The proper viscosity helps vehicle get good cold
and hot starting by reducing viscous friction and
thus increasing cranking speed.
NOTE:
• When replenishing oil, it does not matter if the oil

to be added is a different brand from that in the en-
gine; however, use oil having the API classification
and SAE viscosity No. designated by SUBARU.
• If vehicle is used in desert areas with very high
temperatures or for other heavy duty applications,
the following viscosity oils may be used:
API classification: SL or SJ
SAE Viscosity No.: 30, 40, 10W-50, 20W-40, 20W-
