2007 Volvo V70
Although some oil consumption occurs during normal engine operation, more oil is consumed when the
engine is new as the internal parts generate higher friction while wearing-in to each other. From the time
the engine is new until the first service is performed, the oil consumption could be higher than normal.
For this reason, it is especially important to check the oil every time you refuel your vehicle during this
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.
NOTE: Volvo does not recommend the use of external fuel injector cleaning systems.
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 vehicle's 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 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 lamp) located on your
instrument panel may light. If this occurs, please return your vehicle to an authorized Volvo retailer for
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.
