2012 Hyundai Elantra Oil Capacity

The 2012 Hyundai Elantra’s listed engine oil capacity is 4.2 qt for both engines. The recommended oil viscosity depends on which engine is fitted: G4NA uses 5W-30, while G4NB uses 5W-20. Check the engine identification before choosing oil, since the capacity is the same but the listed viscosity differs.

Read 4.2 qt as the listed oil amount for either G4NA or G4NB. The facts do not say whether this amount includes an oil-filter change, so confirm the procedure and fill level in the owner’s manual. Do not assume that matching capacity means the two engines use the same oil grade.

These figures apply to the 2012 model and distinguish the engines rather than giving separate amounts by trim. If your vehicle’s engine or required oil specification is unclear, confirm it in the owner’s manual. For any oil capacity or viscosity figure not listed here, check the door jamb or owner’s manual.
