pg. 60 Fuel requirements
Unleaded Fuel
Each Volvo has a catalytic converter and must use only unleaded gasoline (as specified on the
instrument panel and by a label near the filter inlet). U.S. and Canadian regulations require that pumps
delivering unleaded gasoline be labeled "UNLEADED". Only these pumps have nozzles which fit your
car's filler inlet. It is unlawful to dispense leaded fuel into a vehicle labelled "unleaded gasoline only".
Leaded gasoline damages the catalytic converter and the 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 inspection programs will make detection of misfueling easier,
possibly resulting in emission test failure for misfueled vehicles.
Octane Rating
Volvo recommends the use of premium unleaded gasoline with an (R+M)/2 rating of 91. This is
generally equivalent to a Research Octane Number (RON) of 95 or higher.
Deposit Control Gasolines
Volvo recommends the use of gasolines that contain "Deposit Control" additives. These additives are
specially formulated to prevent the build up of certain injector and intake system deposits. Fuels
containing "Deposit Control" additives are usually advertised as containing them and may have
additional claims to "clean injectors and intake valves" or similar wording.
