I have a '92 Ford F-150 4.9L I6 with 135K on it. The idle was a little rough and the power was a little lack-luster, but that's really what I expected from a 13-year old truck. After a while, I started getting a knock that really impacted performance. The only way I could keep the knock at bay was to run 92 octane gas, which was really getting expensive. I went into the local auto parts store to look for some type of cleaner, when the employee said that Sea Foam would solve all my problems and told me that I could get my money back if it didn't. Very skeptical of his claims, I bought it anyhow to give it a try. With the engine hot I put the first 1/3 of the can into the large brake booster vacuum line slowly at first, then sucked as much in as quickly as possible until the engine stalled. I replaced the vacuum line and waited for about 15 minutes and started it up. It started a little hard at first being flooded with the Sea Foam, but while revving the gas, it soon ran very smooth and started to smoke like that old movie "Uncle Buck". I made an unbelievable smoke screen that literally shut down Beach Blvd on the MS Gulf Coast for about five minutes! The motor in the old Ford suddenly began to idle perfectly and throttle response was amazing. I then added 1/3 of the can to the oil fill hole in the valve cover and the rest in the gas tank (as instructed on the can). Within about 10 minutes all the lifters were silent and the motor ran as perfect and as powerful as it did the day that it rolled off the assembly line! I now run it on 87 octane gas with no knock whatsoever, so the savings at the pump has paid for the can of Sea Foam many times over. After cleaning all the carbon out of the motor with Sea Foam, the only thing that smokes now are the tires!

I have a 1999 Toyota Camry. I inherited the car from my father and it had a check engine light on when I got it. The light would come on and then go off, but it never stayed off long enough for the computer to reset. It was time to get the inspection done but it would not pass due to the light coming on. I took the car to two mechanics. They cleaned everything they could think of to make the light go off. Then one of the mechanics talked to another mechanic at the dealership. They replaced parts until I said ENOUGH! I had spent several hundred dollars on parts and labor. I still had the same problem.

I went to my local auto parts store and bought some Seafoam. When I got to the register the guy at the counter said, "That is really good stuff. Let me know how it works for ya." I thought, "yeah, right, he is just trying to sell the expensive stuff." I had already tried the cheaper fuel system cleaners.

I put a bottle of the stuff in the tank. By the time I had run 1/4 of a tank through the car the light was staying off for much longer than it ever had. By the time I had run 1/2 a tank through it the light went off and has not come back on in over 3 years.

This stuff is amazing!

I wish I had not told a, now former, co-worker about this product. He had an old diesel Mercedes sedan. The car was not running well, smoking, sputtering, etc. I looked at it and told him how to use the product to save the car. He took his time getting around to it and almost sold it to me for 300 dollars. I then asked him if he had used Seafoam yet. He told me no. Was going to sell the car to me in 2 weeks. He then asked me how to use it. I told him to buy 2 cans, replace the fuel filter (spin on type for diesels), and fill it with Seafoam then install. Then take the rest the rest of the first bottle and dump into fuel tank if empty go to fuel station and re-fill then add second bottle or if full already add the rest of the first bottle and then the whole second bottle.

He did that, it ran so well he would not sell it to me after that. He told me it ran better then when he had bought it. It also caused the gunk in his tank to free up and plug his fuel lines requiring a tank removal and cleaning. After that it ran like a champ.

I use it in motorcycles to avoid rebuilding the carburetor(s). I add one FULL can to the tank. Yes I know it's only a 5 gallon tank but it works.

I've seen it used on a VW Bug that had been sitting for a few (5?) years it was used to flush the carburetor and then in the fuel tank with fresh gasoline. It cleaned out the tank so fast that the fuel filter plugged up and stalled the car out on the side of the road on the first run.

I also use it to help flush an engine before an oil change, I use it to clean out carburetors when I do rebuild them, and thinking about using it for an 'on the fly' engine cleaning/smoke screen system.

I've used it to flush the stale oil out of a motorcycle it seems to have cleaned the clutch plates up and made them grab better but that might have been just in my mind.

It's not a cure-all but if you understand how to use it it works great.

This is the best fuel additive out there. Used regularly will keep fuel system clean and prolong the usefullness of present day fuels.
Have been using for about 10 years and swear by it.

Great product at an exceptional price. I use Sea Foam on my 2007 Vw Passat with turbo and have had exceptional results period.My regiment is one can in the gas tank with fill up for clean injectors and the correct number of onces 1.5 / quarts of oil directly in the oil between 30 to 50 miles before you change your oil & filter.

Do not add Sea Foam to you oil at operating temperature it sill evaporate and you get zero benefit. Add it to a cold engine and then drive between 30 to 50 miles and your engine will clean it self. Its a wonder product! I used in an old John Deer lawn tractor and it was fantastic !!!!
