Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-07-18
When to change the oil on a 2021-2024 (DL3) Kia K5, and what oil it takes.
| Oil change interval | 7,500 mi / 12 mo normal; 3,750 mi / 6 mo severe |
|---|---|
| Engine / oil | 1.6L turbo or 2.5L turbo (GT); 0W-20 / 0W-30 (2.5T); 8-speed auto / 8-speed wet DCT (GT) |
| Oil filter | Replace with every oil change |
Kia K5 note: Turbo across the range (1.6T or 2.5T GT), so plan on ~45k plugs. Mechanical sibling of the Hyundai Sonata; the GT's 8-speed wet dual-clutch is a different animal to service.
