Refueling – fuel requirements
Volvo recommends the use of detergent gas- oline to control engine deposits.
Deposit control gasoline (detergentadditives)
Detergent gasoline is effective in keepinginjectors and intake valves clean. Consistentuse of deposit control gasolines will helpensure good drivability and fuel economy. Ifyou are not sure whether the gasoline con-tains deposit control additives, check with theservice station operator.
NOTE
Volvo does not recommend the use of external fuel injector cleaning systems.
Unleaded fuelEach Volvo has a three-way catalytic con- verter and must use only unleaded gasoline.U.S. and Canadian regulations require thatpumps delivering unleaded gasoline belabeled "UNLEADED". Only these pumpshave nozzles which fit your vehicle's fillerinlet. It is unlawful to dispense leaded fuelinto a vehicle labeled "unleaded gasolineonly". Leaded gasoline damages the three-way catalytic converter and the heated oxy-gen sensor system. Repeated use of leadedgasoline will lessen the effectiveness of theemission control system (p. 265) and could result in loss of emission warranty coverage.State and local vehicle inspection programswill 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 calledmethyl-cyclopentadienyl manganese tri-carbonyl (MMT). If such fuels are used,your Emission Control System perform-ance may be affected, and the CheckEngine Light (malfunction indicator light)located on your instrument panel maylight. If this occurs, please return yourvehicle to a trained and qualified Volvoservice technician for service.
Gasoline containing alcohol and ethers, "Oxygenated fuels"
Some fuel suppliers sell gasoline containing "oxygenates" which are usually alcohols orethers. In some areas, state or local lawsrequire that the service pump be marked indi-cating use of alcohols or ethers. However,there are areas in which the pumps areunmarked. If you are not sure whether there isalcohol or ethers in the gasoline you buy,check with the service station operator. Tomeet seasonal air quality standards, someareas require the use of "oxygenated" fuel.
Volvo allows the use of the following "oxy-genated" fuels; however, the octane rat-ings (p. 262) listed must still be met.
Alcohol – EthanolFuels 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.
MethanolDo not use gasolines containing methanol(methyl alcohol, wood alcohol). This practicecan result in vehicle performance deteriora-tion and can damage critical parts in the fuelsystem. Such damage may not be coveredunder the New Vehicle Limited Warranty.

Refueling – octane rating
Volvo recommends premium fuel for best per- formance, but using 87 octane11
or above will
not affect engine reliability.
Minimum octane
G028920
Typical pump octane label
NOTE
Vehicles equipped with the high perform- ance 4-cylinder engines (B4204T9 and B4204T10) require premium fuel 12

TOP TIER Detergent GasolineVolvo endorses the use of “TOP TIER Deter- gent Gasoline” where available to help main-tain engine performance and reliability. TOPTIER Detergent Gasoline meets a new stand- ard jointly established by leading automotivemanufactures to meet the needs of today’sadvanced engines. Qualifying gasoline retail-ers (stations) will, in most cases, identify theirgasoline as having met the “TOP TIER Deter-gent Gasoline” standards.
NOTE
Information about TOP TIER Detergent Gasoline is available atwww.toptiergas.com.
Demanding drivingIn demanding driving conditions, such as operating the vehicle in hot weather, towing atrailer, or driving for extended periods athigher altitudes than normal, it may be advis-able to switch to higher octane fuel (91 orhigher) or to change gasoline brands to fullyutilize your engine's capacity, and for thesmoothest possible operation.
NOTE
When switching to higher octane fuel or changing gasoline brands, it may be nec-essary to fill the tank more than oncebefore a difference in engine operation isnoticeable.
Fuel FormulationsDo not use gasoline that contains lead as a knock inhibitor, and do not use lead addi-tives. Besides damaging the exhaust emis-sion control systems on your vehicle, leadhas been strongly linked to certain forms ofcancer. Many fuels contain benzene as a solvent. Unburned benzene has been strongly linkedto certain forms of cancer. If you live in anarea where you must fill your own gas tank,take precautions. These may include:
• standing upwind away from the filler noz- zle while refueling
• refueling only at gas stations with vaporrecovery systems that fully seal themouth of the filler neck during refueling
• wearing neoprene gloves while handling afuel filler nozzle.
Use of AdditivesWith the exception of gas line antifreeze dur- ing winter months, do not add solvents, thick-eners, or other store-bought additives to yourvehicle's fuel, cooling, or lubricating systems.Overuse may damage your engine, and someof these additives contain organically volatilechemicals. Do not needlessly expose yourselfto these chemicals.
