Oil specifications
Engine oil must meet the minimum ILSAC specification GF-2, including ACEA A1, API SJ, SJ/CF and SJ/Energy
Conserving. Your Volvo has been certified to standards using ILSAC oil specification GF-2 5W-30. Volvo
recommends use of oil with a quality rating equal to or higher than ILSAC GF-2. Equivalent and better oils include
ACEA A1, API SJ, SJ/CF, and SJ/Energy conserving. Lower quality oils may not offer the same fuel economy, engine
performance, or engine protection.
Volvo Cars recommends Castrol.
Depending on your driving habits, premium or synthetic oils may provide superior fuel economy and engine
protection. Consult your Volvo retailer 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 your Volvo retailer.
Oil viscosity (stable ambient temperatures)
Operation in hot climates
When temperatures exceed 86° F (30° C) in your area, Volvo recommends, for the protection of your engine, that you
use a heavier weight oil, such as SAE 10W-30. See the viscosity chart.
Operation in temperate climates
Incorrect viscosity oil can shorten engine life. Under normal use when temperatures do not exceed 86° F (30° C), SAE
5W-30 will provide good fuel economy and engine protection. See the viscosity chart.
Extreme engine operation
Synthetic oils meeting SAE 10W-30 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
