Octane rating
: Volvo engines are designed for optimum performance
on unleaded premium gasoline with an octane rating AKI of 91, or
above. AKI (ANTI KNOCK INDEX) is an average of the Research
Octane Number, RON, and the Motor Octane Number, MON. (RON +
MON/2). The minimum octane requirement is AKI 87 (RON 91).
Deposit control gasoline (detergent additives)
Volvo recommends the use of detergent gasoline to control engine
deposits. Detergent gasoline is effective in keeping injectors and intake
valves clean. Consistent use of deposit control gasolines will help
ensure good driveability and fuel economy. If you are not sure whether
the gasoline contains deposit control additives, check with the service
station operator.
Unleaded fuel
Each Volvo has a three-way catalytic converter and must use only
unleaded gasoline. U.S. and Canadian regulations require that pumps
delivering unleaded gasoline be labelled UNLEADED. Only these
pumps have nozzles which fit your cars filler inlet. It is unlawful to
dispense leaded fuel into a vehicle labelled unleaded gasoline 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 control system and could result
in loss of emission warranty coverage. State and local vehicle inspec-
tion programs will make detection of misfueling 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 lamp)
located on your instrument panel may light. If this occurs, please return
your vehicle to an authorized Volvo retailer 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 oxygenated fuels; however, the
octane ratings listed on this page 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.
CAUTION!
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.
