It's currently -2 degrees Fahrenheit outside (Chicagoland area). My '94 T-Bird is sitting out in my driveway with 5W-20 in it for the first time in temps this cold (I've always used 5w30 in the past). We'll see how it starts in the morning! These kinds of nights would always make my first few seconds after startup an unbearable, noisy experience. If I had bought one of those oil pan warmers, I wouldn't be worried right now...
