I'm in north florida and get out on the water at least every other weekend, often more. How worried should I be about phase separation? The tank is only 15 gallons and I try and burn as much as possible each time out. Should I be refilling on the way home? I use startron or stabil every fill up. I recently read the top secret thread and most of the worry seemed to be targeted towards those who store their boats over winter. Like I said I run mine year round. Thanks for any advice, I've been told to stay away from any fuel additive that contains alcohol.
