Cold weather is good for fuel storage, while starting the engine for few minutes is not.
All the prolonged idling does is washing the oil from cylinder walls and dump a doze of acids from cold startup into the crankcase.
Some people like to add Stabil to gas. I even bough a bottle years ago, but never used even on my boat that at one time had 2-years old gas. Since the boat is parked in hot spot and tank has open vent, the 2-years old gas lost the light fractions and the engine was smoking a bit on it, but it still run OK. Even my Honda lawnmower runs on gas left in it last summer just fine.
