Recommended oil:
Items having the API standard SL "Energy Conserving" logo
ILSAC standard GF-4 Star burst mark label on the container
The proper viscosity oil helps the engine maintain its ideal temperature, and cranking speed increased by reducing viscosity friction in hot condition.
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:
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
