MMO in ford explorer 4.0 sohc engine

[demarpaint]

Sounds like you have your work cut out for you, lots of variables as you already mentioned. I've done piston soaks with it and had positive results, on small engines, and have one example of it freeing up rings and improving compression in a boat engine. My brother and I were talking boats, and he is at the crossroads of buying another engine. He brought up the story of an old Chevy engine and reminded me of this.

Years ago one cylinder in a Chevy 250 I6 we thought was out to lunch in my brothers boat. We ran a Compression test and in cylinder #3 and #4 it was about 20%+ lower than the others, and you could feel it in the engine, we could never get this thing to idle right. Anyway my brother was in the process of ordering a remanufactured engine for this boat. He had just bought it used to set up for offshore fishing, it was mid season and the engine swap was planned for the winter.

The Biggest problem was with salt water cooled engines you never know when the water jacket is going to rot through, so rebuilding this engine with an unknown history and over 15 years old was not an option for us. We also had some lifter noise. My brother said [censored] lets toss some MMO in the oil and run it till the end of the season, we'd stay in the bay so if it broke down getting a tow wasn't going to cost us the farm.

We used this boat for about 3 months and logged about 50 or 60 hours. The engine actually ran quite well, when we took the boat out. The lifter noise gone, and the compression in the weak cylinders came up to within 5% of the other cylinders. We swapped the engine, and now my brother is talking about doing a swap again, some 15 years later. This engine runs like a top, but the water jacket is questionable.

My brother claims he had similar success with an old Caddy Seville and MMO boosting compression, but I didn't help him with that car.

I use it MMo whereever I feel neccesary. Initially got it for my Jaguar XJ w/ 4.2 v8. Added it within the last 500 miles of 3k OCI's, about half a quart. Really darkened the oil which make me think it cleaned up some areas of the motor.

I also had an idle fluctuation of about 100 rpm at idle, thats gotten better and is down to probably a few rpm.

I also added 5 oz to the gas tank.

I changed the oil on my 5hp snow blower (4stroke), and added about 1/4 qt of MMO to the 1 quart resovoir. It turned that new oil black within 15minutes of use. Then I flushed and refilled with oil and added a much lower ratio of MMO. Runs awesome now, where as it ran pretty awefull before, even after I changed the sparkplug.


Then I used it on my 03 honda xr80r 4stroke dirtbike. Ive had this bike since 04 and have stopped riding it daily in 04, but I would occasionally start it every few months. As time went by it was getting harder and harder to start, and running rougher and rougher. All with fresh gas too.

So then it wouldnt start for [censored], my father looked at it and said it was the spark plug and the motor lost compression. so the next day I removed the sparkplug and it was fouled badly. I sanded it down, poured about 2oz of MMO into thecylinder and let it soak for 10-15minutes.
Then with the sparkplug out I gave it a few kicks to cycled the cylinder a few times to remove the excess MMO and have it lube the whole motor.

Then I installed the sparkplug, and I could NOT beleive what happened....The bike started on a half a kick. This after both me and my buddy were kicking and kicking for about an hour trying to start it a few nights ago.


All in all, I just did a PS fluid change on the Jaguar and will also add a few pints to the PS resovoir to lube things up.

I added a 1/2 qt to my buddies 06 civic ex with 44k miles on the motor for the last 500miles of his 4k OCI's and he loved the way his car was riding. after he changed his oil he said it drove better with the old batch because of the MMO.

I recommend this to everyone with older, higher mileage cars as I described here. or lower dosages on newer cars for good maintenance. I plan on never buying injector cleaner or fuel system cleaner again, this does it all IMO. Plus its sooooo cheap.

you can see photos of the Jaguar filters and what I did here

I like that method you use in the snow blower!

Nice write up, seems like it cleaned up the rings in a few of your applications!

Thanks, it used to give me such problems at higher drivewheel speeds (more snow per rev) and once done with this it practicly never bogs. Really its SO cheap and walmart and last for so long, works great I dont understand why there are dedicated naysayers.

I also read alot that is does nothing on certain cars. I can udnerstand that too, its why I dont add any or use it at all on my 2010 civic lx. And wouldnt use it on my old e-350 that needed 1qt of topoff oil everymonth, reason being is that top off oil dilutes the MMO that remains in the crankcase , and whereever your original oil is going the added MMO is going too. Thereby making it seem as it doesnt work.


To each their own, I pitty the folks who dont use it and I see now they pitty the folks who do. Your loss

(its just $3 at walmart !)

Seems we think a lot alike, and have lots of success stories! It must be a NY thing, I was born in Brooklyn.

 

[StrateLOSS]

Yeah, seems like we are alot more level minded here then in other areas of the US. My logic was (and you can see by my posts of the link I provided) that its just $3 to try it, thats the difference between making a cup of coffee at home or driving to dunkindonuts and getting a medium coffee with cream just 1 time in my life. If it worked, then it worked. If not, oh well I just wont go to dunkin donuts tomorrow and drink coffee from home

 

[demarpaint]

Many frown upon that mindset (only $3 or $4, so no great loss). I think if MMO sold for $20/bottle it would be respected more by some people.

 

[StrateLOSS]

oh well, more MMO for us.

I like the smell. Since I started using it in my mowers and blowers, they seem to start easier. I havent had the carb troubles as much either.

OK

if all you New England guys are done patting yourself on the back..... Some of us Midwest guys are practical as well! LOL...I am using a 20 oz in a 4.2 litre engine I just put in a truck. The LKQ engine was a crash part that had sat for 2 months when I boutght it. After installation I have some valve train noise on start up and accelration.

It has been greatly reduced by the addition of the MMO. I will swap filters to get the mix up to 1 quart. I will run this to the end of the 3K OCI and replace with PP or Ultra.
