I don't put the stuff in my gas, because it's more likely to wash gunk through the fuel filter where it'll lodge in the injectors than it is to do anything else. AFTER replacing a fuel filter, I might consider a fuel injector cleaner. Most cars, most of the time--if the intake is dirty I'll clean it with carb cleaner (spray acetone) long before I'd consider sea foam, just because a spray can is easier--and it has the same benefits of cleaning intake valves and such.
I am also a fan of ATF as an oil flush, not worried about its effect on gaskets because it doesn't hurt transmission gaskets. I'd use it to unstick rings as well.

seafoam isn't any thinner than fuel, no... but fuel is naturally has it's own detergents (ever spilled gas on the floor and wiped it up?).... and if you run fuel rich enough it will get past your rings and thin your oil out... possibly causing a BHG or a spun bearing.....
