Fuel infor mation
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your SUBARU has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.
■ If your engine knocks
●Consult your SUBARU dealer.
● You may occasionally notice light knocking for a short time while acceler-
ating or driving uphill. This is normal and there is no need for concern.
■ Gasoline quality
In very few cases, driveability problems may be caused by the brand of gas-
oline you are using. If driveability problems persist, try changing the brand of
gasoline. If this does not correct the problem, consult your SUBARU dealer.
■ Fuel octane rating
Using a gasoline with a lower octane rating can cause persistent and heavy
knocking, which can damage the engine. Do not be concerned if your vehi-
cle sometimes knocks lightly when you drive up a hill or when you acceler-
ate. Contact your SUBARU dealer if you use a fuel with the specified octane
rating and your vehicle knocks heavily or persistently.
RON
This octane rating is the Research Octane Number.
AKI
This octane rating is the average of the Research Octane and Motor Octane
numbers and is commonly referred to as the Anti Knock Index (AKI). The engine is designed to operate at maximum performance using
unleaded gasoline with an octane rating of 93 AKI (98 RON) or
higher. If 93 AKI (98 RON) fuel is not readily available in your area,
unleaded gasoline with an octane rating of 91 AKI (95 RON) may be
used with no detriment to engine durability or driveability. However,
you may notice a slight decrease in maximum engine performance
and you may hear some knocking (pinging) from the engine while
using 91 AKI (95 RON) fuel. Use of 91 AKI (95 RON) fuel will not affect
your warranty coverage.

■
Reformulated Gasoline
SUBARU supports the use of reformulated gasoline when available.
Reformulated gasoline has been blended to burn more cleanly and reduce
vehicle emissions.
■ SUBARU recommends the use of gasoline containing detergent addi-
tives
● SUBARU recommends the use of gasoline that contains detergent addi-
tives to avoid build-up of engine deposits.
● All gasoline sold in the US contains detergent additives to clean and/or
keep clean intake systems.

CAUTION
■
Notice on fuel quality
● Do not use improper fuels. If improper fuels are used the engine and/or
fuel system will be damaged.
● Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s three-way catalytic
converters causing the emission control system to malfunction.
● Do not use gasohol other than that stated here.
Other gasohol may cause fuel system damage or vehicle performance
problems.
● Using unleaded gasoline with an octane number or rating lower than the
level previously stated will cause persistent heavy knocking.
At worst, this will lead to engine damage.
■ Fuel-related poor driveability
If after using a different type of fuel, poor driveability is encountered (poor
hot starting, vaporization, engine knocking, etc.), discontinue the use of that
type of fuel.
■ When refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle's paint.
