Engine oil

Adverse driving conditions
Check the oil level more frequently for long
journeys:
•
towing a caravan or trailer
•
in mountainous regions
•
at high speeds
11
•
in temperatures colder than -30 °C or hot-
ter than +40 °C.
This can produce abnormally high oil tempera-
ture or oil consumption.
Also check the oil level more often if the car is
often driven short distances (less than 10 km)
when temperatures are low (below +5 °C).
Choose a fully synthetic engine oil for adverse
driving conditions. It provides extra protection
for the engine.

Volvo recommends Castrol oil products.
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 inter-
vals can be applied. Only use a prescribed
grade of oil (see the engine compartment
decal) for both filling and oil change, other-
wise you will risk affecting service life, star-
ting characteristics, fuel consumption and
environmental impact.
Volvo Car Corporation disclaims all war-
ranty liability if engine oil of the prescribed
grade and viscosity is not used.
