Service manual recommends 5w-30 for all seasons, and 10w-30 if it never gets too cold, but with higher mileage, 10w-30 or 10w-40's okay. I use it all year round. Synthetic will alway out perform conventional.
I switched from Mobil 1 to Castrol Syntec since they offer a 10w-40.
ina96se, I don't think sythetic oils will go up in price since they are synthetic, as in man made, and does not contain petroleum.
