2015–2019 Hyundai Sonata oil: common questions
How many quarts of oil does a 2015–2019 Hyundai Sonata take?
- It depends on the engine. The 2.4L 4-cylinder (Theta II GDI) takes 4.8 quarts; The 1.6L Turbo 4-cylinder (Gamma T-GDI, Eco) takes 4 quarts; The 2.0L Turbo 4-cylinder (Theta II Turbo GDI) takes 4.2 quarts; The 2.0L Hybrid / Plug-in Hybrid (Nu 2.0L GDI + electric motor) takes 4 quarts, all figures include a new filter.
What kind of oil does a 2015–2019 Hyundai Sonata take?
- 5W-20 meeting API SN or later. Other engines in this vehicle may differ; see the table above.
Can you use a different viscosity in a 2015–2019 Hyundai Sonata?
- The factory specification is 5W-20 and no alternate grade is listed for this engine. Modern variable-valve-timing hardware is sized around the specified viscosity, so substituting a thicker oil is not a free choice.
How often does a 2015–2019 Hyundai Sonata need an oil change?
- 7,500 mi / 6 months (normal); 3,750 mi (severe service). Short trips, towing, extended idling, and dusty or very cold conditions all put the vehicle on the severe-service side of that interval.
