CAUTION:
It is acceptable to fill an engine with oil of an-
other brand when replacing the oil, but make
sure to use an oil with an API standard and SAE
viscosity number specified by Subaru.
NOTE:
If the vehicle is used in regions with high tempera-
tures or in other severe environments, use oil with
the viscosities shown below.
