When I was approximately 12 yrs old, My Dad was given a 1946 Hudson Pickup Truck which has a small 6 cyl. engine in it that was seized up from not being used for so long. So we towed it home and My Dad took out the spark plugs and poured MMO into each cylinder and let it set for 2 weeks. After two weeks we tried to turn it and sure enough...... it did. Amazing stuff.
+Art Prescott nice, thanks for sharing.
I've used Marvel Mystery Oil for 50 years, in both my oil and gasoline. Over the course of all these years, I have never had a major engine repair. I believe in MMO! Thanks for posting the video!
Thanks for sharing!
Can you put it into the carb
@@henryewald9327 Hi Henry, I'm 67 so I have been a Marvel Mystery Oil user for many years. Back in the day, yes I used MMO on my cars with Holley, Carter and Rochester Carbs. Adding it to gas kept the jets clean. I also put a little in a small oil can, to put on the throttle flap hinges and linkages. My Dad was using it before me. It has always been a very good product.
I would not use MMO in gas tank not good for catalac converter and oxygen sensors
Out of all the videos like this, this one gets my only thumbs up because you actually know what you are talking about.
Sir I Drive a semi Truck that hauls Liquid Asphalt. I noticed my Truck Sluggish on Hills that it normally takes with no problem. So I put in the MMO in my fuel. Almost immediately I noticed my Truck come back to life the same day (540 miles). Then I thought of putting a piece of hardened asphalt in 1 once of MMO. Since Asphalt is Oil. Immediately it started to melt the Asphalt back to liquid form. I the test bottle in the side box and moved on. The next day I checked it. The MMO had dissolved the piece of Asphalt back to liquid. I am sold on this product! Gonna put it in my engine oil next on all my vehicles! Keep up the good work. I’ll keep on Trucking with this Product.
Wow! Thanks for sharing.
Listen to this guy because he really knows what hes talking about. There are very few people like him on the internet left these days. Not too many people have the experience this guy has trust me he really knows what hes talking about. Its all about the personal experience and whos been around the longest and who really knows and this guy does know and his advice is perfect.

Awesome, thanks for sharing.
So you mean that even "modern" cars that use "modern" motor oils and "modern" detergent gasoline still experience issues of carbon build up, sludge, varnish build up, clogged fuel injectors, failed fuel pumps due to insufficient lubricity of even top tier fuels, seized piston rings (regardless of the fact that top tier fuel was used and quality "modern" motor oil), clogged/destroy cats due to prolonged exposure to dirty exhaust fumes brought on by the previous mentioned issues......... yeah, l just gotta laugh when people who should definitely know better than to say that today there is less of a need for a proven product that is safe and beyond any shadow of a doubt provides much better cleaning abilities that ANY top tier fuel or modern motor oil alone and yes, even in today's "modern" cars! The vast majority of issues that l deal with when servicing cars with running/performance issues l can trace back to carbon build up, sludge build up, (regardless of the fact that regular service was done using top tier fuel and quality motor oil on schedule) which then lead to other issues, and yes, that is in modern cars! Some of these issues that l've had to repair, once the repair was completed, l suggested to the owner a regular routine using MMO in the fuel a few times per year and in the crankcase 300 miles before oil changes and voila! Even 10 years later, they have not experienced those carbon/sludge/oil flow issues again! "Modern" motor oil/"Modern" gasoline my ass LOL!
Its great stuff. Ive been using it for a long time in my 94 silverado. I quart of MMO every oil change. And ive got 330,000 miles on the 350 engine and it still runs great. Good job sir.
Awesome! Thanks for watching.
Thank you sir. Also, great point about proper maintenance. I recently junked a 1992 Taurs. She had 380,000!! I was trying for 400k. Head gasket blew, didn't have money for repair, or any place here in NYC to DIY repair. Car was given to me as gift with only 74,000 miles. We had a long run together.
+Christopher Schemer Very nice. Great job on caring for that car. I know you did well. I would not expect a Tarus to last more than 200,000.

Great video! I am a firm believer in this product. I have seen it first hand. I have an old tractor from the 1960's that I inherited from my grandfather. He was old school and used marvel mystery oil regularly. This was a heavily used engine. So I disassembled the engine and I was surprised that it COMPLETELY clean. I checked the cylinder and crank shaft and they had very little wear. They were still within manufacturer specs. Marvel Mystery oil is the only thing that can explain this. I have continued to use it in all my equipment.
Great info, thanks for sharing.
You make very good videos, and you don't curse like the non-professionals. Thank you, Robert👍
Thanks for watching.
Joseph Veedock I agree!! I can have his channel on no matter who is in the same room!!
I've been using Marvel Mystery Oil in my GM cars and trucks for 38 years...... Low cost engine insurance.
When use regularly keeps your engine running smoothly with less wear on the motor. Just add one quart and fill the rest with oil. Works with both regular and synthetic oils.
Add 6 ounces to a full tank and as the gas pump gets lubrication your also lubricating the top cylinder of the engine.
Thanks for sharing.
You can add 6 ounces of this oil in your full gas tank??
@Ebruhh K. The directions on the Marvel Mystery Oil bottle says to use 4 oz MMO for every 10 gallons of gas. I have a 30 gallon tank on my truck, so the first time that I used MMO, I put 12 oz in my full gas tank. When I refill my tank, I usually put in 20 gallons of gas, so I put 8 oz MMO
frank new awsome. Thanks for info. I have 18gallon tank in my charger (70L). So 7oz i think should be good
Good video!!! Good to see people that doesn't need to use bad words to get their message across.

I'm about the same age as you and sounds like our automotive skill set are very comparable. I appreciate your respectfulness and your tasteful humor as you replied to people posting comments. That says a lot about you as a person. I feel the same way as you about everything you said in the video. New oils are incredible compared to the older oils. I have recently purchased a 1987 Chevy Truck with 83,000 miles that had been setting for maybe 6 years. I bought it from my cousin and know the history of it. A fuel problem is why he parked the truck otherwise it ran fine. I can see some sludge under the oil cap. The oil was really thick when I drained it cold (have not started truck yet... but everything in the fuel system will be brand new after I rebuild the TBI this weekend so will be starting it up soon). I can turn the engine over easily by hand using a socket and ratchet. I have never really used many additives but after looking at a lot of videos like yours about MMO and many other products... I will use MMO in this truck at least for a while. My game plan is... pouring 20% MMO in with conventional oil and a cheap oil filter then running it until the thermostat opens and will drain the oil immediately. Will do this same process again after running 100 miles. Will take a good look a the oil during that oil change and decide what I want to do next. I will eventually run a quality synthetic oil and filter like I do in all my other vehicles. If I can remember to find my way back to this comment I will post the results on how things went. Thanks again for the video. It was nice to watch and read over the many comments.
Thanks for sharing.
Just add a half or a quart with every oil change. So what happened with the 87 pickup?
@@popeantichrist8847 MMO worked great in my 87. I kept using cheap oil, filters and the MMO like in my plan until the oil started coming out clean then switched over to a high mileage oil and quality filters. The truck still runs great. 🙂👍
Robert, the viscosity issue is discussed on the MMO website. I believe it depends on the ratio of MMO:Oil. Here is the statement on the MMO website off their FAQ section: "MMO is about a 5 wt oil. It will reduce the high end number of a multi-vis oil by 4 wt points. The low end number will stay the same when used as per directions."
Thanks for sharing.
mystery oil works . Use it .
Thank you, Mr. Robert. I(and i am sure many other's)truly appreciate how patient & thoroughly well-spoken you're in this educational video. Again, THANK YOU!
You are welcome.
Have used it for 40 years, it works fantastic on older design engines that were made for leaded gas. It will definitely remove carbon build up and lead deposits.
I use mmo in my fuel at every fill up in my 91 suburban. works well and affordable as a every tank additive. very nice video well laid out :)
How much do you add?
@@RobertDIY The instructions say to add four (4) ounces for every ten (10) gallons of fuel.
Hopefully, people are following the instrctions.
Yes sir you are correct. I have used marvel. Since the 70s .
Thanks for sharing.
One of the main ingredients in this product is Castor oil with is highly detergent and has good lubrication qualities..back in the early days of aviation castor oil was the only lubricant used in Radial engines because of its ability to shed heat and resist high temperature break down..MMO is good stuff
Thanks for sharing.
I've been using MMO for at least 50 years, touted initially as, "a BMW mechanic's secret." I've seen it do literal "magic" on at least 2 occasions on different engines in less than 2 minutes. I've recommended it highly ever since I noticed how "interesting" it was from the beginning. When I first got a 2007 Piaggio MP3 250 scooter that weighs 540 lbs. at 5000 miles on the odometer it was getting about 70 MPG. At a little over 10k miles now, the last time I got gas it was getting 95 MPG. YAY, MMO!!! Edgar Cayce called Castor Oil "Palma Christi," and when used a certain way, it "normalizes" adhesions (or scar tissue) in the body fairly quickly. MMO!!! I had no idea it was mostly Castor Oil. Thanks for that info, bro'!
Short answer. YES, this oil additive is very good and can help clean and solve minor problems with your engine such as lifter tick.
Thanks for sharing
MMO BETTER FIX THE CAP ON THEIR BOTTLE. NEARLY IMPOSSIBLE TO REMOVE.

I heard that putting MMO on the threads of your MMO cap will help keep it easyer to screw on and off.
I had to hold it with my knees and use both hands as fellow drivers pass by laughing at my power squat bottle opening stance was in full effect.
It's a child proof cap. If you can't get the cap off, your not old enough to be messing with this stuff.....
Excellent presentation. Thank you. I have used MMO exclusively in gasoline for the life of several vehicles (since brand new until very old). What I have noticed is that it helps prevent wear of cylinder rings. Cylinder compression would stay strong as in a new car for much much longer. A car with 75k miles would feel peppy as if it had only 40 or 50k miles. A car with 180k miles would feel strong as if it had only 100k miles on the engine. I recommend using it ONLY in gasoline in small amounts - 4-6 ounces per 10 galons of fuel. It is OK to add a a liitle bit more than what instructions say.
You are welcome.
Marvel Mystery Oil works best when you FOLLOW THE INSTRUCTIONS on the Label -- just like the video said.
We don't get to make up shit from our own opinions.
I use it in my 96 Polaris SL780 with 305 hours and my 04 Maxima with 226K miles. The jet ski would always start hard and wouldn't idle unless you held the gas a little bit. This mmo has made it run so much smoother with better response and it will actually stay idling. It also makes the VQ35 in my Maxima much smoother, from idling to redline and everything in between. I get about 2-3mpg better when I use it in my gas as well.
Thanks for sharing.
That's why I HAVE TO KEEP COMING BACK TO ROBERT'S CHANNEL. Because when he is explaining something to you.
He doesn't get all technical so that you don't understand. Thanks for your knowledge Wisdom and understanding keep up the good work. 🇬🇧🏁👍

Every other oil change to help keep my engine clean. My car has 233,000 k on it. 2000 Nissan Altima and runs smooth. No problems with my vehicle. I change my oil @ 3000 miles and maintenance is priority.
Wow! That is pretty aggressive. I usually change my oil every 7,500 to 10,000 miles. lol My daily driver has about 367,000 miles.
Me too
3-5000 miles Pennzoil.
This man has old school knowledge and knows what he's talking about. Good info.
About the ATF thing at 8:36.... I remember long ago people use to "clean the valves" by dribbling ATF down the carb holding the engine at high idle. I suppose ATF would loosen carbon build up but I don't know exactly how well. I just know it's a sure way to hydro-lock a motor if not careful.
LOL, thanks for watching and sharing.
I didn't have to take my engine apart to see if there was sludge. I changed the oil and filter and added the proper amount of oil (4.2 quarts), I ran it for about 5 minutes checked the dipstick and it was way overfilled and pretty filthy. Tomorrow, I'm gonna buy me a quart of this. Very informative video.

+Jamie Arrowood cleaning out the coolant.
+Robert DIY It doesn't have any coolant lol.
It does give off a sweet smell and adding to much will really cause it to chooch and smell like a candy factory!
Strange.
MMO actually has peppermint oil in it, so that explains it.
On the Marvel Mystery Oil website. It states that the viscosity is a straight 5W grade oil. Mixed with a multi-grade oil drops the operating temperature number down by 4W levels. For example 20% Marvel Mystery Oil mixed with 80% of 5W-30 would equal 5W-26. Obviously using the correct viscosity oil is critical to longevity. Great video Robert.
Awesome! Thanks for sharing.
Excellent video, Robert. I used this in the past and it does work great. But I agree that it should be used only when needed. You hit the nail right in the head. Again, thanks for the video!
Thanks for sharing.
Robert I worked in auto service from ‘74 to 2007 and you are dead on the money and a true expert from experience, thanks for a great video.
+Jean Brannen thanks for the kind words.
I have been using this for years. I tell you how I measure just the right amount while I am at the gas pump. I use one of those old “stabil” bottles. You know the stuff you use to keep your gas from going bad in the lawnmower. It has a nice measuring feature where u squeeze out the right amount of liquid. But I keep it in the trunk and use it whenever.
+thurm101 cool, that is how I use Lucas fuel injector cleaner.
Great idea
Robert DIY I dump the whole 32 oz bottle in the gas tank around 25 gal tank. Is that ok?
No. That will cause soot and deposits on the plugs. Pour a cap full into the PCV valve once in a while.
William Riley what will that do?
Intelligent and logical reasoning. I think what you said makes total sense. Thank you.
thanks for watching.
Very informative video. I learned a lot.I like how you confirmed for me the ATF trick, I thought I was the only person who did that. AFT is half the price of these auto additives which is good for me.I love using Marvels/Sea Foam every once in a while. I Did an engine flush yesterday with Marves and seafoam Double-Down for 15 mins on high idle. Now my new oil change from the looks of it is the cleanest its ever been on my 132,000 mile car.I know people say this and that about snake oil, but I actually feel a difference in engine smoothness and performance when I do flushes and additives every once in a while.
+Chase Howard Thanks for watching.

we moved to town in January 1959.
Before moving to town, my father tore down both tractors engines every winter and replaced rings but I don’t remember changing out bearings. He would check the bearings. One tractor down at a time. He used MMO with the oil but not with the gas. I use MMO with my gas but use Amsoil full synthetic in my engine. I can see the difference in mileage if I forget to add it to my gas. From what I understand, Amsoil was used as an oil additive in Army aircraft during WWll.
Agreed! Marvel + Seafoam is a great engine flush.
@@donaldhesler3715 WW2 was OVER in August, 1945. Amsoil was not invented until 1972.
I agree with you...I only use it as a fuel additive. And I have used it before and did not drive the car very far and I drained the oil and remove the oil pan...amazingly it does clean and have dissolved the oil sludge
Thanks for sharing.
I would not use marvel mystery in gas tank it's not good for catalac converter and oxygen sensors
makes plenty of sense....recently purchased two used cars for family members and used this product to clean motor before switching to quality oils and filters...unknown maintenance history of them was the prime reason....did not feel it would hurt if responsibly used and could only help....after several oil change intervals with product engines were definitely smoother and quieter. guess I'm a believer in this case.
+matthew rowland nice. I think I'm going to use it in my 740.
is it better than seafoam?
it is supposedly has a gentler solvent and can remain in the oil throughout the change interval, not better perhaps, but works more slowly, which is good, that seems to be the consensus from guys posting on forums on the subject.
matthew rowland fuck that I want that scrubbing action
I use in my gas tank to clean guts of fuel injection system. Never had a problem with fuel injectors. But, did it work? I dont know. The injectors work fine. 270kms. No mechanical issues. I'll continue using it every October before winter snow flies. Plan on keeping my Saturn for 500 klms or more (700 klms). I take care of my equipment.

Subscribed for accurate information. Too many of the smaller DIY channels just do a test and say "works" or "doesn't work" without doing much background research about why you would want or need to use this. You are different, sir.
It was designed to clean and keep clean carb jets. The usage in oil is a by product. It still does a good job, detergents in oil break down, I have seen some dirty modern motors, especially ones with extended service intervals. I would use it as a flush, by adding to oil and letting the car run for 15mins.
+Spac8 Cool, thanks for the info.
Thanks Robert. I absolutely believe in and love this product. They used to have a container that would automtically inject this product into your engine. Keeps the engine running like new.
Thanks for sharing
Thank you for sharing all your knowledge about car and truck repairs. Thank you Robert
History lesson, Marvel Mystery Oil started out as a motor oil for World War 1 radial aircraft engines. In 1923 they started bottling it and calling it Marvel Mystery Oil and adding a red dye. If you use it and today's engines, all one needs to do is about a week before they're going to change the engine oil, when the engine is usually down a half to a full quart, top it off with Marvel Mystery Oil run it for a week and then change oil. It is especially effective at keeping the sieves on the multiple displacement Engine Systems from clogging up as well as making sure that any chain tensioners you may have in the engine continue to work properly. Another use is to add a court during the winter months in cold climates and it keeps the engine oil thinner at the low temperatures so that the engine starts easier, and yet at 200° the oil viscosity is not compromised. It is more than up to the task of helping to maintain be most advanced internal combustion engines that we use in Automobiles, motorcycles and aircraft to this day.
Almost all additives in oils today were around by 1980. It isn't the additives that keep the engine cleaner, it's the detergent. An old-school trick was to put a quart of transmission fluid into your oil for a few weeks before you got an oil change. Because that would help condition the seals, especially the valve guide seals. I've seen engines from the 1960s run 600000 miles. It wasn't the engine that was the problem by the 1960s. It was the suspension system and the fact that the suspension systems were being overtaxed by the larger and more powerful engines that work coming online. Remember that the first GTO had a 400 cubic inch engine putting out about 360 horse and only had 9 in drum brakes that were only 2 in or so wide. Modern engines are not particularly unique, especially with some of the new Engineers that have come on board who never turned a wrench they still sometimes overcomplicate things. When an engine gets overly complicated it is even more incompetent to make sure it stays clean inside. The multiple displacement system has an excellent example. There is no reason to shut off four cylinders to make the engine get better fuel mileage. All you need to do is when the engine is not requiring a load is to cut back on the air fuel mixture. Lean it out to about 11 and 1/2 to 1 and believe me it will get much better fuel mileage than just cutting off four of eight cylinders. You just can't convince Engineers who have absolutely zero experience of this fact.
A further added benefit of Marvel Mystery Oil is adding it to your gasoline at the rate of about 4 ounces per 10 gallons. About 2006 or so they started taking the sulfur out of gasoline. Sulphur was what provided the lubricant for the fuel system and the injectors. In order to replace this lubricant the Marvel Mystery Oil actually works quite well bad actually keeps the injectors cleaner than the sulfur did. I forget how many General Motors products within a few years of taking the sulfur out of the gasoline no longer had a functional gas gauge because the sending unit was worn out from lack of lubrication, not to mention what it did to the fuel pump that by then is in the fuel tank. Do not discount Marvel Mystery Oil oh, I know it has a funky name, but it works better than any other single product that I know.
As for Lucas, it thickens your oil far above what the engine is designed for, and it is also been linked to hardening of the seals in the engine and causing leaks. Use it for lubricating your hinges on your doors but keep it out of the engine.
Thanks for sharing.
@@RobertDIY no problem, I started wrenching on cars in the mid-60s oh, there isn't much new Under the Sun. The same shit that went wrong with cars then still goes wrong with cars today it's just a different device controlling it.
Starting to change now with these tiny engines and tiny turbos. Don't even get me started with the electronics and electric drives.
@@RobertDIY the turbos especially because of the problems you can have in the turbo shaft that continues to spend after there's no more oil pressure almost require something like Marvel Mystery Oil to be used to keep it clear.
My turbo video is getting more and more action. Many of the newer cars also have poor oil supply to their turbos which cause premature wear and clogging. Shame with such an expensive repair.
I have a 2005 mercedes e320 with 200k miles the problem was sticking lifter and stuck valve from a diagnosis mechanic they recommended engine replacement so I added 2 quarts of mmo and a week later the engine runs like new I can't believe it 😳 😀 thanks for the video 👍
Thanks for watching.
robert, i just would like to inform you that all gas stations have a minimum recommended amount of additive in all gasolines. but any branded gas generally has more additive, hence the reason you pay more. you can buy cheap gas and add your own additive, but me personally i like to get costco gas, because they use their own additive which makes the unbranded gas they sell, branded, and top tier. all other branded gas stations have their additive that is added at the rack during loading.
if you ask me how i know this....i haul gas for a living. great video.
+Aaron Johnson Thanks for the info. I do understand, my gas station video is coming soon. In the video, I was referring to early oil supplies, like back in the 30's. I always try to use Top Tier fuels.
That's why I like Chevron gas
@Rob Koch Never have so many words brought such little useful information to so many people.
Thanks for your presentation. Want to share this with u. Sat along side my grandfather when he was retired rebuilding small engines. This was in the 70's. In those days it was called power oil, I think it was spelled differently. Grandpa put it on everything as he rebuilt these small engines. Most of the rebuilds were cement mixers, used in the Tucson, az heat. Have used this products all my life. I am 57 and come from big family, over the yrs my family has asked why my vehicles have lasted so much longer. Good conversation. This is a special product that has with stood the test of time. Take care.

Thanks Robert ! Great video and you obviously know alot through years of hands on experience ! Wish I knew where your shop is so I could take it to someone other than the dealer. I especially like your honesty about whether you use the product or not and analize it's worth through a scientific aspect. You're a very interesting person and I "liked" you and subscr ibed - keep up the good work !
Thank you very much.
Best stuff you can buy for the money don't let the price deter you.
It's cheap.
I use this stuff in my truck, I was talking with my supervisor at work about what was going on with my truck, I told him when I would put regular gas in my truck it would get a real bad spark knock. Well, I told him I hated having to run mid grade gas in my truck because that was the only thing that would make my truck run right. He told me to try some Marvel Mystery oil, I put it in with a tank of mid grade the did it again with regular gas and it stoped like he said it would.
Very good. Thanks for sharing.
I would not use MMO oil in gas tank not good for catalac converter and oxygen sensors
I agree with much of what you say and made those same assumptions, I use castor oil and think this is quality oil. I through my years have always put many miles on my vehicles , now I have a 97 blazer, pull a trailer much and this was a well maintained county truck. at 225,000 miles I changed the oil pan and found much build-up. I use MMO periodically , I now have 300,000 miles. honestly I don't know how well this additive works, I have used it for about 40 years. I love my vehicles, this proves it!
+jim colegrove Cool, thanks for sharing. I guess you could pull the pan every 50 to 100k to see what is building in there.
MMO works great,i use it in gas tanks and other uses like penetrating and air tool oil.
I can keep one product in my garage instead of multiple different products to save room in my toolbox
i typically use Rislone if i have room in the crankcase to free up lifters since Marvel has a higher flammability rate and it thins out the oil a little Which may or may not be desirable.
Vernon Huckleberry hope your garage is doing good!
It's the real deal.l have used this stuff for 40 years, have had 0 problems period.
I never bother with the stuff. I use saw dust myself. Old school but it works to quiet engine down. It doesn't turn either.
Don't use MMO in gas tank it's not good for catalac converter and oxygen sensors
@@Chad-wk2pm It's been tested safe for catalytic converters and oxygen sensors.
See like I have a 1987 Jeep Cherokee Laredo I just inherited and it had 236k miles with a five speed and runs pretty nice, I just want to make sure it’s clean, gonna do an oil change when I add this to oil but it’s going in gas tank right away
Let us know how it effects your vehicle.
it works ive used it in all my cars and lawn mowers i had a mower that popped and back fired i ran this in the fuel and all that quit
Good deal.
From looking at the inside of your engine, it needs some serious cleaning. I switched my 2003 Honda Civic to Royal Purple oil and ATF fluid after 158k miles. The Frantz filter removes the oil's purple color in 15 minutes, turning to gold color. The first oil became dark quickly, so after 4000 miles I changed the Frantz Bypass Filter (Scott 1000 sheet single ply TP) and continued to run the same oil. However the oil was clean but remained dark colored from cleaning out the residue built up over the years.
After 10,000 miles I sent a sample of the RP oil to be analyzed. It came back good to keep using for another 8000 miles with a TBN of 5.1. Even though it looked dark, contaminants were only 11 ppm vs 7 ppm for new virgin oil. I ran MMO for 1000 miles before changing the oil and both filters. The engine is like new inside with only a slight bronze tint to the surfaces. it was well maintained for the first 158k using regular oil changed every 3000 miles. The highway mpg increased from 32mpg to 42mpg. My son switched to Royal Purple oil and ATF in his Honda after using Amsoil for years. He also had a 10mpg increase.
Same for my 2004 1700cc motorcycle that has nearly 40,000 miles. The first 35,000 were on Amsoil MC oil. The inside is bright and clean after the first use of Royal Purple and running MMO for 200 miles before changing oil. Royal Purple is incredible oil, even compared to Amsoil which I won't be buying again. Marvel Mystery Oil is also incredible stuff which I now buy by the gallon.
Wow! Those are incredible results. I think you have convinced me to try RP on my next oil change. Thanks for the info.
I haven't used it in my 97 gmc sierra yet but plan on it. my boss never tuned it up lol having a misfire code. will keep u posted on the after math. I used it to rebuild a motorcycle motor the guy left the spark plug out moisture got in it and piston seized to the cylinder head so rusted I couldn't spin it so i poured it in the cylinder head let it sit for 4 days and it finally freed it up I was very impressed.
+Nate Grunow nice. Thanks for sharing.

It's good stuff! I've used it for close to 40 years. Had several vehicles with noisey valves. Poured some straight into carb, keeping the engine revved. Then the rest in the gas tank. Worked great!
Thanks for sharing.
You're welcome...thanks for the video!
Couldn't agree with you more!
With every thing you said you simply nailed it 👍
Thanks for watching.
Im not going to stop using it it works for me i use it in vehicles in my shop it works great for neglected engines in some cases but it doesnt work for a neglected engine that has already been damaged from neglect or abuse no it wont fix worn out parts but it will clean sludge and fuel systems and boost octane performance with regular use
Thanks for sharing
Preety good review. Why Do I use it. Its like the cheapest product out there that works. A gallon of MMO is around 15 dollars at walmart. I drive a 97 subaru use Mobile 1 Full synthetic. Now I do not as MMO when I do an oil change because Mobile 1 Full synthetic is formulated with special detergents and do not want to mess with that. Now about a week before I do an oil change Ill add a pint of MMO and drive it roughtly 200 miles. I call this my MMO engine flush. Now sometimes I do forget to add this to my gas and I do see my mpg go down abit. But on any given week and driving habit Ill see anywhere from 26-28mpg with MMO. If I dont add MMO ill get below 25mpg. I use it because it works.
+WV Wildlife Cam Great new, thanks for sharing.
+WV Wildlife Cam so you dont use it for oil changes but you use it when you pump gas?
+MatsuriNetwork In my subaru which I use Mobil 1 oil. About a week before I do my oil change I will top my oil off with MMO which is about a half a quart and drive it for a week this is like how a motor flush works.
Thanks for sharing.
Great video and explanation. I've used this product for many years. I put a few ounces in the crankcase a couple of days before my routine oil changes. I really do believe this stuff works great as a cleaner/detergent. Have a great day sir!
Thanks for watching and sharing.
Robert, We use to pour a small cup of MMO right down the carburators a bit at a time. Smokes like hell but man once the smoke cleared did that car run great.
I use this in my fuel and oil in my porsche, HAPPY ENGINE! I also use it in my 8th scale nitro rc car! Great for lawnmowers too...it's good stuff!
Cool, thanks for sharing.
When you add it to gas it lubricates your upper cylinder walls.
Thanks for sharing.
I am a Bitoger and we unerstand that Varnished engines are better helped with the use of synthetic engine oils of the ester type (partial PAO partial Ester) in its base oils. Esters are more polar and solvent, so it attaches to the varnished parts and lift the insolubles out, just like a detergent additive would for detaching, with the advantage of dissolvation and dispersancy, with long term action to remove the deposits slowly to cause not clogging. As a result, at the end of the oil change interval, the oil start to get a hint of the color of the varnish. If the varnish is red, the oil will get a reddish tint, from the dissolving varnish.
+Oscar Flyer cool, thanks for sharing.
i add it to the crank cuz I use cheap oil. 3qt dino 1qt synthetic. I always put some MMO in the gas cuz I dont go to a station that uses premium fuel. THere is a website that lists what stations use premium cert fuel which has more detergents. MMO has unstuck a lifter for me.
+Carl Freiermuth good deal, thanks for sharing.
Great video. I remember even in the early/ late 90s that 100K was high mileage category and 200K the engine ran badly on its last leg. Now my 209K on clock G35 is still running like new, doesn't eat oil.
+Josh Hearn awesome
Alot of alaskan bush pilots use it. They get it by the 5 gallon container.
+crackbadger man Wow!
+crackbadger man . That's correct. Used in a lot of airplane engines.I used to see this around the hanger all the time when I was flying.
+Robert DIY I've actually done that experiment, It does clean the engine! bought a clunker, removed the valve Covers, it was horrendous! sludge was bad! used MMO for four oil changes, removed valve Covers again, and it was near new looking!!
I think the white phospherous is kind of a solvent, and makes the fuel burn a little hotter, cleaner, more complete.
I saw it free a stuck lifter in a truck with 265.000 miles.
This is the kind of Mechanic you want working on your stuff. He does NOT have his head up his own ass and he cares about REAL RESULTS. He also knows the importance of doing proper analysis before drawing final conclusions and that's the kind of Troubleshooting Mechanic we all need.
Too bad the Commercial Automotive Repair Industry fails to hire and maintain real Mechanics like this man. These days, commercial (retail) mechanics are mostly out there devising ways to SCAM the customer by *creating problems that did not exist in your vehicle before you brought it to them in good faith*.
The world needs more Quality Mechanics like this one.
+Whitney Freeway thanks for the kind words.
Great video. It was cool to hear a bit about MMO's history.
If I were to buy a used car with maybe 30,000 miles on it, would you recommend using this to clean it out just in case?
+Yohan Walter No, only if it has been sitting for more than 1 year.
To be honest I thought this was gonna be another "Oh this is the best thing ever - oils are lacking without it" sort of video. I was pleasantly surprised. Good stuff!
thanks for watching.
Great video and info. Very professional. Thanks. God Bless you.
Thank you.
I agree with your takes on Marvel Mystery Oil. Newer cars don't need it and some can be damaged like those with variable valve timing but you didn't mention how good it still is for air-cooled and two-stroke engines. Old motorcycles lawnmowers snowmobiles and snowblowers love it.
Thanks for sharing
Just curious as to how? Nates Interactive shows that MMO has a pretty good anti-wear additive as well as cleaners
@@lonniebeal6032 MMO also stands up to heat and air-cooled engines get very hot. (375F) Diesel truck oil also fights heat well. That's why I use truck oil mixed with MMO in my motorcycles. It works good and is a lot cheaper than motorcycle oil.
BEEN USING MMO FOR 30+ YEARS. I ALWAY HAD GOOD RESULTS WITH IT, IN OIL OR FUEL.
cool, thanks for sharing.
Don't use MMO in gas tank not good for catalac converter and oxygen sensors
I use a little MM in my lawn more gas and crankcase. Very little , and after pulling the spark plug the plug looked brand new. No ash or oil deposits on the plug.
Interesting.
Think he hit on something, In the seventies I did transmission fluid in the oil like he said and if you read up on what MMO does you will probably find out that there is no difference in the two, They both have detergents and seal restoration abilities, we would substitute one quart of Trans fluid and run for 100 miles that would actually restore lifters that were notability Clicking with in that mileage frame
I cant wait to add some seafoam before my next oil change.. is there a chance of having too much volume of liquid if I add it though? Like if my car holds 7 quarts of oil and its full, is adding a can of seafoam too much? Would you recommend MMO over seafoam?
There is no similarity between transmission fluid and Mystery oil except that they both are red. Transmission oil is formulated on a base of 10-weight oil. Mystery oil is heavy naptha and turpentine with a some additive that basically are glorifed mothballs. Both will help flush an engine before an oil change but they are not whatsoever the same thing. My recent researches have determined that all solvent additive are just about the same thing - naptha and turpentine. You might as well use Mystery Oil for everything - engine oil and fuel sytem. It's as good as anything and a value for the price. You can get a quart at that big box store for less than $4.
Great Product, I've used it since 1975, substituting one quart oil with MMO in gasoline and diesel engines oil changes. In Diesel I ran it in the fuel as well and never had injector related issues friends had. But where it really shined was in my F250 Super Duty, Ford had a class action law suit filed against them because the 5.4L triton engines would rap a couple of times on cold days when initially started because of a design flaw in the length of the piston skirts. My Super Duty Never experienced this until one oil change that my local Autozone was out of MMO and I only had synthetic 5W30 in the crank case. Because MMO is like a light machine oil, it thins your motor oils viscosity and when cold your oil system pressure rises faster and your engine is less oil starved at startup. I have not missed putting MMO in my oil since, even in my C7.
Thanks for sharing.
Don't run MMO oil in gas tank bad for catalac converter and oxygen sensors
One thing to consider using this or even switching to synthetic oil is cleaning the engine out and creating an oil leak you didn't have before. Happened to me when I used synthetic oil and got a rear main leak a few weeks later.
+Paul Lott You do realize that means your rear main was bad before the switch to synthetic, right?
+Paul Lott Ouch! That can happen.
+nilphuxgiven yeah I do, and i fixed the problem.. most people who may use this junk could create the same problem and may be unable to. my original comment was more of a warning..
+Metal Detecting Winston Salem, NC - So in your case, it became a Mystery? LOL
Agreed. If an engine has been neglected, run on dirty oil, dirty air filters, you may have worn seals and the metal where the seal rides on.
Nice work on this video. Great information to have. I have a 97 Wrangler Tj 2.5 with a tapping sound when she starts up. Takes a little bit for it to go away so I figure it needs a little love. This may be just the stuff.
Thanks man!
Hope it helps
Sounds like you might have a faulty Anti-DrainBack Valve (ADBV).
For maximum protection of your Wrangler's 2.5-liter engine, I recommend the BOSCH #3402, or the FRAM #XG16. Pennzoil Ultra Platinum @ 5-W-30 (Year-'round), and Oil & Filter changes at 5,000 miles.
Marvel Mystery Oil works great, use it in my cars, use it mixed 50/50 with alcohol to recharge my k&n filters, mix it with mineral spirits as a penetrating oil, use it for air tool oil, great stuff, GO STEELERS!
+Since73 thanks for sharing.
You are NOT "recharging" your K&N Air Filters with MMO/Alcohol -- you have ruined them.
WHY in the Holy Hell do people INSIST on NOT following the MANUFACTURER'S DIRECTIONS !??
Seems like every hillbillie and his ignorant cousin have found a "cheaper" substitute for automotive products, and they HAVE TO tell us how well it worked -- for them.
@@SlikLizrd you do know the oil k&n uses is mineral oil, which is what mmo is based on, and yes I have been doing it that way for over 20 years, with no issues. but thanks for playing
@@TheBgred1 You're ASSuming that all mineral oils are THE SAME. They are not, and are NOT interchangeable.
You've been doing it WRONG for 20 years, which is nothing to brag about ;>)
@@SlikLizrd tell that to my cars and the filters they’ve been running for 20 years, seems to me you’re the one ASSuming 🤷🏼♂️, you shouldnt talk about what you dont know, or understand.
I use this for about 20yrs .. added to my oil and gas .. this works .. best on the market ..
+august van suchtelen thanks for sharing.
MMO: Swear by it or swear at it; added to fuel, it lubes the fuel pump and the injectors.

I could tell you have been around for long time to know some things in the past and how times and things have changed. Younger people mostly don't know these things because of not working on things. Hands on. You know. Cars like you said if they have 100,000 k the was a good life for the car. Now cars are made much better and last longer. And the quality of Oil's filters have improved over the years etc.
+William E True, thanks for watching.
Great Video! Very informative. Thank you for sharing your knowledge.
You are welcome.
this add oil is a marvel..i used it to doctor a '97, f i, 1.8, 4cylinder engine, right away the engine smoothed out..the viscosity came up from 10 40, obvious higher compression, the additive loosened up and lubercated the valve function, i put various amounts into the tank and it seemed to lubercate and clean the entire fuel system which includes the fuel injectors..excellentstuff...periodic use, 2-3 times a month..
Wow! Thanks for sharing.
I agree with your statements that the only definitive proof of a product working- is a complete teardown before and after usage, and closely examining the wear surfaces and areas that usually harbor buildup. Personally- I always flush the engine with 1 quart of kerosene, high idle @1,500 RPM >10 minutes, and drain hot- and always change the filter.
+HUBBABUBBA DOOPYDOOP thanks for sharing
Kerosene as an engine flush !??
The stupid never stops !!
Kerosene belongs in a lantern, NOT in an engine.

Wow. Another 4 Subscriber, ZERO content Troll.
Most "Engine Flush" products are mostly kerosene.

Thank you very much -- for proving my point.
Although many of these "Engine Flush" products CONTAIN SOME kerosene, kerosene is NOT the primary ingredient in Marvel Mystery Oil -- as was shown by your so-called "Creators".
Perhaps you should stay in your lane to avoid being run over. ;>)
@@SlikLizrd
A "Creator" here on TH-cam, is a designation of a person who
has produced, uploaded and published a video. Never having
performed that before- I can see why you'd struggle with that
concept, and make some fun.
Not once in my first statement here- write that I believe MMO
contains a fraction of kerosene. I don't know how you derived
that. Please show us where? Show or STFU.
No, you're correct- I don't drive on the shoulder of TH-cam.
That's for Folks who've broken down & having trouble, like you.
I've used MMO in my Gas in older Volvos and certainly made the engine seem to run smoother.
Nice, I may try it sometime.
MMO oil is not good for catalac converter and oxygen sensors
I like the Steelers hat.
+Dave Knepp thanks. A Bengals player purchased it for me. 😂
Thanks for sharing this information, Robert.
And just for clarity at the 5:40 mark, when Robert says "today's car engines that were designed in a decent fashion".....translated, means "every engine on the planet that HASN'T been built by Chrysler Corporation".
lol, Man, don't leave that comment on my page. I don't want a bunch of Mopar people on here blasting my channel. ;)
Well I put MMO in my truck about a month ago, 159k miles on my 98 f150 and It stopped my slow oil leak, I would have about 1/4 of my oil missing every full tank I go through so every full tank I would add oil. It stopped the leak it has been only a month but its been through a couple of gas tanks full and the oil level is still topped off. I added just a little bit of MMO not much but I only added it once and it seems to be doing well!
+bax1231 Very nice. Thanks for sharing.
i use this in all motors and my air compressor i can say this my motors do not blow up and i drive em hard
i agree with this guy Never had a ever a major failure using this stuff
+MICKIN310 thanks for sharing
Can this be used in any oil? For instance my manual transmission takes automatic trnsnission fluid, would i gain anything from putting this in a manual trans, or is it just for engines?
+moneyhungryyt I doubt it but read the label, it will tell you.
I wouldn't, but what do I know.
Thanks for all the detailed information! I love listening to detailed informative videos! Glad you touched on so many different impotent pieces of information regarding oil!
Thank you for watching.
First off, i dont know if it or any additive really does its job.
One thing you have repeated and rings true over your videos is "Propper maintainance", that is the best advice any car owner needs, its 100% true and logical.
That marvel product ive never seen before, but it makes me worry about there instant milk powder ha ha :-D, does it make your tea/coffee wash off the cups easyer :)
+zx8401ztv I took it back to the store and got my $4 back. LOL
+Robert DIY HA HA you borrowed that from the shop didnt you :-D
LOL, I guess we can call it that. LOLOLOL
+Robert DIY Just imagine how pissed off you would be if he said "no refund", your stuck with your video prop :D
Ive allways thought that estate agents were sneaky, you just confirmed it LOL :-D joking of cause :)
Here in the US they call it Snake Oil. LOL
I use it as a lead substitute , to lubricate my pan head top end . Been using it for 20 years. It works on old engines for sure .
Thanks for sharing
Used it in my son's old truck that had a valve tap added it to the oil. 2 days later tap was gone . do you know what's in Marvel Mystery Oil ???????????? I don't Either that's why its called Mystery Oil
LOL
I fry chicken in mystery oil yum yum
Tasty dipping sauce.
Salad dressing, BBQ glaze, shaving cream
Dave Sysygy lol it does smell pretty damn good
Great review i have a 2024 chevy Trax 2RS and i put it in my car i don't go crazy putting it in my crank case it makes it run smoother also i do put in my gas moderation is the word.
Interesting
Good info. Thanks.
Great video. I really appreciate your honesty. Thank You for your time and input
you are welcome.
you are a pro sir
Thanks for watching.
Have used the stuff in fuel as directed and sometimes added to oilnot long before a change. Never hurt anything, but can't prove that it really helps as I have never had problems that would require it.
