Gas engines (including turbo and GDi)
For Kia gas engines, regular oil and filter changes are the foundation of a good maintenance plan, with published schedules commonly ranging from about 8,000 to 30,000 km or 5 to 24 months depending on engine and usage. Turbo and direct-injection (GDi/T-GDi) setups are more sensitive to oil quality and correct oil level, so it is worth checking the oil between services. Keep the air filter and spark plugs on schedule, and address any rough idle, hesitation, or warning lights early to protect the catalytic converter and turbo (if fitted). If your driving is mostly short trips, stop-start, or high heat, expect the shorter end of the interval range to be more realistic.
