Johnny.....I operate on a 5 month use and 7 month storage schedule.
Manual says to treat gas and run for a bit and then fog

In the spring I burn off the previous years treated gas and then change
my water filter. Motor starts up right away and might smoke for a
couple of minutes...but works well after warming up.
Why would you keep gas over the winter? When you cover the boat for
winter, pour the gas in the RAV4 from all the gas cans. Start new in the
spring. I have had problems with my boat and old gas after an extended
layup. But my tank is harder to empty. 70 gallons.

Some of us don't live in nice warm climates. I keep at least 5 gallons
of gas handy for the snowblower and the little generator in the winter.
It's stored outside and I add the recommended amount of Stabil to it.

Last winter I had a 5 gallon jug and a 1 gallon jug sitting outside both
of which were promptly buried under 5 feet of snow. Fortunately,
we never lost power all winter and the snow was too deep to use the snow
blower on. I just emptied both in my truck a couple of weeks ago.
Truck happily burned it with no hiccups.

I also had about half a gallon of gas mixed with 2 stroke oil that I use
for my chainsaw. It sat for over a year with Stabil in it. I've been
doing some serious tree trimming in the past couple of weeks and the
chain saw runs just fine on the old gas. Again, stored outside, buried
in snow during the winter and over a year old.

For some reason 2 strokes have always seemed more tolerant of older
fuel. Possibly the carbs have bigger passages or some such.



Quality 2-stoke oil has stabilizer in it already. The carb is the usual
victim in either scenario - two or four stroke. Gummed up gas will make
it run like crap - or not at all. If you ever had to keep the choke on
to run a small gass engine you had a fouled carb.
