Now, I’ve run a lot of Seafoam through the fuel systems and intakes of a lot of cars, but that doesn’t mean I’ve read the label. Typically for my crown vic, I’d put 1/3-1/2 a can in a full tank of gas (with worth-while results) when it was time for that sort of ‘tune up’ - reading the label today though, it suggest mixing 1 oz per gallon of gas - that’s just over a whole can for a tank of gas in my car!

Does anyone actually use this at such a ratio? If so, does it work better than, say, a third of that?

As an aside, for storage I have some in the tank of the Chevelle which worked out to like 5 oz/gallon (oops) and it smokes and smells like seafoam when running now, in addition to unburned fuel and oil smoke.

(Also I recently discovered you can buy seafoam by the gallon, which is way more than I need but still tempting!)
