had a buddy tell me this over the weekend...thought he was nuts but did some digging and look what I found....

I guess myth busters claim that this doesn't work but from what I have read they used too much....

Hey if it helps I am game

I have used fuel injector cleaner in my car and have noticed much improvement in milage ,just like the bottle claimed but only for that tankfull. The smell of the vapour from the bottle reminded me of a thinner based product. Could this be acetone ? Hmmmmmm ?
