your measuring weight ounces which is different than fluid ounces.

A couple months after doing the intake valve cleaner process, I took my truck with 178,000 miles in to get its annual emission test. The mechanic told me he never seen a truck with so many miles have such good emission test results. I use seafoam in the fuel tank, in the crankcase oil, as a intake valve cleaner, and in all my lawn equipment. I have a 1998 Lawn Boy FWD that uses Seafoam and its still running strong. I depend on that lite weight mower to cut my steep lawn, I'm 75.

Be super careful. At about 2:50 he shows spraying Seafoam directly into the intake, the red plastic spray straw can easily be pulled right off with that suction and you dont want that being sucked into a valve. You dont need the straw down the throat of the intake, anywhere close and its all going in, an engine is the strongest vacuum machine on the planet. Otherwise perfect stuff.

Great video. Professional and on point. Nothing worse than having people tell jokes and ramble on. Thank you.

Sea foam is one of the longest running brands in North America. Ive been an Automotive repair Tech for more than 30 years and I have used Sea Foam countless times on customers vehicles with fantastic results. If you are on the fence about putting this in your vehicle , no worries at all. It's totally safe if used correctly as outlined in this video. Great video by the way !!

I'm a mechanic and the sea foam company came by my shop and poured water in my gas tank and I started the truck up and it started popping up then he put a can in my gas tank and then we went to lunch in the company truck and when we got back we started up my truck and it ran great no problems with the truck it desolved the water and raised the octane and it ran like it had nitrous in it

I refer to SeaFoam as magic juice. First time i used it was on a jeep with frozen fuel lines. I added a full can to the tank, and within 10 minutes, the seafoam had worked its way through and attacked the ice. It attacks water too, so its an excellent stabilizer. I use it in every engine I own!

Friend of mine has a 2003 f250 6.0l diesel with around 450,000 miles on it. He always puts seafoam in the crankcase for the last 1,000 miles before an oil change. You would not believe how clean the top of the heads are! They look brand new, it's wild!

I've been using seafoam 4 years--I'm convinced it treats fuel ⛽️ really well--all my small engines 2&4strokes start and run like new--great product!!

If you're like me and only buy high milage cars, this is essential for them to continue to run for years to come afterwards. every oil change one can of sea foam, half in the engine, the rest in the fuel. run the engine for about 50 miles, and drain the oil. This will flush out any carbon in the engine, and begin to clean it up. Once you start to do this, your engine will run better and better as time goes by. Lifters may clatter at start up, but will quickly pump up and quiet down. it you do this every time to service your engine, it will get better and better. It also works with transmissions!

As a car guy I've used Seafoam for decades in every car I've owned. What even cooler about it is that it's great to use in Coleman lanterns and stoves to both clean the generators AND stabilize the white gas (or gasoline) fuel in between uses.

My dad ran seafoam through the powerbooster vacuum line. That way you didn't have to disassemble the intake. Works great, keep it running if you do this, don't let it die while treating through vacuum line 🎉

A friend of mine that happens to be an engineer and owner of a company that sells his products in Jegs and Summit is a firm believer in Seafoam. He turned me on to it, and it's a great product !

Liquid ounces should be measured with a measuring cup. Ounces measured by weight are different than liquid ounces. Probably not a big deal as I usually go heavy on whatever dosage they recommend and add it about 500 miles before I change the oil. Just make sure you don't overfill the crankcase. Use a good quality oil filter once you change your oil. A good quality air filter changed regularly is also a must. I run a high mileage full synthetic oil rated for 20k miles and change it every 10k. I also add an oil stabilizer with every other oil change. I do the crankcase treatment about every 40k on the cycle when I haven't added the stabilizer, and add fuel treatment/injector cleaner when I do the crankcase treatment. My last vehicle had over 300k miles on it before I "retired" her. When I last changed the timing chain and replaced the valve cover and oil pan gaskets, the engine looked super clean inside. I would've kept driving her but unfortunately, the manufacturers don't build the stuff attached to the chassis (interior, plastic components etc) to last more than about 12 years before it all starts to fall apart.

Fluid ounces and dry ounces are different. Fluid ounces measures volume where ounces measures weight.

Dude, thank you for the awesome, thorough and coherent video! Great job explaining and taking proper video footage step-by-step!

There's a general rule also that the more smoke there is the more gummed up and dirty the motor is the less smoke the cleaner the motor I've been using seafoam since the 80s when I was a teenager always have trusted that product

Sea foam has brought so many engines back to life for me. I recently decided to dump a little in my weed whacker and was shocked at how much it improved. I thought it was good anyway but man was I wrong. Cleans my mower up after winter every year. Thinking of doing all this to my plow truck next weekend

went from 15.3mpg to 19.6 mpg in my 2006 suburban with 196,000 on it. only had to fill up once driving from Detroit to northern Minnesota.

I use Seafoam in every internal combination engine I own. My 02 Silverado has 289,000 miles on it and it gets Seafoam in the tank and crankcase every oil change. I buy it by the case. The i side of my engine is spotless. A few yrs back I changed valve cover gaskets and there was 0 sludge of any kind built up in my motor. I couldn't believe how clean it was. Keep making the good stuff Seafoam!!👍😎

My preference is the lucas upper cylinder lube and injector cleaner stuff. Makes a massive difference in my car vs other brands. Supposed to get 29ish highway on my 09 impala with it and a 1600 mile trip we got 34. Prior we got 24. It goes down to about 20/21 run a medium sized bottle and it jumps back up. Then trickles back down. Seafoam did work very well on my outlook. Had picked up from a buy here pay here and it had been sitting a while. 2 cans in gas and one in oil plus a spray blend of it into the intake and it smoked out our neighborhood and down the road about a half mile. Ran pretty good after.

I've been using this stuff for years in my '86 Toyota Van with EFI, usually 1 can in the tank about every 3rd or 4th fill up, so about 1000 - 1200 miles, and it keeps the injectors in great shape. The engine is pushing 190,000 miles now, and still starts and runs great and consistently gets 24-28 mpg. (not bad for a little 2.2 liter engine dragging a 3450 lb. van around!). Seafoam is one of the very few 'fix-it-in-a-can' solutions, that actually does what it says!😉👍

I USE SEAFOAM AND NOTICED THAT MY OIL GOT DIRTY REALLY FAST. GOOD STUFF.!!!!

I used to do small package delivery with a couple of Prius. The older one about a year ago started to develop a timing chain rattle which I knew would be either a worn/stretched chain or a gummed up timing chain tensioner. I started adding sea foam to the oil at each change after about three changes the timing chain rattle is gone and the engine runs as smooth as silk. That car now has 490,000 miles on it. I recently started it after sitting in my garage not running for 10 months, it fired right up with none of the shuddering and shaking you get in a Prius that hasn't run for a while. Scotty Kilmer says it's crap so that's a good enough reason to me to use it.

I have had this stuff unstick lifters on an engine with 230000 miles and later on when we rebuilt the engine it was so clean inside. I would recommend doing everything he done in this video at the same time. This stuff works great.

Good stuff. I have been using Seafoam for years. Love it. Good vid, thanks for the info!

Seafoam cleared out the rough idle from my motorcycle that was laid up for over a year. Good stuff.

Appreciate you your video was very informative and I’ve been using seafoam for years and it works

Thank you!!! Being one of those ladies who changes her own oil, I found this very easy to do and feel good about being able to do this myself!!!

Bought a 05 Tacoma and it felt a little sluggish and would vibrate a little. Ran seafoam in my tank for approx two months straight and the truck runs like new. This is by far the best fuel treatment out there. I hear Lucas brand is a close second, but based on my experience, I’ll be a lifetime customer of seafoam. Not the cheapest but quality stuff.

I can't stand when some people explain stuff terribly but you're to the point and sweet you explained real good good job

I have used seafoam in probably over 20 vehicles and never once has a problem. I had an old 05 silverado, 4.8 with 400k miles. Put a whole can in the engine oil, ( was gonna change the oil the next day ) and forgot it in there for a month. Changed my oil and the oil was so dark and had so much crap in it. Put a can in the fuel tank and filled the oil back up and man it ran so much smoother and had noticeably more power. Me and my roomate did the 3 seafoam treatment on his 500k mile f-150 and it ran quite a bit better. Still purring along years later. They recommend measuring out in oz to how much fuel you have in the tank. I literally just dump a whole can in with 3/4 of a tank of fuel and drive it a bit hard. Have never had any knocking, pinging, detonation. nothing. Just smoother and better running after.

Good stuff! especially for some of the newer cars with GDI engines.

Awesome, My bro just got me on to this last week! He's been doing it for years on all his rigs. No measuring needed, one in the gas, one in the crankcase good to go! That was on my 98 Expedition. He does his Land cruiser, BMW, GM. I've seriously already noticed a difference.

Dafuq ... ?? I took the short bus to skool , but even I know liquid ounces are different then solid ounces in weight. Cant believe this guy is pimping us this hard. And hes good at it. Ill watch more of his vids , now, to see how he pimps us next. !! Respect from the coats of Maine. y'all !!

I have always used it for keeping the fuel system clean and in the off season for a fuel stabilizer. For probably 25 or more years I never needed to clean my carbs because it keeps them free of dirt and varnish. I swear by it for those reasons alone. I have used it before oil changes also to clean the engine out good.

many thanks for the explanation on that system sounds like a winner to me!!

Ive been a powersports mechanic for a few years now and this stuff works wonders on air cooled single and twin cylinder engines. Ive never been brave enough to use it on road vehicles due to potential exhaust deposits. I just use lucas oil instead

Rosie O'Donnell gargles Seafoam every morning.

Nice looking ride. Going try this out on my 1996 OBS 5.8L 187K, it runs good now.

Works great on my diesel 73 idles great

Kept getting misfire on my mustang V6 2014 . This clear it up

7.5 liquid ounces is different than 7.5 ounces of weight. Fluid ounce is a unit of volume, so it must be measured in a container of known volume e.g. a measuring cup. Dry ounce is a measure of weight, so it must be measured using a balance or scale.

It really works well. been using it for years now on all my cars. Trans am was losing power especially top end, 1 intake clean up power restored. Cleaned it twice, my other cars only once but I add it to oil and gas tank approximately every 5k miles. They run nice and smooth:)

Yes. Awesome, thorough video! Great job 👏

I use this stuff in my car to .. I pour 1 can in the tank, 4ozs in the motor oil, about 500miles before a oil change. Sea foam works great.

I've used this product for years and didn't know you could put it the Block , Thanks

Great video very educational I'm going to try this application on my 2006 Town and country that I just purchased and hopefully I'm going to get good results thanks again for this wonderful video

Been using on my 1992 outboard motor every year ..Still fishin ! Works great. Engine starts every time. Good for winterizing (fogging) too.

Sea Foam has been a wonder on smaller engines too. My old Gravely lawn mower was running rough even after replacing filters and giving a new plug. I used it on the intake and fuel and now it runs like it's 20 years newer. Also, you can use way more than what the bottle says on a small engine and it won't hurt it.

The absolute best thing you can do for your high mileage Windsor is to replace the timing chain and sprockets, regardless of how well it runs. You need to dial in that valve timing for optimum performance. I drove my Ford 302 70 miles and shut it off. It was running perfectly. When I tried to restart it, all it did was backfire. Had to get towed and have the timing chain replaced. Do this before it screws you.

I used seafoam direct into the catalyst converter clean out the carbon ran it for about 200 hundred miles and it worked my car passed inspection

Thank you for the awesome tips this is going to be the first time I used this , but I’m gonna use it today thanks again

Great content 👌 👏 👍 😌 everything on point

Seafoam is Great....used to use that wayyyyy back and was very satisfied with it!! We also used to use Marvel Mystery Oil for our carburetored older cars an trucks! 😁 Miss the Old Days! ❤️ when we could do our own work on our vehicles!!

I'm glad I came across your video it helped me alot. Thanks I was worry doing it on my ford truck.

You are awesome!! Thank you for a definitely useful video. I jus bought it and now thanks to your help I will be putting it on my Chevy van😊

Nice video, I got a kick out of the scale too! I had no idea about the intake use. My neighbors will love seeing the smoke!

I bet the neighbors love that! I usually go out in the country and do this,then take it on the interstate but not in high gear. Then change the oil. Haven't tried it in the crank case yet. Not so sure about that yet!

Thanks. Going to try this on my 2009 Honda Fit. Has 200K miles. Super dependable car.

On my gasoline engines been using for decades. It's dollar tree fuel treatment for me. Price now $1.25 at Dollar tree. Red cheap heat diesel fuel treatment about $2.26 a bottle at Walmart and most places. And the best fuel of all is propane no fuel treatment needed and way less maintenance than any other engine running propane. I can store propane for years and the engines fire up first time on propane. In cold winter on my gasoline engines I use propane to help start the gasoline engine up in winter so it won't kill the battery and for a fast start. I do this on the gasoline engines I haven't converted over to propane.

I've ran it though fuel, I take, oil, and even the vacuum lines and to date no issue's from it, I straight up stand by Seafoam

Thanks for showing how much smoke comes out after the hot soak. When ever I do a side job tune-up I use Seafoam. The clouds of smoke can be alarming to the customer, so it's nice to be able to show them what will happen during the Seafoam process. I feed my Seaform into the engine via the vacuum line of the brake booster. I get 8-12 ounces into the engine before the smoke begins. I shut off engine and let it sit for 30 minutes then take the vehicle out for a quick spin and burn / blow out all the smoke and carbon. I then proceeded with a full tune replacing cap, rotor, wires, plugs, fuel and air filters. Customer's love the tune-up but the excessive smoke freaks them out. all t

Well done. Thanks. Going to use the information in this video o my 2019 Chevy Spark (20400+ miles)

We use Seafoam in our Fire Apparatus, Great stuff, have not seen the aerosol clean but thank you we will look for it.

After it soaks your supposed to take it on a spirited drive.

It also improves the seal of the rubber seals inside your oil and fuel systems!

Thanks brother I used it on a 2010mini cooper and is running amazing 👍🏽

Very informative well made video. Thank you.

I have been using seafoam products since the early 90s. It is an excellent product. I've used it too stabilize fuel, clean varnish out of carburetors, and carbon out of combustion chambers on vehicles and lawn and garden equipment. I love it.

I use it in my Mercedes glk350. My mileage was around 15-16 miles per gallon. Now I'm getting an average of 19 mpg, so it's definitely worth it to me. I pour one of the fuel injector cleaners into my tank twice per week.

Was a motorcycle shop by my old store. Bugged the guy for months to help with some carb issues I had. He said 90% of his carbs would clean and run perfect after using seafoam. Thought he was messing with me. Worked so well after one tank. I have now been using it ever since. In oil, fuel, snow blowers cleaning. Best stabilizer as well. It is truly the most magical vehicle product out there.

Love the truck man.. thanks for the good guided info also.

I've used high mileage sea foam and works great but I really love using the Lucas brand as well and they're products tend to work smooth as silk in my 1994 K1500 !!!

Ya I have been using these products in gas tank and throttle for some time now Love it

Awesome video - thanks man!

I have a Buick with 230K miles, trany start jorkin on 2nd Geer, SF fix problems for $10. No trany removal , neither dropping oil pan. Apparently fantastic product .

Nice video, BUT, you should've used a measuring cup for the crankcase application....not a scale! Liquid ounces are different than "weighted" ounces.

I have been using Seafoam for the past 5 years on a 2000 Chevy Express van 4.3 v6 with 190k miles. I only use because 1 lifter doesn't fully pump up it really taps loud, and after adding 2 ounces of Seafoam the lifter pumps up & is completely silent. The engine runs perfect until the next oil change. Can't recommend this product enough, it has saved me thousands $$ 👍

Every spring I run 15ml per L of fuel in my 1978 KZ650 B2. It improves every aspect of the fuel system y the end of the tank. Wonderful if used per the directions. P.S. I'm sure your neighbour's love you.

This specific video definitely convinced myself that the SEAFOAM treatment is helpful and not harmful. The logical explanation of truthfulness has finally found me 🤣🤣🤣SFFTW🚀🚀🚀🚀

I have been using this in my lawn equipment for 10yrs +. It works most 96% of the time on slow starting issues. All the time when I used it as a year end fuel stabilizer. Some of my trimmers & blowers may not get touched for 2yrs. Fires right up within 6 pulls. My 10hp generator had 5 gallons of 2019 reg gas. Bi-yearly test runs since, 1st pull.

Been using seafoam as a fuel treatment for my '37 chevy firetruck for 12 years.starts everytime.helps pickle the fuel

Seafood worked excellent on my moped and I followed up with your method my moped works much better in acceleration and quiet down the grunge sound cleaned up the fuel injecter very well I used 4 ounces of seafood added to gas tank and I also followed up withe the spray treatment with the stability arson spray into my intake manifold and carberator

Just putting this out there he said add to every tank of gas bottle say every “3000” miles for best results and to only run In oil 100-300 can clean to much and blow ‘em but great video man!!

When you're down to around a quarter tank of fuel, you want to add your Sea Foam and then top your fuel tank off.

Would it affect your catalytic converter?

Thanks a lot I have a 1988 Ford f150 5.0 that will help me keep it up and running

I use it all the time. It's a great product. I had several service lights on and after using seafoam the service lights are out.

I think they were talking about liquid ounces per quart of oil rather than "weight" ounces, which is what you measured with the scale. Probably not too far off, though, so not a big deal. Thanks for doing this one! :)

Thanks! Very good video. Informative. etc.

Awesome video! Did you notice a difference from the first treatment? If so, where did you notice the most difference?

Don’t leave seafoam in your engine oil it’s a heavy detergent and can break it down just follow the directions and change your oil after 300

Overall, thoroughly done. Thanks.

Seafoam is an amazing product. I have used it for years on all of my vehicles

Cool cool bro. Always wondered bout that foam. Curious to try on my 2000 safari.

Wasn't the crankcase amount supposed to be measured by volume rather than weight?

I do the "hot soak" use the same bottle for crank case . Get engine warm then pull break booster hose pour sea foam in that it sucks it right in. Let it sit for 30 mins then start it up. I do it about once a year on all my vehicles . Since I'm the one who does maintenance on all my personal and work trucks. Basically the same as this video but without the special can with hose.

yeah, I noticed the same thing as the comment below. Be sure to measure fluid oz with a measuring cup instead of weight like in the video

Fluid ounces and weight ounces are different measurements one measures volume the other measures weight. Different liquids (substances) have different weights per unit of volume so using them interchangeably is inaccurate.
