Recommended oil:

CAUTION:

It is acceptable to fill an engine with oil of another brand when replacing the oil, but make sure to use the following engine oil specified by Subaru.

Engine oil standard	Those with SN “Resource Conserving” logo in case of API standard.	or	Those with GF-5 “starburst mark” displayed on top of the container in case of ILSAC standard.
SAE viscosity No.

NOTE:

The proper viscosity oil helps the engine maintain its ideal temperature, and cranking speed increased by reducing viscosity friction in hot condition.

Caution

• Prior to starting work, pay special attention to the following:1. Always wear work clothes, a work cap, and protective shoes. Additionally, wear a helmet, protective goggles, etc. if necessary ...
