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
• 15.9 US gal (60 liters, 13.2 Imp gal)
• 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.
• If you have recently fueled your vehicle, the check engine light on the instrument panel
may stay on due to a missing or loose fuel filler cap (the cap should be tightened until a
click is heard).
Fuel Filler Lid Release
The fuel filler lid release is located on the floor to the left of
the driver’s seat. To open the fuel filler lid, pull the fuel filler
lever up and release.
