- Viscosity: 5W-20 is standard for most climates; 5W-30 can be used in hotter climates or as specified by the owner's manual. Use oil that meets Hyundai’s requirements.
- Oil specification: Choose an oil that meets modern automotive standards and is suitable for gasoline engines, with the label indicating compatibility with Hyundai vehicles. If in doubt, opt for a conventional or synthetic 5W-20 that carries appropriate API/ILSAC certifications.
Using the correct viscosity and certified oil helps maintain engine longevity, fuel efficiency, and warranty compliance. Always verify the exact specification in your manual, as recommendations can vary by market or production year.

- Gather supplies: 4.2 quarts of oil (plus a new filter), a drain pan, wrench for the drain plug, funnel, replacement drain plug washer, and cleaning rags.
