J Recommended grade and viscosity
CAUTION
Use only engine oil with the recommended grade and viscosity.
Oil grade: API classification SJ or SH with the words “ENERGY
CONSERVING II” (if you cannot obtain the oil with SJ
or SH grade, you may use SG grade oil.) or the new
API mark (Starbrust mark) displayed on the container.

1 Indicates the oil quality by API designations
2 Indicates the SAE oil viscosity grade
3 Indicates that the oil has fuel saving capabilities
In choosing an oil, you want the proper quality and viscosity, as well as
one that will add to fuel economy. The following table lists the recom-
mended viscosities and applicable temperatures.
When adding oil, different brands may be used together as long as they
are the same API classification and SAE viscosity as those recom-
mended by SUBARU.
Engine oil viscosity (thickness) affects fuel economy. Oils of lower vis-
cosity provide better fuel economy. However, in hot weather, oil of higher
viscosity is required to properly lubricate the engine.
