Rows shaded above mark the major milestones. How you drive can shift these intervals, since severe conditions call for more frequent service. The K5’s real-world rhythm departs from this 7,500-mile grid in a few spots: oil & filter really runs closer to every 8,000 miles/12 months; the cabin air filter follows roughly a 24-month cycle (about every 24,000 miles); the engine air filter follows roughly a 36-month cycle (about every 36,000 miles); brake fluid gets exchanged every 48,000 miles/48 months; spark plugs on the 2.5L turbo GT are confirmed at 48,000 miles, then every 48,000 after — the 1.6L turbo base likely follows a similar turbo-length interval, though Kia hasn’t published an exact figure for it, so check with your advisor; and engine coolant is first flushed at 120,000 miles/120 months, then every 24,000 miles after. Some AWD-equipped 1.6T trims from this era carry a separate AWD driveline service with no confirmed interval published yet, so ask your service advisor what your specific trim needs. When in doubt, check your Owner’s Manual or ask a Dean McCrary Kia technician.

2023 K5 Service Questions
How Often Does a 2023 Kia K5 Need an Oil Change?⌄
Under normal driving, Kia calls for a full-synthetic oil and filter change every 8,000 miles or 12 months on the 2023 K5 — the same cadence no matter which engine you have. Conditions like frequent towing, short trips, dusty roads, or lots of idling count as severe use and shorten that window — many drivers in that category are better off every 4,000–5,000 miles.
Is Synthetic Oil Required for the 2023 Kia K5?⌄
Yes — Kia specifies full synthetic oil for both the 1.6L turbo and 2.5L turbo GT in the K5. It protects the direct-injection system and both turbochargers, and it holds up well through hot, humid Pine Belt summers.
When Do the Spark Plugs Need Replacing on a 2023 K5?⌄
On the 2.5L turbo GT, spark plugs come due at 48,000 miles under normal use. Kia hasn’t published a separate confirmed figure for the 1.6L turbo base, but a similar turbo-length interval is a safe bet — have your service advisor check what your specific trim calls for.
Does Staying on This Schedule Protect My Factory Warranty Coverage?⌄
It does. factory warranty remains active as long as factory-recommended maintenance gets done on time and documented. Service with our team and that record-keeping happens automatically.
