The gas tank on my new-to-me boat is full. 80 gallons. Nobody knows how old it is. At least older than one year. That's a lot of gas to 1) replace 2) figure out how to get rid of. Is there an additive that I should use? I'm probably more worried about gumming up EFI and other damage than anything else.
