WE recommend 5W30
For a 2002 Kia Sportage the recommended oil to be used is a 10W-30. Most vehicles use this weight of oil. Depending on the climate it is best to stick with the recommended oil weight for your vehicle.
or mopil xhp that's very good the 2003 kia optima uses 5w-30
At the bottom of the engine block.
To remove the oil pump from a 2002 KIA Optima V6, first, drain the engine oil and disconnect the battery. Remove the oil pan by taking out its bolts, then unbolt the oil pump from the engine block. Carefully pull the oil pump out, ensuring no debris falls into the engine. For reinstallation, reverse the process: position the new or cleaned oil pump, secure it with bolts, reattach the oil pan, and refill with oil before reconnecting the battery.

Check the oil/crankcase fill cap. Most vehicles nowadays only require 5W-20, maybe 5W-30....of course, weather conditions can affect the oil you should use though!
Use exactly the weight that is recommended by Kia.
For the 2001 kia optima I have found the oil filter between the front passenger side tire and the engine. You can see it if you turn the wheels all the way to the left, although it helps if the filter cover is a bright color. To change it I had to remove the tire.
