The owners manual states 4.25 quarts with the filter changed. Although 3.5 quarts usually gets me to the max mark when I change my oil (same car - 06 Kia spectra 2.0).

Assuming your engine is a 1.8L, it should take about 4.5 - 5.0 quarts. My 2002 Spectra takes 4.5. Hope that helps.
Change the oil & filter every 5,000 miles if you use conventional oil and every 7,500 if you use synthetic.

The oil capacity of the 2003 Kia Rio engine is 3.6 Quarts.
