result in loss of emission warranty coverage.
State and local vehicle inspection programs
will make detection of misfueling easier, pos-
sibly resulting in emission test failure for mis-
fueled vehicles.
NOTE
Some U.S. and Canadian gasolines con-
tain an octane enhancing additive called
methyl-cyclopentadienyl manganese tri-
carbonyl (MMT). If such fuels are used,
your Emission Control System perform-
ance may be affected, and the Check
Engine Light (malfunction indicator light)
located on your instrument panel may
light. If this occurs, please return your
vehicle to a trained and qualified Volvo
service technician for service.
Gasoline containing alcohol and ethers,
"Oxygenated fuels"
Some fuel suppliers sell gasoline containing
"oxygenates" which are usually alcohols or
ethers. In some areas, state or local laws
require that the service pump be marked indi-
cating use of alcohols or ethers. However,
there are areas in which the pumps are
unmarked. If you are not sure whether there is
alcohol or ethers in the gasoline you buy,
check with the service station operator. To
meet seasonal air quality standards, some
08
areas require the use of "oxygenated" fuel.
11 AKI (ANTI KNOCK INDEX) is an average of the Research Octane Number (RON) and the Motor Octane Number (MON), MON+RON/2.
Refer to your Warranty and Maintenance Records booklet for additional information.

270
Volvo allows the use of the following "oxy-
genated" fuels; however, the octane rat-
ings (p. 270) listed must still be met.
Alcohol – Ethanol
Fuels containing up to 10% ethanol by vol-
ume may be used. Ethanol may also be refer-
red to as Ethyl alcohol, or "Gasohol".
Ethers – MTBE: Fuels containing up to
15% MTBE may be used.
Methanol
Do not use gasolines containing methanol
(methyl alcohol, wood alcohol). This practice
can result in vehicle performance deteriora-
tion and can damage critical parts in the fuel
system. Such damage may not be covered
under the New Vehicle Limited Warranty.
Refueling – octane rating
Volvo recommends premium fuel for best per-
formance, but using 87 octane 11
not affect engine reliability.

NOTE
Vehicles equipped with the high perform-
ance 4-cylinder engines (B4204T9 and
B4204T10) require premium fuel
TOP TIER Detergent Gasoline
Volvo endorses the use of "TOP TIER Deter-
