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 technician.
Checking and adding oil
The 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 car 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
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 the MIN mark, 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.
NOTE
Not checking the oil level regularly can result in serious engine damage if the oil level becomes too low.
Oil that is lower than the specified quality can damage the engine.
Always add oil of the same type and viscosity as already used.
Never fill oil above the MAX mark. This could cause an increase in oil consumption.

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.
