Engine oil
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
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
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 at
right.
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 at right.
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 driving in mountainous areas.
The API Service Symbol
The API Service Symbol “donut” is divided
into three parts:
• The top half describes the oil’s performan
ce level.
• The center identifies the oil’s viscosity.
• The bottom half tells whether the oil has
demonstrated energy-conserving
proper ties in a standard test in
comparison to a reference oil.

Changing oil and oil filter
Oil and oil filter changes should be made at 7,500 mile (12,000 km)
intervals.
