Engine Lubrication
SPECIFICATIONRecommended oil:
Oil corresponding to either of the following standards.
^ Those with the API standard SM "Energy Conserving" or SN "Resource Conserving" logo.
^ Those with the ILSAC standard GF-4 or GF-5 "starburst mark" displayed on top of 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.
