It helps some. Most rotorheads use it for additional lube (aka premix).

How many more people are going to post "their opinion" that this crap is a good lubricant?

It's basically a solvent, and absolutely no use as a lubricant - in fact it has been shown to make wear WORSE.

http://dieselplace.com/forum/showthread.php?t=177728 this study is just the latest - it shows MMO to be a worse lube than used oil, two stroke and most other additives.

In the test rig, the fuel with the MMO had much worse wear than the control sample that had NO additives!

Don't put it in your RENESIS.

I use SeaFoam, which is also an engine cleaner, in things like my mower, my snowblower and other small engines - clears the carbs of crap.

Is the RENESIS a diesel? If not I don't see how that applies.

MMO may be less lubricating than diesel but more lubricating than gas which is also a solvent.

I've read through several of these premix threads and nobody seems to agree on anything.

my 1949 packard has a packard dealer installed marval mystery oil injector. this was a very popular thing. it helped lube the valve seats it cleaned the combustion area and was a very good product on the old packards. there was no thought of a wankle engine when mystery oil was first produced, I think you would be takeing a risk.no one knows what it may do to the rotor tips and other parts. marvel has a web site and they are very helpful people. I suggest you check with them. good luck

If you are looking for a lubricant (which we are, in this context) you wouldn't use diesel, so why even suggest something with CONFIRMED PITFUL lubricity?!*?

Oh, what do I care, use whatever Granpappy used in his Edsel.......

I don't think it is confirmed pitful. It is confirmed to be worse than diesel. How do you think straight gas would have done to their study?

Maybe I would use diesel. A little B100 is over 2x better than than the Super Tech 2 stroke oil. It might acutaly be a good choice for a pre-mix.

MMO has other properties that make it a possible good additive.

That thread also recommends pre-mixing although some still are against it.

Just looking for some answers. My thought was to run a gallon of MMO through my RENESIS with 36K on it - 4oz at a time to clean up any carbon deposits and see what it does for fuel mileage. I really don't think it will hurt anything and it does have more lubricity than gas.

BTW, thanks for the link to the diesel place study. My other vehicle is a Duramax and I may start looking for some bio fuel to add to it. I have found that the MPG goes up on biodiesel (when I can find it) under light loading. Hauling it goes down.

I'll never trust any product with both "Marvel" and "Mystery" in its name.

As for MMO, just use it quaterly to clean or clear out carbon dispots/ ash buildup , just know to ride the car hard while the pre-mix is in the tank... then add a two-stroke lube if you want...least for the next two or three fill-ups....

Doctorr

MMO may be useful for dissolving some of the carbon, but please don't get it confused with a lubricant - it ain't.

my 49 packard 22nd series has a marvel mystery oil injector.

ive been using this stuff since i got my car. i premix in 4oz every fillup. So far the car runs great and i get around 17.5 mpg with almost all hard city driving.

Well im a little confused now as when i read the premix thread many say to use MMO, however it seems to be the opposite in this thread.

Razz1

Yes, I noticed that.

My concern is carbon build up at the Apex seals, and the fact this is claimed to be a lubricant.

What we need is something that burns readily. I know it works on Harleys.

peterlemonjello

The MMO debate/discussion/argument has really taken a life of it's own. Premixing is controversial enough. I can't foresee any type of agreement on what to premix with.

robrecht

Part of the explanation is that this is an old thread that has been resurrected. There was a time here when hardly anyone here saw a need for premixing with their RX-8s, let along premixing with MMO, which has been popular among older rotorheads for a while. Once the 2009 RX-8 engine changes started to become public, a lot more people were convinced of the wisdom of premix. As far as MMO is concerned, read Jax's posts in the linked thread and elsewhere if you want to get a fair view of why he became a specific proponent of MMO. He seems to know what he's talking about when he defends the lubricating benefits of MMO.

^^^^^

that is a very good observation about the the past 4 years of my life. the info that jax provided was very useful..

Lol, I was convinced too...

I'm gonna pass on a product that's as old as MMO, although I heard it's a good top cylinder lubricant for diesels. Perhaps a bio diesel conversion is in your future.
