I second the recommendation for a full tank. I also have put gas line antifreeze in the tank along with fuel stabilizer. I know some people feel compelled to start a car up a time or two during the winter, but I've been told by a few people over the years whom I trust that this is not required and if the car is not brought up to full operating temperature, the resulting condensation is not good for the car. If you can't leave it alone, consider putting the battery in it once or twice over the winter and cranking it a few times to get the oil pressure up and the oil circulating, then take the battery back out. I have been storing at least one or two cars a year this way for almost 50 years and I've never once had an issue. I'm also in the northeast and likely a little further north than you. I've just put the freshly charged battery back in the car in the spring and they have always started right up.
