2019 Kia Optima LX 2.4 engine
I know 5w-20 but what brand and full synthetic or semi synthetic.
I have used Motorcraft 5w-20 semi synthetic oil on my last two new cars with good luck.
I just got a reply from our local kia service department, and they say they use Mobile 1 semi synthetic, but it is user preference as long as the oil meets the specification, which Motorcraft does.
So they answered my question.
