i dunno what it was. i did the seafoam trick. half a can in gas tank... half thru the vaccuum line.... and 1 bottle in the oil. ok its more than i should have done but i was desperate. seriously. smokes like hell but thats what it said it would do. smoke is dying down alot. if you havent used this stuff and your car or truck runs like poop i would almost be willing to buy you the 7 dollar can of this wonder liquid....
i know this sounds spamish but i am a true believer of this stuff now....
