Oil capacity by engine
| Engine | Oil Type (viscosity) | Capacity w/ Filter | Capacity w/o Filter | Notes |
|---|---|---|---|---|
| 2.5 GT, 4D Sedan | ILSAC GF-4, API - SM or SL, SAE 5W-30 | 4.20 QTS. | — | Engine Oil viscosity (thickness) affects fuel economy. Oils of lower viscosity provide better fuel economy. However, in hot weather, oil of higher viscosity is required to properly lubricate the engine. API SM or SL SAE 30, 40, 10W-50, 20W-40, 20W-50. You may use a synthetic motor oil if it displays the API Certification Seal, and it is the proper weight. |
