2003 Hyundai Elantra Oil Capacity

The 2003 Hyundai Elantra with the G4GC engine has an oil capacity of 4.2 qt and uses 5W-30 oil. These figures describe the engine and oil grade listed for this year; check that your vehicle has the G4GC before relying on them, since capacity and oil recommendations can differ by engine or model year.

Read 4.2 qt as the listed oil capacity, and 5W-30 as the listed oil viscosity grade. The capacity is a reference for an oil change, not a substitute for checking the level after filling. Add oil carefully and use the dipstick to verify the level, following the procedure in the owner's manual.

The facts provide one engine entry for this 2003 model and do not list separate values by trim. If your engine code, oil capacity, or recommended grade is not shown here, confirm the correct information on the door jamb or in the owner's manual.
