How much Sea Foam should I add to a 60 gallon tank in a Chevrolet 454 7.4 V8? [SOLVED]

I have a class A motorhome with a 1994 Chevrolet 454 7.4 V8. With a 60 gallon gasoline tank, how much Sea Foam Motor Treatment should I add to the gas when I am not using it? Thank You.

Hi Zach,

Add 1 oz of Sea Foam Motor Treatment for each gallon of fuel in the tank to stabilize it during storage. If 60 gallons, add 60 ounces. If 16 gallons, add 16 ounces.
