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 mountainous areas, or if the vehicle is often
driven short distances in temperatures under 40°F (5°C).

Engine oil
Oil specifications
Engine oil must meet the minimum ILSAC specification GF-3, API SL, or ACEA A1/B1. Lower quality oils may not
offer the same fuel economy, engine performance, or engine protection.
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 liters).
Volvo recommends Castrol.
Depending on your driving habits, premium or synthetic oils may provide superior fuel economy 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 viscosity (stable ambient temperatures)
Operation in hot climates
When temperatures exceed 104° F (40° C) in your area, Volvo recommends, for the protection of your engine, that you
use a heavier weight oil, such as such as SAE 5W -40 or 0W -40. See the viscosity chart.
Operation in temperate climates
Incorrect 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 operation
Synthetic 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 towing a trailer over long distances, and for
prolonged driving in mountainous areas.

American Petroleum Institute (API) symbol
The API Service Symbol "donut" is divided into three parts:
The upper section describes the oil's performance 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.

Engine specifications
1The engine specifications for horsepower and torque listed in this table are based on the use of premium fuel.
Charge air cooler (Intercooler)
Turbocharged engines employ a turbo-compressor to force air into the engine inlet manifold and a charge air cooler to
cool the compressed inlet air. The resulting increase in air flow raises pressure in the intake manifold and increases

engine power over that developed by the normally-aspirated engine. The charge air cooler (which resembles a radiator)
is located between the turbo-compressor and inlet manifold.
Fuel system
The engine is equipped with a multiport fuel injection system.

Three-way catalytic converter - general information
Keep your engine properly tuned. Certain engine malfunctions, particularly involving the electrical, fuel or
distributor ignition systems, may cause unusually high three-way catalytic converter temperatures. Do not continue to
operate your vehicle if you detect engine misfire, noticeable loss of power or other unusual operating conditions, such
as engine overheating or backfiring. A properly tuned engine will help avoid malfunctions that could damage the three-
way catalytic converter.
Do not park your vehicle over combustible materials, such as grass or leaves, which can come into contact with the
hot exhaust system and cause such materials to ignite under certain wind and weather conditions.
Excessive starter cranking (in excess of one minute), or an intermittently firing or flooded engine can cause three-
way catalytic converter or exhaust system overheating.
Remember that tampering or unauthorized modifications to the engine, the Electronic Control Module, or the vehicle
may be illegal and can cause three-way catalytic converter or exhaust system overheating.
This includes:
- Altering fuel injection settings or components.
- Altering emission system components or location or removing components.
- Repeated use of leaded fuel.
NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
