All of this really depends on where you are at right now on mileage since your last oil change. The manufacturer suggests oil changes every 7 months or 7000 (7500?) miles, whichever comes first. The oil in our cars is a blend of natural oil and synthetic. You could always ask for pure synthetic but I personally think it would just be a waste since I would still suggest you change it ever 7mo/7k anyways (to stay under warranty). At the time of your oil change the manufacturer suggests you put in Techron fuel additive, I have the dealer put it in and make a note of it in case anything ever goes wrong I can prove I followed it to a T. You can always have them check your alignment but that is usually done at certain time/mileage marks and I'm honestly not sure what they are. If you curb your car often then maybe you could get it done sooner, I don't think most places charge to CHECK alignment, but they do usually charge to align them. If you are within 3k for your oil change I would call Kia service and ask them, they will usually let you go a could hundred miles over no big deal (or at least Nissan did). If you are a bit aggressive with your driving you may want to change sooner, driving harder (hard/quick acceleration) will help foul your oil quicker as well as warmer months (higher engine/oil temps). Cruising at 80 isn't great for the mileage but isn't really considered driving heavy as it's just a constant smooth thing. The thing I would check more than anything is tire pressure and make sure all of your lights work.
