Just got back from about three hours on Lake Lanier. I topped up the 15 gallon tank adding about 5 gallons mixed at 32/1 before launching. Motor ran good. Some of the fuel in the tank is from last fall and some was added about a week ago. Recovered fuel added to the main tank anytime the one gallon has a half gallon or so. Usually on fill up. I very rarely run the 15 gallon tank to below about 3 gallons.
Something else to consider about using recaptured fuel. The composition of the recovered fuel changes. From what I’ve read condensed fuel is called ‘tailings’. Tailings are the heavier and less easily vaporized components of the fuel. I’m sure the oil component of the fuel/oil mix condenses out more easily, too.
So in the end I’m not real sure what the recovered fuel is composed of. It sure does look a darker blue than fresh gas/oil mix. The motor runs good and I feel good about it.
