2018 Subaru Forester Oil Capacity

The 2018 Subaru Forester’s oil capacity depends on its engine: the FA20F takes 5.4 qt, while the FB25BA takes 5.1 qt. Use the engine code to find the applicable capacity and oil grade; the figures are not interchangeable between engines.

The listed capacities are the amounts associated with each engine, and the recommended oil grade differs as well: 5W-30 for the FA20F and 0W-20 for the FB25BA. Check the vehicle’s engine identification before choosing oil, rather than relying on the model name alone.

These facts apply to the 2018 model year and distinguish the two listed engines. If your vehicle’s engine or trim does not match either listing, or you need a figure not shown here, confirm the correct capacity and oil grade on the door jamb or in the owner’s manual.
