Transmission: 15W50
The "W" on an engine oil bottle is short for weight. A bottle that says 15W50 will have the weight of the oil at 15 at the coolest point and 50 at its warmest point. If oil is too heavy in the colder months, it will gum up and the engine will not turn over to start.

First, just try a heavier grade oil. If you're using a 5W15, switch to a 10W30 or even a 15W50. That should help you get some more miles out of the engine.
