Specified oil

CAUTIONUse 0W-20 (synthetic oil). It is acceptable to fill an engine with oil of another brand when replacing the oil, but make sure to use the following engine oil specified by Subaru.

Note. The proper viscosity oil helps the engine maintain its ideal temperature, and cranking speed increased by reducing viscosity friction in hot condition.

Engine oil standard SAE viscosity No. Those with the API standard SM "Energy Conserving" or SN "Resource Conserving" logo. or Those with the ILSAC standard GF-4 or GF-5 "starburst mark" displayed on top of the container. 0W-20 (synthetic oil)

CAUTION

  1. Prior to starting work, pay special attention to the following: Always wear work clothes, a safety cap, protective shoes. Additionally, wear a helmet, protective goggles, etc. if necessary. Protect the vehicle using a seat cover, fender cover, etc. Prepare the service tools, clean cloth, containers to catch grease and oil, etc.
  2. Prepare a container and cloth when performing work which oil possibly spills. If oil spills, wipe it off immediately to prevent from penetrating into floor or flowing out for environmental protection.
  3. Vehicle components are extremely hot immediately after driving. Be wary of receiving burns from heated parts.
  4. When performing a repair, identify the cause of trouble and avoid unnecessary removal, disassembly and replacement.
  5. Before disconnecting connectors of sensors or units, be sure to disconnect the ground cable from battery.
  6. Always use the jack-up point when the shop jacks or rigid racks are used to support the vehicle.
  7. Remove contamination including dirt and corrosion before removal, installation, disassembly or assembly.
  8. Keep the removed parts in order and protect them from dust and dirt.
  9. All removed parts, if to be reused, should be reinstalled in the original positions with attention to the correct directions, etc.
  10. Bolts, nuts and washers should be replaced with new parts as required.
  11. Be sure to tighten the fasteners including bolts and nuts to the specified torque.
  12. If the engine oil is spilt over exhaust pipe or the under cover, wipe it off with cloth to avoid emitting smoke or causing a fire.
  13. Follow all government and local regulations concerning disposal of refuse when disposing of oil.
