Ok, will take into consideration as well.I think the same way but the more I read from experiences on this forum and my own in the shop, Hyundai/Kia probably chose to spec 5w20 for their engines in the interest of fuel economy over long term reliability.
Smoothness, oil burning, fuel dilution - these symptoms get somewhat cleared up with 5w30. Of course you can put that off to keep searching for another cause.
