The search function can be a PIA at times, so here is a condensed version of my experiences with MMO. Real life, and no I'm not getting anything for free, and I don't work for them in case anyone is wondering.
Here is what it has done for me, family and friends.
Stopped lifter noises in many different engines over the years, sometimes it can take more than 1 OCI.
Reduced oil use if it is caused by sticking rings!
Freed up a bad float in my gas tank. The gas guage would not read properly after about 2-3 tanks of MMO it worked and stayed that way for many years until I sold the car.
A buddy had a really dirty engine visable via the oil fill hole. About 3 oil changes later using 1 qt MMO per oil change the engine was extremely clean and running better. I've seen this many times over the years and it cleans them up nicely.
It has cleaned piston tops in small 1 cyl engines and kept then clean.
I've used it as a fogging oil with great results.
Made engines idle better.
Aids in cold winter starts, in a very big way.
I have been using it since day 1 in an 88 Ford Van which I still own. Original cat converter.
We treated my son's BWM prior to his 3 deployments to Afghanistan with MMO, and the car bounced back to life without any issues. Adding a heavy dose to the gas keeps the combustion chamber from flash rusting.
I use it in everything I own that burns gas: mowers, snow blower, power washer, line trimmer, 2 cycle outboard engine, and the chain saw. I ran a chain saw without it and had some carb issues. The saws I used the MMO in are less prone to carb problems, IMO.
