We Try Seafoam - We Come Away Shocked 

I have used it many times. It will work on minor stuff, a little varnish, a tiny bit of water contamination, but it has limits. It will not take those carbs from how they were at the beginning to running fine. Your cleaning is what made the seafoam work.

I'm 49 years old now. Back in the day when I was 10 years old, my uncle was an aviation mechanic and he recommended using Sea foam on our dirtbikes; it actually worked wonders! The main thing was to actually get it circulating into the systems of any combustion motor including lawnmowers, and it would regulate a smoother idle! Take care uncle Tony, and enjoy!🌄👍

I've been using it for years. Works great. I use a whole bottle for 25 gallons for winter storage and also during the cold winter months in my daily driver.

"I felt stupid buying it!" UT at the store: I'm buying this for a friend... 😄

Bought a 25 year old Gold Wing that had been sitting 4-5 years. Idled and ran rough even with fresh gas. Dumped a whole bottle of Seafoam in and filled up with gas and went for a 30 mile ride. Idled and ran smooth as silk; even the idle surge is gone. Yes, you can set a nickle on edge and it won't fall over.

I bought a Harley that sat for 11 years. Everything you said also applied to my situation. I used Lucas gas treatment on three tanks and now the bike runs great. Have fun riding!

Proof an Italian can still talk with his hands even when they're full. Good to know it isn't all snake oil

PROJECT FARM did a really good comprehensive comparison video and it was amazing. Good info uncle tony!!!

I can't believe you're just learning this. I've used this every time I have a carb that's completely clogged. I put about a quarter of it in the tank with a full tank of gas. I let it sit for about a day then I start it with starting fluid to get it to run for a little then let it sit for another day. Throughout the week I start it and run it each day. By the end of the week it runs like a brand new motor. And, that's without ever pulling and cleaning the carb. I love this shit!

Chemtool B12 is my go to. '70's and '80's japanese bikes had to meet strict pollution standards, so idle and transition throttle are excessively lean.

Seafoam, Berryman's, and BG additive have all worked really well for me with my project cars over the years.

Two things I've found is 1. Seafoam is petrol based, so for a heavy cleaning I'll throw half a bottle in my sportsters tank. 2. If you are willing to give the rougher stuff a try like Berryman, renzol hyperfuel is definitely worth the money. By far the most immediate, feelable difference I've ever had with any of the fuel additives.

Been using it for years! I've bought a lot of cars out of back yards, before I even try to start them, two cans of Seafoam and a gallon of fresh gas, pull the coil wire, spin it a few times, almost always works..... Always enjoy ur vids!

I believe you're preclean helped it along immensely... it's a good cleaner, no doubt, but if those carbs need a rebuild, they just need a rebuild... just went through this with a Honda 4 wheeler... finally just pulled the carb & did a full rebuild, not one issue... I did run some Seafoam through it again after I rebuilt it, just for a little extra cleaning during the break in, but one of those jets was hopelessly clogged & wasn't having the Seafoam fix, so I just had to pull it... I am gonna start running some through my vehicles at least once a year though, because it does help when the issues aren't serious...

Welcome to the club Tony, it definitely works !!! I actually had good results with engine restore, two cans later.

I used to store my car over the winter. I always put Seafoam in the gas tank in the fall. Every spring, the car started right up and ran great. That stuff is great.

I'm rebuilding a 1971 Triumph T120R. It hasn't been started in 20 years. I take apart the carb because it had been converted to a Tr6 head and saw that there was a lot of dried up white powdery stuff in the bowl. I put some Sea foam in the bowl and could see that the powdery stuff was disappearing. So I put some in the gas tank and ran it for awhile. The longer it ran the better it got. This stuff really works.

You have, in my opinion, one of the best motorcycles ever made! I hope to be able to grab one some day in the not too distant future. Well done!

Used it on an old Harley years ago and it worked great. Last year a neighbor was having troubles with a little Chinese mini bike for his kids and I let him use my Seafoam. It worked for him as well.

My grandfather turned me onto seafoam a long time ago. Great stuff. I always keep a can around and treat my fuel occasionally just for upkeep. I've seen commercial injector cleaning machines use it as well.

I've been using it with great results for a while now. The most recent thing was I had a sbc that had sat on the floor in the garage for many years and new it was good when I pulled it for future consideration. Installed motor and couldn't get the lifters to pump up for love or money. Added a can of seafoam to the crankcase and I swear it didn't take 2 minutes for them to come back around. I put it in my tanks every oil change.

I've had major improvement after two tanks with Techron or Amsoil Performance Improver. It's good to know Seafoam works too.

I love and swear by seafoam in a variety of situations and I am surprised an old time mechanical mopar guru as yourself never knew of its wonderful properties. There is alot of bs out there people dont get me wrong but seafoam, liquid B-12 in the big can and pb blaster are necessary tricks of the trade imo, gotta have em

I've heard a good trick for unplugging carb is to get the engine reving then block the carb. The extreme suction can sometimes clear them out.

I haven't used Seafoam, but I used to use Gumout on my kid's dirt bikes (20 years ago). Fed it directly into the fuel line while the engine was running, it would run rough using 100% Gumout for fuel.... but after a few minutes all the passages on the inside of the carb would be cleaned out. Hook the fuel line back up to the petcock and it would be good to go.

Great stuff ! Marvel too . Great bike as well . I have been restoring bikes for over 30 years. Seafoam is good and is OK on gaskets.

I run a bit of seafoam in all my small engines throughout the year seems to help keep them clean over winter storage. Use non ethanol fuel as much as possible sure helps that too though... excellent videos sir.

I use Sea Foam in my 1997 Dodge Intrepid which I've had since 2010, it has 366,000 KMs (Canada).....I get great mileage and it runs smooth as silk. I haven't touched the plugs since I've owned it. I also add some Sea Foam a week or so prior to an oil change. I know the 3.3 L engine is very good but I really believe Sea Foam is part of my success....Thanks for your video.

Seafoam also pretty neat for helping keep intake runners/valves clean on direct injection engines. Pull some in w/ a vacuum line on the intake and let it soak a bit then run it out.

Both my dad and my father in law swear by Seafoam. Although they mostly use it as a fuel stabilizer (put it in the snow blower for the summer and the lawnmower for the winter etc.).

I first learned of Seafoam to "smoke" an engine, clean the inside. Worked excellent! I put a can in the tank everytime I take a trip to clean and lubricate the fuel system.

I've been using Sea Foam for years. It's really pretty good stuff. It also works in old flatheads (1947 Ford 8N) to free sticky valves when used in the crankcase and fuel supply. Sometimes, you just have to let it work, which may take a day or so.

Red Line Fuel cleaner actually has a tad more detergent. I had the same experience on a Suzuki DR200 that would barely start. Got it "running" and hobbled around the block three times to warm up the engine. Shutting down overnight let the heat soak into the carb which helps the detergent act on the "boogers." Next morning, ran like new.

Hey uncle tony. Sea foam is supposed to be an excellent fuel stabilizer for winter storage. I havent used any yett. But when winter comes im going to try seafoam. Ive heard very good reports from my friends. Also echo 2cycle pint in auto transmission really cleans valve body well. Improves sticky shifts. Bands etc.

I've been using Seafoam for years. Noticeable difference in my motorcycles, lawn mowers, and generators. Biggest change was on a Kawi that sat for more than a year with gas in the tank/carb.

While Derrick (VGG) uses Berryman's, it's similar stuff. He pours it right down the throat while running at a couple thousand rippums.

true believer here, regular seasonal use on my vehicles that dont see regular use, i used it once in the oil on a jeep 4.0l to free up a stuck lifter plunger that wasnt pumping oil to the rocker.

That's exactly what it's for! Personally I use it all the time when I don't want to remove my throttlebody or intake manifold to clean 'em properly on modern fuel injected systems (it's a hassle). I think of it as a basic quality cleaning, it's better than nothing! I've compared it after taking off my throttle and I can see it works for cleaning, not magic fixes like people advertise and expect. Also I've never noticed a difference for it cleaning the inside of the cylinder. I prefer to use it through the air intake as direct injection doesn't care if you put it in the gas. I use it mainly on modern Cars with direct injection after an oil change or if I notice stumbling and I'm feeling lazy. If you suspect it's just carbon or varnish buildup due to modern gas, it's always worth trying this $8 fix before taking stuff apart.

Have not tried Seafoam but have used Tech tron and find the stuff amazing. I have used that stuff in my cards and small engines ie: Snowblowers, powerwashers and it has worked great.

I also proved t to myself by using it on a skid loader that wasn't running very good. It had a terrible idle and almost stalled. I poured an entire can of Seafoam in it and let it idle for about 10 minutes and it clear up and ran perfect. It must have cleared some dirt out of the jets or small journals. I now use it in all my engines and also use it as a fuel stabilizer over the winter months in my lawn mowers and motorcycles. It works great!

back when i bought my truck a 92 chevy single cab long bed c1500 with the 4.3 v6, i drove the truck and it was fine then i put the seafoam in the gas then ran it all down and filled it back up and since then it has been running a bit better, it ran fine before but cleaning it with the seafoam i can feel the difference on how it runs. im just a young guy but my dad he told be to do the seafoam and im glad he did. even if i didnt notice any change i would have still been happy with it since its 30 years old, it would have given some form of peace of mind.

My 2014 Challenger R/T thru a code and was stumbling when I first started it , then drove normal at speed . My mechanic put Seafoam thru it saying there was a clogged injector . It now runs perfect and no more engine codes . I was amazed it actually does work .

I’m glad one of these additives actually does what it says…. Remember “slick 50” ?!? 🤣

Another one is Mr. Gasket Cataclean....... Just healed my 2002 BMW K1200RS from 20MPG to 43 MPG.....It cleans the Catalytic converters as well.....can't say enough about it. I use Seafoam in my Car too...Great stuff!!

I did the same thing for a lawn mower. It took 3 or 4 mowings and now it runs fine. One of the very few times being lazy worked out.

I had a 50,000 mile CB700SC that had heavy deposits on the intake valves causing low compression on a couple of cylinders. Fogged the intake until it stalled on a hot engine, let it cook for fifteen minutes or so and then ran it hard for some mosquito control. Repeat the process twice more and the compression numbers came back into spec. A lot of what is claimed by Seafoam is bull, but in this particular instance it actually worked really well.

Wow cant believe you have never used it before! It really does work! I have used it to get a stuck lifter freed. It took 4 or 5 oil changes but i have drove 100,000 miles since and it hasnt came back

I recently bought a similar fuel addative to help my scooter with it's bogging down, it stated that over applying won't damage my engine. I've noticed that that the valve noise is quieter and I have improved power output, I've since filled up the tank with fuel to run the product through thoroughly. I think those addatives help to clean the carby jet, they just take time. Like a few days. 👍

Been using it for years. Can be a lifesaver with old outboard motors.

By running a full tank thru and left overnight, it did as it was intended. I did it on my car and it worked perfectly. Buy doing it they way you did gives the product time to dissolve all the crud. Great video Tony.

Seafoam is also a good fuel preserver/stabilizer if your machine will be sitting unused for several months such as over the winter months. I have been using it for years in motorcycles, boats and lawn care equipment. I always have a few cans sitting in the shop!

I put sea foam in a 1952 ford 8N tractor and it worked wonders in the fuel tank so I put some in the crankcase and ran it for a few minutes and the motor smoothed right out. Changed the oil and it ran like a new tractor. Seafoam is great stuff!

I had a 99 Toyota Tacoma that had a stuck idle air control valve. It was a 4 ish hour job to replace and required pulling the intake manifold off. I pulled the vacuum line off the valve and put a funnel into it and fed it half a can of seafoam. It fixed the problem and saved me the trouble of doing all that work. Seafoam is magic in a can!

This stuff works! My 99 Silverado engine light came on, for catalytic converter. I added a whole can of this to about quarter tank of gas, ran it till almost empty. The light went off, I took it in for smog, and it passed with no issue. I might have got lucky, but the light is still off and its been almost two years now!

I have used Seafoam on all my small engines (outboard, garden tractor, lawn mower, weed wacker, etc.) for years and it has helped keep them all going with minimum service. It also has a fuel stabilizer in it so If I don't not use something for a few months and it will still start right up and run fine.

Works great for cleaning injectors and freeing up sticking valves. I haven't used it for much else. But it works for what I have used it for.

I love seafoam. I have a gallon can of it in my shop always. I like to use one of my paint guns to spray it directly into the intake while the engine is running. It cleans up direct injection system incredibly well.

I've heard about Seafoam for years. I'm old. All the anecdotal comments by others over the years and never heard anyone (I mean ANYONE) say anything bad about it. I tried using it about 20 years ago. No issues. What I learned, and has really made me a believer in it, is using it to fog small engines that I don't use regularly. Weed wackers, ice augers, chainsaws, 2 cycle, 4 cycle, etc. I drain the fuel tanks and put a little Seafoam in the tank, turn over the motor a few times to get the Seafoam into the carb. After a year or more of not using that engine, I can fill it with gas and it starts like I just used it 3 days ago. I'm a believer.

Several of my boating buddies swear by it in their fishing rigs. Pretty similar story, they decided to give it a try and it’s worked great

I've used it many times on old farm tractors that sit for long periods of time. Have to work them a bit for good results but it does work.

Been using Seafoam for years in all my vehicles, usually in the fuel tank at every 5K mile oil change interval. Gald to see Uncle Tony approves . . .

I've used seafoam to similar results, it's a mild cleaner that's not going to dislodge and clog up filters, jets or injectors and use it 2-3 times a year as fuel system maintenance in my clean cars and trucks. It can depend on whatever region you are in, but I cannot get high quality gasoline in my area, so fuel system cleaners are necessary every so often.

Seafoam and restore are 2 products that absolutely do work.

It’s a can of magic. Been my go to for 40 years after an old timer, like myself now, told me to try it on an old Mustang.

One of the things my Dad (He was an old school MOPAR mechanic) always used along with Marvel Mystery Oil! With the ethanol in gas today I put Seafoam in every tank of gas on my carburated engines and every other on my FI engines.

Seafoam fixed an intermittent miss on a Honda VTX 1800 I bought. I'd already done all the typical tune up items but it was EFI so no carbs to rebuild and injectors were not easy to get. After running out of options someone talked me into trying Seafoam. I gave it a heavy dose of half a can in the tank. Never had the miss again in three more years of riding it. I run some Seafoam through all my stuff a couple times a year now as preventative maintenance.

I had a gentleman with a 2007 Hyundai that would set check engine lights and poor idle. After multiple fixes he dumped a seafoam into the tank, it smoked for a few minutes, coughed and fixed itself. I was impressed. No idea how exactly it fixed it but damn if it didn't work!

I had an 82 GS1100GLZ...I loved that bike. Loved it. Also had a Kawasaki KLR 650 also, total love fest on the opposite end of the spectrum...

GS 550 L oh the memories that brings back. Thank you for the video sir! Carb tuning and balancing will be a lost art...😢

A few tablespoons of STP gas treatement or Gumout fuel injector cleaner will work as well. Seafoam can be added to the oil as well. But caution, it can loosen an otherwise tight fitting PCV hose, and cause it to pop right off while you are driving, thus spraying oil all over your engine compartment.

i have added an entire can of seafoam to 10 litres of 91 octane fuel , and ran it through my old craftsman snowblower , with in 30 minutes of using the snowblower , the surging and hesitation stopped , i continuously used the mixture , the engine ran like a top , 2 cranks of the starter and the engine fired right up ,even after 6 to 7 months of summer storage , it is also a fuel stabilizer

In Germany we use two stroke oil (add 1% to the fuel) for cleaning and preventing corrosion in ICE engines.

Had good results with Engine Restore. Both in 70’s made 318. Worked so well, was surprised most stores ( all around here ) stopped carrying.

I love this stuff. If a vehicle has been sitting for a month or two and is running a little rough I pour it in the gas tank and the problem is gone.

Italian tuneup: manually open the carb or throttle body (while running) and slowly pour the contents of one bottle of Sea Foam or B12 Chemtool into the intake. Cleans carbon from valves.

It works. I have seen Seafoam extend the life of more than one industrial engine when used as a crankcase additive (Caterpillar G398, G379). Frees sticking rings and valves. These were engines with 80k-100k hours. Hours, not miles. Takes a lot of Seafoam to treat a 50-gallon sump...

My dad has swore by sea foam for years. I also use it and have no complaints, though I’m skeptical of putting it in the crank case oil like it says you can do also. I run 91 octane non oxygenated with a dose of sea foam in all my 4 wheelers and dirt bikes and lawn mowers and all other small gas engines and I never have any problems with things starting after sitting for extended periods. I just pulled my garden tiller out of the shed after sitting for a year and it started on the second pull with last years gas even. I’m not a chemist just a poor country boy but it seems to me the stuff works 👍

I've owned multiple Suzuki GS's and belong to the GS resources fourm where many of the members swear by Seafoam. I believe in cleaning the carbs but I do use seafoam over the winter when I'm not riding. Cears for the video!

In 1967 my grandfather taught me to use Marvel Mystery Oil(MMO). We poured 1/2 of the pint can down the R1 on my Pontiac. I couldn't tell if it really ran better. Three years later I bought a 1964 Chevelle 300 2 door for $50, pulled the 6 cylinder engine and sold it for $25. I was given a 1963 Impala with a 283 but it didn't run. I replaced the timing chain and gears and found the cylinders to be very carboned up. I got the engine running and warmed up. I poured a pint of MMO down the R2 carb and shut it down. It smoked like a Uniroyal stack. I waited several days until it was raining and started the engine. I ran it a little above idle until it stopped smoking and then did a few revs. Pulled the car into the garage, pulled the heads, and found that the heads and piston tops were fairly clean. I overhauled the engine, put it in my Chevelle and had my G Stock drag racer for under $200. Over the years, I found that putting MMO in the gas of older cars tends to make the engines run better. I picked up an 89 Mini van with a weak compression cylinder. I tuned it and used it as my daily commuter. On construction site you really don't want to bring a nice vehicle. After 3 months on MMO in the gas with every fueling it was running better. At 6 months I did a compression check and all cylinders were good. I think that the MMO can get into the piston ring grooves and free up the rings that get stuck in carbon build up. I know that MMO helps prevent corrosion in small engine fuel systems but I'm not sure how much it helps automotive fuel systems. All of my engines are 20+ years old so, I use it in all of my gas. Its a wasted day if you don't learn something new. Good Luck, Rick

I've used seaform for everything. I had snowmobile that sat outside for 3 years. Injectors were clogged. Ran a clear tube on each injector and filled it with seafoam...set my compressor regulator to the fuel PSI, 9V battery to pulse the injectors open/closed and blasted seafoam through them at the same time. Ran like brand new after that.

I use it all the time as a preventive maintenance type deal on my small engines. I add a few ounce to a 5 gallon can everytime I fill it up. Ever since I started using it my small engine run like new. My 2 stroke leaf blower used to be a pain in the ass to start but after 1 or 2 fill ups of the treated gas they start with in 1 or 2 pulls. It used to take 10 or 15 trys before using seafoam. The aerosol cans work great also. I've used the aerosol cans on a few high mileage cars with great reault. I highly recommend it.

The shop told my sister in law that she needed a new throttle body. I sprayed a can of Seafoam into her intake as it idled. Been six months and it still starts and runs fine.

The best thing to do is vacuum some seafoam down a vacuum line. Techron does a better job of cleaning fuel systems. Techron is a high PEA cleaner, so you could use some other high PEA cleaner. Companies that specialize in racing engine make stuff just for carbs. It might outperform Seafoam or Berryman B12. After all, how many street driven carb engines are you going to encounter? It's a kind of specialty.

Over the years, I've bought 8 bikes that had been sitting for various lengths of time( several years on average). Buy a battery, drain old gas from tank (NOT the carbs) fill with fresh gas mixed with Berrymans B12 and 104+ octane booster. Crank until they start to run. Ride bike through 2 or more tanks of the same mixture. Results were that EVERY bike ran smooth, would idle and perform to expectations. Some were smaller twin cylinders some were 4 cylinders. All 4 stroke. The only one I pulled carbs on was a Suzuki GS450E to drill out the main jets. Inside was as good as new. NO further cleaning necessary. It had been sitting out behind someones house with a couple of small rugs on top of it for "weather protection". I wouldn't even change the plugs, just clean the tips with my plug cleaner. Sometimes I'd let it sit about 15 minutes between cranking, so as to not burn up starter.

Got a old tractor that had a cylinder down to 50 psi, thought it might be froze piston rings. So poured an once down s plug hole and bump it a couple times over the next couple hours. Tested it before I even started it and was up to76 psi, did it again. After the second time I was within 5 psi of the other cylinders. Its better fuel stabilizer than stable by a long ways.

I have used it for years , it's not a miracle worker but if your your fuel system is a bit sluggish yes . I put a cap or two in my tank every fill up ( honda vlx 600) . Runs like dream . Keeps it clean. Scotty says its bunk , and I know he is a very good mechanic. But I don't care it works.

I have a 67' mustang, Bought it 20 years ago and was a show winner. Gave it to a family member who helped me pay for an auto accident I had at the time. Car overheated and he parked it outside behind the garage for 11 years. Several years ago he called and told me come get it or it was going to the junk yard. Fixed the overheating issue (clogged radiator), new gas tank and a can of seafoam and it fired up and I could even drive it as is. I have a few short videos on my profile page of me getting the car running. I'm planning on a full drive through of it soon. I've been using that stuff for 20 years and can't say enough good about seafoam!

When I was in outdoor power eguipment business,30 yrs ago I was just out of high school,I was told to use Sta Bil….total disaster. An old dealer told me to use sea foam. Best fuel treatment I’ve ever seen.

One of the few cleaners (solvents) on the market that actually works. I've used it just over 40yrs - tried others but came right back to it. My cars - both diesel and gas - see it in the fuel system 4 times a year, my pickup the same, w/one can per oil change to keep the AFM free - so far 200k on my AFM 5.3 LS Silverado. When I had the shop I bought it by the case, used it to 'de-glue' all manner of carbs from snowmobiles to early 1900s motorcycles. It made a good way to decarbon the Aluminum heads on the All-Pro & NASCAR truck engines before jet washing. Does exactly what it claims - a rare product these days.

Put more than is recommended, and follow can instructions, spray into carbs until it chokes it out. Let it SIT for a day, then run through a tank of gas. It works.

My first bike was a 20 year old kawasaki 550 . Got from a friend. Spent cash on a shop cleaning the carbs but it still wasn't right. Kawasaki forum post suggested seafoam. And it work like a charm. Been using it since instead of Stabil over the winter and usually once a season . Works on Fuel injection too.

Been wrenching on motorcycles since I was a kid, worked in various shops throughout my years and will definitely tell you seafoam, Berrymanns and marvel mystery oil Do work in my experience provided the carbs are not in need of seals. I tell everyone who runs vintage bikes to put a couple ounces in every fill up and add marvel oil to the gas aswell as to the crank case.

Been using Sea Foam in my equipment, vehicles, and Harleys for decades. When you can't run the fuel system dry for storage add S/F and run the engine until you are sure that mixed fuel is in the system before storing.

A double strength dose of seafoam, techron, or lucas fuel system cleaner is standard practice for me after the bike has been sitting over the winter or similar situation. Obviously, the use of stabil or similar conditioner is a good idea when you know something will be sitting awhile, but sometimes that doesn't get done. My lawnmowers all get techron powersports continually, and they can sit all winter and fire right up, no surging or stumbles.

I've been told by a mechanic that he had a carburetor problem on a motorcycle that he had just purchase. He put some transmission fluid in the gas and said that the high detergent in the tranny fluid cleared out the carburetor.

On carbureted stuff seafoam is great. I like to drain the floats and fill the bowl with it, start it, rev it WOT and then choke it until it stalls. Let it sit like that over night. Drain and refill with gas.

Try "Gumout Regane" It's designed for use with gasoline that contains ethanol. The seafoam is mainly designed for 2 stroke engines and pure gas.

I had a Ducati Monster that wouldn't even start, used Startron Enzyme fuel Treatment, without even taking apart the carbs, started, idled and ran great!

Carb cleaners work by soaking & dissolving obstructions/blockages. A good way to clean a carb is with sort drives & park overnight then repeat. This gives the cleaning agent time to soak & desolve any dirt/crud & short trip driving will flush out & replace the cleaning agent so the process can repeat.

I'm able to get Xylene in the quart size in my area. I use it as fuel injector cleaner and octane boost for my VW 4 Banger.
