Engine oilAlthough 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 wearingin 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 period.
See page 191 for more information.Fuel requirementsDeposit control gasoline (detergent
additives)Volvo recommends the use of detergent gas-
oline 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 driva-
bility and fuel economy. If you are not sure
whether the gasoline contains deposit control
additives, check with the service station oper-
ator.
NOTE
Volvo does not recommend the use of
external fuel injector cleaning systems.
Unleaded fuelEach Volvo has a three-way catalytic converter
and must use only unleaded gasoline. U.S. and
Canadian regulations require that pumps deliv-
ering unleaded gasoline be labelled "UNLEA-
DED". Only these pumps have nozzles which
fit your vehicle's filler inlet. It is unlawful to dis-
pense 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 effec-
tiveness of the emission control system and
could result in loss of emission warranty cov-
erage. State and local vehicle inspection pro-
grams 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 affec-
ted, and the Check Engine Light (malfunc-
tion indicator lamp) located on your instru-
ment 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 indi-
cating 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 sea-
sonal 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 listed
on this page 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 "Gaso-
hol".
Ethers – MTBE: Fuels containing up to 15%
MTBE may be used.

121 Octane rating
Minimum octane
G028920
Typical pump octane labelVolvo recommends premium for best perform-
ance, but using 87 octane or above will not
affect engine reliability.
Volvo engines are designed to achieve rated
horsepower, torque, and fuel economy per-
formance using premium 91 octane fuel.Demanding drivingIn demanding driving conditions, such as oper-
ating the vehicle in hot weather, towing a trailer,
or driving for extended periods at higher alti-
tudes than normal, it may be advisable to
switch to higher octane fuel (91 or higher) or to
change gasoline brands to fully utilize yourengine's capacity, and for the smoothest pos-
sible operation.
NOTE
When switching to higher octane fuel or
changing gasoline brands, it may be neces-
sary to fill the tank more than once before a
difference in engine operation is noticeable.Fuel FormulationsDo not use gasoline that contains lead as a
knock inhibitor, and do not use lead additives.
Besides damaging the exhaust emission con-
trol systems on your vehicle, lead has been
strongly linked to certain forms of cancer.
Many fuels contain benzene as a solvent.
Unburned benzene has been strongly linked to
certain forms of cancer. If you live in an area
where you must fill your own gas tank, take
precautions. These may include:•
standing upwind away from the filler nozzle
while refueling
•
refueling only at gas stations with vapor
recovery systems that fully seal the mouth
of the filler neck during refueling
•
wearing neoprene gloves while handling a
fuel filler nozzle.
Use of AdditivesWith the exception of gas line antifreeze during
winter months, do not add solvents, thicken-
ers, or other store-bought additives to your
vehicle's fuel, cooling, or lubricating systems.
Overuse may damage your engine, and some
of these additives contain organically volatile
chemicals. Do not needlessly expose yourself
to these chemicals.

09 Maintenance and servicingEngine oil
09190
Oil specificationsEngine oil must meet the minimum ILSAC
specification GF-4, API SL, or ACEA A1/B1.
Lower quality oils may not offer the same fuel
economy, engine performance, or engine pro-
tection.
Volvo recommends Castrol.
Depending on your driving habits, premium or
synthetic oils may provide superior fuel econ-
omy and engine protection. Consult your Volvo
retailer or a trained and qualified Volvo service
technician for recommendations on premium
or synthetic oils.Oil additives must not be used.
NOTE
Synthetic oil is not used when the oil is
changed at the normal maintenance serv-
ices. This oil is only used at customer
request, at additional charge. Please con-
sult a trained and qualified Volvo service
technician.
Oil viscosity (stable ambient
temperatures)Operation in hot climatesWhen temperatures exceed 104° F (40° C) in
your area, Volvo recommends, for the protec-
tion of your engine, that you use a heavier
weight oil, such as such as SAE 5W-40 or
0W-40. See the viscosity chart.
G023491
Operation in temperate climatesIncorrect viscosity oil can shorten engine life.
Under normal use when temperatures do not
exceed 104° F (40° C), SAE 5W-30 will provide
good fuel economy and engine protection. See
the viscosity chart.Extreme engine operationSynthetic oils meeting SAE 0W-30 or 0W-40
and complying with oil quality requirements arerecommended for driving in areas of sustained
temperature extremes (hot or cold), when tow-
ing a trailer over long distances, and for pro-
longed driving in mountainous areas.
G022917
American Petroleum Institute (API) symbolAmerican Petroleum Institute (API)
symbolThe API Service Symbol "donut" is divided into
three parts:•
The upper section describes the oil's per-
formance level.
•
The center identifies the oil's viscosity.
•
The lower section indicates whether the oil
has demonstrated energy-conserving
properties in a standard test in comparison
to a reference oil.

NOTE
Volvo uses different systems to indicate a
low oil level or pressure. Some models have
an oil pressure sensor, in which case a
warning symbol (see page 52) is used to
indicate low oil pressure. Other models have
an oil level sensor, in which case the driver
is alerted by the warning symbol in the cen-
ter of the instrument panel and a text in the
information display. Some models use both
systems. Contact a trained and qualified
Volvo service technician for more informa-
tion.Changing engine oil and oil filterSee the information on oil specifications above
and page 240 for oil volumes. Refer to the
Warranty and Service Records Information
booklet for information on the oil change inter-
vals.
NOTE
•
Volvo does not recommend the use of
oil additives.
•
Synthetic oil is not used when the oil is
changed at the normal maintenance
intervals except at owner request and at
additional charge. Please consult a
trained and qualified Volvo service tech-
nician.
Checking and adding oilThe oil level should be checked every time the
vehicle is refueled. This is especially important
during the period up to the first scheduled
maintenance service.•
The vehicle should be parked on a level
surface when the oil is checked.
•
If the engine is warm, wait for at least
10-15 minutes after the engine has been
switched off before checking the oil.
Checking the oil
G020336
1. Pull out the dipstick and wipe it with a lint-
free rag.2. Reinsert the dipstick, pull it out, and check
the oil level.
3. Add oil if necessary. If the level is close to
theMINmark, add approximately
1 US quart (1 liter) of oil.
4. Run the engine until it reaches normal
operating temperature.
5. Switch off the engine and wait for at least
10-15 minutes and recheck the oil level. If
necessary, add oil until the level is near the
MAX mark.
CAUTION
•
Not checking the oil level regularly can
result in serious engine damage if the oil
level becomes too low.
•
Never fill oil above the MAX mark. This
could cause an increase in oil consump-
tion.
•
Not checking the oil level regularly can
result in serious engine damage if the oil
level becomes too low.
•
Always add oil of the same type and
viscosity as already used.WARNING
Do not allow oil to spill onto or come into
contact with hot exhaust pipe surfaces.
