I never have found out what the newer Hyundai / Kia 2.4L non - turbo GDI engines used as a factory fill oil weight - anyone know ? ... I understand many Hyundai / Kia service centers use 5W30 so they can cover turbo & non - turbo engines without risk , however what about new non - turbo engines from the factory - venture to guess 5W20 of some sort ? ... Lastly , does Hyundai / Kia use a special high moly content oil as a factory fill as some Japanese auto makers use ? Thanks in advance ...
