Recommended oil:
Oil which meets the following specification:
• For API standard, those with the SM or SL “Energy Conserving“ logo.
• For ILSAC standard, those with the GF-4 or GF-3 “Starburst mark” displayed on top of the container.
• For ACEA standard, those with the A1, A2, or A3 displayed on top of the container.

SAE viscosity No. and applicable temperature |
CAUTION:
• Do not use 0W-20 for turbo 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:
If the vehicle is used in regions with 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
