Turbo engines (Optima 2.0T, Sorento 2.5T) may benefit from more frequent oil changes.
"Severe service" conditions (heavy towing, extreme temps, city stop-and-go) typically halve these intervals. Always consult your vehicle's owner's manual for the authoritative schedule.

These are the terms for a new Kia. If you're buying a used 2020 NIRO, remaining coverage is usually pro-rated from the vehicle's original in-service date. Not all coverage transfers between owners — check with a Kia dealer for VIN-specific remaining warranty.
