any solid proof mmo works in motors?

[mechtech2]

People have fallen out of airplanes and lived.
This does not prove that people can safely fall out of airplanes.

So prove that MMO works? Works for what? There are too many situations to consider.

I would go to their website and peruse the links - that is a good start.

I use it in gas at every fill up as UCL and to lubricate the fuel pump. Incidentally, it helped my gas mileage, especially in a 3.5 L V6 Isuzu.

I used MMO twice in oil for the last 500 miles in a new-to-me Kia Spectra. It started its life as a rental car, so I decided to be proactive and do some cleaning. I currently have PP 5-20 in it w/o any MMO. I might add a pint before the next oil change this September, and then I'll stick with synthetic oil only.

I also used MMO in oil in my 10-year old Isuzu (as well as gas). Isuzu has been maintained very well (5-30 GTX changes at the dealer every 4 months or 2000 miles--lifetime oil change contract), but it is used only for city driving with extended idling, i.e severe service conditions. I ran one "last 500 miles" cycle in it with MMO. Some of the Isuzus had problems with stuck oil rings and burning oil (mine does not), so I am hoping to prevent it by keeping pistons spotless.

Sounds like a good plan. You might want to stretch that last 500 miles to 1000 miles in an engine that has problems with stuck oil rings. That would give the MMO a little more time to work. You could even try a full qt for a full OCI during the Alaska winter.

I believe there are benefits to using MMO on a regular basis, and I do use it with my favorite synthetic oil.

1) It will keep the engine clean, even if you do short trips.
2) Easier starts and faster oil flow, especially during winter.

The one big reason I use MMO in my oil is becuase one of my car's has an ALUMINUM ENGINE, and I have found that aluminum is porous, which means that any contaniments that may form will really stick to the aluminum and those contaniments can be hard to remove.

A member here had his cylinder heads cleaned, and he continued to use MMO in his oil, he posted some pics about 15,000 miles later and the aluminum cylinder head surface was still clean, if the surface of the aluminum cylinder head is clean then that means oil can flow easily without being blocked by contaniments.

I just feel it is easier to keep an engine clean as opposed to trying to clean it up, so if you clean up your engine, then why not keep it clean.

I just might. The problem is, normally I have dealer change oil in Isuzu. Depending when the fall change date is, I might do it myself. I hate changing oil in 20 below temperatures and snow drifts (do not have a garage). Been there, done it, had a bad cold to prove it.

That's why I went with synthetic oil in Kia. Change it twice a year in the spring and fall.

i can't comment on mmo in the crankcase, i tried it once for a few hours in a used engine, then dumped it.

but mmo in the gas i have seen unbelievable positive results
i have 2 mid-60's 292 I-6 chevrolet engines along with a '48 ford flathead v-8 in trucks that are used maybe 20 hours a year, idleing 95% of the time to run pto and have always had rough running issues due to the nature of what they are being used for.

well over the past 10 years or so i have been using several different lead substitute additives with very little sucsess, so this spring when i getting all of the equipment ready for use instead of using the lead substitute i instead mmo'ed all of the gas.

after about 20 minutes of ideling the first chevy smoothed out and ideled probably better than it has in over 30 years, my dad wanted to know how much money i wasted on this old truck to make it run so smooth, when i snickered and said less than a buck he didn't believe me and we have been fun with this ever since.

the same happened with the other two trucks, the mmo is doing what the lead substitute was supposed to be doing for years and it only took approx. 20 min.

needless to say the bulk gas tank (275 gal)has been "mmo'ed".
i don't know if the results of a modern engine would would be as pronounced, but it sure can't hurt anything.
i'm sure its a combination of cleaning the entire fuel delivery system, along with valves,pistons, and compression rings
