Marvel Mystry Oil

[CurtG]

I've been reading through several of the fuel and oil threads and I've found that it doesn't seem to mater which bike it is almost any brand has its champions and its detractors about evenly split. Although I've noticed sometime if you ask 2 people you can get 3 answers .

As some of you may know the wife drives a 2013 Ural Tourist and the one thing that I find almost universally recommended as a fuel additive over on the Soviet Steeds forums is Marvel Mystery Oil. Now I realize that other than being 4 stroke and and mounted in motorcycles the two engines have very little in common. Not the least of which is probably close to 60 years difference in design and engineering.

That said has anyone ever tried MMO in their Spyder's fuel instead of Stabil or Star Tron. Not sure I've ever seen Star Tron on the shelves around here. Who makes it? I've generally put an ounce or so of Stabil in the tank when I fill up. We tend to go through spells of either cold and damp or hot and humid and I figure it might slow down fuel problems particularly in the winter when the bikes might sit for a few weeks.

Spring is upon us, ride safe gang

I've used MMO in cars and trucks but have not used in my Spyder. Should work well tho.

MMO is needed by some ancient engine designs to help lubricate the valve stems and guides. The Spyder engine is not a 1930s design, like the Ural. The Marvel Mystery Oil will only cause fuel octane degradation and possible spark plug fouling. Save it for use in your air tools.

Rislone and Marvel M Oil were a good product for the 50's 60's engines, I would think that they changed their formula to meet the demands of the newer engines. That said i only use Star- Tron, or Stabil In the GAS tank.
I don't use any type of oil additive in the CRANKECASE, Modern engines don't need any, And all manufacturers recommend Not to use any also!....

Marvel Mystery Oil

​I can remember my Dad using to keep the valve guides lubricated in the family Plymouth sedan with a flat head six in it. He used to say it was the cure for poor designers ....

I have used MMO oil in the gas of my small engines for longer than I care to remember. While I do not use it every tank on my BMW 1150 RT which has a cat, I do use it several times a year and have never seen a sign of any ill effects. I particularly like it for its cleaning effects. I also seem to notice an improvement with this garbage ethanol gas our elected idiots force down our throats.

I usually use it along with the appropriate stabilizer in my fuels depending whether I can get non ethanol fuel or not. What I can say for certain is that since doing this I have not had any gummed up fuel systems, so IMHO, it is an advantage.

As always. I swim upstream. Have been adding 2 ounces of MMO at every fill up for over 10,000 miles, without a sign of trouble. If you decide to use MMO here's a tip. Buy 'lab quality' 2 oz. bottles from the Container store. They are designed to seal well and the MMO will not harm the plastic. I keep full ones in one zip lock(just in case one leaks) and the empty's in a separate zip bag.

~~~~~~~~~ < that's just how I swim:roflblack:

 

[Chupaca]

Have to agree..!!

Not in my spyder although I do use Seafoam for the gas and has been working well. Was recommended here..!!hyea:

Memories

Now that brings back pleasant memories. I used a lot of the MMO in my 1958 MGA Roadster. It took care of the tic,tic,tic really quickly. Gosh I loved that little car!

MMO in the oil. Yes?


Folks, never, ever, add MMO to the oil of your Spyder. nojoke

 

[beanoil]

I run MMO every tank in everything I own. I especially like it in carbureted engines, but have found that fuel injectors benefit over the long term with much less wear on the pintle. 4 ounces for every 10 gallons. I carry a 8 ounce squirt bottle on the Spyder and add about 2 ounces every time I fill up.

 

[MouthPiece]

It smells good.

Perhaps it could be used as cologne? :yikes:

By volume it would be far less expensive and most biker chicks would love it :joke:

Marvel Mystery Oil is no longer a mystery. It is simply Chlorinated Hydrocarbons, Mineral Spirits, and Naphthenic Hydrocarbons. Translation, it is a typical petroleum based solvent. Some believe it also contains oil of wintergreen to make it smell pleasant. It's a decent if somewhat hazardous solvent and could be used to clean parts or as a carburetor cleaner. Is it good as a fuel system cleaner? Maybe back in 1930 it was, but there are far better formulations now such as Techron. Is it good as a gas stabilizer? Maybe if you lived in Siberia and couldn't get better products such as Star Tron or Stabil. Should you add it to oil? Not if you want to keep the properties of the high tech synthetic oil that you paid so dearly for.

You can file Marvel Mystery Oil in your woefully outdated products catalog along with Seafoam and Slick 50. They continue to sell because people keep them alive by word of mouth so why should the manufacturers stop selling them?

If added to Spyder oil it will also destroy the clutch. nojoke

 

[flybuddy]

No no in the Rotax but works well in many aircraft piston engines which are 40s technology and still use highly leaded fuels. I've seen zero compression cylinders brought back to life in both Lycomings and Continentals by filling with MMO and let sit. Good solvent.

SEAFOAM is a great cleaner for one-time use but since it has alcohol content, it may not be appropriate to use regularly with Ethanol fuels.

MARVEL MYSTERY OIL is an amazing product from the past... I used it in the early '60s to clean out auto Carbs, but I would hesitate to use it on my Spyder and there are proven products available for modern day fuels & engines.

For sure I am not a fuel systems engineer, but if you do some searches on this site you will find an amazing amount of data and studies about fuel and additives appropriate for todays fuels & engines... Read the facts !

Yanmar

I use mmo in the engine on my boat both in the crank case and fuel. It solved the problem I had with a lazy ring 3 years ago. My engine is a 1987 Yanmar. I would not use in the Spyder.

 

[redflasher]

I use it for my guns but no longer use it in any of my vehicles.

I agree!

New engine designs along with new mfg process demanded a lubricant "designed" to meet those demands.

MMO met the "old needs" but is not now designed for use in these new hi-tech engines! Same logic applies to using leaded gasoline (if it still existed) to lube valve guides.
