I have a 2007 Kia Sedona 3.8L V6 (185K miles) , I believe there is a "semi - controversy" in terms of what grade oil (5W20 vs. 5W30) to use ?
Something about smaller oil passageways in this engine design show it performs best with 5W20 while others say since 5W30 is also suitable (listed in the OM) and can be considered suitable as well ... *What says you Kia engine experts ?
