NOTE
The transmission oil does not normally need
to be changed during the service life of the
vehicle. However, it may be necessary to
replace the oil if the vehicle is often driven
in areas of sustained temperature extremes
(hot or cold), when towing a trailer over long
distances, for prolonged driving in moun-
tainous areas, or if the vehicle is often driven
short distances in temperatures under 40 °F
(5 °C).
Oil specifications
Engine 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.
Volume: 6.1 US qts (5.8 liters).
Volume between the MIN and MAX marks on
the dipstick: approximately 1.4 US qts (1.3 lit-
ers).
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 service intervals.
This oil is only used at customer request, at
additional charge. Please consult a trained
and qualified Volvo service technician.
Oil viscosityIncorrect viscosity oil can shorten engine life
under normal use. SAE 5W-30 will provide
good fuel economy and engine protection. See
the viscosity chart.
G023491
Viscosity chart
Extreme engine operationSynthetic oils meeting SAE 0W-30 or 0W-40
and complying with oil quality requirements are
recommended 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.
American Petroleum Institute (API)
symbol
G022917
The 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.

Charge air cooler (Intercooler)
The engine employs a turbo-compressor to
force air into the engine intake manifold and a
charge air cooler to cool the compressed inletair. The resulting increase in air flow raises
pressure in the intake manifold and increases
engine power over that developed by the nor-
mally-aspirated engine. The charge air cooler(which resembles a radiator) is located
between the turbo-compressor and intake
manifold.
