Oil quality
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 specifications 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 maintenance services. This oil is
only used at customer request, at additional charge. Please consult your Volvo retailer.
Oil viscosity (stable ambient temperatures)
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
below.
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 below.
Extreme engine operation
Synthetic oils meeting SAE 10W-30 and complying with oil quality requirements are recommended for
