2003 Subaru Outback Oil Capacity

The 2003 Subaru Outback’s oil capacity depends on which engine it has: the EJ253 takes 4.4 qt, while the EZ30D takes 5.9 qt. Both engines use 5W-30 oil, according to the listed facts.

Read the capacity as the amount associated with the engine code, not as a figure that applies to every 2003 Outback. Check the engine code before using either amount. The figures here distinguish the EJ253 from the EZ30D; they do not list differences by trim or other equipment.

Oil capacity can vary with the engine, so do not transfer one engine’s figure to the other. If you cannot confirm your engine code, or need a capacity for a vehicle configuration not covered here, check the door jamb or the owner’s manual.
