Personal opinion only, I don't think there's enough difference to make any
difference. I usually do sort of a combo of the two with my Ariens snow
blower. Letting the tank go low on gas (or siphon most of it out), I add a
shot of Stabil to the tank, let it run for about ten minutes or so until it
gets good and warm, then shut off the gas valve on the tank. The bowl
empties & it stalls, then I drain the oil & refill it, pop the plug out,
squirt some ND 30W into it, turn it over a few times with a cloth over the
plug opening, put the plug back in, refill the oil, & consider the engine
done. After that it's just a couple grease fittings, some WD40 on linkages,
etc, oil on the movable metals, & store it. It takes about thirty extra
seconds next spring to start it, but after coughing once or twice it springs
to life and gives me yet another year's service. Bought it in 1979. Only
part ever replaces is the throttle cable and the rubber-edged wheel inside
that spins the drive wheels. I especially love being able to "start & go"
in the spring that way. And it doesn't rust. Oh year, I replaced both belts
a few years ago too - boy is that a b_tch of a job! But, it's a faithful
ol' gal, still full of piss & vinegar.
If there's no gas shutoff (lawn tractors, etc.), I still do the same thing
but I leave a little more gas in the tank, maybe an eighth to a quarter
Oh, and pull the starter cord just before storing it to be sure the valves
close - set the choke full on; keeps moisture & spiders out of the
I guess it mostly depends on where you store it. If it's got a safe place
to winter over, fine; but NEVER leave gas in anything that's near sparks or
any source of heat! There you want to empty the tank completely.
