The BT switched to a direct-injected FB25D, sharing its architecture with Impreza/Crosstrek/Forester. Capacity dropped from the prior port-injected FB25's 5.1 qt to about 4.4 qt with filter. Confirm on the dipstick after filling, as some dealer service tickets still reference the older 5.1 qt figure.

Shares its factory oil-change interval with the naturally-aspirated FB25D despite being turbocharged; some owners choose to shorten it given the added thermal load.

2020–2025 Subaru Outback oil: common questions

How many quarts of oil does a 2020–2025 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 2020–2025 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 2020–2025 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 2020–2025 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.
