The 2020 Hyundai Tucson uses synthetic engine oil, with the viscosity depending on the engine: 0W-20 for the 2.0-liter engine and 5W-30 for the 2.4-liter engine. Both are typically synthetic and meet ILSAC GF-5 or GF-6 standards. Always check your owner's manual for the exact specification for your vehicle.
The question depends on which engine your Tucson has. Hyundai offered two gasoline engines in the 2020 model year, and the oil grade is specified per engine and climate. This article outlines the official guidance for the two engine options and how to apply it when buying oil or scheduling maintenance.
Engine-specific oil recommendations
The following guidance mirrors what Hyundai and the owner's manual typically specify for the Tucson's two engine options in 2020 models.
- 2.0-liter engine (Nu): Synthetic motor oil, typically 0W-20, meeting ILSAC GF-5 or GF-6 standards. Use oil that is suitable for gasoline engines and meets the manufacturer's specification.
- 2.4-liter engine (Theta II): Synthetic motor oil, typically 5W-30, meeting ILSAC GF-5 or GF-6 standards. Use oil that matches the manufacturer's specification for this engine.
Note: In very hot climates or under demanding conditions, there may be regional allowances; always verify the exact viscosity and standard in your vehicle's owner's manual or with a Hyundai dealer. The viscosities above reflect common recommendations for the respective engines in the 2020 Tucson lineup.
Other considerations and how to apply the guidance
Where to verify the specification
For the most accurate guidance, refer to the vehicle's owner's manual under the Engine Oils section. Hyundai's customer portal and official service literature list the accepted oil grades and specifications for your VIN. If in doubt, contact a Hyundai dealership to confirm the exact viscosity and standards for your engine and local climate.
When selecting oil, ensure it is fully synthetic and meets the listed standards (ILSAC GF-5 or GF-6 and applicable API certification). Using the wrong viscosity or non-synthetic oil can affect engine performance, efficiency, and warranty coverage.
Summary
In brief, the 2020 Hyundai Tucson uses synthetic engine oil with viscosities tied to engine type: 0W-20 for the 2.0-liter engine and 5W-30 for the 2.4-liter engine. Both should meet ILSAC GF-5 or GF-6 standards and be appropriate for gasoline engines. Always consult the owner's manual or a dealer to confirm the exact specification for your vehicle.
