Recommended oil:
Those with an API standard SM "Energy Conserving" logo or
ILSAC standard GF-4 "Star burst mark" label on the container
CAUTION:
When replenishing oil, it does not matter if the oil to be added is a different brand from that in the engine; however, use oil having the API standard and SAE viscosity No. designated by SUBARU.
NOTE:
If the vehicle is used in areas with very high temperatures or for other heavy duty applications, the following viscosity oils must be used: API standard: SM or SL
SAE Viscosity No.: 30, 40, 10W-50, 20W-40, 20W-50
SAE Viscosity No.: 30, 40, 10W-50, 20W-40, 20W-50
