Plain and simple best stuff ive found. BEst price hands down . Outperforms all others ive tried. VAlue cant be beat. Never let me down . Never dissapoints. Personally used it in over 20 cars, many repeatedly , with no adverse affects /damage to the vehicle. Great stuff. No B.S. Money well spent! Glad its going strong and is available in more places than ever, still for a hell of a price. Thanks Berryman again!

Been using it for years . First heard about it at the drag races. VEry surprised , and even made skeptical , by the great price. Price has managed to stay low throughout the years. Have tried many other expensive,even professional, products. This one always seems to work. Stopped wasting money , and started saving it instead. Used it countless times on cars and trucks , new and old. Have even argued with auto parts employees over it, when they try to sell me seafoam or STP (on sale). Ive even had one say that its too strong and will cause my seals to dry /crack……. Nver happened . I used it for the whole lifetime of my Nissan,as a fuel addititve , and as a solvent to clean my injectors directly through the intake. always felt the diffrence immediately. Never ever felt like i wasted my money and got robbed (unlike others). Never had no engine trouble. Sold it at 280000 miles going strong. Repaired the valve cover seal , my friend (long time mechanic)thought i had a rebuilt engine because it was so clean inside. I have amazed and made many other believers of friends, by helping them tune up/maintain there car using berryman b-12. First they are skeptical, think its too good to be true, waste of money. Once they experience the difference in power. Smooth idle. Car even starts and feels and sounds different. Ive had some older cars feel renewed instantly. Now everyone is constantly wanting to use it on there cars, or asking me how to do it again. They all want to know so they can help other people/themselves with there car maintinance. First and only mandatory , and consistent product on my list for tune up supplies. Other items can be substituted , But for Berryman there is no close substitute. Thanks to Berryman for offering such a quality product and keeping it affordable. Helps many people , especially when times are tough to keep there vehcles running great!

You have to remember that he used these products straight from the bottle, they were not diluted with gas , so it would be less harsh on rubber that is used in the fuel system. When mixed with a tank of gas and follow the directions on either one , that's why there is a certain amount of product per gallon of gasoline.

I was always a seafoam fan, until i started using barrymans in small engines and the way that stuff cleans out the carbs mixing with gas, is simply amazing .

Berryman's is less than 1/2 the cost of Seafoam. I've been using it since the early 70's. My Dad used it on everything that had a motor in it back in the day. It even helps break down oil sludge in the oil system prior to changing the oil or doing a flush.

[@booradley1065]

I have used in the crankcase as well. They used to sayto do that on the can but removed it a while back.

@@carenthusiast6748 yes thank you

[@psdaengr911]

It's a good cleaner- if you can soak and assembeled system's parts with it - specifically like an pre-oil change engine flush, not for intake valve cleaning. If you have loose metal parts there are better, faster cleaning chemicals and methods.

[@psdaengr911]

@@carenthusiast6748 Yes, it would work, and the longer the soak up to 2-3 days, the better. Almost any fuel system cleaner will work. One problem is that all of them will react with polymer seals in the engine. This isn't a problem during the soak where the chemicals that get past the rings drip direct to the sump. It can be if the oil is not changed immediately after the engine is brought up to operating temperature. The speed of chemical reactions increases as temperature rises.

[@PapaSmurf337]

Chemtool is half the price normally, and it's been my go to for the last 20 years ... I'm only 36. And that recommendation was passed on to me from the much older professional and backyard mechanics that I had the privilege of learning from.

It took about 15 minutes with some sitting and reving and viola it runs like it did before I parked it. I am a believer!

[@bundysgarage]

The stuff works!

[@jefferyyoung5401]

I used B-12 fir the 1st time this week and within 20 miles my engine was responsive again and winding out to top rpm. I used it as a fuel additive which is a method I RARELY employ but now I swear by it. I have 2 more scooters with similar symptoms but I am confident the B-12 will handle the workload. I will be trying it in my ultrasonic cleaner in the near future.... Great Product!

[@electropentatonic]

My Yamaha 650 had been sitting for a few years and went to crank her up I couldn't get it to stay running, obviously. So I pulled apart both carbs and was greeted with a green gunk in every orifice, jet and crevice it could crawl into. So naturally I went to O'reilly's, my local auto shop, to pick up some Seafoam. When I asked the gentlemen behind the counter to lead me to the Seafoam he said, " hey, why don't you try this B12, its half the price and works great." Whatever, I got nothing to lose and its half price, so I grabbed 2. I soaked my jets, tank and filled the carbs up and let em sit for 2 days. That B12 cleaned the PISS out of that thing. Those jets didn't look that clean when I bought them new! Anyway, I'm a fan. Seafoam is great too but this worked just as good if not better for carb cleaning applications and its half the price. Bike started right up.

[@Peppermint1]

First off, thanks for wearing gloves. Too many people think the skin is safe enough when handling car fluids and chemicals. As for the Seafoam, I've used it with my engine oil, the engine has 130000 miles on it. After the Seafoam treatment and an oil change, I was shocked to see that the new engine oil stayed clear for well past 5000 miles. Before the treatment, the oil would turn dark within the first hundreds miles. So yes, it does clean the engine. As for the B-12, I'm not sure I would pour that inside the pistons or inside the carter, that stuff looks a little too strong for various engine seals and o-rings.

[@phiksit]

Yes, I think Berryman's has stronger solvents. In fact the can I just bought doesn't even match the msds sheet online. My can lists toluene, acetone, MEK and butoxyethanol which all attack rubber.

[@lzxray6781]

My Grandpa and my Dad used Berryman B 12 chemtool in the spray for cleaning carburetors and later in the fuel form. I've used it for years and it's the real deal on cleaning fuel injectors and filters and getting rid of water in the gas.

I put B-12 into my 2004 Tacoma's gas tank and it did well. I put B-12, about 3 oz, in my Honda Rebel's tank and my carburetor started leaking. B-12 will eat seals. My takeaway is if you drive a lot, a tank of gas a week, use the B-12. If you don't drive a lot, use the Sea Foam as that is what it was made for. B-12 is also cheaper. Both are good but be careful with the B-12.

[@victorrobison5069]

I am a mechanic with 35 years experience. Nothing in a can will make a mechanical repair. If you need a new seal, replace it, don't buy an additive with "Stop leak". That being said, these two products are great at achieving two different results. Seafoam will remove carbon when introduced through the intake system, and will help remove condensates from oil. Berryman as a fuel additive will move water and clean fuel system parts that contact liquid fuel, and remove fouling from plugs. Not really a substitute for a tune-up, but a quick way to pep up a rough running vehicle. The difference shown here is solvent compared to lubricant. Still interesting, thank you Bundy's Garage!

[@timsmoen]

My first experience with Berryman B-12 was in 1990 with a 1981 Buick Skylark 4 cylinder throttle body injection ( wife’s car ). She told it would not idle at stop and since it was an automatic she had to put it in neutral at stop signs and stop lights and keep her foot on the accelerator. So I got on my motorcycle and drove to the parts store and bought a can of B-12. I got home and removed the A.F. cover and filter and had my wife start the car. The old throttle body injection was a single injector nozzle sitting vertical over the throttle body spraying directly into it. It was half clogged and just spitting. I poured the entire can of B-12 into the tank which was about a quarter tank. Within minutes the car idled on its own. After which I drove to the gas station and filled up. I’ve been using B-12 ever since.

It looks like the berrymans is penetrating metal not just the carbon, The seafoam looks like a more gentle approach, you can still see the shine from the valve afterwards

[@tarquineous]

It's the oil in the Seafoam compared to oil stripping of the Berrymans.

[@grational]

Yes- looks caustic and oxidizing. The missing variable is the outcome in it's heated diluted phase. Heat changes the chemical stucture-activity of virtually everything. The Berrymans looks like it contains acetone or the like. Concentrations would need to be considered given poly parts. Also, the ideal scenario is to not get clumping but dissolving, which may seen at odds with each other, and has to be considered given how far the engine is 'gone'. Def a fire hazard- rags etc.

It is actually toluene. a widely used industrial product in the lacquer industry, parts cleaner in some dealerships and thinner/like solvent for paints and used as an octane booster among others. It would seem successful at removing gas varnish from old - bad fuel .The advise of one person, to use in a tank over a long drive, seems like the best option to minimize exposure thus potential damage. Combustion effectiveness is always a factor. This guy (article below) does not seem to find it successful overcoming poor designs however. Common sense, not apparent today given the longevity of synthetic oils, does not consider ever-present combustion pollution, of course made worse with poor design. It always helps. Consider changing oil more frequently always. A worst case example-s of manufactures better and weaker designs of GDI. www.enginebuildermag.com/2017/10/solving-gasoline-direct-injection-issues-facts-fictions-gdi/

Not to mention berrymans ate his gloves, what do you think that's would do to gaskets and intake seals? Sea foam is more gentle and safer for your engines. Sea foam is meant to be used for the long run in your fuel. It will prevent carbon build up if used regularly.

[@ryanmoore4098]

This was more scientific than you might think BundysGarage. I’m going to start using a combination of the B12 and Seafoam’s “Hot Soak.” Well done video!

[@cruisin8221]

I've been using berryman since the early 80s to clean carburators. berrymans blasted dirt and stains that gumout couldnt.

[@weljo2001]

I'm 56 years old and have been using Berrymans B-12 since i was a teenager in my cars and motorcycles...

[@bundysgarage]

It works! I have seen it first hand

[@arthursmith643]

weljo2001 check out using Marine 2 cycle TCW3 rated outboard motor oil at 1oz per 5 gallons of gas. Google. Been Testing Oil and read up on it. Sarge and team have done the homework for us. I've been doing this for over a year and it works very good. You wouldn't know my car was running at idle. Easier starts because it lubes as it cleans. It must be TCW3 rated not just any two cycle oil. Works better than MMO or Lucas. Must cheaper. Walmart has there Supertech Marine 2 cycle TCW3 outboard oil at around $13.00 a gallon.

[@weljo2001]

Thanks, I'll have to check it out

[@JOHNMORIN100]

The results are in and you did a fair shake Barryman's in the lead thanks for taking and sharing your time and effort

[@ladrakeus9252]

Not to mention, by bie rubber and plastic seals.

[@bundysgarage]

You really think they would still be in business if their product ate seals?

[@MrHewilson2]

Interesting test. TY for presenting that. It might be even more instructive to repeat this but with the cleaners at the dilution they would be when mixed in with fuel at 1 or 2 oz per gallon rather than at off the shelf strength.

[@boots7859]

I like SF, however it is what it is. Both compared at 100%, Chemtool seemed to nuke the carbon and its bond to metal much, much better than SF. Diluting to manf. spec would probably require a month or 2 to see results. And more than likely the results would simply show Chemtool attacking carbon more than SF. This is a 'maximal' type of test.

[@jameswarner300]

I've used both, and the one thing this guy isn't telling you, from my own experience with Berryman, is that it will eat literally through your spark plug ends. Seafoam works much much better. Berryman is extremely tough on other aspects of your engine parts. I begin having to change my spark plugs like almost a week to 2 weeks after using Berryman, so no I wouldn't recommend this product, but thanks though, nice demonstration.

[@jameswarner300]

@Steve Silvas Yes you're correct and I didn't know that.

[@jamesj.litteriojr.433]

No worries bro!!! At least you took the time to do this test. Obviously to me...Berryman's. But heating the products up like one of the commentors below would definitely help...Considering the engine heat. Thank for the video! :)

[@bdrrogers]

Both of these were used full strength. What are their recommended dilution ratios in gasoline? If one is recommended to be used at a much higher concentration in gas than the other, that may alter the results a lot.

[@westcoast3595]

Berrymans has been around for many years. It works great helping to get rid of carbon build up.

[@5hawks]

I don't think you can beat B12 for cutting gasoline varnish/dirty carb./old dried bearing grease/stains/ink/paint, just about anything. I used it on an old 352 that was parked with gas in it for 17 years, rings stuck, compression 50 psi on #8. Filled the cylinder with B12, now it's one of the strongest cylinders. B12 and Mystery oil, best. But I doubt that B12 will have much effect on internal engine carbon.

[@caroltenge5147]

B12 works. For $3,19, its the best there is.

[@pbr549]

Liked the video looked up the Mobil 1 on the grill. With 25% less weight it made sense the Mobile 1 started to burn first.

[@rodneygreen9968]

Very informative video on the comparison of products. Berry ate though the gloves. WOW! I'm skeptical on what it would Do To GASKETS. I'll stay with SEAFOAM, to be on THE SAFE SIDE.

[@terrywatkins4498]

Rodney Green I agree

[@bundysgarage]

Do you really think Berryman’s would still be in business today if their product was eating fuel systems! Come on man!

[@terrywatkins4498]

BundysGarage Well you do have a point. I was wondering will this help my carburetor from Sticking?

[@ray32825]

I have a 1999 Toyota Corolla with the same problem. Fortunately I have another vehicle so I don't drive it and therefore I can soak the pistons for long periods of time. I have been following this issue online now for years and I think the best solution is to get a piston from a corolla engine with this issue and soak it in ADV.99-05 FAST LACQUER THINNER, BERRYMAN CHEM DIP, CARBON-OFF, or PISTON KLEEN to see the results. After that try it on the engine and see how it does.

[@jasonl8326]

For what it's worth, my mechanic said B12 is a much better product than seafoam. I've always used seafoam (mostly because it's more available) and have had good results, but I'm gonna give B12 a try and see if there's a difference (Amazon sells it but I usually don't see it in stores).

[@booradley1065]

[@supercraig2009]

Will this be safe chemical to clean catalytic converter?

[@danielvillarreal8892]

Great info. Definetly will use berryman from now on. Had been using MMO.

[@tbone4u100]

I would go with berrymen's, it seems like it came off more easier than the seafoam. But all in all seafoam didn't do a bad job.

[@psdaengr911]

... on the bench.

[@maryestheraustin2505]

I have used it as a truck driver in the Army for more than a decade.

[@5hawks]

B12 added to your tank is such a lean mix that it doesn't attack the rubber parts.

[@5hawks]

Yeah, I've only read 1 or 2 comments here where anyone actually used it in their tanks at the recommended rate. It will clean the fuel system without harm but not many modern cars need their fuel systems cleaned. Gasoline is a very effective varnish cleaner. And as I already posted before, I doubt that B12 has much effect on internal engine carbon such as on piston tops. Baked on carbon is tough. Carbon below the valve heads is mostly stuck on in a matrix of flash dried gasoline so the soak test wouldn't be applicable to piston top carbon removal. One of the most effective ways of removing baked carbon is a water steam which has been used for a hundred years or more. The hot, dried porous carbon absorbs the water on the intake stroke then instantaneously turns to steam at ignition and breaks the bond. Where B12 shines is parts cleaning. It used to be sold in aerosol but it's flammable and a health hazard if not used carefully. Like anything else, you have to know what products are appropriate on what materials. I've used it for more than 30 years but I no longer use it or any cleaner in the tank. If a modern engine doesn't run right B12 isn't going to fix it. It needs work by a skilled mechanic that knows wtf he's doing. (sensors, all kinds of them) I've never used SeaFoam. It's probably a good product, so is MMO but none of them are "engine overhauls in a can."

[@randystiles230]

Wow finely some one that talks the truth! I am a GM mechanic The 3.6 has a very big problem with carbon on top of the valves! and direct injection has a lot to do with it No fuel or additive going over the valves!

[@bundysgarage]

+Randy Stiles all the GDI engines, Mazda, Mercedes, BMW, GM (3.6L), Ford, Kia, Hyundai, are experiencing carbon on the valves and pistons. Also the rings stick on them and we are seeing oil in the upper intake manifold as well. Piss poor design!

[@twinturbocoyoteftw]

BundysGarage Have you ever used any BG products? They have a great direct injected service kit that works well on sticky rings and valves full of carbon.. This is a big problem with the eco boost and I have had my customers on the 44k from BG for awhile and its far superior but costs more. Good video though

[@bundysgarage]

+Mustang Guy363 yes BG is a great product. My name is Bundy and I support this message.

[@puffnstuff12]

I also use the Berryman's B12 and recently I had to replace the head gaskets on a lawn tractor and generator. I used it to clean the top of the piston and head from both of these engines and it just dissolves the carbon buildup right away. Gumout carb cleaner also works well in this application but the Berrymans's is better at cleaning the long term buildup.

[@bundysgarage]

+Gregory Phillips I have seen it first hand clean out old carbon buildup inside an engine.

[@neilwilliams8608]

You need heat, friction and pressure for accurate results. Awesome video. Thanks a lot.

[@ianmalleau3398]

Great review. Good info to know. Thanks Bundy!

[@raygranda2474]

If Berryman's ate at the gloves, how about rubber hoses in fuel system? I ride a Road King and have been using Seafoam. I'm a little Leary of the effect Berrymans had on your glove but impressed with how it dissolved the carbon compared to the seafoam. Thanks for the video!

[@guntimes9908]

Ray Granda your fuel lines will never have pure B12 just sitting in the lines for 10 days.

[@raygranda2474]

True.

[@bundysgarage]

+JAY WAYNE why does everyone forget that fact watching this video. Gas lines are made to handle gas, they can handle a little bit of B-12!

[@codemiesterbeats]

you have to think it is not in solution with gasoline its 100% so its going to have more pronounced effects on everything. I hate the fact that seafoam doesnt tell you what is in it... berrymans tells you the main ingredients right on the can. I wished automotive products (esp fuel/oil/etc additives) were required to list the ingredients...

[@davidfloyd6084]

only thing that eats fuel lines is idiots, e85, and ethonal

[@sreekumarUSA]

Good to see the experiment. There's no negative comment to report. The experiment was a straight forward and simple procedure. The Carbon deposits came off the valve and its stem from B12 solution. Now the question is after the solid deposits are drawn into the cylinders and blown off through the exhaust port, 1) what happens to the deposits, eventually? 2) Will it clog the CC mesh impairing its function? I will be using neither of the solvents but Liqui Moly Valve Clean. if any one can provide an input regarding CC clogging, that'd be appreciated. Thanks.

[@bundysgarage]

I have heard that BG breaks off carbon so well that the chunks are large in some cases that it does clog the CATs

[@sreekumarUSA]

BundysGarage Thank you and appreciate the response.

[@SuperSharpBlue]

Great experiment! Something I wanted to point out is that it makes sense that seafoam is "weaker" as it is made to be added into the oil/crankcase, and shouldn't harm the seals. Note how the Berryman's melted your gloves, imagine what it would do to seals if it was added into the oil/crankcase. Not saying one is better than the other, but it is clear that they have different purposes depending on what application you are using. I would recommend seafoam for a light engine flush and to keep new cars clean, while I would recommend Berryman's on older vehicles which have more carbon deposits.

[@tarquineous]

It evaporates very quickly, especially when the engine gets hot. May be good into the pcv valve, let soak for a few minutes. I don't know about 10 days!

[@LawnWolf]

I mix the two for older trucks that have sat for along time. I put it in the fuel and the mix works really well for cleaning the carb.

[@billmalec]

I use gasoline sent into the engine via a carb or fuel injectors. Been working great for 40 years now...

[@bundysgarage]

+Bill Malec yep most people do

[@thedrunkmonkey2254]

I used Berrymans three weeks ago for the first time and saw a difference in the performance of my 2001 Dodge Ram within 40 miles that I have driven for over 12 years using Seafoam I'm sold on the Berrymans B12 Chemtool and the Berrymans is half the price of Seafoam.

[@curtischao9392]

looks good. thanks for doing the job.

[@WISHBONEL7]

As we all can clearly see , on both the valves and your " glove ", that *Berryman's is the absolute best* . It is the only one that I use in gasoline engines .

[@charliepearson1678]

I believe ill stick with Berrymans .

B-12 is cleaner for carbs vs lube that seafom. Both will clean b-12 will clean better but offers very little lubucatuion. I wash my dishes with b-12. Very good video.

thank you i really appreciate the info! Go B12! 👍

[@EstablishedLowriders]

Thanks for the comparison test!

[@michaelgallegos4884]

Berryman B -12 the bomb cleans carbon great !!

[@jeremyventurino9481]

Seafoam is pale oil, isopropyl alcohol, and naptha. The Berrymans is made from acetone, methylethylketone, and toluene or something. Completely different makeup, but the seafoam seems a lot safer to use. I don't know if I trust paint thinner and other harsh chemicals, but for short term use it may prove helpful to some.

[@DwightMS1]

Hey Bundy, I have an idea for a way to shut up the "experts." Fill a jar with a mixture of gasoline and B-12 like you'd put in your tank, and place a few rubber parts from a fuel system in there with it, for 10 or 20 days, then show them how the parts are still intact.

[@RockandrollNegro]

It still wouldn't be a true gauge of performance, because (1) the mixture isn't heated like it would be in a fuel system and (2) there's no ignition/combustion taking place. About the only way that you can really get a good understanding of the performance is to do the 100% jar test here, or do a before/after borescope vid like ChrisFix did. I don't think he tested the Berryman tho.

[@hpt08]

@@RockandrollNegro surely if the fuel is heated before it gets to the cylinder you'll be worrying about a hell of a lot more than rotting plastics 😁

[@elij.s.7580]

Im about to put some in my motorcycle's 5 gallon tank, one ounce per gallon so 5 ounces. My only fear is the float needle and seat partially deteriorating and then flooding the entire intake with gas. However, I feel like Mr.Berryman wouldn't put "Fuel Injector and CARB CLEANER" right on the can if they knew it wasn't safe. They seem to make specific products for specific uses.

[@bundysgarage]

It’s not going to eat your fuel system.

[@Seriouslydave]
