[@janmessek1826]

If you remove carbon buildup from the combustion chamber that will lower the compression ratio and lower the compression reading that you get. The idea is to remove the carbon that could potentially cause pre ignition and that's what marvel did.

[@a.c.r.smallenginerepair3158]

Pretty much exactly what I posted just now before reading your comment. Glad to see there's somebody here that knows what they're talking about.

[@DirkWrightxyz]

However, if the rings are stuck, then if MMO makes them start working again, then the compression would go up. So, unless this engine had stuck rings, I don't think MMO will increase compression.

[@here_for_the]

Flat head engine designs are a bit more about Combustion chamber shapes ( which includes both the piston & the cylinder head. Vs just a bit higher or lower compression ratio. A leak down test would have been much more accurate to define ring seal, than a cranking compression test that might be effected by carbon buildup or removing of said build up. Best way to measure the engines sealing efficiency is always a Leak Down test. Professional racers leak engs much more often than doing a cranking compression test. Good video. Ive only used Marvel on older engines & flat heads. & used Seafood on later model stuff & overhead valve designs. Thats what works for us.

[@kickblake]

Compression ratio doesn't change with carbon deposits because it is a measure of MAX volume to MIN volume. As the max volume is reduced exactly as much as the min volume by carbon deposits, the ratio doesn't change. Compression testing is really measuring ring and valve seal more than it is compression ratio.

[@shawnlibby675]

But he used two different lawn mowers...one motor had more compression than the other.....now if u find a small engine with a stuck ring..and see which one will remove more of the carbon

[@johnbradford2852]

I learned from my father to use marvel to free up rings before putting fire (ignition) to an engine that has been sitting for a while. Used it to free up a seized ford 302 that had been sitting for over 13 years by putting in every spark plug hole and allowing to sit a few days. Next turn by hand to free up and spin with starter once it spins freely. Finally put plugs back in and smoke out the mosquitoes in the neighborhood. Compression was nice and even 150 psi.

[@JQ_Unity]

im about to do this with a 302 volvo penta. I put engine restore and lub in the oil and it SIGNIFICANTLY changed compression. Now I will soak everything in MMO. This thing was running when I bought it

ATF works pretty good too. I prefer wiping engines down with ATF if they are going to be on the engine stand for awhile. No rust or scale.

[@lenBrill1971]

Diesel fuel through sparkplug holes is another great way of freeing up a frozen engine. Fill and walk away for a few days. It works every time. Turn it over with a socket and long bleaker bar on the front crank bolt at the harmonic ballancer. Leave the sparkplugs out and work the bleaker bar back and forth.

I have used Marvel Mystery Oil and Sea Foam for many years (20+). My opinion is that I use both at the same time mainly in my gasoline. I take care of my equipment and it does the job for me.

[@eriwilnel]

yes its common with cleaning additives. Word of caution --use only enough to get the piston covered and tilt the mower upwards (only on push mower) make sure to make a few pulls on the engine with the spark plug removed before putting the plug back in. This will prevent hydrashocking the engine.

True story: I used to put MM Oil in a 1995 Toyota Camry that I had years ago. I would pour about 3/4 of it into the engine and the remaining 1/4 into the fuel tank. At one point in my life I was driving cross state lines about once every other month on weekends and during the Christmas holidays to visit my daughter back when she still a little girl in the early 2000s after I got divorced. At some point, I developed a crack in one the piston heads and the mechanic told me that even though he was amazed that I managed to break a Toyota engine, he was more surprised by how clean it was on the inside of the motor as he tore it down. He said usually he sees a lot of carbon build up but on the inside of my motor it was fairly clean with very little build up. So I give MM Oil a thumbs up!

I have spent my life in aviation too, Bradford. Many years as a flight instructor them a career as an airline pilot. In the 1970s I gave a Biennial Flight Review to a man in his personal Cessna 175 Skylark. I'm sure you know what a poor maintenance reputation the Continental GO-300 in the 175 had. The owner told me that he did frequent oil analysis tests because of the poor reputation of the engine. At first the analysis tests reported concerning metal content, but an "old" A&P recommended 10% MMO in the engine oil. He claimed that all oil tests after beginning to use MMO reported no concerning levels of metal. I have been using 10% MMO in my car engines since. My 1999 Jeep Cherokee, with the 4.0L 6cyl (a bulletproof engine anyway), last September (2018) pulled a 3600 lb trailer 2000 miles at highway speeds from MN to into mountainous AZ with no issue, and averaging 15.1 mpg. The odometer turned over 252,000 miles as I backed the trailer into my garage.

You used a different type of spark plug with the Seafoam than you did with the Marvel Mystery Oil but I believe from what I can see that the Marvel mystery oil did a better job decarbonizing the top of the piston and the valves than the Seafoam did. Probably 16 years or more ago this girlfriend that I had she drove a Honda Prelude and it had a cracked cylinder head when I met her and I opened it up slightly with a cut off wheel on a Dremel and then I pushed JB Weld in with a syringe and then I smoothed it all out after it hardened and reinstalled the cylinder head she drove it for another 5 1/2 years after that and she did not retire the car because of any problems with the cylinder head or engine but just wanted to get another car and sold that car that did not smoke!

I think that MMO is made for repeated use in order to get the best results. I use it in all my power equipment fuel (mixed as directed for auto fuel, and mostly a bit heavy for lawnmower, trimmer, chainsaw, blower and generators) and I have had ZERO issues for almost 20 years. When my trimmer quit working (magneto issue) after 9 years, I took it apart and it was as clean as a new one inside. I have used MMO to clean up neighbor's lawnmower carburetors from a year of gumming up from them using 10% ethanol gasoline (which I would recommend to anyone never to use in power equipment) by mixing MMO heavy with fresh non-ethanol fuel and running it through the carbs for an hour. Both lawnmowers have been fine after cleanup process was done. I have used seafoam, as directed, on one truck engine (ford 5.4L) after buying it used, and it "seemed" to run better after using it. Although I have nothing against seafoam, it tends to be more of an expensive additive. Not that I am against Seafoam, I use MMO because I can get it for $3.88 at Walmart and because I have 19 years of consistent performance from using MMO. Marvel claims that MMO stabilizes gasoline, and I have gone two years with MMO in gasoline, in my chainsaw without starting it, and when I did finally get around to using it, it started on the second pull. Just my 2 cents opinion folks.

What a fantastic company just for keeping the cost down.

[@sweetwilliam49]

TreesOnTheBeach I agree mmo did better! Can’t understand the compression test. How does an engine get less compression after treatment? That implies mmo is hurting the engine. The pictures don’t confirm that

[@ians2777]

@@sweetwilliam49 I think it would depend on what the goal is and what "normal" for the engine is. Uneducated/semi-educated opinion: Assuming both products improved the performance of the engine, raising compression would seem to be from freeing up something like a ring or lifter that has trouble moving, or getting deposits off exhaust ports to complete a lifter seal. Lowering compression would seem to be from cleaning off deposits from the faces of surfaces and leaving more room in the combustion chamber. Since there is now more room the fuel mix is not compressed as much meaning of course less compression.

[@sweetwilliam49]

Ian S I can agree with that assumption, that would imply that the engine was working with no loss of compression before the treatment. I guess it could also be assumed the cylinder would have more space to draw in air to increase volume and therefore more compression

According to your numbers MMO is 4 times cheaper. 1/2 the price for 2x the product, Furthermore, according to MMO's website, you use 4 oz of MMO in 10 gallons of gasoline. They don't recommend adding more than that. On the other hand, Seafoam suggests 1 oz per gallon, or 10 oz per 10 gallon. It also says you can use up to 2 oz per gallon. Sounds like they basically want you to just dump the whole bottle in effectively. That means you need to put in 2.5x as much seafoam. Which means MMO is 10 times cheaper!

[@ProjectFarm]

MMO is a great product!

[@RockandrollNegro]

john handcock, as far back as the 80s, Marvel used to have directions on the can (back when you could still get it in a can) for long-term fuel storage, and it was recommended to mix one ounce per gallon if your vehicle or tank was going to be sitting for a while. Kind of like Sta-Bil, but much cheaper. I've mixed as much as 2 ounces per gallon and have not had any issues doing so. But yeah, the recommended dose is 4 oz per 10 gallon tank.

[@PayNoTax-GetNoVote]

Good catch!

[@anonymike8280]

The base of all of these products is some form of naptha and sometimes turpentine or its petroleoum equivalent. In general you cannot hurt the engine or the sensors by using more than the recommended amount. The point however is that there is nothing that makes one of the products better than the other. Walmart has Seafoam, Gumout and its own product right next to each other arranged by price. There is no difference between the three in terms of what they will do. The same for gas additives intended to clean fuel systems. Probably, two or three bottles of some dollar store additive with do the same thing as a much more expensive product though you may have to go off label. Mystery Oil will work as well as a gasoline additive in a stored avehicle as the much more expensive Stabil. If you have to store a vehicle the best thing to do is have the tank low when you park it, throw in a couple of gallons of fresh gas when you start it, and go fill up at a nearby gas station. You can put in a storage additive if you wish but it probably will make little difference. I once helped a friend start up an vehicle that has been stored for years and it ran. It was never driven again but it would have made it to the gas station across the street if that had been the intention.

It's so hard to say, is X better than Y or Z. Each have their own characteristics. It did seem that the MMM resulted with a "dryer" surface, but it didn't remove the flaky scale left behind- whereas Seafoam seemed to "wash" the surfaces, but left them wet looking. Both products are better when used in oil AND fuel together, and given time to work. One test with any product isn't really going to do much, or give drastic results to show. I still stand by my original method of a 1-1.5 quart replacement of 50-50 ATF/Acetone in fuel and oil, run about an hour at high idle- for a real "engine wash" (for cars/trucks).

I’ve been in the automotive industry all my life and retired a year and half ago. Some products I have used have proven time and again to just plainly work. Like MMO, Rislone is one of them I have seen proven results. Rislone, MMO of ATF have all been used time and again successfully from the old timers. 1st time I was exposed to Rislone by my mentor at a Ferrari dealership in Hollywood, Ca., a Ferrari Daytona 365 V12 was towed in with a bad hard starting complaint and lack of power. After numerous test for ignition and fuel we found a lot of blow by from the crankcase breather. We also verified a low compression across all cylinders with a follow up leak down loss from piston rings 20/30 %. My mentor Mr. Samps requested to contact the customer for an authorization to decarbonize the engine using Rislone. The process was relatively simple considering a very expensive alternative of an engine tear down and re-ringing job. We added a quart of Rislone to the crankcase, finally got the engine started after numerous attempts using a battery booster, then up to normal operating temperature. The next step was removing all the spark plugs while the engine was hot. Samps got a squirt can and 5 to 6 pumps on each cylinder later while tapping the starter motor. We let the engine sat over the weekend. The following week we placed rags on top of the spark plug holes and crank the engine over to bow as much of the excess Rislone out of the cylinders. Next we installed the plugs and fired the engine off. Yeah, it did smoke for a while obviously. A few wraps from the throttle later the smoke finally cleared and we checked the crankcase fumes to verify results. Indeed it was reduced to almost non existent. We verified success a few consecutive days later that it was a solid and successful repair. Leakdown afterwards was a marginal 6/8%. Wow...Now I swear by Rislone and it has never let me down. I use it often, a 1/2 quart at oil change intervals have kept my engines running in tip top shape. Something to keep in mind: 1 . Engines will always accumulate a certain amount of carbon from both fuel and oil. 2. Carbon will always find itself into the ring lands causing rings to stick, reducing their primary function and efficiency. 3. That will bring in burnt gasses from the crankcase reducing the incoming air/fuel charge. 4. Hard starting, lack of power and high oil consumption will be the result of sticky rings.

Had an '82 VW air cooled van that from time to time had sticky valves. All I had to do was add some Rislone and that was it no sticky valves and quiet as can be.

[@saltydog3714]

I have been using both product for years. I believe that MMO gives more bang for the buck! Sea foam works great in the oil for freeing up a sticky lifter on my twin cylinder Koehler engine . I actually mix both products together in my gas can. Great video, thank you!

[@Ethan-jh4gj]

Im currently trying to find the best stuff to help a ticking lifter ... Was gonna run MMO in the next oil change . You like seafoam better ?

[@robertyoung9467]

So do i.

[@genefoster8601]

How did you get a sticky lifter on an engine that doesn't have hydraulic lifters? Better go back to school before entering bogus opinions.

[@duo315]

You could use (sorry this is kind of a weird suggestion) an enema bag with a stopcock to very accurately control the rate that fluid is added. I work in healthcare and we have more tools at our disposal, like IV tubing with roller clamps, dial-a-flows, and of course, IV pumps, but the closest thing I could think of that's available over the counter is an enema bag

[@ProjectFarm]

Thanks for the feedback.

i have at least half dozen enema bags at home. they also work great for enemas!

Still drive my 99' F350 7.3 4x4 dually w/over 400k miles & have consistently been using MMO in every 3rd-4th refueling. Enjoyed the video comparison, have seen Seafoam just never cared to change old habit.

[@0HARE]

I have that same truck. Been using Lucas fuel treatment in it for about seven years. Engine runs great. I’m open to using MMO or SeaFoam, but, it seems that this test was inconclusive.

[@elektriceye]

I like that seafoam increased compression, that's pretty impressive. Great videos man! The amount of work and detail you put in is astounding!

[@ProjectFarm]

Thank you!

[@bobthrasher8226]

SF started with a worse compression though... So in a way that was expected.

[@fixitallpaul4847]

If you remove carbon you decrease compression.

[@elektriceye]

​@@fixitallpaul4847 not if the rings were stuck and causing lower compression or if the valves had carbon build up where it seats.

[@fixitallpaul4847]

[@hitchman0011]

I love your shows. It super cool that you pay for your own stuff to post for others. The fact that you do this alone is reason to watch them. I watch the series on Amsoil car oil vs other synthetics. I was so impressed that I shared the link with an Amsoil rep out of Caldwell ID. Thanks and keep up the great work. Please.

[@ProjectFarm]

Thanks and you are welcome!

[@onlawn]

These tests are great. I'm not sure where you have such a large supply of engines to test, but I'm glad you do. Bob the Oil Guy is an old forum that used to debate this kind of thing all the time. I think the greatest and longest lasting oil / gas additive, valve train and upper combustion chamber cleaner battle they had was Neutra vs Auto-RX. For the kind of stuff you spray into the intake, the Amsoil foaming cleaner was pitted against Seafoam, and generally considered the favorite.

[@ProjectFarm]

I'll see if I can find each of these products! Thanks for watching the video and commenting!

[@buzzsah]

I have been MMO in all my fuels for years, all my yard tools, tractors both gas/diesel, our vehicles, All fuels. I find everything runs smoother, cooler over time, and better mileage.

MMO is a terrific product!

[@jackdaniels7913]

I've used marvel in the gas tank on ever fill up for a year now on my 09 6.2L V8 and my fuel economy is better then wen I bought the truck so I stand behind marvel mystery oil I've also used it in the gas and oil of my atv for years with nothing but good results... thank you for every video you've done and everything to come I got one really appreciate your time and effort! 🥃cheers🍻

Thank you

[@MsKewi-NYC]

So is MMO just like Seafoam you can pour it in the fuel tank and in the motor oil as well??🤔 I gotta go look at this then for my 94 4runner.🤔👍🏾

[@jackdaniels7913]

Yes it is I use it in my 09 Sierra Denali on every fill up and with every oil change ! It works wonders and has never done me wrong hope this helps and good luck. 🥃Cheers🍻

[@ProjectFarm]

Thanks! Thanks for sharing.

[@deanherrington]

MMO was used extensively in WWII inside aircraft engines, and as a fuel additive. Those engines ran under the most severe conditions possible, often at War Emergency power settings, and ran until a .50 cal, 22mm canon shell, or flak took them out. That's good enough for me.

[@rodneyharouff5739]

i love the videos you do. simple,no garbage included. & very common-sense tests. very informative.

[@ProjectFarm]

Glad to hear!

[@ecrusch]

Man, this is one hell of a channel! Thank you, brother...honest.

[@WagsAutomotive]

I'm impressed with the results of the Marvel Mystery oil. I wonder if the compression went down because it did such a good job of removing the carbon? Carbon buildup increases compression, so maybe compression went down because it cleaned it off so well? I think so. I've been using MMM for over 40 years. It's great stuff. For my money, it's MMM! 😁

[@davidjameson1898]

Same thought process I used as well after seeing how much cleaner MMO in the after photos.

[@coldlogiccrusader365]

Yes, I thought the same thing also. Removing the carbon, increased the cylinder's volume a tiny bit, hence slightly less compression.

[@letsrock8899]

Same thought when I saw the slight decrease. It seems to have done a bit better cleaning, especially on the cylinder head.

[@mdfield1]

That’s must likely what happened. A more accurate measurement would have been to know the actual compression when the motor was new.

[@djfunkycraig]

Good point!!

[@2_be_determined]

not sure what video everybody else just watched but in my opinion mmo won that great job with the videos ill keep watching for sure. also thanks.

[@richardross7219]

I've used Marvel Mystery Oil(MMO) since 1967 when my grandfather introduced me to it. I have had much better results than you showed by giving it more time. I used to do the dump it down the carb but over the past 20 years I went to just putting it in the gas. I picked up a minivan 20 years ago that smoked a little and had low compression in a cylinder, it was a 4 cylinder engine. I put MMO in the gas at every fill up and used the van for going to work. That was about 50 mile round trip 5 or 6 days per week. After several months, it didn't smoke anymore and ran smoother. At about 6 months I did a big service on it the compression on all cylinders was good now. I did a 283 in 1970 where I did the MMO down the carb until the engine stalled. I let it sit for several days and then started it. It smoked like a Uniroyal stack for a while. I pulled and disassembled the engine. Most carbon was gone but the rings were stuck in the pistons. After running another engine with MMO for several months, the rings were free when I disassembled it. I put MMO in the gas of all my machines and believe that it really hepls. It also seems to prevent corrosion in the fuel systems. Very good video. I hope that you are picking up those mowers for free. Good Luck, Rick

[@ProjectFarm]

Thank you. Thanks for sharing!

[@colt45peacemaker]

Mmo probably cleaned the sludge off the oil and compression rings

[@k5ren]

"Smoked like a Uniroyal stack" Very descriptive Richard! I get a perfect picture of it, and i can even smell it!

@@k5ren There was a Uniroyal factory in our county. When I was a kid in the 50s and 60s, "smokes like a Uniroyal stack" was a catch phrase and an insult to other guys cars.
