The 2019 Hyundai Tucson generally uses synthetic engine oil with a viscosity of 5W-30, though some engines or climate conditions may call for 5W-20. Always confirm the exact specification in the owner’s manual or on the under-hood oil label.
To understand the answer in more detail, the Tucson was offered with two gasoline engines in 2019: a 2.0-liter inline-four and a 1.6-liter turbocharged inline-four. While both engines rely on synthetic oil, the recommended viscosity can vary depending on the engine type and local climate. The following guidance summarizes typical recommendations and the standards to look for when selecting oil.
Engine options and oil recommendations
Different engines in the 2019 Tucson have their own oil recommendations. The list below covers the common guidance for these two powertrains.
Oil grade by engine
- 2.0L Nu I4 engine: usually synthetic oil with viscosity of 5W-30; API SN or newer, ILSAC GF-5 or newer.
- 1.6L turbocharged I4 engine: typically synthetic oil with viscosity of 5W-30; API SN or newer, ILSAC GF-5 or newer.
Note: Depending on climate and driving conditions, the manual may allow or require alternative viscosities (for example, 5W-20 or other grades). Always verify the exact specification for your vehicle in the owner's manual or on the under-hood oil cap/sticker.
Oil capacity and service intervals
The oil capacity varies by engine, and you should consult your owner's manual or the under-hood placard for the precise amount. When using synthetic oil, many owners follow a typical change interval around every 7,500 miles (or as recommended by Hyundai for your driving conditions). Severe driving conditions may warrant more frequent changes.
When selecting oil, prioritize products that meet the appropriate standards and are labeled as full synthetic. Look for oils that specify API SN or newer and ILSAC GF-5 or newer, and ensure the viscosity matches what your engine requires as listed in the manual.
Practical tips for choosing oil
Before you buy, keep these considerations in mind to ensure compatibility and warranty compliance.
- Choose a full synthetic oil rather than conventional for better protection and longer change intervals.
- Match the viscosity to what is specified for your engine and climate (common options include 5W-30 or 5W-20).
- Verify the oil meets API SN or newer and ILSAC GF-5 or newer standards.
- Use a quality oil filter and follow Hyundai’s recommended service intervals.
In practice, always cross-check the exact grade, capacity, and interval with the 2019 Tucson’s owner’s manual or Hyundai’s official service resources, as the specifications can vary by engine and market.
Summary
The 2019 Hyundai Tucson typically uses synthetic engine oil with a viscosity of 5W-30, with 5W-20 as a climate- or engine-specific alternative in some cases. The two engines—the 2.0L Nu I4 and the 1.6L turbo—both require synthetic oil, and the exact grade should be confirmed in the owner’s manual or on the under-hood label. For best results, choose a full synthetic oil that meets API SN or newer and ILSAC GF-5 or newer standards, and follow the recommended service intervals for your driving conditions.
