Quick Reference
| Specification | Value |
|---|---|
| Viscosity | 0W-20 |

| ILSAC Rating | GF-6A |
| Capacity (with filter) | 6.1 quarts |
| Oil Filter | Hyundai 26350-2S000 (Cartridge Style) |

*Note: If you have the 2.5L Turbo (Smartstream G2.5T) model, the recommended viscosity is 0W-30.
Why 0W-20 is Critical for the Smartstream GDI Engine
The Smartstream G2.5 GDI engine uses Gasoline Direct Injection. API SP–rated 0W-20 oil is formulated to mitigate carbon buildup on intake valves — a known characteristic of GDI engines — and provides rapid lubrication to the timing chain system at cold start.
Using incorrect oil will:
- ❌ Accelerate intake valve carbon deposits
- ❌ Slow cold-start lubrication to timing chain components
- ❌ Reduce fuel efficiency
