Nothing better in my opinion
I have 1968 dated 426 cu. in. dual quad hemi. I use Sea Foam to overwinter and during the cruising season to keep those carb clean and running smooth. I also use Sea foam in my two stroke motors and all other engines. Especially those that are not ran regularly.

Doing what's needed
It does work as far as cleaning the upper intake and heads I think. It blows out a serious cloud and did bring traffic to a dead stop behind me. lol. But I still can't get it to pass the smog test in CA. I've put 8 cans into the top of the motor.(Tip: buy the pour cans, not the spay. There's never enough pressure in the cans to use everything in the can. I hate wasting money.) I pulled a pcv hose off and put a rubber adapter with a hole the same size as the spay bottle tube. Then stick the tube into the pour can and it will suck out 100% of every can. Plus the pour cans are cheaper.

    excellent stuff
    I've had 9 Porsches over the past 30 years. Putting over two million miles on the lot of them. My present 911 has 491,000 miles on it. SeaFoam has been used constantly. I have never had an injector problem on any of my cars to date. The cost of gas, lately, has caused me to do less driving, which hurts a retired guy, that drives daily! I'm not an engineer, chemist, or a auto repair guy, but this stuff works!

    Dirty Fuel Injectors on my H-D
    I have a 2006 Harley-Davidson Dyna Wide Glide, about two years ago I had it in the shop due to it at times only running on one cylinder, the mechanic stated that they rode it several times and it ran flawlessly, but I didn't go five miles and it started running on one cylinder, needless to say I was not a happy camper, but I thought, Murphy's Law. So I pulled into an auto parts store and purchased a can of Sea Foam gas treatment and poured in about half a bottle, now mind you for the most part I normally use 100% non ethanol gas when I can find it while out on the road. It took a while and I felt that it sitting with this product in the fuel injectors would be of benefit, and it was. On my next tank of gas I put in the rest of the bottle and over time it seemed to run better, now its been two years and I put in about half a bottle at every other fill up and it now runs like the day I bought it and it seems to have more power.

    My Goldwing loves it!
    I use this religiously in my 2008 Goldwing. 500 miles before every oil change I put 4 oz in the oil and then 250 miles before I add 7 the rest to the gas to the last tank of gas. My bike runs so good at 107,000 I now use it in ALL my vehicles including my 69 Camaro convertible show car. Proper maintenance will keep them running twice as long!

    Best product I've ever seen and I haven't had any problems since I started using it several years ago
    Starting outboard engines, smooth operation, dependable. I haven't worried about "engine" troubles for many years thanks to Sea Foam. I used to fish BASS tournaments for 30+ years and You can't afford to have engine problems when there's so much money involved. The last few years I was the head of ramp security on the lake where I currently live and I've suggested this product to everyone on the lake. Many of them use it now. Thank you

    The best motor treatment money can buy!!
    Sea Foam is my go to for cleaning my fuel systems in my 25 Ford T bucket, 1999 Mustang GT, and my 2013 Dodge Minivan. I also add it to my oil just before my oil change. The performance of the product is stellar. I highly recommend it to all my family, friends and strangers!!

    I run it in all my rugs. Keeps the injectors clean. Keeps the carburetor jets clean in my boat, along with stabilizing the fuel for storage. I've been useing seafoam for many many years!! I swear by it!!! I wish you made one for use in 2-stroke engines.

    I buy it by the gallon and use it in my truck, boat, pressure washer and lawnmower!
    I initially started using Seafoam after buying an older Carbureted boat engine, that was running very rough on 3 year old low grade gasoline after having sat a while, I couldn't syphon the old gas out due to anti syphon valves in the filler tube. I put in about 10 oz of Seafoam per Gallon in the tank and then started the engine, it finally started and smoked quite a bit due to all the varnish burning up. I then ran the too engine cleaner through the carburetor, the engine went from barely running and stalling to running smoothly and with power.

    The real deal!
    You know, I started using this additive in all my engines after Al Linder recommended using it on his fishing show about 10 years ago. I said to myself Ron's a Christian and if he says it's good and that I should use it, then I believe it. I have never had an injector, fuel filter, or plug foul out on me in 10 years. Coincidence? maybe, but I believe that it does exactly what it says it does. I will continue to be faithful and use this till I find out otherwise. Keep up the great work, and please don't change a thing. Faithful in Oregon, Joseph

    You wont be sorry
    Wait for Empty gas light to come on, add it to your tank, drive around block to mix it, let it sit overnight, AM fill up. I do this every 4-5 tanks. Own two 97 4runners, the baby has 185k, the other 307k. Never a problem with anything in fuel system. Both run like new, just do your regular maint and this and your set.

    Stopped engine dieseling
    I am so amazed with SeaFoam Motor Treatment. My 1985 Nissan/Datsun 720 had an abrasive engine run-on after turning the key off (dieseling). A bottle of SeaFoam in the tank and a bottle sprayed down the carb throat and the problem is a thing of the past! Cleaned out all the gunk in the motor and it's running better than it has in 20 years!

    Beyond ALL Expectations!
    I used it on my Yard Machines 3.5HP Gas Lawn Edger, that was out of commission (wouldn't turn on) for over 3 years. I added it to the fuel, I cranked it up and it started on the first attempt but turned off soon after. I pumped some more fuel and cranked it up a second time and worked like a charm! Thanks for a such a great multi-use product, now trying this on my Hyundai Santa Fe.

    Sea Foam really works.
    My truck sat for 6 months while I had back surgery. When I went to start it the results were not good. I added a can of Sea Foam to the gas tank and started to drive on the Freeway. It was rough going for about 8 miles. Then the engine started to smooth out. Halfway back it was running perfect. I have been using it ever since.
