The darker rows flag the bigger milestone visits, and any interval here can move up if you're driving in severe conditions. In practice the K5 runs a little ahead of this 7,500-mile grid: oil changes land closer to every 8,000 miles or 12 months; the cabin filter is more of a ~24-month item, swapped near 24,000 miles; the engine air filter follows roughly a 36-month rhythm around 36,000 miles; brake fluid gets exchanged at 48,000 miles/48 months; spark plug timing splits by engine — 96,000 miles for the 2.5L, but only 48,000 for the 2.5L turbo GT (shown on the closest 7,500-mile row to the 2.5L number); and coolant is first serviced at 120,000 miles, then every 24,000 after. For your specific K5, check the Owner’s Manual or ask a Dean McCrary Kia technician.

2025 K5 Maintenance FAQs
How Often Should I Change the Oil on a 2025 Kia K5?⌄
Both K5 engines share the same rhythm: full synthetic oil and a filter change every 8,000 miles or 12 months under typical driving. That gap closes up for severe-duty use — think regular towing, short hops, dusty roads, or lots of idling — where 4,000 to 5,000 miles between changes is more realistic.
Does the 2025 Kia K5 Require Synthetic Oil?⌄
It does, for either the 2.5L or the 2.5L turbo GT. Full synthetic keeps the direct-injection system protected — and the GT's turbo, too — and it holds up much better through a muggy, hot Pine Belt summer than conventional oil would.
When Should I Replace the Spark Plugs on a 2025 K5?⌄
The engine determines the timing: roughly 96,000 miles for the naturally aspirated 2.5L, versus 48,000 miles for the 2.5L turbo GT, which runs hotter and wears plugs down faster.
Does Following This Schedule Protect My Factory Warranty Coverage?⌄
It does. factory warranty remains active provided you keep up with factory-recommended service on time and the records show it. Book with our team and each visit gets logged for you automatically.
