I have a 2009 Dauntless (75 gallon tank) and recently had to replace the fuel float. I probably only burn about 50 gallons a year and am concerned about the "old fuel" in the tank. Does anyone know how often you should clean the gas tank to remove old fuel that could damage your engine?
If you have a filter with a water separator you shouldn't have to worry too much because the filter will tell you if you have water in the fuel. As far as using fuel with ethanol, I wouldn't do it to save a couple of dollars. Buy your fuel at a marina so you don't have to worry about ethanol problems. If you ever have an ethanol related fuel problem it will probably cost more than the few bucks you save, not to mention the aggravation.
I winter in Ft. Myers and summer in St. Joseph, Michigan. It’s now about 12 years since I’ve joined this group. I gave my 1972 whaler to my daughter and sold the 17’. Bought an O’Day 28 sailboat and sailed on Lake Michigan. Yesterday I bought a 2005 130 Sport.
I've never emptied mine out - going on 30 years. My fuel/water separator has always done the trick along with a little fuel stabilizer. Some here may find that neglectful :)
