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 driving in mountainous areas.
