any solid proof mmo works in motors?

Hiltzy,

You make a good pt. Can't find any fault in it. But -

First, I primarily use these brews in my gas. Fuel pump lube, upper cylinder lube, carbon deposit control/clean and in the case of Neutra - atomizing the gas spray for better injection distribution. MMO may be Mystery, but I think it's similar to Neutra - and Schaeffers markets to the industrial world - not to Billy at Wallies (you can pass stuff off on Billy, but not so much on fleet & heavy equip. mgrs). And Schaeffers has a great reputation on BITOG for marketing things straight up w/ full discosure etc.

Second - there are various and asundry reasons to have it in the crankcase (for some of us) - here's how I've historically used it -

If I'm running a 5w30 in my Sienna coming into the winters months (and it does have some consumption) - then around December I'll top it off (up to a qt) w/ MMO. It may all be in my head, but that puppy starts running smoother and has nicer start-ups on cold mornings. I dump the whole fill first sign of Spring. And it may/may not be doing some extra cleaning during the run.

Here's a link to Neutra 131 - from a company that doesn't go the hyperbole route -

BTW - Schaeffers also has a page stating the use of Neutra for the crankcase (last 500 miles of an OCI). Works has a slow cleaner on varnish/sludge. Though I've never found anything that worked on OLD varnish in the valve area of my previous 88 323 - and I tried most of what's on the market.

MMO Works
SeaFoam Works
B-12 ChemTool Works
They say Techron works.. but i believe the Previous 3 Work, Period.. FOR GAS

For OIL: Seems MMO Works...
SeaFoam Works as well, but it must not be as "Safe" as MMO (However, ericthepig's Statement is Equally as true for SeaFoam, It seems it is Harmless at worst, and does what they say at best.)


I always understood black oil didn't necesarily mean anything either. Oil color does not really indicate whether the oil is still in good shape, or what may or may not be suspended in it. I am sure different oil brands and viscosities, synthetic, blend or conventional oils will all wear differently and be different colors at different stages over the length of an OCI. But I use Napa or Carquest brand 10W30 exclusively. Napa and CQ oil is made by Ashland and is the same as Valvoline brand, except for a few very minor differences in the additives. Whatever differences exist are very inconsequential. It's a great oil. Before using MMO when I would change my oil, it was always a nice dark brown color. I could probably go longer but I always change my oil at 3000 miles. On the OCI that I ran the MMO, that oil came out a really dark black color. So I know the MMO had to have done some degree of good cleaning. That's why I think the color of my oil with MMO indicates it is a good internal engine cleaner.

Worked for me in gas and oil. Cleaned out a varnished up carb on a 440 MOPAR and a Kawasaki 750. Unstuck a lifter that was chattering on our 95 Grand Prix with a 3100 motor.

I do not have to convince anyone it will work for them, because it might not thanks to unknown variables. But it has applications where it works for me and I will keep on buying it and using it.

I only use it as a short term flush though.
 
I have used MMO for many many years ans it works just as advertised. I spray it on blocks and cranks in the shop for rust protection and add it to the engine oil of cars that are having build up problems. Works every time!

I guess the real question is: Any solid proof that MMO does not work?
 
I filled up on the way home tonight, 14.7 gallons of Texaco 87 octane at $2.87 per gallon. I just now calculated my MPG based on the difference in miles from my last fillup divided by 14.7 and I got the best MPG I have had in over a year, 19.23. I have gotten between 20 and 21 MPG before, but that was when I had Michelin LTX tires. I have Firestone Destination LE's now and they have a more agressive tread pattern which caused a bit of an MPG loss. But they are still a great tire for the price I paid. I run 40 psi to help increase MPG too.

I am very happy with 19.23 MPG. I hope it continues. I added about 5 ounces MMO to this new tank of fuel, same as I always do. I am about 1200 miles from my next oil change so I went ahead and added half a quart of MMO to my oil tonight too. I started my truck in my driveway to circulate it and in just a few seconds I could tell the idle was a lot quieter and smoother. The MMO should give an increase in power too, the last time I ran it in the oil it gave a very noticeable power gain. My engine has a problem with a slight RPM stumble right after a cold start in the morning, it goes away after I drive about half a mile. When I ran MMO in the oil last time, that stumble was completely gone.

I really like the improvements I get with MMO. It helps my old truck run better and have more power, and I get better gas mileage with it. I hope everyone who has questions about MMO reads these posts and the countless others and MMO works as well or better for them too.

Sorry it didn't work for you. Did you try it?
 
Next you will try to tell me that chicken soup doesn't help the common cold...

My truck ran very smoothly this morning coming to work, nice even acceleration and less noise from the engine. My Dakota has always had a slight vibration at idle and Dodge has always said it's a common characteristic with the 3.9 V6. Dodge's cure for the vibration was to flash the PCM to retard the timing about 4 degrees, but the vibration is still there, just not as bad. MMO in the oil smooths that vibration out, just about eliminates it.

I found out when I started using MMO that the people who post negative comments about it, most of them have never tried it. It took me a lot of research and time before I tried it in my oil. But it works very well and of all the posts I read about it, I have yet to find one single post or online article about MMO causing any damage to any engine.

My truck runs a lot better with MMO than it ever did without it.
 
MMO works great cleaning up any fuel related issues. Helps clean up dirty and neglected engine issues caused by infrequent oil changes.

I use MMO in older vehicles every other oil change the last 1K miles of a OCI. I also use it in the fuel tank every 4th or 5th tank of gas. Using it in new vehicles really does not do anything and if you ran a good SM oil every 3-5K miles your engine would stay clean. I do think using it in the fuel tank does help keep your fuel injectors, etc clean...
 
One thing that is eliminated in gasoline is lead.
The deposits left in the engine were cleaned especially well with MMO.
Aircraft fuel can still have some lead, and many use it in the fuel for cleaning and reduced valve sticking from melted lead deposits at their almost full throttle applications.

But MMO is not without use anymore in cars, by a long shot.
 
MMO is great. But what i dont like about it is that what every the amount you add it burns off over time....at least for me it did.
 
Using it since the early 70's it has proven itself to me and friends that it works, time and time again. New products come and go, small companies frantic to push their products, sometimes knock MMO making baseless claims, this speaks volumes. After all you always go after the #1 threat. When you're on top you have to watch yourself. Funny thing is the MMO people will never say bad things about another company, I like that.

The greatest part of all is at less than $5/qt it's cheap. I tell my friends in doubt to try it and see for themselves if they have a problem, they always come back and thank me. As the saying goes, you can lead a horse to water. LOL
 
It might serve to verify the tenacity of modern engine oils. You can dilute well-formulated lubricants with 25 percent of "other" without causing sudden failure.

I'll stick with lubricant. I have never needed anything else.

You're right it could be gunk engine flush, my bad.

If not what is #1? The point is the same people (you, and a few others) that attack MMO will attack Gunk. The company that does the attacking is most likely selling the least product too. Strange isn't it?

I'd rather not get into it with you, you have your beliefs, I have mine. I've tried a lot of cleaners including some pricey stuff too, I know what works best with any oil I care to add it to. I don't have to drive like I stole it for 20,000 miles either.
