Specified oil:
CAUTION:
• Use 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 SN “Resource Conserving” logo in case of API standard.
or

Those with GF-5 “starburst mark” displayed on top of the container in case of ILSAC standard.
0W-20 (synthetic oil)
