We sell a TON of Seafoam at Advance Auto Parts, where I work. That and the Lucas oil stabilizer and small bottles of Lucas fuel treatment. Most of the time for a carbed car, pour Seafoam straight down the carb back and forth between left and right sides on the primarys. On Fuel Injected, most of the time you take the vaccuum line off of the PCV and suck it into the intake manifold through it.

The time period for sitting will give the most effective carbon breakdown without the Seafoam evaporating as stated in an earlier post. People use it in cars, lawnmowers, small engine (weedeaters and such), motorcycles and boats. Most don't talk about adding it to oil, but adding to gas and sucking down a vaccuum line is the most effective way to use it.

Unless you know what you are doing, NEVER pour water into the intake or you will Hydrolock your engine and kiss it goodbye forever. I believe our current price for Seafoam is $5.44 a can, and we sell it like crazy. And like stated above, if sucked in and let sit, it will smoke like your car is on fire, but this is normal, lol.
