Wow, a whole gallon of Marvel Mystery Oil all at once seems like way too much. I hope it doesn't hurt your catalytic converter or O2 sensors. I have been using MMO at every fill up in my car, truck, and lawn mower since 2016. I use the recommended amount of 4 ounces of MMO for every 10 gallons of gas. Since I have been using MMO, my car gets at least an extra 1.5 to 2 more miles per gallon on the highway.
It's definitely not recommended to use the amount I did. I just wanted to make an entertaining video. Surprisingly it did not harm the car at all and it's running just as good as it was.
@@kingdz7818 just because a gallon was poured in doesn't mean it will smoke. It's not like spraying seafoam into the intake or something. It's a direct injected engine. If it were port injection, then it may smoke a little because of the extra MMO cleaning off the runners and back side of the valves.
Don't try this at home, kids. More certainly isn't always better. In fact, it can make things worse. It's not going to necessarily hurt your engine, but enough of this stuff will poison your catalytic converter over time if used in excess. Just follow the directions on the bottle.
Way back when we had 30W oil we would add a quart of MMO to the crankcase in winter. It would thin out the oil for easier starts in winter. Four quarts 30W 1 quart MMO. We would also put it right down the carburetor for cleaning. Smoke like hell got a lot of middle fingers but it was excepted.😂😂😂😂
You drove to the gas station after dumping the mystery oil. Oil is heavier than gas so most of it sank immediately to the bottom of the tank and a percentage of it was presumably sucked directly into the fuel pump on your way to the gas station, the percent would depend on how far away it was and how aggressively you drove. This is why the instructions say to wait till the tank is almost empty and fill the tank immediately after adding the MMO so that it will be mixed by the fuel stream entering the gas tank when refueling.
MMO is one of the few additives where I also feel like it's a touch smoother, seems like the engine is more lubricated. It's a slight effect one might pin down to placebo but going back to a tank of gas with no MMO in it I always notice it feels a bit rougher.

If I ever find one in decent condition, I would probably buy it if it wasn't over priced. I love the way it looks.
In my 2004 Chevy Trailblazer EXT LS 5.3L ONLY 6oz to a full tank of gas. During an oil change ONE QUART ONLY in the crankcase and fill with your preferred oil Conventional or Synthetic works with both. 175k Miles still running like NEW. I also use it in my 2019 Hyundai Sonata SE 2.4L with excellent results.
I want to try this. How often do you change your oil and do you use the stock oil recommendations or go 1 up higher Due to diluting the oil like how people say. For example on a car that takes 0w16 would you use 0w16 or 0w20 5w20? Sorry for bad English. And how often would you change it. Thank you.
@@wevonox7941 I use either Mobile One or Penzoil both 5W30. I've also used synthetic blend like Kendal Titanium 5W30 always a quality oil filter. I drop the oil every 4,000 miles for engine longevity. Never blew an engine following this schedule
MMM is great for the crankcase oil. But, of all the products I have added to the fuel tank, 2 cycle TC-W3 oil did the best to quiet noise lifters (tick-tick-tick) on 2 of my high mileage vehicles. It happens on cold winter startups on a 2.5L Ford Fusion and a 2.5L LIMA Mazda B2500. The TC-W3 oil really reduced and almost eliminated it. I use it in all my vehicles. Excellent startups. They run great. Here is the info: 2stroke MARINE TC-W3 oil has been used as an upper cylinder lubricant and cleaner for decades. It is designed to be burned in a combustion cylinder and leaves little to no residue. It is used at a 1 oz to 2 oz per 10 gallon of gas ratio. It does a great job of cleaning intake valves because of its high levels of detergent while lubricating the valve stems and seats. Since it burns without ash. It will not clog a catalytic converter. Over time, it can open up dirty intake valves and improve efficiency. It also acts as a lubricant for injectors.
@@atwoodfitness3438 Well, if it is good enough in high concentrations (40:1, for example) in 2 cycle engines, then the lower concentration in car engines will be just fine. I put some in my Father-in-Law's HEMI Hellcat. It sure liked it. 🙂 My Honda engines liked it, too.
I have a question for you? How does adding something to the fuel affect the lifters since the fuel doesn’t go anywhere near the lifters? Did you mean you put the 2 cycle oil in your oil?
@@ohboy2592 I had the same conversation with my friend this weekend; folks get lifters and fuel knock/ping confused as they can sound similar. If you use ethanol fuel in a old rig, depending on your timing, it can knock bad for a bit until it heats up since flashpoint and BTU is different than straight gas. Modern cars can electronical adjust timing but sometimes it not enough. MMO, ATF+4 or 2stroke oil in both the fuel tank and crank case is great as it will clear up valve train issues such as loud lifters and will help treat ethanol fuel so you don't have fuel knock + lubricate and clean. I make a mix of MMO and Lucas oil additives; one for fuel and one for oil since Lucas has different additives for both.
Another excellent example of why engineers get old and lose their hair! Engineers spend decades learning, creating and refining all sorts of products and processes. They write instructions to optimize user experience and (in this case) vehicle longevity. You can be SURE the mfgrs of MMO want to sell more MMO - all that they can... but not at the risk & expense that likely will occur from overuse. When enginerds came up with the ratio of 4 oz to 10 gallons gas, you can be sure they had very good reason for it.
Back in the 80s , I had a 4cyl Camry. I would put a 1/2 quart in to every oil change, accumulated over 400k on that car, sold it to a neighbor and it’s still going strong, 2024 without any engine issues
The good thing about MMO is that i believe it will lube fuel pumps, which is a must when the freaking things are inside your tank. These pumps need all the help they can get.
I agree with you 100%. Back in 2016, I had to replace the fuel pump in my 2002 Chevy truck. The mechanic who replaced the fuel pump said to use some Marvel Mystery Oil in the gas and it would lubricate the new fuel pump and it would last longer. I also started using MMO in my car, and both vehicles are running better than ever. My car now gets at least an extra 1.5 to 2 more miles per gallon on the highway.
your car is new try it on a neglected chevy astro van with say like 120 000 miles . preferably with a ticking noise (lifters ticking) and put it in both gas and oil ,,,after driving it like 3 oil changes with this stuff the stuck lifter will be free and the noise will go after that experience i became a believer it even got quicker and throttle response at any rpm became unbelievably more alive i was like shit this thing can haul ass now
@@trikeonabike4949 good luck then , then its 4oz per 10 gallons gallon about 320mils converted to metric or 4 oz multiplied by 27/10 = 2.7 so 4 * 2.7 = 10.8 oz (320ml)
Thanks for doing this as all of us MMO users always wonder did I add too much? I have a 26 year old Harley I run a mix of MMO and Sta-bil and non ethanal pure gas in every tank the last 25 years. I always keep the tank full when parked and I have never has a fuel related problem. Replaced and upgraded the carb 25 years ago and still runs strong and no rebuilds. You can actually feel the MMO when I turn the gas on and off ( Petcock ) as it keep the o-rings smooth as silk. I don't use MMO in new cars with catalytic converters but after watch this video why not? What could a little hurt every now and then?
Well; been using it for over 50yrs. But what you did, you may have made the fuel to rich. And you didn't pull the spark plug out before the test to see about carbon issues. Marvel doesn't create carbon. What it did perhaps, is clean out the fuel system. Marvel, in what it does, help's protect top cylinders & fuel system... I add about 1/3 of a quart in my truck 1999 F150 with over 214,000 miles. People forget this; we use to have Leaded Fuel until 1975. Engines at the time with Unleaded Fuel were having issues because Lead in Fuel acted like lubricant. I had a 1969 Ford Mustang until the yr of 2000 but it had over 253,000 miles on it. And Marvel was its lead substitute protected the top of the motor.
I had a Dodge with a 360 motor that's sat for a while had sticky valves ticking like crazy changed the oil drove it around for 100 miles nothing happened I drained a quart put a quart of marvel mystery oil in it went away in like 5 minutes left it in everything ran beautifully.
I think I may have put too much in a 86 Ford im restoring. It won't run on the tank with the mmo in it. I'm going to throw some octane booster in it to try to get it to burn but if not I'll be taking it out and diluting it for the lawn mower and maybe my truck.
In '03 I ordered a Jeep Rubicon and less than 10k miles later it developed an intermittent miss. After several years and multiple dealer mechanics one told me of jeep TSB 09-003-03 which had the exhaust valves getting crudded up and sticking open. The only thing that would free up the valves was MMO or Marvel Mystery Oil. Today's MMO is a different formula but my Jeep needs a tank of gas with it every 5k miles or so. At 107k miles the engine still runs fine, no misses after treatments when needed, and no damage to the emissions system. I have never used it in the engine oil. My Dad would have called it snake oil but, dang it, this stuff works...
What people don't realize when using it is when it cleans off the carbon from like the cylinders , that residue goes to the exhaust valves so. Think of it as when you sweep your floor. All the dust an whatever goes from one spot an moves where ever you are sweeping towards. With my bird it took 4 fillups to clean even my exhaust valves with MMO plus i added v power which helps alot too.
You should have poured it in the gas tank at the gas station. While driving there if you were at half tank you were basically driving on 2 gallons per tank ratio. If it was quarter tank that would be 4 gallons per tank ratio. However, nothing catastrophic happened. I think that made the plugs oily looking and weirdly fouled. Run that tank and then fill up. Then clean all the plugs. It might run even better all lubed, clean injectors and plugs.
I did the same with my 27 gallon tank on my 2007 Chrysler Aspen, I toke advantage of a 300 mile trip that I needed to do and usually a full tank in the highway gets my 260 to 280 miles so I poured the complete gallon and drove non stop from McAllen Texas to San Antonio 65 to 70 MPH ...the San Antonio back to McAllen the same day....WOW! this thing change my Aspen a LOT!! the 4.7 V8 runs smooooooth amazing stuff, everything improved, a little gas millage, this thing gets me 22 MPG at 70 in the HW, IT increased close to 25 MPG!! NEVER SINCE I PURCHASED THIS ASPEN IN 2007 NEVER I HAD 25 MPG! IM IMPRESSED AND HOCKED FOR LIFE WITH THIS THING "MISTERY OIL" Sound like snake oil but fricking thing did something, I just hope it didn't affect the Catalyzer and oxygen sensors, on the way Back I filled up the tank with EXXON SUPREME .... So today is about 2,000 miles since I did that an it still running very smooth....
That is way too much Mystery Oil to be putting in a brand new car these modern cars don't take that much follow the instructions on the back 4 oz in the gas tank and like 8 oz in oil don't have to do that don't ever put a whole gallon in there you will destroy your car unless you're trying to flush it out and you're going to drain it out within the same day
Bottle says, "replace up to 20% of oil with MMO..." meaning a 5 quart system should only use UP TO a full quart of MMO. Some people just don't know how to read instructions 😂
In older carbureted engines, using mmo in gas at recommended mix ratio did clean carbon off valves, and upper cylinder walls, piston rings. It also lubricated upper cylinder rings and walls. Today it lubricates and cleans the same upper cylinder rings and cylinder walls through the injectors and cleans the fuel injectors. I would only use ratio advised. Not a whole gallon to a tank. Mmo is decades old.
This is strange. What was wrong with the car to want to put that much oil in the tank? Sounds like he is trying to fax something that isn't broke. I can see why there is carbon build up. Plugs aren't designed to burn oil. Crazy.
Even though the video is primarily meant to be entertaining, I really did pour a full gallon of MMO in the gas. I was a bit curious myself though I did risk damaging the car. To my surprise, it did not effect the car in any negative way that's perceivable. So many people believe that it has caused damage to my car which is interesting to me because it shows how people hold on to old or wrong information. Not that I'm saying it can't, or won't damage anything, it's just not guaranteed by simply overusing it at least once. Yay science! 😅
It probably was a tad faster only because Marvel Mystery oil is harder to burn then gasoline so it was basically an octane booster it reduced the chance of detonation which your car has knock sensors especially being turbocharged and your computer probably added more timing and more boost. But I appreciate you doing this because I've added a half quart to my daily driver before and wondered how much was too much I guess I'm definitely good LOL
Hey Track pack GT, I may have happened to made a dumdum yesterday....literally probably the first time in my life I didn't read the instructions over and over of something I'm putting in my car..I'm usually crazy careful about anything I add but yesterday my dumbass just assumed marvel mystery oil was like every other fuel additive and takes the whole bottle. Anyway I added 16 oz of it to my tank in my Charger when I filled up the tank with right under 18 gallons of gas. After everything I've been reading online I'm super nervous it's gonna damage something. Wanted to ask you what happened with yours after adding a whole bottle by accident. Did you have any problems or did it run like it always did? Hope you get this and send a response lol
@@davidhuffman8543 I've put a half quart in 20 gallons of fuel the truck didn't even notice it nothing happened a quart to a whole tank no big deal it'll be fine bro just drive it Marvel mystery oil burns it's just harder to burn than gasoline you'll just have a really clean fuel system and injectors and cylinder LOL but it won't hurt anything. If you're really worried about it after a couple days top off your fuel tank again to dilute it more but I'm sure it'll be all right
@@trackpackgt877 that definitely makes me feel a heck of a lot better lol I've only used probably less than 2 gallons of gas since it happened and it does feel like it doesn't have as much power as usual but it's nothing major, but it is definitely putting out some smoke out my tailpipes. It's not a crazy amount but it's definitely noticable. I appreciate you responding to me... can't tell ya how much I been stressing over it lol was debating real hard about pulling my back seat out and opening up one of my fuel pumps to start pumping that fuel out lol
@@davidhuffman8543 I'm not surprised it's smoking with that much in it you're basically running two-stroke fuel right now so smoking is normal it's just burning it off I would just run it for a few days and put some fresh in it thin it down.
It's said to be better if you do it before an oil change. The reason why is because the cleaner will dissolve carbon build up and that will make it's way into the oil. Using a cleaner after a fresh Oil change will likely cause the oil to darken much quicker. Not to say it would ruin the oil, but it's better to do it before an oil change for that reason.
You won't really notice any improvement on a nearly new low mileage vehicle. Its really for use on a high mileage or poorly maintained vehicle to clean, restore power and smoothness.
Be advised, newer vehicles with O2 sensors and cat converters may not do well with oil of any kind in the fuel system. Saying that I use MMO in every engine I own. Cars, trucks, generator, snow blower, lawn mower. It keeps seals soft and sealed. It fixes moderate blow by problems. It can even restore old motors compression issues. 50 years it's never let me down.
I think the idea is that you thin out the oil and it works better that's why some of the cars went from 10 w 40 to 5W-40 and then now it's 0w-40 or 0w 20
You can put a meter in your windshield or something and it'll measure the g-forces when you accelerate and maybe that way you can tell the difference if it really gives you some extra horsepower or not you can like do it like on a quarter mile or something
Berryman B 12 is the best I've ever used for fuel economy because it has acetone in it. With Berryman B12 fuel injector cleaner you have to follow the directions 100% though or you could do damage to your vehicle.
@ williamperri3437-- I have heard good things about Berryman B-12 Chemtool, but it seems that it is very strong and harsh. Even though I use MMO on a regular basis, I bought several cans of Berrymans from Walmart. My 2002 Chevy truck has a 30 gallon gas tank, that has 165k miles on it. Since it has a 30 gallon gas tank, I added two cans of Berrymans at my last fill up. It's too soon to tell what benefits it will do, but I was wondering how often you use it. Since Berrymans seems so strong, I was thinking I might use it once or twice a year, or about every 5,000 miles.
I put Berrymans in my 3.4 liter V-6 Impala every 2nd tank of fuel for a year. Follow directions on can though. At 75,000 mi. had sparkplugs, spark plug cables replaced. Engine is quiet.
Fuel stabilizer like MMO and Stable I thing it’s spelt STAY BL, that stuff is literally not only good for the engine, but it’s like nos. I put it in my bike and my truck, made both more responsive and sound smoother. But too much can and will clog by foaming up
best when used before a long trip. IT DOES WORK! around town it may foul your plugs. Its LINSEED oil which is an incredible astringent =CLAEANER. but it has to get HOT TO WORK! Dont use in winter months. just mho
It could be good like a cleaning the fuel injectors and cleaning the carbon in there around the piston rings it could actually work but I wouldn't imagine it would add that much
Buy a quart give it a try in a few full tanks. Marine outboard two cycle TCW3 rated oil in your car. You won’t know the car is running at idle. You can use Walmart or any other marine outboard TCW3rated oil. It burns ashless so no harm to sensors or converters. Works like MMO or Lucas fuel conditioner but cheaper and better. This is why two cycle engines last so long.
I think the gas companies are supposed to be put in that kind of additive in their gas something and they don't add any more than they think well actually work otherwise the gas companies would put that in there and sell it to the public the engineers and researching design probably test it all that stuff out before but they never really tell us because it's a trade secret so they can have something better than their competition
Anytime you add oil to fuel, it will leave carbon deposits on the pistons. After that tankfull, put a borescope down a sparkplug hole. Carbon raises compression and requirment for octane. More is not better.
It's can't be true 🤔 it would definitely change the chemistry of whole tank. Spark plugs should be oily. Car might gonna run Lean or Rich(probably leaner and hotter). If it's really true it was probably running so lean and hotter and oily substance burned tight off from the sparkplugs. I over treated once with seafoam+mmo but that was not even close to 1 gallon lol and I found my sparkplugs were oily after 350 miles. I don't know man but oily substance definitely not good for catalytic converte.
I put a quart in think in New Jersey the gas at the pump 87 regular at a gas station was bad..have to wait and see probably fuel injectors aren't going to need professional cleaning I'll wait a tank too with this stuff
Dude that's WAYYYY TOO MUCH !!! I added over 3 bottles of Lucas injector cleaner to my cargo van thinking that more is better but it messed van up and I had to change all my oxygen sensors plus go through 2 tanks of gas before van drove normal
As Bugs bunny would say " What a Maroon" what about the exhaust system, cat converters , O2 sensors , do not use this MMO in a modern ICB automobile, every engine air/fuel mixture is computer controlled. MMO is a good penetrating oil for cleaning/freeing rusted parts.
Actually they say: “too much of anything, even a good thing is bad for you .” - Captain James T. Kirk And if Kirk said it you can take that sh*t to the bank, because it is gold.

You should have checked the compression to see if the Marvel increased compression? of course check compression before pouring it, and taking notes

It happens on cold winter startups on a 2.5L Ford Fusion and a 2.5L LIMA Mazda B2500. The TC-W3 oil really reduced and almost eliminated it. I use it in all my vehicles. Excellent startups. They run great. Here is the info: 2stroke MARINE TC-W3 oil has been used as an upper cylinder lubricant and cleaner for decades.
It is designed to be burned in a combustion cylinder and leaves little to no residue.
It is used at a 1 oz to 2 oz per 10 gallon of gas ratio.
It does a great job of cleaning intake valves because of its high levels of detergent while lubricating the valve stems
and seats. Since it burns without ash. It will not clog a catalytic converter.
Over time, it can open up dirty intake valves and improve efficiency.
It also acts as a lubricant for injectors.
I've actually been thinking about this but been nervous as hell to try it
@@atwoodfitness3438 Well, if it is good enough in high concentrations (40:1, for example) in 2 cycle engines, then the lower concentration in car engines will be just fine. I put some in my Father-in-Law's HEMI Hellcat. It sure liked it. 🙂 My Honda engines liked it, too.
@@thomasszilagyi7445 I'm wanting to put it in a Chevy Cruze
I have a question for you? How does adding something to the fuel affect the lifters since the fuel doesn’t go anywhere near the lifters? Did you mean you put the 2 cycle oil in your oil?
@@ohboy2592 I had the same conversation with my friend this weekend; folks get lifters and fuel knock/ping confused as they can sound similar. If you use ethanol fuel in a old rig, depending on your timing, it can knock bad for a bit until it heats up since flashpoint and BTU is different than straight gas. Modern cars can electronical adjust timing but sometimes it not enough. MMO, ATF+4 or 2stroke oil in both the fuel tank and crank case is great as it will clear up valve train issues such as loud lifters and will help treat ethanol fuel so you don't have fuel knock + lubricate and clean. I make a mix of MMO and Lucas oil additives; one for fuel and one for oil since Lucas has different additives for both.
Another excellent example of why engineers get old and lose their hair! Engineers spend decades learning, creating and refining all sorts of products and processes. They write instructions to optimize user experience and (in this case) vehicle longevity. You can be SURE the mfgrs of MMO want to sell more MMO - all that they can... but not at the risk & expense that likely will occur from overuse. When enginerds came up with the ratio of 4 oz to 10 gallons gas, you can be sure they had very good reason for it.
Back in the 80s , I had a 4cyl Camry. I would put a 1/2 quart in to every oil change, accumulated over 400k on that car, sold it to a neighbor and it’s still going strong, 2024 without any engine issues
The good thing about MMO is that i believe it will lube fuel pumps, which is a must when the freaking things are inside your tank. These pumps need all the help they can get.
I agree with you 100%. Back in 2016, I had to replace the fuel pump in my 2002 Chevy truck. The mechanic who replaced the fuel pump said to use some Marvel Mystery Oil in the gas and it would lubricate the new fuel pump and it would last longer.
I also started using MMO in my car, and both vehicles are running better than ever. My car now gets at least an extra 1.5 to 2 more miles per gallon on the highway.
It’s 4 oz per 10 gallons, not sure where you got 2 ounces
Maybe he only adds 5 gallons at a time so just needs 2oz at a time 🤔
Read that 6oz is acceptable for a particularly dirty fuel system. Used between 4-6oz during my initial testing of MMO
your car is new
try it on a neglected chevy astro van with say like 120 000 miles . preferably with a ticking noise (lifters ticking)
and put it in both gas and oil ,,,after driving it like 3 oil changes with this stuff the stuck lifter will be free and the noise will go
after that experience i became a believer
it even got quicker and throttle response at any rpm became unbelievably more alive i was like shit this thing can haul ass now
🤔 hmmmm
I have a GMC Safari (literally the same thing, different name), though not neglected- its just old- about to try this stuff out myself...
@@trikeonabike4949 good luck then , then its 4oz per 10 gallons gallon about 320mils converted to metric
or 4 oz multiplied by 27/10 = 2.7
so 4 * 2.7 = 10.8 oz (320ml)
Thanks for doing this as all of us MMO users always wonder did I add too much? I have a 26 year old Harley I run a mix of MMO and Sta-bil and non ethanal pure gas in every tank the last 25 years. I always keep the tank full when parked and I have never has a fuel related problem. Replaced and upgraded the carb 25 years ago and still runs strong and no rebuilds. You can actually feel the MMO when I turn the gas on and off ( Petcock ) as it keep the o-rings smooth as silk. I don't use MMO in new cars with catalytic converters but after watch this video why not? What could a little hurt every now and then?
Well; been using it for over 50yrs. But what you did, you may have made the fuel to rich. And you didn't pull the spark plug out before the test to see about carbon issues. Marvel doesn't create carbon. What it did perhaps, is clean out the fuel system. Marvel, in what it does, help's protect top cylinders & fuel system... I add about 1/3 of a quart in my truck 1999 F150 with over 214,000 miles. People forget this; we use to have Leaded Fuel until 1975. Engines at the time with Unleaded Fuel were having issues because Lead in Fuel acted like lubricant. I had a 1969 Ford Mustang until the yr of 2000 but it had over 253,000 miles on it. And Marvel was its lead substitute protected the top of the motor.
I had a Dodge with a 360 motor that's sat for a while had sticky valves ticking like crazy changed the oil drove it around for 100 miles nothing happened I drained a quart put a quart of marvel mystery oil in it went away in like 5 minutes left it in everything ran beautifully.
Bro... me too ... several times lol 💪
I used MMO on my Suzuki's noisy power steering pump. Since last year my power steering pump has been quite and the steering is smoother than ever.
*q-u-i-e-t
Any issues with that Power steering pump after time with the marvel?
@@ryanderks7382 No, no at all.
I think I may have put too much in a 86 Ford im restoring. It won't run on the tank with the mmo in it. I'm going to throw some octane booster in it to try to get it to burn but if not I'll be taking it out and diluting it for the lawn mower and maybe my truck.
Thanks for doing this. I had always wondered how much was "too much", but didn't want to risk my car...
Try using twice the required oil in the crankcase, and report back.
In '03 I ordered a Jeep Rubicon and less than 10k miles later it developed an intermittent miss. After several years and multiple dealer mechanics one told me of jeep TSB 09-003-03 which had the exhaust valves getting crudded up and sticking open. The only thing that would free up the valves was MMO or Marvel Mystery Oil. Today's MMO is a different formula but my Jeep needs a tank of gas with it every 5k miles or so. At 107k miles the engine still runs fine, no misses after treatments when needed, and no damage to the emissions system. I have never used it in the engine oil. My Dad would have called it snake oil but, dang it, this stuff works...
What people don't realize when using it is when it cleans off the carbon from like the cylinders , that residue goes to the exhaust valves so. Think of it as when you sweep your floor. All the dust an whatever goes from one spot an moves where ever you are sweeping towards. With my bird it took 4 fillups to clean even my exhaust valves with MMO plus i added v power which helps alot too.
You should have poured it in the gas tank at the gas station. While driving there if you were at half tank you were basically driving on 2 gallons per tank ratio. If it was quarter tank that would be 4 gallons per tank ratio. However, nothing catastrophic happened. I think that made the plugs oily looking and weirdly fouled. Run that tank and then fill up. Then clean all the plugs. It might run even better all lubed, clean injectors and plugs.
I did the same with my 27 gallon tank on my 2007 Chrysler Aspen, I toke advantage of a 300 mile trip that I needed to do and usually a full tank in the highway gets my 260 to 280 miles so I poured the complete gallon and drove non stop from McAllen Texas to San Antonio 65 to 70 MPH ...the San Antonio back to McAllen the same day....WOW! this thing change my Aspen a LOT!! the 4.7 V8 runs smooooooth amazing stuff, everything improved, a little gas millage, this thing gets me 22 MPG at 70 in the HW, IT increased close to 25 MPG!! NEVER SINCE I PURCHASED THIS ASPEN IN 2007 NEVER I HAD 25 MPG! IM IMPRESSED AND HOCKED FOR LIFE WITH THIS THING "MISTERY OIL" Sound like snake oil but fricking thing did something, I just hope it didn't affect the Catalyzer and oxygen sensors, on the way Back I filled up the tank with EXXON SUPREME .... So today is about 2,000 miles since I did that an it still running very smooth....
That is way too much Mystery Oil to be putting in a brand new car these modern cars don't take that much follow the instructions on the back 4 oz in the gas tank and like 8 oz in oil don't have to do that don't ever put a whole gallon in there you will destroy your car unless you're trying to flush it out and you're going to drain it out within the same day
Bottle says, "replace up to 20% of oil with MMO..." meaning a 5 quart system should only use UP TO a full quart of MMO. Some people just don't know how to read instructions 😂
Evidence of how it will destroy an engine?
In older carbureted engines, using mmo in gas at recommended mix ratio did clean carbon off valves, and upper cylinder walls, piston rings. It also lubricated upper cylinder rings and walls. Today it lubricates and cleans the same upper cylinder rings and cylinder walls through the injectors and cleans the fuel injectors. I would only use ratio advised. Not a whole gallon to a tank. Mmo is decades old.
so he put a gallon of mmo into a tankfull of gas..the car gas tank is 10 gallons?
@@fidelcatsro6948he put a gallon of mmo in one tank full in his mustang. 4 oz per 10 gallons is recommended ratio.
The Mustang is also a direct injected car. So no intake valve cleaning.
This is strange. What was wrong with the car to want to put that much oil in the tank? Sounds like he is trying to fax something that isn't broke. I can see why there is carbon build up. Plugs aren't designed to burn oil. Crazy.
If you live in the two-stroke world. Marvel Mysterio will almost burned by itself it's pretty great stuff
Hmm once I put too much in and had a couple of hard starts, I wonder if it was depositing on the spark plugs
No friction is what I was told.. too much slippage
@@latoshastanfield5523 Wouldn't that help startups?
I’m glad you did this test. I use Marvel for everything gas and diesel.
Even though the video is primarily meant to be entertaining, I really did pour a full gallon of MMO in the gas. I was a bit curious myself though I did risk damaging the car. To my surprise, it did not effect the car in any negative way that's perceivable. So many people believe that it has caused damage to my car which is interesting to me because it shows how people hold on to old or wrong information. Not that I'm saying it can't, or won't damage anything, it's just not guaranteed by simply overusing it at least once. Yay science! 😅
@@KarzKreated I’m actually surprised it didn’t foul plugs. Or at least have a mis fire. 😁
i put marvel mystery oil in engine and feul tank.. my engine light went away! It is the Chuck Norris or additives
My thought, gas used to be made from oil, now it has 10- 15 percent alcohol in it. Adding back some oil seems smart.
You’re injectors will be spotless 😂😂👍👍
It's a colon flush for the fuel system
It probably was a tad faster only because Marvel Mystery oil is harder to burn then gasoline so it was basically an octane booster it reduced the chance of detonation which your car has knock sensors especially being turbocharged and your computer probably added more timing and more boost. But I appreciate you doing this because I've added a half quart to my daily driver before and wondered how much was too much I guess I'm definitely good LOL
Hey Track pack GT, I may have happened to made a dumdum yesterday....literally probably the first time in my life I didn't read the instructions over and over of something I'm putting in my car..I'm usually crazy careful about anything I add but yesterday my dumbass just assumed marvel mystery oil was like every other fuel additive and takes the whole bottle. Anyway I added 16 oz of it to my tank in my Charger when I filled up the tank with right under 18 gallons of gas. After everything I've been reading online I'm super nervous it's gonna damage something. Wanted to ask you what happened with yours after adding a whole bottle by accident. Did you have any problems or did it run like it always did? Hope you get this and send a response lol
@@davidhuffman8543 I've put a half quart in 20 gallons of fuel the truck didn't even notice it nothing happened a quart to a whole tank no big deal it'll be fine bro just drive it Marvel mystery oil burns it's just harder to burn than gasoline you'll just have a really clean fuel system and injectors and cylinder LOL but it won't hurt anything. If you're really worried about it after a couple days top off your fuel tank again to dilute it more but I'm sure it'll be all right
@@trackpackgt877 that definitely makes me feel a heck of a lot better lol I've only used probably less than 2 gallons of gas since it happened and it does feel like it doesn't have as much power as usual but it's nothing major, but it is definitely putting out some smoke out my tailpipes. It's not a crazy amount but it's definitely noticable. I appreciate you responding to me... can't tell ya how much I been stressing over it lol was debating real hard about pulling my back seat out and opening up one of my fuel pumps to start pumping that fuel out lol
@@davidhuffman8543 I'm not surprised it's smoking with that much in it you're basically running two-stroke fuel right now so smoking is normal it's just burning it off I would just run it for a few days and put some fresh in it thin it down.
@@davidhuffman8543 it's a dodge, anything can happen.
Would you use fuel cleaner before or after an oil change???
It's said to be better if you do it before an oil change. The reason why is because the cleaner will dissolve carbon build up and that will make it's way into the oil. Using a cleaner after a fresh Oil change will likely cause the oil to darken much quicker. Not to say it would ruin the oil, but it's better to do it before an oil change for that reason.
I swear by Marvel mystery oil! Used in my Cleveland and now in my MDX
You won't really notice any improvement on a nearly new low mileage vehicle.
Its really for use on a high mileage or poorly maintained vehicle to clean, restore power
and smoothness.
We didn’t see it all go in, only the beginning and the end. What did you do with the rest?
Does the exhaust now smell like Dr pepper?
Be advised, newer vehicles with O2 sensors and cat converters may not do well with oil of any kind in the fuel system. Saying that I use MMO in every engine I own.
Cars, trucks, generator, snow blower, lawn mower.
It keeps seals soft and sealed. It fixes moderate blow by problems. It can even restore old motors compression issues.
50 years it's never let me down.
You’re supposed to add 4oz for every 10 gallons of fuel. Not 2
I don’t know. Video cut at 1:47 doesn’t show the whole gallon going into the tank. I’m skeptical.
Hi Skeptical! I'm Kirk 👋🙂
You not going to see the results now you'll see it after about driving 300 miles you'll see slight Improvement in fuel economy as well as performance
I think the idea is that you thin out the oil and it works better that's why some of the cars went from 10 w 40 to 5W-40 and then now it's 0w-40 or 0w 20
my bike runs faster on 5w40 compared to 10w40 but it heats up quicker especially idling on the lighter oil
Engine tolerances are getting tighter so the oil is getting thinner.
Wouldn't be an issue in a diesel.
this stuff REALLY is a Marvel!
We don't use the MMO oil because it's kind of more expensive that's why it's kind of a cost-effective deal
You can put a meter in your windshield or something and it'll measure the g-forces when you accelerate and maybe that way you can tell the difference if it really gives you some extra horsepower or not you can like do it like on a quarter mile or something
Berryman B 12 is the best I've ever used for fuel economy because it has acetone in it. With Berryman B12 fuel injector cleaner you have to follow the directions 100% though or you could do damage to your vehicle.
@king dz yeah, but DO NOT do that often.
@ williamperri3437-- I have heard good things about Berryman B-12 Chemtool, but it seems that it is very strong and harsh. Even though I use MMO on a regular basis, I bought several cans of Berrymans from Walmart. My 2002 Chevy truck has a 30 gallon gas tank, that has 165k miles on it. Since it has a 30 gallon gas tank, I added two cans of Berrymans at my last fill up. It's too soon to tell what benefits it will do, but I was wondering how often you use it.
Since Berrymans seems so strong, I was thinking I might use it once or twice a year, or about every 5,000 miles.
I put Berrymans in my 3.4 liter V-6 Impala every 2nd tank of fuel for a year. Follow directions on can though. At 75,000 mi. had sparkplugs, spark plug cables replaced. Engine is quiet.
It amazes me how many people in this country can't read how did we ever get to be a strong country
Fuel stabilizer like MMO and Stable I thing it’s spelt STAY BL, that stuff is literally not only good for the engine, but it’s like nos. I put it in my bike and my truck, made both more responsive and sound smoother. But too much can and will clog by foaming up
Dump in a gallon of Lucas fuel stabilizer
th-cam.com/video/CmvzfZx8pwU/w-d-xo.html 😉
Consistently using MMO in my engine oil and fuel along with lucas in the fuel sometimes too has removed the symptom of pinging from my trucks engine.
Your warranty service watching this video.
👁👄👁
😂
I did this to my car and the mechanic said my engine survived
Does it make your oil dirty faster?
I bet those intake valves are spotless
Only one side 😁
Direct Injected. No fuel on the back side of the valves..
Too much MMO and you have upstream and downstream O2 sensors, full rev will set the money light to blinking until it clears out.
MMO may be good for your engine but using too much could damage your cadylitic converter.
best when used before a long trip. IT DOES WORK! around town it may foul your plugs. Its LINSEED oil which is an incredible astringent =CLAEANER. but it has to get HOT TO WORK! Dont use in winter months. just mho
Friend of mine who takes like 5 Tylenols at a time has the same reasoning. If two is good then 5 is better.
Tell your friend to do some research, too much acetaminophen will do serious damage to your liver.
We never actually see a full gallon poured in 1:40 I feel that cut was deceptive. Funny video though, I wonder how many people tried this after lol
Cats clogged to hell🤣
Now your car will not pass a smog test. Will need to replace your 02 sensors and the cat.
It could be good like a cleaning the fuel injectors and cleaning the carbon in there around the piston rings it could actually work but I wouldn't imagine it would add that much
I’ve been using Marine outboard two cycle TCW3 rated oil at 1oz per five gallons of gasoline for years works great
Buy a quart give it a try in a few full tanks. Marine outboard two cycle TCW3 rated oil in your car. You won’t know the car is running at idle. You can use Walmart or any other marine outboard TCW3rated oil. It burns ashless so no harm to sensors or converters. Works like MMO or Lucas fuel conditioner but cheaper and better. This is why two cycle engines last so long.
I think the gas companies are supposed to be put in that kind of additive in their gas something and they don't add any more than they think well actually work otherwise the gas companies would put that in there and sell it to the public the engineers and researching design probably test it all that stuff out before but they never really tell us because it's a trade secret so they can have something better than their competition
Try TCW3 at one ounce per 5 gallons of gas. Works great!
A V6 with a fartcan???
MMO doesn’t take in effect right away… it takes time. And you actually gotta use it use every fill up and every oil change…
No, the directions state put 4 ounces in per tank full.
Anytime you add oil to fuel, it will leave carbon deposits on the pistons. After that tankfull, put a borescope down a sparkplug hole. Carbon raises compression and requirment for octane. More is not better.
MMO isn't oil.
It does a help a lot, you just have 1 gallon less to fill up. 😂 thank you
I recommend the synthetic blend instead of that regular brand for the synthetic blended motor oil in your 2020 mustang car.
It's can't be true 🤔 it would definitely change the chemistry of whole tank. Spark plugs should be oily. Car might gonna run Lean or Rich(probably leaner and hotter). If it's really true it was probably running so lean and hotter and oily substance burned tight off from the sparkplugs. I over treated once with seafoam+mmo but that was not even close to 1 gallon lol and I found my sparkplugs were oily after 350 miles. I don't know man but oily substance definitely not good for catalytic converte.
What do you mean nothing happened? Fouled the plugs didn’t it? The car running a bit better was in your head.
1:39 lol you said that wrong you can have too much of a good thing. I just hope this goes well. 😂💯
I don’t think he put the whole gallon he cut the video when he started to pour and restarted recording when the bottle was empty 😂
I put a quart in think in New Jersey the gas at the pump 87 regular at a gas station was bad..have to wait and see probably fuel injectors aren't going to need professional cleaning I'll wait a tank too with this stuff
It’s really not that useful unless you’re dealing with an old engine that wasn’t taken care of
Dude that's WAYYYY TOO MUCH !!! I added over 3 bottles of Lucas injector cleaner to my cargo van thinking that more is better but it messed van up and I had to change all my oxygen sensors plus go through 2 tanks of gas before van drove normal
As Bugs bunny would say " What a Maroon" what about the exhaust system, cat converters , O2 sensors , do not use this MMO in a modern ICB automobile, every engine air/fuel mixture is computer controlled. MMO is a good penetrating oil for cleaning/freeing rusted parts.
Wow, ...boldly went where no one has gone before- a whole gallon of MMO!
Actually they say: “too much of anything, even a good thing is bad for you .” - Captain James T. Kirk
And if Kirk said it you can take that sh*t to the bank, because it is gold.
It’s mostly because even óptimo it doesn’t ignite. If it did then it would be fine
Don't put in gas tank not good for catalac converter and oxygen sensors
Marvel Mystery oil was used for sticky lifters in engines and help shifting in transmissions and it has a kerosine base not fuel systems
Lol your crazy bro! But you gave me confidence in buying a jug of it though thanks.
Modern cars have catalytic converters; which are damaged by oil. Use MMO in engines that do not have a catalytic converter. OK to use in oil though.
Wow that’s nuts dude. I would think it would run too rich lol. Maybe it did some cleaning
Ya when i run to much it trips my check engine light and shows code for too rich i think it is
Did you do this just once or do you do this regularly now?
Just once for this video. The video is for entertainment only and it's not recommended to use more than directed. 🙂
Probably best to do it with an old car. A new car won’t change much
Thats is a New well taken carece car. The difference Will be better using an old car.
The scent is actual peppermint oil.
It smells to great on top of that
