2015 Hyundai Elantra Oil Capacity

The 2015 Hyundai Elantra takes 4.2 qt of engine oil, with the recommended viscosity depending on engine code. Use the engine code to choose the matching oil specification: G4NA uses 5W-30, while G4NB uses 5W-20. The capacity is the same for both engines, but the listed viscosity differs.

Check the vehicle’s engine code before selecting oil; the model year alone does not distinguish between these specifications. The capacity is the listed oil amount, while the viscosity identifies the recommended oil grade. If your engine code or required capacity is not shown here, confirm the information on the door jamb or in the owner’s manual.
