2018 Subaru Outback Oil Capacity

The 2018 Subaru Outback oil capacity depends on which engine it has: the EZ36D takes 6.9 qt, and the FB25B takes 5.1 qt. The listed oil grades are 5W-30 for the EZ36D and 0W-20 for the FB25B. Match the engine code to the vehicle before using either capacity or grade; these figures are not interchangeable.

Oil capacity is the amount listed for the specified engine, while the grade identifies the recommended oil viscosity. The figures here apply to the 2018 model and vary by engine: the EZ36D has the larger listed capacity and uses 5W-30, while the FB25B has the smaller listed capacity and uses 0W-20. The supplied facts do not list differences by trim, so do not assume trim alone determines which figures apply.

If you cannot confirm whether your Outback has the EZ36D or FB25B, check the vehicle documentation. For any capacity or oil grade not listed here, or to verify the correct specification for your vehicle, confirm it on the door jamb or in the owner's manual.
