I own a 36 foot long cabin cruiser and carry 210 gallons of gas. My last boat was 40 feet long and held 250 gallons of gas. My neighbors all have boats of the same size so I have a lot of comparisons. Essentially the folks that do not use Sta-Bil have issues no matter how full they keep their tanks. Those who use Sta-Bil and keep their tanks full have very few issues. The folks like myself who use Sta-Bil and Star Tron have no issues no matter what the level of their tanks.
One of my neighbors who uses the fuel stabilizer and water treatment recommended by mercury had about 20 gallons of sludge and water in the bottom of his tank last year. I live in FL and it is humid all year long so your experience will vary depending on your humidity.
