Oil Viscosity & Change Intervals

Engine

Vehicle Information: Year: 1999; Total Mileage: 56000;

I change my Mobil 1 oil every 7,500-10,000 miles. It's not always convenient to try and time it so that I use one viscosity during warmer months, and another during colder ones. Is it recommended to use the newer 0W-40 all year-round? Or is it still better to switch between 5W-30 and 15W-50?Also, do you recommend any additives of any kind to either the oil or gasoline?
