Recommended Grade And Viscosity Under Severe Driving Conditions - Subaru FORESTER Manual

11-18
Maintenance and service
In choosing an oil, you want the proper
quality and viscosity, as well as one that
will add to fuel economy. The following
tables list the recommended 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 recommended by SUBARU.
2.0 L models
SAE viscosity No. and applicable tempera-
ture
*: 0W-20 is recommended.
2.5 L models
SAE viscosity No. and applicable tempera-
ture
*: 5W-30 is recommended.
Engine oil viscosity (thickness) affects 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.
CAUTION
Use only engine oil with the recom-
mended grade and viscosity.
& Recommended grade and
viscosity under severe driv-
ing conditions
If the vehicle is used in desert areas, in
areas with very high temperatures, or
used for heavy-duty applications such as
towing a trailer, use of oil with the following
grade and viscosities is recommended.
API classification SM or SL:
SAE viscosity No.:
30, 40, 10W-50, 20W-40, 20W-50
