2003 Subaru Forester Oil Capacity

The 2003 Subaru Forester with the EJ251 engine takes 4.2 qt of engine oil, with 5W-30 listed as the oil grade. The Facts repeat the same EJ251 capacity and grade, so they provide one consistent specification rather than different figures for separate trims or engines.

Read the capacity as the stated oil amount and the grade as the listed oil viscosity. The supplied facts do not say whether the capacity applies to an oil change with a filter or without one, or whether the amount varies by service conditions. Confirm any amount or procedure not specified here on the vehicle’s door jamb or in the owner’s manual.

Only the EJ251 specification is provided for this year, so no comparison with other engines or trims can be made from these facts. If your Forester has a different engine or you need a more specific service-fill amount, verify the correct figure in the owner’s manual before adding oil.
