Volvo XC90: Starting and driving / Fuel

Volvo recommends the use of detergent gasoline to control engine deposits.

Deposit control gasoline (gasoline with detergent additives)

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.

NOTE

Volvo recommends not using external fuel injector cleaning systems, e.g. do not add detergent additives to gasoline before or after refueling.

Unleaded fuel

All Volvo vehicles have a three-way catalytic converter and must only use unleaded gasoline. US and Canadian regulations require that pumps delivering unleaded gasoline are labeled "UNLEADED". Only the nozzles of these pumps will fit in your vehicle's fuel filler inlet. It is unlawful to dispense leaded fuel into a vehicle labeled "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 inspection 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 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 permits the use of the following "oxygenated" fuels. However, the specified octane ratings 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/ETBE: Fuels containing up to 22% MTBE/ETBE by volume 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.

    Refueling

    The fuel tank is equipped with a fuel filling system without a cover. Refueling the vehicle at a service station It is important to insert the pump's nozzle past both of the two flaps in the fuel filler pipe before beginning fueling...

    Octane rating

    Volvo requires premium fuel (91 octane1 or higher) for all T5, T6 and T8 engines, and recommends AKI 93 for optimal performance and fuel economy. See decal examples in illustrations 1 and 2...

      Connecting equipment to the vehicle's data link connector

      Incorrectly connected or installed software or diagnostic tools may have an adverse effect on the vehicle's electronics.

      We strongly recommend that Volvo owners use only genuine, Volvo-approved accessories, and that accessory installations be performed only by a trained and qualified Volvo service technician. Certain accessories only work when the associated software is installed in the vehicle's computer system.
