and may produce a sulfur exhaust odor or smell. SUBARU recom-
mends that you try a different brand of unleaded gasoline having low-
er sulfur to determine if the problem is fuel related before returning
your vehicle to an authorized dealer for service.
B Gasoline for cleaner air
Your use of gasoline with detergent additives will help prevent depos-
its from forming in your engine and fuel system. This helps keep your
engine in tune and your emission control system working properly,
and is a way of doing your part for cleaner air. If you continuously use
a high quality fuel with the proper detergent and other additives, you
should never need to add any fuel system cleaning agents to your
fuel tank.
Many gasolines are now blended with materials called oxygenates.
Use of these fuels can also help keep the air cleaner. Oxygenated
blend fuels, such as MTBE (Methyl Tertiary Butyl ether) or ethanol
(ethyl or grain alcohol) may be used in your vehicle, but should con-
tain no more than 15% MTBE or 10% ethanol for the proper operation
of your SUBARU.
In addition, some gasoline suppliers are now producing reformulated
gasoline, which is designed to reduce vehicle emissions. SUBARU
approves the use of reformulated gasoline.
If you are not sure what the fuel contains, you should ask your service
station operators if their gasoline contains detergents and oxygenates
and if they have been reformulated to reduce vehicle emissions.
As additional guidance, only use fuels suited for your vehicle as ex-
plained below.
D Fuel should be unleaded and have an octane rating no lower than
that specified in this manual.
D Methanol (methyl or wood alcohol) is sometimes mixed with un-
leaded gasoline. Methanol can be used in your vehicle ONLY if it
does not exceed 5% of the fuel mixture AND if it is accompanied by
sufficient quantities of the proper cosolvent and corrosion inhibitors
required to prevent damage to the fuel system. Do not use fuel con-
