When driving under adverse conditions, see Engine oil - adverse driving conditions.
Important
In order to fulfil the requirements for the engine's service intervals all engines are filled with a specially adapted synthetic engine oil at the factory. The choice of oil has been made very carefully with regard to service life, starting characteristics, fuel consumption and environmental impact.
An approved engine oil must be used in order that the recommended service intervals can be applied. Only use a prescribed grade of oil for both filling and oil change, otherwise you will risk affecting service life, starting characteristics, fuel consumption and environmental impact.
Volvo Car Corporation disclaims all warranty liability if engine oil of the prescribed grade and viscosity is not used.
Volvo recommends that oil changes are carried out at an authorised Volvo workshop.
Volvo uses different systems for warning of low/high oil level or low oil pressure. Certain engine variants have an oil pressure sensor, and then the combined instrument panel's warning symbol for low oil pressure is used. Other variants have an oil level sensor, when the driver is informed via the instrument's warning symbol 
and display texts. Certain variants have both systems. Contact a Volvo dealer for more information.
Change the engine oil and oil filter in accordance with the intervals specified in the Service and Warranty Booklet.
Using oil of a higher than specified grade is permitted. If the car is driven in adverse conditions, Volvo recommends using an oil of a higher grade; see Engine oil - adverse driving conditions.
For filling capacities, see Engine oil - grade and volume.
