06 Maintenance and specifications
Specifications
Engine oil
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.
Volvo recommends
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.
Synthetic oil is not used when the oil is
changed at the normal maintenance ser-
vices. This oil is only used at customer
request, at additional charge. Please consult
06
your Volvo retailer.
Oil viscosity (stable ambient tempera-
tures)
Operation in hot climates
When temperatures exceed 86° F (30° C) in
your area, Volvo recommends, for the pro-
tection of your engine, that you use a heavier
weight oil, such as such as SAE 5W-40 or
0W-40. See the viscosity chart.

oil products.
Viscosity table
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 0W-30 or 0W-40
and complying with oil quality requirements
are recommended for driving in areas of sus-
tained temperature extremes (hot or cold),
when towing a trailer over long distances,
and for prolonged driving in mountainous
areas.

symbol
The API Service Symbol "donut" is divided
into three parts:
• The upper section describes the oil's per-
formance 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 compari-
son to a reference oil.
