    Has anyone ever used Sea Foam in their truck, and if so, was there any difference. Just went to Hilton Head last week in my wife's Ford Escape. On the way down from Michigan I was getting 25-26 mpg. Before I left Hilton Head, for home in Michigan, I threw in a can of Sea Foam, I was getting anywhere from 29-31 mpg

    If it worked that well, there would be none on the shelf

    I've found that Seafoam does not work well with diesel at all. OK for gas rigs, but never in a diesel.
