Hi all,

The season is about to end and I have 3/4 tank of gas in the boat. What
are the proper storage procedure for the new and improved gasoline. I
assume you just pour in stabilizer but was concerned with the decay issue of
the ethanol.

Thanks

Ignore these guys and add stabilizer.

It is also a good idea to store the boat with either a full tank or a
completely empty tank. Gas expands and contracts a good deal with
temperature change and it increases the moisture in you tank when it
"breathes". So fill your boat the rest of the way after you add the
stabilizer. And run it on muffs for a few minutes to get the gas with
stabiliwer into the carb.

How much do you think gasoline expands and contracts with temperature
change?
1% ? 10% ? .01% ? How much is a "good deal"? Please be clear on the
coefficient of thermal expansion for liquid gasoline versus gasoline vapors.

The liquid gasoline expansion rate is almost 5 times higher than water.
In subjective language that is my "good deal".

There is a school of thought that you should fuel up in the morning
because you will get more gas by volume than you will in the afternoon.
I'm sceptical about that one because the gas in the underground tank
probably has a much smaller temperature range than an exposed tank.

I've read that a 15°F temperature change in gasoline will cause a 1% change
in volume.
