The 2020 Hyundai Sonata generally requires a synthetic engine oil with a viscosity of 0W-20. This specification is recommended across its common engines, and you should confirm the exact requirements in your vehicle’s owner’s manual or with a Hyundai dealer. The short answer is: use 0W-20 synthetic oil that meets API SN Plus or newer standards.
Official oil specification for the 2020 Sonata
The official specification from Hyundai’s owner manuals specifies 0W-20 synthetic oil for the 2020 Sonata’s engines, including the 2.5L GDI and the 1.6L turbo variants. Oil that meets the API SN Plus or newer standard (and is ILSAC GF-6 compatible) is considered acceptable. Always verify the exact requirement for your market, as specifications can vary by region.
The following items summarize the essential requirements you should verify when buying oil for a 2020 Sonata.
- Oil type: Synthetic engine oil (not conventional mineral oil) is recommended.
- Viscosity: 0W-20 is the standard specification for most trims in the 2020 model year.
- API/ILSAC compliance: Oil should meet API SN Plus or newer and be compatible with ILSAC GF-6 (or newer) standards.
- Vehicle compatibility: Ensure the oil you choose is approved for Hyundai vehicles and matches the 0W-20 specification listed in your manual.
Using the recommended oil type and viscosity helps protect the engine, maintain fuel economy, and preserve warranty coverage. If you are unable to obtain 0W-20 for any reason, consult your dealer or the owner’s manual for acceptable alternatives in your market.
