I am a day sailor that uses very little fuel over the course of a season. Last season I used only 5 gal. At the end of the season I treated the fuel for winter. This year i have probably only used 1 or 2 gallons. As i start thinking about winter, should i: 1. Just leave it alone - does the protection wear out after a year?, 2. Treat the fuel again as if it were all fresh fuel- can you overtreat the fuel? 3. Sail to the Caribbean for the winter? 4. Something else?
