not just run it on straight MMO?

Re: How much Marvel Mystery Oil per tank?
It’s a marvelous mystery how it works.
I know a guy that says it makes him regular so it must be good. It sure smells good. |

Re: How much Marvel Mystery Oil per tank?
The characteristic odor is Wintergreen oil, a very good penetrant. I knew a clock repair guy who used Mobil 1 mixed with MMO "just enough to make it pink" as clock oil. Not a big believer in Mechanic In A Can stuff generally speaking, but for certain applications it definitely has its place.

Re: How much Marvel Mystery Oil per tank?
I HAVE BEEN USING MMO SINCE 1960 IN MY OLD FORDS AND SOME OTHER BRANDS ON OCCASION. Works for me never experienced any sticking valves. My friend up the street from me, had a 9n tractor with sticking valves, he towed it to my work shop. After checking it over and finding stuck valves in two cylinders, I applied a liberal amount of MMO in the spark plug holes, put the rest in his gas tank and shortly thereafter the thing ran like it was supposed to. He is now a believer, comes with no draw backs as far as I'm
concerned.

I've eaten mashed potatoes twice a week for 42 years . Never had any sticky valves in my cars. Neither the Marvel Mystery Oil company nor the NTSB that investigated the cause of an airplane crash that they determined was due to the use of MMO, show any Wintergreen Oil in the product... https://en.wikipedia.org/wiki/Marvel_Mystery_Oil The Company's 2015 MSDS says it is composed of... -Petroleum Distillates (Hydrotreated Heavy Naphthenic) also known as mineral oil, 60-100% -Petroleum Distillates (Stoddard Solvent) also known as white spirit, 10-30% -Tricresyl phosphate, an antiwear and extreme pressure additive in lubricants 0.1-1.0% -Ortho Dichlorobenzene, a softening and removing agent for carbon-based contamination on metal surfaces, 0.1-1.0% -Para Dichlorobenzene, a precursor used in the production of chemically and thermally resistant polymers, <0.1% According to the NTSB, it is composed of... 74 percent mineral oil, 25 percent stoddard solvent, and 1 percent lard. If it works for you...great. But you might also try eating mashed potatoes instead.

Re: How much Marvel Mystery Oil per tank?
Well strictly speaking, what you say is true, if you want to look at it that way. The facts are though they found several empty gallon cans, the mix ratio must have been off the chart. Everyone always brings up that hoary old chestnut as if it has anything to do with the effectiveness or suitability for use by folks who know what they are doing. Its use for freeing or preventing sticky lifters, valves, rings is long known. MSDS isn't always complete btw, especially with proprietary information.

Re: How much Marvel Mystery Oil per tank?
From what I've heard about it, the FAA and the NTSB will automatically blame anything not "Stock" on a plane as the culprit in a crash if the pilot lives. If he dies, then it's "pilot error" or worse.

Re: How much Marvel Mystery Oil per tank?
We have BIG problems with ethanol in the fuel desolving varnish in the tank and sticking up the valves
MMO or ATF really helps with this We can not get ethanol free fuel Chris W. Last edited by CWPASADENA; 11-22-2017 at 02:36 PM. Reason: Typo |

Re: How much Marvel Mystery Oil per tank?
MMO and ATF look the same but are chemically different. How many times has MMO been accused of making a profit by rebottling ATF and adding wintergreen to cover the smell of it? MMO is a solvent while ATF is a lubricant. MMO was developed in 1923, ATF hit the market in 1937 with Buick's automatic Transmission. MMO and ATF will do pretty much the same jobs and about equally well in your upper cylinder. MMO just smells better!
