20 TH-cam Repair channels to watch in 2020: blog.feedspot.com/auto_repair...
Professional mechanics and do-it-yourselfers everywhere rely on this product every day. Sea Foam Motor Treatment dissolves and cleans fuel and oil residues and deposits, stabilizes fuel, controls moisture, and lubricates upper cylinders. Safe and effective when added to gasoline and diesel fuel and oil crankcases - Just pour it in!
Berryman's B-12 Quickly disperses moisture and dissolves gum, varnish, and other fuel residues from the entire fuel system, fuel tank, fuel lines, fuel injectors, valves, rings and pistons with H.E.S.T. Regular use ensures higher compression, fewer repairs, lower operating costs, and increased spark plug and injector life. Available in both consumer and commercial sizes. Catalytic converter and oxygen sensor-safe.
HEST - “High Energy Solvent Technology,” a Berryman exclusive, incorporates the use of strong solvents, as opposed to weak carriers and diluents such as mineral spirits or kerosene. As a “tip of the cap” to our HEST technology, positive feedback regarding any of our products is affectionately referred to as a HESTimonial.
Lucas Deep Clean is blended with an exclusive Lucas additive package and specific carrier fluid that contains no diesel fuel, kerosene or anything else that can be harmful or useless to an engine. It also reduces NOx emissions, eliminates the need for higher octane fuel and deep cleans the entire fuel system and combustion chamber.
Filling up with a Techron fuel is always an upgrade, because our research and development never stops. At the Richmond Technology Center, our team of chemists and engineers test and retest Techron's effectiveness in all kinds of engine and vehicle conditions-to bring you results that are far from standard.
If you regularly use a high-quality gasoline such as Chevron, Texaco and Caltex, you probably don't need Techron Concentrate Plus. However, should you occasionally fill up with lower quality gasoline, you may need Techron Concentrate Plus to help clean up deposits that can build up over time. In addition, if you have an engine that is sensitive to deposit formation, or if your vehicle is regularly used under severe conditions, you may also benefit from using Techron Concentrate Plus.

I like chemtool...just used it to clean my intake valves and it seemed to work pretty well...plus chemtool is $3.50 compared to seafoam at $9.00
SAME HERE.
There is a reason for it being cheaper.
+Wayne Bradish what's the reason?? Do tell?
Think
Sea Foam is expensive? Try a can of 44K.
Money Mac how do you know it cleans your valves?
I've always used Berryman's B-12 over the past 50 years because it works and is very affordable when purchased in 1 gallon cans. I did use Techron Concentrate once to see if would free-up my sticky fuel level sender. It did loosen up enough of the crud to get it working much better with the detergents in top tier gas finishing the job.
"This might dissolve my glove" ( rubs chemical with bare hand)
@Barry Allard California was right all along
Barry Allard I need to stop doing that then
Skin is very good at absorbing 🧽
Don't put in your contacts for a week.
I keep all of my lawn equipment running like a top by pouring a little 44K in my gasoline tanks each Spring.. My mower is 26 years old and never had any carb work.. I also use 44K in my vehicles.. GREAT STUFF but the price seems to go up regularly..
Berryman is what I use in my Honda Odessy, I have great results with it
Thank you. Like your honesty.
I worked on my old carb jets on my Honda magna, with the Berryman B12, that stuff rocks 👍🏼
Sometimes chemical reactions take activation energy to proceed, so just because a cleaner is great at room temperature doesnt mean its better than a cleaner that did less so at room temp for this test. A different cleaner at the higher temperature may outperform others during actual warmed conditions. The best way to test these is conduct the experiments in an electric heating oven with lots of fire safety, fume evacuation...etc. The product that works best at room temperature may break down at high heat or not react at all or other results as experiments will only be able to show. Also, a product that works at 'room' temperature might perform better in northen climates or colder regions as one may see the thermostat at normal temperature, but the top of the engine where the cold air adjacent to the valves are might cool down to room temperature quick and thus the 'room temp cleaner' would be a better product.
For test to count as valid it must be executed in an authentic enviroment. (in a running underperforming system)
Bg44 k excellent product for cleaning carbon deposits
I also use techron. I love it!
That last comment made, I applaud the efforts of the video to shed some light on the effectiveness of the products.
I've been using the Techron for the last 25 years and trusted this formula since Chevron began putting this in their Fuels. I now add 1-2 small drops for each fillup in my Lawn Tractor. Last week I decided to replace my Spark Plug in my Tractor and it was just as clean as a new plug, worn out but clean! I also add one container in each of my Jeeps after the third fillup. MPG inproved by 2-3 gallons. Power also inproved. I do know Chevron works best during combustion!
Thank you for the video brother I use for my car B-12

I just had my mechanic do a three step fuel cleaning service. I found out He uses BG that's great news!
How much did he charge you to do that?
@@bundysgarage 180
😳😳😳😳😳
Been using Berrymans for years and my Spark plugs are also very clean.
Thanks for your helpful video!
The 1st thing I do after getting a new vehicle I always throw a can of Lucas in it....
The 2 I use and like are BG 44k and B-12 both really worked for me over the years, I have tried the others with minimal results compared to BG 44k and B-12
I was having a problem with my scooter cutting off on me in the middle of traffic! I tried Lucas same problem!! I tried a cheap brand from Discount Auto parts it's been a month now no more problem!!!
Glove test was such a smart idea thank you!!!
Glad you liked it!!
Hello beautiful eyes
Have used a number of cleaners available in Australia. Techron and Redex have proven to be the best in cleaning the system and found more than a noticeable increase in fuel economically.
Chem tool on the valve seems to have had eaten the carbon which might be the reason why there was less on the shop towel. I know from plenty of experience how well Berrymans works on cleaning engines,it works!
This is a great test! Fuel lines are not the same as gloves, B12 will not hurt them. Mixing any of these cleaners with fuel only dilutes them. Running it through the injectors under pressure only gives the diluted cleaner less time to work. And for the guy that said no one uses the cleaner straight, I say why not ? I pulled my injectors and filled them up with B12. It works! Also had some injectors that had sat for years with fuel in them and were completely clogged solid. I was able to dissolve that and get them to flow like new.

I did my own personal studies with different products over the years. So far Tech Ron is the best monthly use and BG44k I use every six months as a booster. Nothing truly cleans first time around but with monthly usage, you see the results. Techron and BG44k in a RAM with over 200,000 miles is my pick.
Techron is what Chevron puts in its gasolines. I would use Techron before messing with Berrymans. Berrymans has acetone in it and that’s the chemical they put in fingernail polish. It’s very strong. I believe Techron is the best stuff to use. Top Tier gasolines won’t hurt either.
How about STP fuel system treatment? Why was it not tested?
Thanks so much for the videos. Helps.... What should I used for my RAM 1500 2017 45,000km
B12 it works really good
Interject injector cleaner is the best I have ever used, keeps injectors in top condition as well as keeping valves carbon free , they make both petrol and diesel cleaners.
The additives are designed to react with the gasoline. The Berrymens B12 would be diluted in the gasoline and probably not eat your glove. Also they may need heat to help get their cleaning mojo going. If they're fuel injection cleaners, they will work better under pressure. But it was a entertaining video. Well produced. The infomercials people maybe calling
Bg44 k platinum
Well I decided to clean my injectors the cheap & easy way.
I’m gonna throw in a half quart of transmission fluid with a full tank of regular Arco gas when I fill my Toyota Tacoma tomorrow. used to run a quart in my semi truck that did awesome things. I’ll let you know if she blows up.
put a little lucas in mine today and after 30 miles driver I can report a noticeable improvement in acceleration. It seems like the engine is less sluggish.
Put it in your fuel tank.
Heck, my own sweat weakens the 5-Mil thick latex gloves, so I bought a box of 7-mil thick latex glove - they rip too. I don't know which fuel injection cleaner product I will use, but I use Marvel Mystery Oil periodically when I fill up my gas tank.
Never had any luck with seafoam but always get great results from Barrysman's.
BERRYMAN IS THE BEST
ME GRAMPS PUT IT IN ALL HIS TAXIS= 🚕🚕🚖🚖FOUR HAVE OVER 700.000 MILES
I use Shell gasoline in Power mowers & In Vehicles & run a good fuel injection cleaner . I just tried Redline & this stuff works . I’d to try BG fuel injection cleaner .
Lmao I like how you talk about these things eating gloves then proceed to pour some on the glove then use your bare fingers to rub it into the glove and determine if it's going to eat through that glove. Good stuff man.
Bg44 k platinum
What would work best for a 2016 Nissan Maxima? Or recommend
So dissolving gloves... and fuel injector orings, gaskets and seals is a good test?
I personally use the original Marvel Mystery Oil ($3-4 for four uses) in my gas tank and crank case. Every year or 30K miles I will use B-12 Chemtool ($3-4 for one use) as strong solvent as engine flush and fuel system treatment.
Randy Thornton how is b 12
I have a 2009 KIA RIO LX 4C 1.6L with 134000 miles. I purchased the car when it had 84600 miles. My opinion is not base on any scientific experiment, but I feel Royal Purple fuel system cleaner is doing it's job. I just have to add that I only put Shell 93 nitro in the tank. The engine "thanks God" is still performing well. Thank you.
Would someone please explain to me how many rubber or syerfoem parts are found in engine and fuel systems? Thanks for your consideration
Which product is most appropriate for a motorcycle that's been sitting for a couple years?
Techron is what I would use. It is always in the top rated in testing. You want something that cleans slowly not something that will remove chunks of carbon. That can cause serious problems
BERRYMAN IS MUCH BETTER! COST LESS TOO
I love this video im gonna subscribe to your channel
I remember seeing the previous video where the b12 ate through your glove. I got a bottle, but now concerned what this stuff will do to the rubber in my fuel pump.
Simple, only use it on a long trip. So you can run the stuff fast through your fuel system. This will also give you the best results. I have never had fuel system issues when using it in this matter. If you can't take a long trip add it to half a tank of gas and run up and down the high way till the gas light comes on. B12 chemtool will clean your system. If your really concern about the fuel system run a small bottle of marvel mystery oil through afterwards. Years ago. They use to sell a dip can of b-12 for mechanics to do overnight soaking of parts. It was miracle stuff for mechanics back in the day. If a mechanic could not find the part readily available and the customer needed the car back soon. They would throw the part in the can and hope for the best. 9 times out of 10 it would fix it.
There's a huge difference in chemical resistance between nitrile, vinyl, latex, and rubber. For example, a chemical that melts latex won't do a thing to the others. Just because a chemical melted his glove doesn't mean it will melt components in your fuel system.
Which one works the best for cleaning injectors. I usually put the b12 in my fuel
B-12 Baby, I think that's the best for injectors.
i think the berrymans works better .. i had a car that had hesitatation with the acceleration and i used one bottle on a tank ful and it made a noticeable difference in performance and better gas mileage .. i just wonder if its ok to use it in a regular basis or not .. your thoughts ?
You should try the same test ,only with the valves hot . These cleaners all work alot better on a hot surface.
I have been using the Chemtool for a while now my next door neighbor who does everything like rebuilding engines on the side said it is all he uses that is after I told him I used it.I have used Lucas a lot too.
Mark's Reviews and RANTS ok ok b12
Bg44 k platinum
It's B-12 Chemtool for me. If there's any non-metal parts in your fuel delivery system, that material is as inert as the Berryman cap and protective stopper is made from, which is perfectly safe to have the product be on.
So isn't the combustion itself also a part of the cleaning? In terms of the additives will/would react during the heat and pressure?
As soon as I saw he didn’t mix the products with gasoline the way these products are made to work the test is worthless. Nobody runs 100% additive in their engine.
I wouldn't put it past this bloke!
Exactly. If it works in conjunction with fuel & combustion then what? Plus, look for carbon residue in jar bottoms too.
Never thought about that vary true
yeah what a butts pissdick
@Steve Silvas see the Project Farm TH-cam videos for maintenance tests. He comes up with better test methods. I use the Berryman B-12 Chemtool, and he got good results for Restore in the engine oil for old worn out lawnmower engines. Fuel system gaskets are made to be more resistant to fuel and fuel cleaners, especially newer vehicles made to run 10 percent ethanol gasoline. For winter storage I use Startron from the Walmart boat section, it seems to work a little better than the Seafoam I used to use for this. The Berryman B-12 Chemtool has more carbon dissolved in the liquid in the jar, instead of still on the valve.
How about the sparkplug? Does it need to be cleaned also ? Thanks for answering whoever you are :)
i like other lucas products so i will probably use that. thanks glad i didn't have to spend all that to find out really they are not that different from each other. i trust lucas products.
... i've used Berryman's for several decades.. i didn't see any reason to change that. besides, none of my valves wear gloves. ;)
hahahhahahahahahahahahah
i always used Berryman b12 always does good for me seafome cost a lot more . i'm sticking with Berryman.
LMBO LMBO LMBO 🤣😂😂🤣🤣😂😂 this one was funny 😝😝😝😝🤣😂🤣😂
Very good informing video THANKS
You are welcone
I use Lucas products" they always worked well for me.
I use Chevron with Techron, it has P.E.A. I've used in 2006 Scion xB since new. My car has 320000miles and I drive it to work 50miles one way.
I would have to agree on the limitations of this test. These are not mixed and diluted with fuel and heat is definitely an issue since they can change with heat. With this test you could have had a pure water control jar and it would have removed the carbon, but nobody is going to put a can of water in their gas tank.
nice video...god work.I prefer 91 % alcohol. 3.6 VVT DI loves it!
Hello !!! Could you please give me information if exist an special cleaner for automatic transmission?? Without remove it! Hondaacvordv62001 4speeds.
Thnkss!!! Mine starts to show me code p0730.
Good video work, the effort is clear. But the reason those valves are essentially spotless to begin with is the gas contains a PEA detergent designed to work at the extreme temperatures and pressures of an internal combustion engine. You can't clean up what is already clean, and you can't replicate an internal combustion engine test in a jar....well...you could.... but it is better known as a Molotov cocktail.
I have used Seafoam for quite a while on a 2005 Ford Fivehundred. The ford was showing a code of the left bank being lean. I used Seafoam in the fuel for a few miles, cleared the code, and it never came back!
Had my truck sitting for a year and ran old gas thru it and it cloged up my carb ran some b12 thru it and after so long it seems to helped but this is just me
I love B-12!
Chemtool and Techron are the best!
Only ones I’ll use in my Hemi!
Use gumout Tune Up Muli System cleaner. 💪
I’d love to see the same test done with StarTron, Mechanic In A Bottle, and Ethanol Shield.
First time I was made aware of Berryman B12 was like in 1974. I had just filled up with gas at like a Fast Gas place, cause it was much cheaper. Well onway home after a bit, I was going up hill, and my 1972 350 engine started running real rough, shaking the car (a 1972 Monte Carlo) and I looked in rear view mirror and frigging smoke (was night so don't know the color of smoke) was all behind my car. Freaked me out.....
then got past hill and I don't recall more smoke, but the engine continued running rough allway home. I went in and told my dad about it, and said I got bad gas... apparently had water in it. He said I needed to get some B12 and put in it. So I did, let it sit overnight, next day got in car, and it was running just fine then... so never went back to Fast Gas, only used name brand gas in car. Never had that kind of issue since. But I still use B12 in the '72's I drive to the day. Have never owned any other kind of car than a 1st Gen Monte Carlo... Way more economical to drive... Ok, I do not get 42 miles to the gallon... but what your paying for a new car, hell... that would buy a lot of gas, roflol. Plus... your "good car" you drive.... Sure would like to see that driven everyday for 50 years and see what kind of shape that yellow headlight car would be in right now!!
B12 is the $HIT!!!!
@@bundysgarage It's the BEST!
Great job.
You showed the valves. Which is better for injectors?
Doesn't heat and engine revolution change then chemical process of each additive? That along with high octane fuel
So what does B-12 do to seals?
Think we should keep it out of our fuel system?
If B-12 destroyed seals they would be out of business from all the lawsuits from customers having their seals destroyed. I've been using B-12 for over 30 years and not a single issue.
How about Marvel Mystery Oil additive and Gum Out Total System Tune Up ?? Have you tested them to see how they compare to these ??
I have not
Someone needs to do this test with heat and combustion/injection pressure. I'm not a chemist but I know as much that different chemicals don't behave the same at room temp and/or high.
You could be looking at BM's as not having much carbon on the paper towel and find that it's eating carbon a lot better at running temps.
After watching a bunch of vids on this subject, I feel like I have more questions.
Also I'm developing a concern for the Cat converters. They have very small passages inside and if a larger chunk of carbon deposit breaks off from inside
the engine, what's to keep them prom plugging some holes in the CAT?
I spent good money on mine and a day installing/welding them.
I'm leaning towards just biting the bullet and getting new injectors.
To date, none of the "pour it in the car" type magic goops worked for anything ...
For instance, no stop leak of any kind did any good. EVER!
Tried coolant stop leak -> Ended up having to do the head gasket job (Thanks Honda!)
Tried AC stop leak -> Had to change compressor (and dryer)
Tried Steering stop leak -> New pump did the job
Done with snake oils ... (JMO)
What's next? Brake fluid leak stop? :)
No, windshield washer fluid stop leak 🤣
Sounds like all your cars was junk.
Not unlike pharma for the most common chronic lifestyle related diseases and their lousy misleading irresponsible commercials, eh?
All of these different valves were sitting in solutions at different concentrations. This was not a fair test. You should’ve made a solution of gasoline and fuel system cleaner that was the same concentration for all of the different valves.
Bg44 k platinum
Berryman's has acetone and toluene. Those are very strong dissolvers of softer plastics and rubber like gloves. Good for fuel systems diluted with gasoline.
William Riley
Wonder if these products have an affect on the newer plastic intake manifolds??
I've been using Marine outboard two cycle TCW3 oil for almost two years. It works like Lucas fuel conditioner and MMO. Google. Been Testing Oil LS1 GTO. It has the write up on testing and results. Its 1 oz oil per 5 gallons of gas. Works great try a few tanks.
1 oz in 5 gal seems light. Are you sure you can see a change?
I'll get to the point. Anything with PEA is a must.---and then use Marvel now and then to semi clean. Sea foam is a good cleaner too a few times a year.
So what do you have against Berrymans that you do a particular tear on that glove? That looked pretty biased to me.
This is a better test, seems like they all work , other people test , keep saying they don't work as advertised but my personal option , you run a car for hundreds of miles with build up and expecting it to be clean with just one try, is expecting too much ,
Roger Chien You won't notice any change if your engine isn't filthy to begin with. Even then, that's assuming it gets in the way of its running. My old Toyota runs about the same after as before, but now she doesn't misfire if I put my foot down in lean burn mode (one of those quirky 7A-FEs :D)
Roger Chien believe me if one treatment cleaned your entire fuel system all these cleaners and additives would be out of business.
@@paulsosa1872 best answer of all!
Aren't these fuel system cleaners primarily for cleaning fuel injectors and carb jets and needles? Wouldn't a better test be to use them on an injector test stand?
Other day I had the bright idea to put a can & a half of Berryman B12 into an empty Marvel Mystery oil jug I had laying around because the MMO has Oz. Measurements on the side. I thought this was a great idea to be able to measure out the B12. By the next morning when I went into the garage that jug was laying in the floor. It had fallen off the shelf. Why did it fall off the shelf ?? Because the MMO jug was now the consistency of a water balloon lol. The B12 overnight had softened the plastic MMO bottle to where it had zero rigidity left. Just like a water balloon. I knew it was a strong chemical but DANG
BG 44K is VERY GOOD. However, the fuel additives designed to release dissolved hydrogen gas are the best !! The hydrogen gas ignites and creates a high combustion temperature which knocks off the carbon deposits which condensed at lower engine temperatures.
which ones
I got the best results on bg44 k platinum add to a full tank of gas the longer the product is in the tank of gas the better results
So far I have used LUCAS, and SEAFOAM. I used some seafoam and my catalytic converter top rattling. No BS. I am going to try some B-12 soon. Thanks for the VIDEAO
the Seafoam and Lucas look like they did the best in the cold test? but I admit I expected better results from all of them maybe in the engine under fire and heat some of these may have done better than a cold test? or over several treatments maybe all of these would have had better results-we may never know
Is dissolving gloves a good thing?
What would be the best test is to take heads off and show the valves first. Then put back together use the treatment and see which treatment works in an actual running engine..
Thank you for sharing. * Your glove test was like watching the movie "Jaws".
Been using B-12 forever in my 99 camry 2.2L. It's one of the only cleaners that actually burns when ignighted.
Yes Barrymans is the $hit!

Does anybody know if Techron will hurt the turbo on an ecoboost?
Did It eat the glove or did It dry The glove out?
be careful with making assumptions about the results where heat would cause better cleaning performance... remember that during combustion these products produce their own oxides but you are right that the operating temperature activates the product. I subbed and enjoyed the video. Thanks for doing this test. Anything with petroleum in it will eat a latex glove.
You should have pulled the valves one at a time from the chemical and then wipe immediately.
The BG44K looks to me like it did the best.
Berrymans B12 fuel injection cleaner is the best
Sea Foam and Lucas look like they're the ones I would go for. But gas also seems to remove some buildup as well. Like anything, it can take a few cleanings to remove buildup of carbon, deposits, etc. so I'm wondering if some of the bottles should be changed to reflect that their cleaner works but due to varying amounts of carbon or whatever, it may take more than one treatment or a certain number of treatments for full dissolving/cleansing to occur. Thanks for testing the products and showing the degrees to which the cleaners are effective under cold conditions.
By law, all gasoline produced in the USA have to have detergents in them.
I have read that Sea Foam was formulated for 2-stroke boat engines and doesn't help when there is ethanol in gasoline?

I used Easy Off oven cleaner to save a scorched pot. Worked extremely well. Hmmm....Ya think?...I know for sure that stuff works amazingly well...lol...
What do you know about Berryman's TOTAL? I have had very good luck with it. Please reply, thank you.
I’ve never used it. What is it?
@@bundysgarage TOTAL is Berryman's top of the line product. It will bust carbon better than B-12 Chemtool. I live in Texas and it is in parts stores here and has been for about 25 years because I was using it in the mid-1990's. It is priced with Seafoam at about $8.00 a bottle. I have had very good luck with it.
Tulene is a solvent and octane booster. They use it for paint thinner for the thick parking lot paint so it will run in the sprayer. It will clean fuel systems and increase the octane. I used to run two cups per 5 gallons of gas in my crotch rockets. Exhaust smells like bandaids or gauze. My pipes always smelt like freshly wielded metal it's high octane booster and cleaner burns all the carbon out
What about cleaners with p.e.a, redline, gumout etc
Why does nobody ever test how they clean FUEL INJECTORS. Im sure most people care more about that than valves.....
Most people are wrong...
If you're with your right mind, you WOULD care MORE about valves... Any injection cleaner does the job... Very few, if any valve cleaners do anything whatsoever... And once you get carbon buildup on your intake valves, the rest is a landslide... All the way up to rebuilding your engine... To present day, on DIE only walnut blasting sorts the carbon buildup issues in a satisfactory manner. The rest is either make believe or postponing the inevitable...
Disagree, as both products clean
Your talking about gasoline direct injection with walnut cleaning. No fuel additive in the world will clean that. It’s a design flaw caused by a lot of the manufacturers. Fuel is no longer sprayed across the top of the valve. It is injected right into the cylinder now. Toyota is the only only one that has 2 fuel injectors per cylinder. One sprays on top of the valve to help combat carbon deposits and then the other injector is sprayed right into the combustion chamber. Other manufactures are catching on now but the first few years of the GDI engines were piss poor.
@@bundysgarage Been rebuilding my Audi's 2.0T FSI... and at 113k it had over a quarter-inch thick chunky carbon on the exhaust side, which reduced the holed from about an inch in diameter to a half inch, and about an 8th inch thick on the intake side because of the PVC and EGR systems... Direct injection is complete crap. Just redid the exhaust manifold and intake gaskets on my Suburban, and saw less than 1/4 the total carbon buildup at 240k miles... it's basically just a surface scale, in a 5.3 liter. Yeah, they need to stop designing engines to fail...
I agree we should see a more well rounded review... these are supposed to clean from the tank all the way out... id go as far to see how it affects oxygen sensors as well... we all know what octane booster does to O2 sensors... curious if injection cleaner has any effect.
