[@mytmousemalibu]

I think the big thing to takeaway from this is the carbon in the combustion area is much harder and crystalline than any of the carbon in the induction tract. It is formed into a much harder deposit in microscopic amounts over time under great heat and pressure and microscopic-level impact. The carbon in the induction is much softer and still oily and is much more easily dissolved by a solvent like this. Same for the crankcase deposits and reasons it works well there like flushing sludge from lifters and allowing the hydraulic elements to restore working properties. I would be curious of how well it cleans up the piston rings and ring lands. There are really only a few ways of really decarbonizing the combustion areas. 1. Mechanical removal, i.e. scraping it off, bead blasting, etc. 2. Strong specialized solvents/acids. An example would be like the concentrated solution used in commercial injection/induction cleaning machines. 3. The easiest and most accessible method is steam scouring. Yup, plain old water. If you've ever seen an engine that had a head gasket go bad or a head crack and allowed coolant into the engine and it being run this way at least for a little bit, the effected cylinder(s) are often much cleaner than ones that didn't intake any water/coolant. Engines with water/methanol injection also exhibit cleaner cylinders. The water flashing off to steam creates a powerful cleaning action, in piticular at higher engine speeds/load.Most of the Seafoam in the cylinder is partially burning and flashing to smoke. I feel it doesn't have enough time nor the best properties to work on hard carbon. I have a Duramax with water/methanol and it stays pretty clean for a diesel. I have borescope'd it. I have seen cars that water had cleaned a cylinder so spotlessly clean it looked brand new/unfired but adjacent cylinders were dark and crusty. It has had diesel leak into the crankcase also which diesel being a great solvent, worked much like Seafoam in that application, the engine is 100% spotless clean internally and it has 165,000 miles on it. A lot of heavier distillate solvents like diesel, kerosene, mineral spirits/stoddard solvents would work like this. I suspect stuff like Gunk Engine Flush is mostly mineral spirits and Seafoam is certainly go some in it. ATF Dex/Merc is another great fluid since it has some great properties/high detergents. Like pouring in cylinders for stuck rings, etc. My background is all mechanical & from a young age, working on cars at our family owned car dealership from about 5yrs old on up, always worked automotive jobs, Wyotech graduate, worked professionally on BMW's, Factory trained BMW S.T.E.P. grad. BMW Master tech 10+yrs and now Aviation mechanic, A&P License, worked both piston and mostly turbine powered, just cooperate jets now. So my mechanical knowledge and experience runs pretty deep, all my life in fact! No spring chicken here! If you can finely meter water to that mower under full power and under load, I think you will find a much cleaner cylinder. For the soft carbon, Seafoam will do just fine as will other like solvents in the right proportions. Great video, keep up the great content! New sub!

[@josephd8814]

True the water does have a great steam cleaning effect, but i still wouldn't trust it in my crankcase. I believe your better off taking the engine apart and then steam cleaning the internal parts drying it of course and then put it back together. You have to remember water does not have the capabilities of oil in the fact that you can score the cylinders. So I would be very careful in how long the engine is running with water in it.

[@mdingle11]

Joseph DiTomaso no one said to put water in the crank case. You spray water into the intake to clean carbon from the compression chambers. Putting water in your crank case will do nothing but kill the motor.

[@gbudning]

Since most of the seafoam is burning when it's ingested via the intake tract (hence impairing it's effectiveness), do you think a piston soak lead to more noticeably effective decarbonization? I understand that it wouldn't be nearly as effective as water injection, but just for those of us are reticent to try it

I pulled the heads off my !international 304 V8 as part of a re-seal of the engine. Man those pistons were dirty. I previously ran Seafoam in the oil, gas, and through the vacuum. The Seafroam treatment made a huge difference in how loudly the engine ran. The thing quieted back down like a new one. To get the carbon off the pistons I ended up using parts cleaner. All the other stuff I tried, WD40, Seafoam has their version, and who knows what else just didn't seem to cut the carbon. Watching your videos on cleaning pistions and valves, gave me the confidence to get right on it. I did not use a metal wire brush though. I used fiber roloc. Thanks for the videos.

[@ProjectFarm]

You are welcome!

[@rcwagon]

I agree with other commenters - you put tremendous effort into your videos. Thank you. On the piston, you can see the Seafoam cleaned it up some especially if you look at the letters on the piston head. On the cylinder head, it is harder to tell but it is cleaner based on the spark plug.

[@ProjectFarm]

You are welcome!

[@ericm834]

It's not all about how clean it looks. If the valves seal better that's the biggest improvement. The trifector of in the fuel, oil and sprayed in should give the best results. Freeing up the moving parts from sticking and sludge buildup. Which most engines do not need at all. Just run good oil, stabilize the gas. Changing the oil before storage can help with preventing leaks form the acidity of used oil. Also gives less time for sludge to settle or cake onto moving parts or in areas you don't want it.

[@ProjectFarm]

Eric M, I think you identified the reason why the intake cleaner improves results that can't be seen--it allows the valves to seal better! Thanks for watching the video and commenting!

[@keantoken6433]

As much as I like to see clean pistons, this seems to be true. Even if the cleaner doesn't remove all of the carbon, it's possible the improved combustion will clean it up in a month or so. I would only add that as the engine is running, the carbon coating the inside of the chamber constantly flecks off and this is a source of potential pre-ignition or pinging. So if you have an engine that is vulnerable to pinging (how common is that anymore?), having the whole head cleaner could be a good thing.

[@seanbailey317]

In higher mileage cars it can actually Decrease the seal on the valves as the coke takes up the small gaps and fills them. cleaning this out can make the car run roughly.

[@keantoken6433]

I've heard TCW3 2-stroke oil in the gas will seal worn piston rings pretty well and reduce oil burning.

[@ericm834]

Sean, if it reduces the valve seal then the valve seat is damaged. Those would likely fill up with carbon again as the soot would gradually seat back into those areas. On a different note: I recently gave a honda EU1000 generator that I go for free a sea foam treatment. It had a smoky haze you could see out of the exhaust and the surrounding area was hazy. Started with the oil flush. Put some into the fuel. Ran for a few hours. Put some into the combustion chamber . Put the plug back in and lightly turned it over to get everything coated. Left for a few hours, pulled the plug and lightly cycled it to remove the excess. Put the plug back in. Sprayed into the intake while running, about 1/2 a can. Then ran for a few more hours. Did a oil change and spark plug change. Fires up good and the smokey haze it used to give off isn't noticeable unless you got it set into a corner. It was a if it cleans up great. If I ruined it then I'd turn it into a project to rebuild with the kids in a few years.

[@Big88Country]

Another true to life video, thank you! Not much change after one treatment but if you ran the seafoam all season I am sure there would be a dramatic difference in the carbon buildup. Thanks again Project Farm!!

[@ProjectFarm]

Thanks and you are welcome!

[@MyManEarl]

While it's hard in real-time watching the video to see a difference, when I screen-captured the valves' before-and-after shots, there is a marked decrease of chunky carbon buildup. The "color change" of both valves is minimal, but the accumulated solids seem significantly reduced. I've been skeptical of any additives, but after seeing your triple-test of Seafoam, I decided to give it a try and notice less throttle sticking and overall hesitation on a 100,000-mile motor. That said, like you, I don't trust my "feel" given the Hawthorne effect. However, the onboard computer shows my average mileage at 21.5 versus 16.9 before the treatment. The throttle sticks less, and I heard and observed that during the ingestion of Seafoam. So, I'm a believer, but seeing the marginal results here does give me some pause.

[@ProjectFarm]

Thanks for the feedback.

[@MrMegatony73]

I ran Seafoam through the vacuum line in my 2001 Lincoln Navigator with 189k on it after watching your first video in this series on the truck with high miles. I was BLOWN AWAY by the difference. It immediately ran smoother and quieter. According to my onboard computer my gas mileage has gone up from 10.5 mpg to 12.5 mpg (local driving, lots of hills). Best $10 I ever spent at an auto-parts store. I am VERY impressed. I think I will run it through the motor on my wife's Chrysler minivan (100K) and see if that makes a difference (I am guessing it will)!!

I used this product as a “fuel mixture carburetor cleaner” for an old dirt bike. I added several ounces to the fuel tank and repeated twice. It made a huge difference in the carburetor performance both at idle and at operating speeds. I recommend cleaning and re-gapping or replacing the spark plug after a deep cleaning such as this one.

[@ProjectFarm]

Thanks for the feedback.

[@RogueBlackheart]

This is kinda long, but its generated from over 50 years of experience with internal combustion engines, including flathead, overhead valve, water-cooled and air-cooled two stroke, turbine and jet engines. Gonna leave out a bunch of background and skip to modern day engines, fuel packages etc. In the 80's oil companies and fuel blenders began mixing in "cleaning agents" and also ethanol alcohol to increase the volume of fuel sold. That is, increase the fuel prices without increasing the amount of fuel sold. Yes it helped clean our engines, somewhat, but also introduced us to intake valve deposits, plugged catalytic converters on non marine engines, vapor locking and a myriad of other heartaches. I was fortunate enough to have been included with factory research and development and experimentation with Mercury Marine(Mercury outboard motors and Mercruiser Stern Drives) and OMC(Johnson/Evinrude outboard motors and OMC Stern Drives). We found the primary cause of all these problems to be the additive packages from the fuel blenders and reckless use of ethanol added to motor fuels. To make a short story long, OMC and Mercury Marine developed some additives to try to help combat some of the the horror stories created by irresponsible oil companies and fuel blenders. Similar to Sea Foam(but I believe to be superior) are OMC's Engine Tuner, primarily for 2 stroke outboards, but will also work on 4 cycle marine and passenger car engines, and Mercury's product(cant remember the name)which is similar in chemical content because it produces similar results. The carbon-choking problem was so severe in water cooled outboards that it literally glued the piston rings into the ring grooves in the pistons to the point of producing 0psi compression. OMC Engine Tuner used heavily over a period of several days, literally brought these engines back from the edge of needing an engine overhaul back to factory recommended compression pressure. There is alot more to this story, but I suspect I have lost many peoples interest already LOL. If you are interested in more details, contact me at [e-mail]. Thanks for your time and patience Rogue

Seven years old, and this series is still golden. Maybe I have a much better screen than some, but I can clearly see a substantial reduction in the carbon.

Excellent video. I'm surprised it didn't do a little more. As with most tests like this I have seen, it took up some around the edges and seemed to remove some of the surface, but didn't make a huge dramatic difference. I know allowing it to really soak in cylinders first and then running it does more, but it's such a pain to do, especially on anything but an inline engine. Great job!

make sure engine is off and cool to touch. I used baking soda and vinegar (carbon deposits got easier to clean). make sure you rotate the flywheel to close the I/E valves before hitting those areas. rotate flywheel to bring the piston away fromTDC to wipe cylinder sleeve clean (do not use baking soda vinegar in cylinder sleeve area). i used old sparkplugs to leave into the valve cover for cleaning with baking soda vinegar solution. wipe just a little bit of WD40 on the piston tops/combustion chamber areas to prevent rust. do not use WD40 on cylinder walls. use vaseline on cylinder walls or cylinder wall lube(summit racing might sell it, dry film powder lube). repeat other side if you have another piston there.

Hello, interesting your videos I am a technician in diesel engines and generators .ASE plus other 24 certifications, Native of South America (Uruguay). I knew the engine cleaning system inside with water by my uncle he showed it to me by dropping it drops in the carb ... mmmmh year 1970's, old school. I can also tell you that he had an old Packard from the year 30 (Limousine) who needed a gas station to be able to ride in it, especially in South America where the Gasoline costs fortunes. He did not give up and invented a system that used water vapor in the intake of the carburetor. I remember that we went out to do the test with a liter of gasoline and he gave us 12 kilometers and when he put the steam system we made with a liter 19 km. I have the plans of his invention.

Seafoam totally cured a blocked the idle jet on my 17 hp Kawasaki v-twin (from setting unused with gasoline too long). Process took several months of running a very heavy concentration then letting engine set a couple weeks then running again until hot, then setting. Repeated this about a half dozen times. Toward the end, each time engine would idle better without using partial choke to keep it idling. It idles perfectly again now, never touched idle mixture adjustment with a screwdriver either. I've used the product for many years but never had this kind of success before. Of course Seafoam won't fix a jet blocked with a piece of dirt that can't be dissolved chemically..

[@JasonBeeneistheLordGod]

I like the engine your doing these experiments with, I have one similar that was given to me, the oil was grey & chalky I ran some clean oil through it, cleaned the carb & put a new plug in it, I have been using it ever since with no problems, the engine is simple, but perfectly engineered in my opinion.

I swore by Seafoam for years until me and a friend did a little test of our own. He was a Berryman B12 Chem guy and we had our debates and put them to the test. We filled 2 glass jars, one with Seafoam the other with Berryman's B12. We placed 2 completely carbon coated valves from the same engine, one in each of the jars and let them soak for 24 hours. The next day was the moment of truth... The Seafoam valves, while some of the carbon in spots had come off, 80% of the valve was still coated and needed firm scrapping with a paint scrapper to remove the rest of the carbon. Berryman's B12... 50% of the carbon was gone when removed from the jar, the rest and I mean ALL the rest either fell off coming out of the jar or could be rubbed off using only your finger... Needless to say, I use Berryman's B12 now.

[@TruthOverLies]

The true test is burning it through the engine. Soaking in a jar is not a true test.

[@flyonbyya]

The question is did the treatment measurably impact any performance metric, be that power, economy or long term durability.

[@coletonanthony9588]

If there are any I feel like it'd be similar to a transmission oil change. Its not that doing the maintenance created a problem, rather that it exposed existing ones. I imagine he would have told us if there were any problems he noticed after doing the treatment.

[@loganklein366]

I think the difference around the valves was pretty significant. That carbon, if the buildup gets severe enough, can cause the valves to seal improperly, which can cause some headache down the road of an engine's life. On the surface of the piston and on the cylinder head, I could see a difference but it wasn't super significant. I think though using SeaFoam can prevent improper valve sealing due to carbon buildup, which isn't a problem that is going to come about too often, even on a tired, old engine.

I appreciate the dedication to experimentation and objective results in this series of videos. I am a believer after treating my 99 rav4 with Seafoam, and I appreciate the visual. It seems like the hard carbon is still in my engine, but it runs noticeably better and I'm satisfied with the treatment. How long do you leave Seafoam in your crankcase? I left the Seafoam in my crank case for two days, and yes the drained oil was black.

Seafoam worked great on my weed eater. Previously, it would only run with the choke on. Once it got hot enough, it would cut off. Then, I added Seafoam to the gas, it almost immediately started running like normal again. I know this is somewhat off-topic, but the product does work for many applications.

[@reidjohnson6803]

Kinda curious why you didn't use the Sea Foam as directed on the can. It is hard to judge how well a product works when not used as per the manufacturers recommendation. My experience with sea foam has been all good. Though I'd never use it, or any additive in a new engine (I'm referring strictly to cars in this comment), I have found it to work excellent in pre oil change applications to help dissolve sludge. Being a petroleum based solvent, it is very effective at breaking down the gas and oil based sludge that builds up in higher mileage engines. Unlike other "motor flush" products that tend to break larger pieces of sludge free from the engine, only to get caught up in the oil pump filter screen later, Sea Foam dissolves the sludge and blends it with the existing motor oil to be emptied out completely when draining the oil. For oil change cleaning, I use 2 ounces to each quart of motor oil. Start and IDLE the engine only for about 5 minutes, or until at operating temp. Then drain oil and proceed as normal with the oil change. I add 1 ounce per quart of oil when refilling the oil. I also use 1 1/2 ounces per gallon of gas every other fill up. I've had it twice in the past solve engine knocks on high mileage engines. Once in the top end, and once in the bottom end. Gave me a bunch more reliable driving miles, as I have yet to replace the main bearings (4.0 L ford v-6), and still driving it for 30,000 miles since I added it to the vehicle. The engine has 300,000 + miles, and was rebuilt over 200,000 miles ago. Never thought I'd see that many miles on a domestic pick up truck.

[@johnnyreb86]

I put sea foam in the oil of a 1996 Saturn I have with 180k miles that had very sludgy oil and it cleaned it so well that I developed a couple oil leaks and it started sucking oil through the valve guide seals! I replaced the seals and now it runs great. I would only use it on a car that isn't so old if I used it again, it's a strong solvent.

[@josephd8814]

I agree Marvel Mystery oil is good but the seafoam did a better job you see it in the results of the compression readings.But of course the best way is to tear down the engine and clean all traces of carbon but of course that requires time and money. If its just an old daily driver then use seafoam or marvel mystery oil. But if its an old classic then tear down the engine that's how I look at it!

[@rickeyviger5271]

Same issue here,cleaned the engine so well it started leaking and burning much more oil than it had before :/

[@burnychaplin4601]

Coaster we used trans fluid back in the70s hold the engine at about half throttle use a old oil can the smoke and shit would pour out of the exhaust did many 10 dollar tune ups take a rough running car smooth the idle out and get rid of the pinging and rattling in a minute

[@CoastRC]

Burny Caplin what a great idea i will have to try that, Thank you!

[@jason127x99]

Burny Chaplin ever add it to the engine oil? I've been told to add a 1quart of ATF and 4 quarts of oil in a 5 quart oil change. I don't see why you couldn't do both.

[@KC9UDX]

jason127x99 The reason guys put ATF in their oil is to clean out the oil passages, especially in hydraulic lifters. I don't know that it is effective at all for this. What does work is draining all the oil, filing the crankcase with diesel fuel, running the motor for a few minutes, draining the diesel and putting proper oil back in. And yes it's safe.

[@andrewbartleman9169]

KC9UDX I'm not sure that is safe because diesel today is very dry and doesn't have much lubrication qualities anymore. Ever since they stopped sulphur from being added to diesel (very good lubricant for diesel injector pumps and injectors) the diesel isn't the best on older injector pumps. People have had extreme wear on their pumps within 100 000K when the pumps were rated for half a million K. You can combat this by adding 20% bio fuel for lubricant or 2 stroke oil for my old mechanical pump because I don't want to shell out 3500 for a new pump or 1000 for a rebuilt one just because we have to use dry ULSD ultra low sulphur diesel . So no don't use run your engine crankcase on diesel you will damage your engine. Ever hear of cylinder wash from too much diesel injected ? The injectors actually wash the oil off the cylinders causes excessive wear and this diesel goes past the rings into the sump and dilutes the oil. When you have diluted oil in your oil analysis you also have high amounts iron and aluminum found in the analysis which shows accelerated wear from the diesel in your oil.

[@nemoskull2262]

now you just need to use this ONE WEIRD TRICK to make seafoam work for you!

[@TonicofSonic]

It can be sprayed anywhere south of your mass air flow sensor on your intake or sucked into the brake booster line, or added to your oil, and added to the gas. Any of these will get it into the chamber except the oil method, which cleans the rest of the engine.

[@09ThunderOne]

Can you do a comparison between top tier gas and regular gas to see if it makes any difference in reducing buildup?

[@TexasBulldog74]

People saying. " not a big deal". Run a can in you're daily driver every 3-5 tanks for a while and it really cleans the injectors as well as the pistons, valves and combustion chamber. It's a great quality product that will help keep your care running great.

It may take multiple treatments on an automobile, but considering it costs a lot of money to tear down a car this is a very cheap alternative to get back performance from your aged vehicle.

Okay, I'm not sure if anybody else is ever left this comment or not but I'm just going to. I don't have a ton of experience with seafoam but with my experience and cars and what not anything that's going to work is going to take a little time. Somehow soaking. I swear I've you see them and it's worked but maybe not you should try saturating the parts and then letting them blow through the motor. Although sometimes isn't it just easier to take a metal wheel and fix your motor than put all these products there? In any case.

[@tonywdidit8826]

I dont believe there is any single use magic product but eliminates all the carbon, but is am using a bottle of Seafoam in my oil at oil change, and a can in my gas when I get the oil change. I used to get about 21mpg in the city in my 2.5 Altima, now I get right at 23-25 depending on where I purchase fuel. I wont buy fuel at Kroger or Marathon. My worst gas mileage came from those two stores. I will go out of my way to find a Walmart or Sunoco. They seem to have the best fuel for the price. If I am driving on the interstate I will pay extra for the Shell fuel, rather than take my chances at side road independents or truck stops. Walmart has huge buying power and demands good gas from the fuel farms. Thanks again for your dedication to information!

[@kennethhoulton9358]

Thank you very much for the video. I have watched all 3 done thus far. It is sad the number of comments which are based on their opinion walking in. I do agree that in this case, it does not appear to have made a noticeable difference visually. Also don't know if it ran smoother after. For all the pre-conceived "snake oil" believers, I have two things to say: 1) Watch videos #1 and #2 with his pickup truck. Tell me that there was no noticeable change in how smooth the engine ran, the top-end noise, etc. How much water or diesel or ATF are you going to put in the gas tank per gallon? How much water are you going to add to the oil? How much diesel or ATF are you going to spray into the intake? 2) A number of you sound like long term mechanics etc. "Just tear the engine down and scrape it". On the other hand, an individual who has less experience but can do some mechanical things is much better served by SeaFoam or similar products because they clearly tell him/her how much and where to put the product for desired results. And, Yes I have used SeaFoam in cars in the past. It definitely made a difference, though other products may also.

[@ProjectFarm]

Thank you! Great point regarding the great value in using Seafoam instead of paying a mechanic to perform avoidable repairs.

[@catgolfer1]

I really liked watching your videos. I did the same thing to my engine, only with Marvel's Mystery Oil. It is a 1989 Chevrolet P30 motorhome chassis with a 7.4L 454 engine. It had, at the time, 86k. It had a terrible tick off the line and just didn't run very well. I kept with the Marvel's regimen in the tank and the crankcase and wow, what a difference. My Onan generator in the motorhome even runs better!

[@ProjectFarm]

Thanks for commenting on this.

[@bill154cub]

I also tested seafoam in my generator that had a gummed up carb. I added seafoam to the gas tank and ran it then let it sit. After a while I fired it up and she ran perfect. Seafoam is also a fuel stabilizer too.

[@Ratkill9000]

Been using Seafoam for the better part of 20 years and it's worked great. Of course we run some every tank of gas in our lawn mower, so we get a longer term of cleaning vs a couple hours. Though we mostly use it for the stabilizer aspect, the benefits are there. I'd suspect after a couple months of using Seafoam with every tank of Ethanol free (Non-oxygenated) gas, it would end up being cleaner.

[@ProjectFarm]

Great strategy using it in every tank to prevent the buildup. Thanks for watching the video and commenting.

[@Buck1954]

When I use Sea Foam, I pour it into my gas tank, not pour it into the carb in big gulps. This reminds me of dumping automatic trans fluid in the carb back 40 years ago. I suggest you pour into your tank, run the mower until dry and then test. Run a couple of tanks the same way. I use Yamaha Engine Med in my motorcycle and it definitely cleaned out the engine which was being clogged by ethanol. I think water is a hassle.

Hey there farmer, I have been watching a few of your videos and I have not up till now heard you mention this product, I have found over the years as a professional auto and RV technician a product that works really well for decarbonizing cylinder heads and on Motors that have carbon buildup on the Pistons it works very well there also, it's a product that is produced by Chevron, it is called Techron, just in case you haven't heard of it, they have a fuel injection cleaner and a fuel system cleaner as well, and I normally use the fuel system cleaner in all of my vehicles every time I change the oil, I'll generally put a 20 oz. bottle of Techron cleaner into either of my 6 vehicles, and with that I am able to keep my systems clean all the time, and it's making my vehicles get the best fuel mileage possible that way... P.S. Oh yeah, great job on the videos, they are quite informative and I like seeing that you put those motors through hell, haha, keep up the good work....✌😎👍

After watching all 3 videos, my personal conclusion is that it's not much good against hard deposits, but works great on surface deposits that are easier to clean. The difference it made, at least in the truck's oil, appears to have been spectacular. Probably the fuel system, too.

[@ProjectFarm]

Thanks for commenting.

[@YodaWhat]

+Project Farm, you should stick a basketball inflator needle into the carburetor end of your hose, so that the Seafoam (or methanol, lacquer thinner, isopropyl alcohol, WD40, etc) comes out slowly into the air stream. Water, ATF, brake fluid, etc., I would use sparingly if at all, since they are not meant to burn. Chlorinated solvents should not be burned at all, since combusting them will produce hydrochloric acid and phosgene, both highly toxic. Also, I would recommend running the engine much faster during the treatment.

[@bagelbytes69420]

You can get as good or better results by simply sucking up a bit of water through a hose in the same manner as the seafoam. Everyone thinks this will hydrolock the engine but it wont as long as youre careful like with the seafoam. It basically steam-cleans the valves and piston in the same manner, and its free!

[@63turbo]

My favorite method for taking care of carbon deposits is Techron added to the gas. It does take a full tank, but it really does work! might be a fun one to try....

[@Ozarkprepper643]

Appreciate you taking the time the show is true results by pulling the head. It didn't miraculously make it look brand new, LOL but it was an improvement. Seems like it would be most useful as preventive maintenance on carbureted engines, preventing carbon build-up to begin with. I've always felt carbon was a large contributor to engine wear, as well as Air volume and velocity restrictions. Then as the carbon tends to absorb more fuel the problem magnifies itself.
