I put a can of Seafoam into my gas tank the other day, and then filled it up. The last couple days, my truck has hauled ASS. It's as if it's acting as an octane booster or something. I know it's petroleum based, but holy moly, whatever they put in it, my engine loves it.
Also, I noticed that it says you can pour a can into your crankcase oil as well. I assume this would be something you'd do a day or two before changing the oil, but it doesn't specify. I don't know if I'd want that strong of a cleaner going through my crankcase for the whole duration of time between oil changes.
