STARTING AND DRIVING
365
Fuel
Volvo recommends the use of detergent gaso-
line to control engine deposits.
Deposit control gasoline (detergent
additives)
Detergent gasoline is effective in keeping injec-
tors 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 contains deposit control
additives, check with the service station operator.
NOTE
Volvo does not recommend the use of exter-
nal fuel injector cleaning systems.
Unleaded fuel
Each Volvo has a three-way catalytic converter
and must use only unleaded gasoline. U.S. and
Canadian regulations require that pumps deliver-
ing unleaded gasoline be labeled "UNLEADED".
Only these pumps have nozzles which fit your
vehicle's filler inlet. It is unlawful to dispense lea-
ded fuel into a vehicle labeled "unleaded gaso-
line only". Leaded gasoline damages the three-
way catalytic converter and the heated oxygen
sensor system. Repeated use of leaded gasoline
will lessen the effectiveness of the emission con-
trol system and could result in loss of emission
warranty coverage. State and local vehicle
inspection programs will make detection of mis-
fueling easier, possibly resulting in emission test
failure for misfueled vehicles.
NOTE
Some U.S. and Canadian gasolines contain an
octane enhancing additive called methyl-
cyclopentadienyl manganese tricarbonyl
(MMT). If such fuels are used, your Emission
Control System performance 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 indicating 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.
Volvo allows the use of the following "oxygen-
ated" fuels; however, the octane ratings listed
must still be met.
Alcohol – Ethanol
Fuels containing up to 10% ethanol by volume
may be used. Ethanol may also be referred 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 deterioration and
can damage critical parts in the fuel system. Such
damage may not be covered under the New
Vehicle Limited Warranty.
