I recently bought a truck that had a rough rough life. I never used Sea Foam before but a friend recommended it so I tried it. I will never use anything else again !! The engine doesn’t knock anymore and after putting it in the fuel the mileage has gone up as well. Couldn’t ask for anything better !!

My check engine light would come on and stay on in my 2003 Altima. I took the car to a local garage I trusted, they said it would cost about $ 1700.00 to fix. Since this was an 16 year old car not worth spending that kind of money, I tried a can of Sea Foam. After driving some the light went out. This occurred several times and each time the Sea Foam did the trick.

as the lead equipment mechanic for street and sewer maintainance of a major midwestern city, anytime we had any problems starting a two or four stroke engine, we automatically added seafoam and let it sit for a few hours or overnight to clean up the fuel system. this treatment was almost always effective. with todays fuel problems with sitting and storage,seafoam works like an extra mechanic eliminating varnish and making startup a breeze.I carry seafoam where ever I go.
