Engine Lubrication: Specifications
SPECIFICATIONRecommended oil:
Oil corresponding to either of the following standards.
^ Those with the API standard SM or SN "Energy 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.
^ 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 SN
SAE viscosity No.: 30, 40, 10W-50, 20W-40, 20W-50
