In short, the 2014 Hyundai Tucson generally uses SAE 5W-20 engine oil, with synthetic oil recommended. In hot climates or under severe driving conditions, SAE 5W-30 may be used as an alternative.
To understand why and how this applies to the two common engines offered in 2014 Tucson models, it helps to look at the official guidance. The Tucson was available with two gasoline engines that year, and both follow the same basic oil specification for normal operation. The guidance emphasizes using a high-quality oil that meets industry standards and aligning viscosity with climate and driving conditions.
Engine oil recommendations
The following outlines the recommended oil grades for the two common engines in the 2014 Tucson.
- 2.0L inline-4 engine: SAE 5W-20 oil, API SN or ILSAC GF-5; synthetic oil is preferred, though 5W-30 can be used in hot climates or under severe service.
- 2.4L inline-4 engine: SAE 5W-20 oil, API SN or ILSAC GF-5; synthetic oil is preferred, with 5W-30 acceptable in hot climates or under severe service.
When in doubt, always refer to the owner's manual for your exact engine and regional recommendations, and follow Hyundai's service interval guidelines. Using the recommended oil helps ensure proper lubrication, fuel efficiency, and engine longevity.
Summary
The 2014 Tucson commonly requires SAE 5W-20 motor oil, with synthetic oil recommended for best protection. In hotter climates or under severe service, SAE 5W-30 is an acceptable alternative. Verify your specific engine and climate requirements in the owner’s manual to confirm the exact specification.
