I use Stabil year round for all my 4 cycle engines(and my old cars), a 5gal
can will last me a while , so why not?
I use Tanaka 2 cycle oil mix for all my 2 cycle stuff, it has stabilizer, is
low ash content, I've left it in my chain saw for upwards of two years and
it will fire right up. And the idea of leaving some fuel in tank/carb makes
sense for keeping moisture out.

Well the trees are turning green and the snow's finally gone, so that
means it's time to put the snowblower away. After I run it for a little
while to warm it up and then change the oil, should I keep running it to
drain the gas from the tank/carb, or should I keep gasoline in the tank
and rely on gasoline stabilizer? (The gas in the tank already has
STA-BIL in it.)

I figure that draining the gas completely will ensure no varnish/junk
build up in the fuel system, but keeping fuel + stabilizer in the tank
will prevent moisture in the fuel system/carburetor. Which is better?
