Volvo 2006 S60 - Manual (Page 102)

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
driving in mountainous areas.

The API Service Symbol "donut" is divided into three parts:
The upper section describes the oilÕs performance level.

Changing engine oil and oil filter
See the previous page for oil specifications and
page 168 for oil volumes. Refer to the Warranty and Service Records
Information booklet for information on the oil change intervals.
NOTE:
Volvo does not recommend the use of oil additives.
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 your Volvo retailer.
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.
