How much Sea Foam Motor Treatment should I put in my fuel tank [SOLVED]

Yesterday I put in 16oz of Sea Foam with about 6 gallons in the tank. It really helped!  Is it okay to put in another 16oz right away?

Great question Miguel. The answer is yes, go for it! Adding a higher concentration to fuel is safe and will increase the cleaning ability. Keep in mind that Sea Foam is made from gentle petroleum-based cleaning and lubricating oils.  It does NOT contain harsh detergents or chemicals.
