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.
