The synthetic will not turn into honey in the winter like regular oil does. I doubt you'll notice hard starting in the winter. I doubt you need the 15-50 but it won't hurt anything. I always use mobil 10W30 for the engine and amsoil 20W50 in the 5spd transmission. I have heard thicker oil can lower your fuel mileage by 1 or 2 mpg so maybe you can let us know.
