B
Gasoline for California-certified LEV
Your vehicle was certified to California’s low emission vehicle (LEV)
standards as indicated on the underhood tune-up label. It is designed
to optimize engine and emission control system performance with
gasoline that meets the clean burning low-sulfur California gasoline
specifications. If you live in any other state than California, your ve-
hicle will operate on gasoline meeting Federal specifications. Gaso-
line sold outside California is permitted to have higher sulfur levels,
which may affect the performance of your vehicle’s catalytic converter
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
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. 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.
