2015 Subaru Forester Oil Capacity

The 2015 Subaru Forester’s listed engine oil capacity is 5.4 qt for the FA20F and 5.1 qt for the FB25BA. The required oil viscosity also differs: the FA20F uses 5W-30, while the FB25BA uses 0W-20. Check the engine code for your vehicle before choosing the capacity or oil grade; these figures are not interchangeable.

Read each capacity alongside its engine code and viscosity, rather than treating it as a single amount for every Forester. The listed values describe the two engines shown for this year, so your engine determines which figure applies. The facts do not specify whether the amount includes an oil-filter change or provide a separate refill quantity. If you need a figure or instruction that is not listed here, confirm it on the door jamb or in the owner’s manual.
