Ok changed out my oil and filter yesterday. Very easy to do on this car hardest part is filling blue factory filter with oil. Oil capacity while reasearching online said 3.8 however I just put 3.2ish quarts( not exact with 5 gallon container) in and found it on full. How come specs on new car could be wrong. I did not take my car back to Doug Smith Kia i do not like fact they put 5w30 oil in and overfill every time. If dealer can not do it correct I now will change it myself. Car runs better now go figure with 5w20 in because A not over filled and B thinner oil works better in variable valve timing.
