What kind of oil does a 2017 hyundai tucson take?

You can use either A5W-20 or 5W-30 oil for Your 2017 Hyundai Tucson and the oil capacity iS4.2 quarts. Which oil You choose mostly depends on the environment that You do most of Your driving in. The 5W-20 is popular because it's good for people in colder climates and it also gives You slightly better fuel efficiency by creating less drag on the engine parts because it's less viscous than the 5W-30. You should also consider using a full synthetic oil as it offers good long term protection for Your engine and You can get away with doing oil changes less frequently. The slightly higher cost of synthetic is well worth it for the benefit of protecting from possible damage. -
