I don't care if you buy it or not, it is true. Your car loosens up some, but not as much as when it is warmer out. The engine and tranny loosen up to near normal, but the wheel bearings do not. Yes cars do run a bit richer when it is cold too. A smaller factor in play is the air is more dense so it causes more drag on the car going through the air. There is less drag on the tires though, since they are harder when it is cold out.
