Engine Oil - Volvo S40 Owner's Manual

Adverse driving conditions
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 or
hotter than +40 °C.
This can produce abnormally high oil temper-
ature 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 en-
gine'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 consump-
tion 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, start-
ing characteristics, fuel consumption and
environmental impact.
Volvo Car Corporation disclaims all warran-
ty liability if engine oil of the prescribed
grade and viscosity is not used.
