Additional Information

Fuel
• For WRX, use premium unleaded gasoline with an octane rating of 91 AKI or higher. If
91 AKI fuel is not readily available, regular unleaded gasoline with an octane rating of 87
AKI or higher may be temporarily used. However, depending on your driving habits and
conditions, you may notice a decrease in engine performance, fuel economy and slight
engine vibration or knocking. Consult the Owner's Manual for more detailed information.
• For WRX STI, use premium unleaded gasoline with an octane rating of 93 AKI or higher.
If 93 AKI fuel is not readily available in your area, premium unleaded gasoline with an
octane rating of 91 AKI may be used with no detriment to engine durability or driveability.
However, you may notice a slight decrease in maximum engine performance while using
91 AKI fuel. Consult the Owner's Manual for more detailed information.
Fuel Capacity

• When the low fuel indicator light is displayed on the instrument panel, approximately 2.6
US gallons (10.0 liters, or 2.2 Imp gal) of fuel remain.
