Recommended oil:
Oil corresponding to either of the following standards.
• Those with the SM or SL “Energy Conserving” logo in case of API standard
• Those with the GF-4 or GF-3 “starburst mark” displayed on top of the container in case of ILSAC standard
• Those with A1, A3, or A5 displayed on top of the container in case of ACEA standard

CAUTION:
• Do not use 0W-20 for 2.5 L model.
• 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 SL
SAE viscosity No.: 30, 40, 10W-50, 20W-40, 20W-50
