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.
Volvo allows the use of the following "oxy-
genated" fuels; however, the octane rat-
ings (p. 277) listed must still be met.
Refueling – fuel requirements
Volvo recommends the use of detergent gas-
oline to control engine deposits.
Alcohol – Ethanol
Deposit control gasoline (detergent
additives)
Fuels containing up to 10% ethanol by vol-
ume may be used. Ethanol may also be refer-
red to as Ethyl alcohol, or "Gasohol".
Detergent gasoline is effective in keeping
injectors and intake valves clean. Consistent
use of deposit control gasolines will help
ensure good drivability and fuel economy. If
you are not sure whether the gasoline con-
tains deposit control additives, check with the
service station operator.
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.
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.
NOTE
Volvo does not recommend the use of
external fuel injector cleaning systems.
Gasoline containing alcohol and ethers,
"Oxygenated fuels"
Unleaded fuel
Each Volvo has a three-way catalytic con-
verter and must use only unleaded gasoline.
U.S. and Canadian regulations require that
pumps delivering unleaded gasoline be
labeled "UNLEADED". Only these pumps
have nozzles which fit your vehicle's filler
inlet. It is unlawful to dispense leaded fuel
into a vehicle labeled "unleaded gasoline
only". Leaded gasoline damages the three-
way catalytic converter and the heated oxy-
gen sensor system. Repeated use of leaded
gasoline will lessen the effectiveness of the
emission control system (p. 280) and could
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
areas require the use of "oxygenated" fuel.
