Stick with Severe OCI in Owner's Manual. I am familiar with Kia's. They are really hard on oil. Does yours have a turbo charger? In fact, I called the local Kia Dealer Service Dept concerning a recent purchase. They recommend full synthetic, but of course they up-sell.

Run a good synthetic from a major brand that meets the latest specs and you will be fine.
My commute is about 45 minutes each way, about 12~13 miles. But on bad days, or if I get out of the house later than I should, it could take up to an hour.
Even with the weekend trips I would consider a 5000 mile oci. Enjoy your new Palisade.
I agree with PimTac then get an UOA at 5000 and you'll have a much better idea of where you're standing.
Agreed 👍.. you've already spent $50g's.. what's another $20 on a UOA? There are plenty of reasonably priced syn blends and full syns that can do 7.5k. Heck, there are full dinos that can do 5k no sweat.. maybe even 7 in the right engine

Normal driving and 7500 easy after wear in maybe 10K. UOA after 2 OCI and after wear in should give you an idea of how far you can go. But, just BC TBN is fine does NOT mean the viscosity is in a good range or the EP additives are available. MaxD.. Una rápida lección de español ¡No hay ningún problema!

Appreciate all the responses, everyone! Lots of insight. I think I will fill with synthetic and maintain a 5000 interval for now, and consider doing UOA after a couple fills. To answer a few questions that were brought up: - No, my vehicle doesn't have a OLM, only a manually-set reminders based on miles. - And no, the engine isn't turbo, V6 GDI.

Not certain if it's still the case in California but Supertech 0w20 is $15 for 5 quarts. That's conventional price for full synth support. Auto parts stores be dammed.

Hyundai GDI engines are somewhat known as fuel diluters prior to 2020 (still too eartly to know about 2020's) ... Synthetic at less than 5K miles OCI is best (My 2017 GDI 2.4L Sonada's oil is toast by 4K miles of similar driving style as you ...
