B Unleaded gasoline
The neck of the fuel filler pipe is designed to accept only an unleaded
gasoline filler nozzle. Under no circumstances should leaded gaso-
line be used because it will damage the emission control system and
may impair driveability and fuel economy.
B Gasoline for California-certified LEV
If your vehicle is a California-certified Low Emission Vehicle (LEV) as
indicated on the underhood tune-up label, it is designed to optimize
engine and emission control system performance with gasoline that
meets California low sulfur specifications. Your vehicle will operate on
gasoline meeting Federal specifications.
B Gasoline for cleaner air
CAUTION
Do not let fuel spill on the exterior surfaces of the vehicle. Fuels
containing alcohol may cause paint damage, which is not cov-
ered under the SUBARU Limited Warranty.
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. SUBARU ap-
proves the use of oxygenated blend fuels, such as MTBE (Methyl Ter-
tiary Butyl Ether) or ethanol (ethyl or grain alcohol). The blended fuels
should contain no more than 15% MTBE or 10% ethanol for the proper
operation of your SUBARU.
In addition, some gasoline suppliers are now producing reformulated
gasolines, which are designed to reduce vehicle emissions. SUBARU
approves the use of reformulated gasoline.
