STARTING AND DRIVING

Fuel Volvo recommends the use of detergent gaso- line to control engine deposits.
Deposit control gasoline (detergentadditives)
Detergent gasoline is effective in keeping injec- tors and intake valves clean. Consistent use ofdeposit control gasolines will help ensure gooddrivability and fuel economy. If you are not surewhether the gasoline contains deposit controladditives, check with the service station operator.
NOTE
Volvo does not recommend the use of exter- nal fuel injector cleaning systems.
Unleaded fuelEach Volvo has a three-way catalytic converter and must use only unleaded gasoline. U.S. andCanadian regulations require that pumps deliver-ing unleaded gasoline be labeled "UNLEADED".Only these pumps have nozzles which fit yourvehicle'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 oxygensensor system. Repeated use of leaded gasolinewill lessen the effectiveness of the emission con-trol system and could result in loss of emissionwarranty coverage. State and local vehicle inspection programs will make detection of mis-fueling easier, possibly resulting in emission testfailure 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 EmissionControl System performance may be affected,and the Check Engine Light (malfunctionindicator light) located on your instrumentpanel may light. If this occurs, please returnyour vehicle 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 laws requirethat the service pump be marked indicating useof alcohols or ethers. However, there are areas inwhich the pumps are unmarked. If you are notsure whether there is alcohol or ethers in thegasoline you buy, check with the service stationoperator. 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 listedmust still be met.
Alcohol – Ethanol
Fuels containing up to 10% ethanol by volume may be used. Ethanol may also be referred to asEthyl 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 practice canresult in vehicle performance deterioration andcan damage critical parts in the fuel system. Suchdamage may not be covered under the NewVehicle Limited Warranty.

Engine oil specifications and volume
Full synthetic engine oil meeting the minimum ACEA A5/B5 must be used. Lower quality oilsmay not offer the same fuel economy, engineperformance, or engine protection.
Volvo recommends:
Refer to the warranty and Service Records infor- mation booklet for information on oil changeintervals and oil type requirements.
NOTE
This vehicle comes from the factory with syn- thetic oil.
Oil additives must not be used.
Oil viscosityIncorrect viscosity oil can shorten engine life under normal use. SAE 5W-30 will provide goodfuel economy and engine protection. See the vis-cosity chart.
Viscosity chart
