how much is too much

[texasrices]

I put one full can of Seafoam in a full tank about every three to four thousand miles. Is there such a thing as too much or too often when it comes to using Seafoam. For example...would it be alright to use maybe half a can every fill up???

Using that much Seafoam will not hurt anything but the spark plugs, and gas mileage.

I just add a couple of ounces at each fill as recommended on the can.

Couple of ounces every other fill-up would be plenty to mantain once you got the system clean. I don't even use that much if it is running right. Just a splash when I think of it every 3rd or 4th tank.
