this works extremely well on my '91 Chevy K1500 especially during the winter months. Cleans up the engine works and smooths out the idle. Using this I don't have to worry about using dry gas.

I add 2 capfuls per half gallon for regular treatment. 2-4x that for treating an obvious problem.

I put in a older Mercedes and forgot about it, sometime later I took it for a drive. It ran like some one just turned it up.

I have a 2010 car with a little knock and I use Sea-Form in my car so that it will run a little better and quite that knock. Buy some today.

Using the same tank of gas in the process to confirm it worked, it made the difference. Problem starting has been cured ever since.

I tried several brands in my vehicle. This one has performed better than most of them. A whole case of gumout didn't even do what one single bottle of seafoam did.

Was having some trouble starting up my car every once in a while. Instead of aiming higher for a starter or alternator, I started with this and im glad I did. My car starts up great now

Used as a fuel treatment and to get an old Jeep back to running. Worked as intended.

The straw barely inserts into the spray nozzle and blew out several times during the application. PLEASE FIX THIS! I will not buy this again unless they change the nozzle/straw applicator.

I have used Seafoam for over 20 years. It works. It is very strong and cleans your entire car engine out. It is powerful and increases your gas mileage especially in my older car. I am getting 3 more MPG with this product. I use it every 6-12 months since I do not drive much. I drive less than 2,000 miles a year but still use this product once a year right after my oil change. It works that is my take on it.
