Complete Oil Specifications
Your 2024 Kia Sorento with the 2.5L T-GDI turbocharged engine requires 0W-20 full synthetic oil meeting API SP / ILSAC GF-6A standards. At 6.1 quarts, the G4KH holds significantly more oil than the naturally aspirated 2.5L variant — do not confuse the two when servicing.
Quick Reference
| Specification | Value |
|---|---|
| Viscosity | 0W-20 |
| API Rating | API SP |
| ILSAC Rating | GF-6A |
| Capacity (with filter) | 6.1 quarts |
| Oil Filter | Kia 26350-2M000 |
| Normal Interval | 8000 miles |
Why 0W-20 is Critical for the G4KH Turbo
The G4KH Smartstream 2.5T uses both turbocharging and Gasoline Direct Injection — a combination that requires LSPI (Low-Speed Pre-Ignition) protection that API SP 0W-20 mandates. GDI engines accumulate fuel dilution in the oil more rapidly than port-injected engines, making thermal stability and detergency critical.
0W-20’s low cold-flow viscosity ensures the turbocharger bearings receive oil within milliseconds of cold startup — the most damaging operating condition for any turbocharged engine.
Using incorrect oil will:
- ❌ Risk LSPI — a single catastrophic pre-ignition event can destroy pistons
- ❌ Leave turbocharger bearings starved during cold-start lubrication delay
- ❌ Accelerate carbon buildup on GDI intake valves from inadequate detergency
Kia-Approved Oil Brands
-
✅ Quaker State Full Synthetic 0W-20
-
✅ Mobil 1 Advanced Fuel Economy 0W-20
-
✅ Valvoline Advanced Full Synthetic 0W-20
-
✅ Castrol EDGE Full Synthetic 0W-20
-
✅ Pennzoil Platinum Full Synthetic 0W-20
Kia recommends Quaker State as a preferred brand for Kia vehicles. Any major brand meeting API SP and ILSAC GF-6A provides equivalent protection.
Severe Service Check
You need the 5000-mile interval if you:
- Drive predominantly short trips under 5 miles in cold weather
- Tow trailers or carry heavy loads regularly
- Drive in heavy stop-and-go traffic in temperatures above 90°F
- Drive in dusty, rough, or unpaved conditions

Drain Plug Torque: 30 ft-lbs Replace the drain plug crush washer at every service to prevent weeping leaks.

Pro Tip: The 2.5T uses a cartridge filter housing accessed from underneath. Use a 27mm socket to open the cap and ensure the new O-ring seats fully in the correct groove — leaving it on the threads instead of the groove causes an immediate oil leak.
FAQs
What oil does a 2024 Kia Sorento 2.5T take? 0W-20 full synthetic oil meeting API SP and ILSAC GF-6A.
How many quarts does it need? 6.1 quarts with a new filter. Note: the naturally aspirated 2.5L Sorento uses only 5.1 quarts — the turbo takes significantly more.
Is the oil spec the same as the 2023 Sorento 2.5T? Yes. The G4KH Smartstream engine carries the same oil specification from 2023 to 2024.
Can I use 5W-30? Kia specifies 0W-20 for the G4KH Smartstream turbo in North America. Persistent use of 5W-30 may impair cold-start turbocharger protection.
How often should I change the oil? Every 8000 miles for normal driving. Use 5000-mile intervals for towing, short trips, or extreme temperatures.
