Should I keep my gas tank full in the winter, so it does not freeze?

Pure unleaded freezes at around minus 150F, Dom so you should be OK. On a bike or car it pays to keep the tank topped up to avoid rust if the vehicle is laid up for any length of time. Obviously any water in the gas will freeze at its normal freezing point.

Yes, but not so it doesn't freeze. Alcohol absorbs water so since most gasoline sold today is either 5% or 10% alcohol, you probably don't have much if any water in your tank. A half tank of fuel will collect moisture from the atmosphere and eventually your performance will suffer. Also, if everyplace is closed due to heavy snow, you have a full tank and can last out the storm. Get stuck and you have enough fuel to keep yourself warm until you can get out.

If you're really worried about it, you can get a bottle of Heet which is alcohol and will absorb moisture. Any alcohol will work but NOT rubbing alcohol as it has water added and can't absorb anymore.
