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.

    Exceptional Motor Treatment
    I have been using Sea Foam for many years and can say first hand that this treatment is excellent. I use it in both of my vehicles and my boat ! It has saved me in not having repair bills as well as saving me alot on fuel ⛽️

    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!!

    Nothing Better!!
    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.
