Giving directions to my college daughter to school was pretty easy the first time; take I-75 over the big bridge, then drive one more hour. When you see the sign for toll at the Canadian border, exit right to Lake Superior State University. The Neon sits on a hill all winter with a nice view of Lake Superior. The wind whips over frozen Whitefish Bay (Edmund Fitzgerald sank there)right into the grill of the Neon. Extreme condition. Cold crank nightmare. She has a new battery in her '03 Neon, new ATF, coolant and plugs, 68,000 miles. Question is what oil is best for extreme cold, short trips and a 20 year-old mechanical zero? That Neon clanked in the cold on Mobil 1. The Valvoline Maxlife Synthetic 5w30 fixed the piston slap noise in cold weather. Problem is, I can't find Maxlife Synthetic 5w30 anywhere. I considered a 5w-20, but don't want the oil consumption (she never never checks oil). I'm thinking of Pennzoil Platinum 5w30. The test data from Amsoil shows a CCS Viscosity test result of 4020 CCS viscosity - best of test. Any suggestions?
