2 bottles of Sea Foam [SOLVED] Asked by Antonio P. In Texas What happens if I pour two bottles of Sea Foam instead of just one into a full tank (35 gallons) of gasoline?
Hi Antonio. Adding two cans to 35 gallons of fuel is fine, but you’re only adding less than one ounce per gallon. Here’s a tip: I always add Sea Foam when the tank is low to increase the cleaning concentration. I might add 2 cans to 1/8th tank and drive 20 miles before adding more fuel. Hope this makes sense!
