SAE viscosity No. and applicable temperature |
CAUTION:
• 0W-20 can only be used on SOHC models.
• 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
