Wal Mart gas is horrible. Believe it or don't.

Seafoam should not decrease your gas mileage, but you are supposed to put in a certain amount based on how much fuel is in your tank. Actually, you should put the right amount of fuel in your tank to match the 1/3 of a can the directions say to use.

From the way you talk about this experience, I would wager you didn't read/understand the directions. The brake booster is OK on most cars, which is what their website says, but on 99+ mustangs this only cleans half of your intake. You are better off using the vaccum that runs to the PCV valve, or the one that runs from the engine cover to the intake.

Do you stalk people at autozone buying seafoam, or what?

The amount of people who have had positive experiences with this stuff by simply following the directions makes it hard to believe you seeing 3 engines screwed up by it.
