Recommended oil:
Oil conforming to one of the following standard
- Those with an API standard SM "Energy Conserving" logo
- Those with ILSAC standard GF-4 "Star burst mark" label on the container
CAUTION:
It is acceptable to fill an engine with oil of another brand when replacing the oil, but make sure to use an oil with an API standard and SAE viscosity number 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.
- If the vehicle is used in regions of high temperatures or in other severe environments, use oil with the viscosities shown below.
API standard: SM or SL
SAE viscosity No.: 30, 40,10W-50, 20W-40, 20W-50
