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

Too late. Stabilizer must be added when the gas is fresh to do any good.
Siphon
the remaining gas out and use it in your car. Add some fresh gas with
stabilizer
to the boat's tank and run the engine enough to be sure that the carb and
lines
have fresh, stabilized gas in them.

Perhaps the OP put the gas in yesterday, ran off a 1/4 tank and now is
asking the question. Shouldn't be too late to add stabilizer if that's the
case. I try to remember to add the stabilizer at the beginning of the
season as I seldom use a full tank with my fishing motor.

Unstabilized gas lasts about 30 days at the most.

Do you have any authoritive source for that statement? Most of the oil and
gasoline posts here sound like urban legends.

This helps cure the urban legand[s]

Get a fresh 5 gallon can of lawnmower gas, get a whiff of it, and
leave it sit for a month,

then smell it and see if it's started to get "stale"

it happens around my place.

Good lord!

Good lord my butt. If you really believe that straight gasoline goes bad
after 30 days you probably also believe that the black helicopters are
circling your house every night. Park your car for 30 days; do you really
think you'll see a difference in the performance?

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.

Simple question for you Charlie: Do you believe that untreated gasoline in a
marine fuel tank is corrupted after 30 days?

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.
