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. |
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)
Scheme 20
Note. The proper viscosity oil helps the engine maintain its ideal temperature, and cranking speed increased by reducing viscosity friction in hot condition.
