Agree. Too much oil for that change interval. You could go 7k with highway driving.
Seems like both of you are too focused on the numbers of 5k vs 7k, BUT you both fail to see past that blanket statement. Look deeper. This is a small 1.6L Direct Injected engine pulling a nearly 3000lbs metal shell around town. Believe it or not, but the oil in this vehicle will be working a lot harder, as compared to a 2.0L or 3.0L+ size engine in a similarly weighted vehicle. Therefore the OCI needs to be adjusted accordingly.
5k OCI with synthetic would be ideal, just make sure to use OEM oil filter. Kia/Hyundai engines are very picky about their oil filters.
