Winter Boat Storage - Gas?

[BigLew]

Now this is a timely question.

I have always stored with my tanks full in order to reduce available humidity for condensation. However, now with ethanol in the gas and thus a shorter shelf life I would be very interested in the opinion of others.

With regards to storing fuel with or without oil mixed, I would tend to go with unmixed as you described.

I always filled it before ethanol. This year I drained the gas tank. We'll see what happens.
