Hyundai Sonata Oil Type and Capacity

Each row links to the full specification for that generation, including trim-by-trim breakdowns and the part numbers. Where engines within a generation differ, that page separates them.

The oil on a Hyundai Sonata is set by its generation, not its model year, so each generation has one page carrying the complete figures, part numbers and fitment notes for every year it covers.

How many quarts of oil does a Hyundai Sonata take?

It depends on the engine. The 2.5L 4-cylinder (Smartstream G4KN GDI) takes 6.1 quarts; The 1.6L Turbo 4-cylinder (Smartstream G1.6 T-GDI) takes 5.1 quarts; The 2.5L Turbo 4-cylinder (Smartstream G2.5 T-GDI, N Line) takes 6.1 quarts; The 1.6L Turbo Hybrid (Smartstream G1.6 T-GDI + electric motor) takes 5.1 quarts, all figures include a new filter.

What kind of oil does a Hyundai Sonata take?

0W-20 meeting API SP / ILSAC GF-6, full synthetic (required, not merely recommended). Other engines in this vehicle may differ; see the table above.

Can you use a different viscosity in a Hyundai Sonata?

The factory specification is 0W-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 Hyundai Sonata need an oil change?

7,500 mi / 6 months (normal); 3,750 mi (severe). Short trips, towing, extended idling, and dusty or very cold conditions all put the vehicle on the severe-service side of that interval.
