The proper viscosity helps car get good cold and hot starting
by reducing viscous friction and thus increasing cranking
speed.
a. SAE 5W·JO is not recommended for sustained high speed
driving.
b. If vehicle is used in desert areas or areas with very high
temperatures or for other heavy duty applications, the
following viscosity oils may be used:
"30,40, 10W·50, 20W·40, 2OW-50"
c. 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 classification and SAE viscosity No.
designated by SUBARU.
