It pains me to say this: I have almost 280 gallons of gasoline, 140G in each of two tanks, on my boat that is approaching five years old. The real pain comes from not having used the boat very much (not at all) in that time. At the time it was topped off I added more than the recommended amount of Stabil to the tanks. It was mixed well. I plan to use the boat this year. How can I make sure that it's useable and safe for the engines? Would it have lost it's 'octane' in that time? Can I add octane booster? Not a fan of replacing 280G's of gasoline just-in-case. Would like to be sure first. Any suggestions or recommendations?
