Recommended Oil
API standard SM with the "Energy Conserving" logo is printed.
ILSA C standard, GF4 "Star burst mark" label is on the container.

The proper viscosity helps vehicle get good cold and hot starting by reducing viscous friction and thus increasing cranking speed.
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 may be used: API standard: SM or SL
SAE Viscosity No.: 30, 40, 10W-50, 20W-40, 20W-50.
