SERVICE AND MAINTENANCE
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
methylcyclopentadienyl 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
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.
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.
Volvo allows the use of the following “oxygenated”
fuels; however, the octane ratings listed in your
owner’s manual 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
Fuels containing up to 15% MTBE may be used.
Engine oil
This vehicle comes from the factory with
synthetic oil.
Oil specificationsFull synthetic engine oil meeting the minimum RBS0-2AE/SAE 0W20 must be used. Lower
quality oils may not offer the same fuel economy,
engine performance, or engine protection.
Volvo recommends:
Oil additives must not be used.

SERVICE AND MAINTENANCE
Oil viscosity
Incorrect viscosity oil can shorten engine life under
normal use. SAE 0W-20 will provide good fuel
economy and engine protection.
Turbocharger Operating Tips
In order to maximize the efficiency and
operation of your vehicle, the following points
should be observed:
1. Oil change and filter replacement every
10,000 miles/16,000 km, or at a time interval
based on the type of driving and conditions as
detailed in your Owner’s Manual. You should
maintain a record of these services (repair
order receipts).
2. Do not use engine oil additives as they may
adversely affect the engine.
CAUTION
Never race the engine immediately after
starting. Oil flow may not reach some
lubricating points fast enough to prevent
turbocharger damage.
Before switching off the engine, let it operate
at idle for a short time to allow the spinning of
the turbocharger compressor’s turbine vanes to
slow. After hard driving, this idle time should last
a couple of minutes, during which the vanes will
slow and the compressor will cool down while
still receiving oil lubrication. If the turbine vanes
are spinning at high speeds when the engine is
switched off, there is a great risk of heat damage
and/or turbine seizure due to lack of lubrication. Do not race the engine just prior to switching
off!
