I just think winter is hard in a car. Period. The whole car. Start your car up in ten degrees bellow zero temperatures and drive to work. You’re going to experience some stuff, some weird stuff (sometimes). I’ve had my blower motor start squeaking. I’ve had my dash board start blinking (alternator maybe??). Windshield wipers frozen to the windshield. The suspension, I swear, feels like a bag of rocks until it too warms up a bit.
And winter is hard on oil. It doesn’t reach operating temps quick enough (or at all). There’s too many temperature fluctuations...too many cool downs, too many cold starts, too many trips where it never even reaches a point where you’ll burn off condensation. You’re getting maybe some more fuel dilution. Never mind the road SALT. All over that car...bypassing your air filter. I hate winters.
