In choosing an oil, you want the proper quality and
viscosity, as well as one that will add to fuel econo-
my. The following table lists the recommended vis-
cosities and applicable temperatures.
When adding oil, different brands may be used to-
gether as long as they are the same API classifica-
tion and SAE viscosity as those recommended by
SUBARU.
Engine oil viscosity (thickness) affects fuel economy.
Oils of lower viscosity provide better fuel economy.
However, in hot weather, oil of higher viscosity is re-
quired to properly lubricate the engine.
