How to verify the exact oil for your vehicle
To ensure you use the correct oil for your specific Tucson, follow these steps:
- Check your owner's manual for the exact viscosity and specification (for example 5W-30 API SP/ILSAC GF-6 or 0W-20).
- Look at the under-hood oil fill cap or the engine oil label near the dipstick for the recommended grade.
- Enter your VIN on Hyundai's official service portal or contact your local dealer for model-specific requirements.
- Choose a synthetic oil that clearly states API SP (or SN/SM if SP is not available) and ILSAC GF-6, and meets OEM specs.
Using the correct oil helps maintain efficiency, emissions compliance, and engine longevity, and ensures warranty coverage when observed at service intervals.

Always verify the exact grade and specification for your trim and region in the owner's manual or via Hyundai's service resources, and choose a high-quality synthetic that meets those specs.
