Adverse driving conditions for engine oil
Check the oil level more frequently for long journeys:
- towing a caravan or trailer
- in mountainous regions
- at high speeds
- in temperatures colder than -30 °C (-22 °F) or hotter than +40 °C (+104 °F).
The above also applies to shorter driving distances at low temperatures.
Choose a fully synthetic engine oil for adverse driving conditions. It provides extra protection for the engine.
Volvo recommends:
Important
- In order to fulfil the requirements for the engine’s service intervals, all engines are filled with 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.
- 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, there is a risk of the service life, starting characteristics, fuel consumption and environmental impact of the car is affected.
- If engine oil of the prescribed grade and viscosity is not used, engine-related components may become damaged. Volvo disclaims any liability for any such damage.
- Volvo recommends that oil changes are carried out at an authorised Volvo workshop.
