That's way too conservative. It should be good for at least 6 months
under normal storage conditions, a year or more if a bit of Sta-Bil is
added.

The important thing is to not let stale fuel stand in the carburetor
or injection system. Disconnect the fuel hose and let the engine run
out of gas before leaving it unused for more than a month or so.

But then don't you have to drain the gas from the carburetor bowl. I've had
the worst problem with that little bit of gas solidifieing in the bowl and
high speed orifice over the Winter. I've had to disassemble the carburetor
on my outboard, my garden tractor, and my push mower the last two years
because of this problem and I used Stabil and ran the engines out of gas.

Two things: The last gas you put in the tank should be fresh gas with
a DOUBLE dose of stabil. You can put in the excess stabil without any
ill effects. Then, don't make the mistake of thinking you should run
the engine dry. That always leaves small amounts of fuel coupled with
large amounts of air. It also allows seals and seats to dry out, which
is BAD. You want the entire fuel system as full as possible during
layovers of less than 2 years.

BTW - there is now a Stabil specifically for marine use, and gas with
ethanol. It's got twice as much goodness in every drop.
