Subaru Outback 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 Subaru Outback 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 Subaru Outback take?

It depends on the engine. The 2.5L 4-cylinder (FB25D, direct-injected) takes 4.4 quarts; The 2.4L Turbo 4-cylinder (FA24F) takes 4.8 quarts, all figures include a new filter.

What kind of oil does a Subaru Outback take?

0W-20 meeting API SN/SP / ILSAC GF-5/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 Subaru Outback?

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 Subaru Outback need an oil change?

6,000 mi / 6 months (normal); 3,000 mi / 3 months (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.
