How much Sea Foam can I use in fuel? [SOLVED]

Can you use too much Sea Foam in one tank of fuel? I used one can in an eight gallon gas tank. My car is a ‘08 smart car 3 cylinder.

Hi Larry. You cannot add too much Sea Foam to car fuel, so adding one can to 8 gallons of fuel would not cause any concern. In fact, you could add a full can to 1 gallon of fuel if needed. Hope this helps!
