!Alternative engine oil
If the SUBARU approved oil is unavailable, the following alternative oil can be used.NOTE.Each quantity indicated here is only a guideline. The necessary quantity for replacement may differ slightly depending on
the temperature and other factors.
.In choosing an oil, you want the proper quality and viscosity, as well as one that will enhance fuel economy. Oils of lower
viscosity provide better fuel economy. However, in hot weather, oil of higher viscosity is required to properly lubricate the
engine. The following table lists the recommended viscosities and applicable temperatures.
.When adding oil, you may use different brands together as long as they are the same API classification and SAE viscosity
as those recommended by SUBARU.

tute) classificationSNwith the
