I'm no oil expert, but..........
I say change it. When in doubt, change it out. You can't hurt and can only help by doing so - if you are OK with the cost of 9.5 quarts of Mobil 1 and filter.
I'm like you, I will drive it in the winter if no salt and snow present, but - after last winter here in NE- who knows how long she will be garaged? I had my indie change the oil a few weeks ago, while it was in for new tires and alignment - even though I had only driven the car about 3,500 miles since the prior change. If I can sneak it out again in Jan/Feb, I'll change it again - regardless of miles.
