I've seen some Seafoam videos on youtube and they seem to work. Unfortunately, I'm just under the impression that it wouldn't work for me.(not with my luck). But, I'm still considering using it. A friend of mine used it on his 04GT and gave me a can that was about 1/2 full. He said it worked for him. I have a 99 cobra with 92k on the odo. If I were to use Seafoam successfully what should I expect?
