I've heard about using MMO as a premix but what about adding it to the engine oil. Any benefits or harmful effects?

No.

anything info/proof to back that up.

It's a thinner oil, so you will have reduced viscosity...which is bad. It's actually a pretty good solvent, which might more useful for loosening up stick lifters or removing sludge in a piston engine, but not so much on a rotary. My $0.02

The fact is that motor oil has been developed and designed for decades. It's good. If you have an oil system problem that is related to the oil, the solution lies in changing motor oil types, not some additive.

MMO is an all-purpose solvent and oil, and adding it to motor oil will not improve motor oil's performance as either a coolant or lubricant. You might argue it would help because it has additional detergent properties, but with an FD you should be changing your oil often enough that the oil passages never get dirty.

As much as it would be convenient to make me provide evidence that it *doesn't* help, the real question is proving that it *does* help.

Marvel Mystery Oil is God's Own Creation and univerally accepted as the 8th Wonder of the World! There is nothing, and I mean NOTHING that is not enhanced by MMO.

In addition to a 1001 uses in the automotive and marine world, it makes a helluva steak sauce and serves as a wonderful sex lube.

With that in mind, I bought a few bottles on sale at WALMART and added it during fill up at the rate of 4 to 6 oz. to a tank for about a year and a half. But NOT as a premix. My hope was to reduce carbon buildup on a strictly streeted engine.
Anecdotally, they did seem cleaner, with less carbon. But who knows. YRMV
They also claim that it's a fuel system "lubricant" (not a cleaner), whatever that means.

There isn't any reason to "add" anything to your motor oil. Short of avoiding the latest API "fuel efficient" motor oils (it's been brought up that the lower amounts of anti-wear additives can possibly be harmful in the long term, but the jury's still out on that one in my opinion), any quality name brand has all you need. There's no reason to try and play oil chemist with your oil.

All quality motor oils have more than enough detergent properties, either through additives or their own chemical makeup.

I believe there's a MSDS on MMO, and its mineral spirits and I think Stoddard or Naptha solvent.

bajaman

No ****? So one could distill it into crude napalm then.....sweeeeeeeeeet! (although mothballs and gasoline work much better......)

The uses for MMO just NEVER quit popping up!

Seriously, I've used MMO in about 23 different vehicles over the past 30 years I've owned cars, torn down some of those engines and they always look MUCH cleaner than what they should for the mileage some have had.

....try adding it to your gas, on a fuel injected car that's starting to run sluggish...it might amaze you. ...but I would NOT substitute it for premix.

FDse7en

iTrader: (3)

why wouldnt it be a good substitute for premix?

Ledfoot

iTrader: (1)

...well without even comparing technical data...simply consider marketing.
..no where will you find "premix" mentioned in any Marvel Mystery Oil advertisement, not even on their container or website. http://www.marvelmysteryoil.com/
as a fuel additive, "lubricates, valves, rings and upper cylinder walls" is mentioned on the container as its strongpoint as a fuel additive.

...maybe MMO is better as a premix than engine oil...I believe it's more combustible that engine oil, and cooked engine oil obviously gums up....my guess is that the OMP using the engine oil was developed to keep the average person from being scared off with the possibility of having to regularly add oil to their gas or some container under the hood.

... key selling points mentioned for premix and injected oils are "anti-scuffing" , "resistance to high heat, high pressure breakdown" and "low ash content" ...I believe "flash point" as well...you will not find any of these characteristics associated with MMO in any of their advertisements.

I also think some people associate MMO characteristics as an oil additive with it's characteristics as a fuel additive, but that still doesn't add up to promote it as a premix....besides....some of what are considered to be the best premix and injected oils are cheaper than MMO...not to mention the fact that they were designed specifically for the purpose and with 21st century technology...

While the name of the product has "oil" in it, it is predominately a SOLVENT.

It's primary use is to CLEAN away varnish, and gummed up parts, including fuel-injectors.

That objective is in direct competition of a pre-mix, let alone the OMP system, which is to LUBRICATE the combustion chamber seals.

In short, you will be diluting the lubrication qualities of your fuel and lessen the effectiveness of the OMP.

If you are having injector issues, either pull them and have them professionally cleaned, or run a high-concentration of Chevron Techron of RedLine Fuel system cleaner.

Note, even on the bottle of the Techron it recommends only ONE BOTTLE per engine oil change interval. Again this is due to it being a SOLVENT.

As someone mentioned, use High quality detergent oils, and change it often, and your engine internals should be clean-clean-clean. Mobil 1 over a course of a year, will also clean out your engine.

Combine short engine oil intervals, use quality fuel, frequent fuel-filter changes, and a maintenance dose of RedLine, Techron, or even MMO as FUEL-SYSTEM CLEANER ONLY, will keep both the engine and fuel system internals clean and varnish, gum free.

I would NOT use MMO regurlarly let alone as a pre-mix.

so is there a consensus that if your omp is operating correctly you shouldn't premix?

i use MMO as a solvent at oil change intervals. i put it in the oil, drive it around the block to get it warmed up, then i change it out. dont know if it helps, but i figure it cant hurt in that application.

as stated, i would NOT use MMO as the soul premix agent. it simply isnt meant for that. ive been using a 2stroke OMP adapter for a couple years now, with no ill effects. . . though, i havent cracked the engine open yet. time will tell, i guess.

I think I know what your getting at, but I never really thought that fuel has much in the way of lubricating qualities. And I'm not seeing MMO lessening the lubricating effects of the OMP anymore than the fuel itself.

i run mobil 1 in my engine..mainly for extra turbo protection and heat reduction. I have heard much criticism for using mobil. Many say that it will build up a film in the engine which is bad for rotary. So, everyime i fill up the tank i premix 4oz of MMO (yes every time i fill up) to help in blowing out the film left behind by the mobil 1. I don't see how this could possibly hurt the engine.

It isn't necessary. But you can do it if you want.

M104-AMG was making the point that if you're going to premix, MMO is not a good choice. And that if you have a working OMP system, MMO premixed in the fuel will reduce the effectiveness of the injected oil.

Baja, personally I think there is a tradeoff between mechanical wear and cleaner internals if you use MMO, vs a little more (maybe) gunk in the engine and less mechanical wear.

You can always clean off varnish and carbon. You can't put back metal.

I don't think it's a good choice for a pre-mix meant to substitute an OMP, but to say that it makes the OMP less effective makes absolutely no sense to me.

I'm with Sgtblue, mix a bit of gas and oil together and you will have an ineffective lubricant, MMO or not...

M104-AMG

Mixing gasoline & MMO is mixing one solvent with another.

Mixing gasoline with let's say ash-less 2-cycle oil, will be more of a lubricant than the other.

:-) neil

poss

iTrader: (5)

Agreed and I probably should've specified engine oil.

I think your statements earlier were interpreted that adding MMO to your fuel would cause all the oil on the combustion chamber to wash off, worse than say just running straight gasoline....that isn't actually what you were trying to say, right?

M104-AMG

iTrader: (8)

Correct.
