2003 VOLVO XC70 oil viscosity

2003 VOLVO XC70
Cold weather precautions
If you wish to check your car before the approach of cold weather, the f\
ollowing advice is worth noting:
l Make sure that the engine coolant contains 50 percent antifreeze. Any ot\
her mixture will reduce
freeze protection. This gives protection against freezing down to -31°\
F (-35°C). See section "Coolant".
The use of "recycled" antifreeze is not approved by Volvo. Different typ\
es of antifreeze must not
be mixed.
l Volvo recommends using only genuine Volvo antifreeze in your car's radia\
tor. Your local Volvo
retailer stocks plenty of Volvo engine coolant to protect your car durin\
g cold weather.
l Try to keep the fuel tank well filled - this prevents the formation of condensation in the tank. \
In
addition, in extremely cold weather conditions it is worthwhile to add f\
uel line de-icer before refueling.
l The viscosity of the engine oil is important. Oil with low viscosity (thinner oil) improves cold-
weather starting as well as decreasing fuel consumption while the engine\
is warming up. For winter use,
5W-30 oil, particularly the synthetic type *, is recommended. Be sure to\
use good quality oil but do not
use this cold-weather oil for hard driving or in warm weather. See section "Engine oil" for more
information.
l The load placed on the battery is greater during the winter since the windshield wipers, lighting, etc\
.
are used more often. Moreover, the capacity of the battery decreases as \
the temperature drops. In very
cold weather, a poorly charged battery can freeze and be damaged. It is \
therefore advisable to check the
state of charge more frequently and spray an anti-rust oil on the batter\
y posts.
l Volvo recommends the use of snow tires on all four wheels for winter dri\
ving - see section "Wheels
and tires".
l To prevent the washer fluid reservoir from freezing, add washer solvents\
containing antifreeze (see
page 130 for the location of the washer fluid reservoir). This is important sin\
ce dirt is often splashed on
the windshield during winter driving, requiring the frequent use of the \
washers and wipers. The Volvo
Washer Solvent should be diluted as follows:
Down to 14° F (-10° C): 1 part washer solvent and 4 parts water \
Down to 5° F (-15° C): 1 part washer solvent and 3 parts water
Down to 0° F (-18° C): 1 part washer solvent and 2 parts water
Down to -18° F (-28° C): 1 part washer solvent and 1 part water \
l Use Volvo Teflon Lock Spray in the locks.
NOTE: Avoid the use of de-icing sprays as they can cause damage to the locks.
W Winter/Wet driving mode - enhanced vehicle traction
l Mode W will only function if the gear selector is in the (D)rive posit\
ion.
l Press the button at the base of the gear selector to engage/disengage th\
is driving mode (see
illustration).
l An LED in the button will light up to indicate that W is engaged and this will also be displayed in the
instrument panel (see
page 27).
l This mode may be selected for starting/moving off on slippery roads.

Volvo Cars recommends Castrol.
Depending on your driving habits, premium or synthetic oils may provide \
superior fuel economy and
engine protection. Consult your Volvo retailer for recommendations on pr\
emium or synthetic oils.
Oil additives must not be used.
NOTE: Synthetic oil is not used when the oil is changed at the normal maintena\
nce services. This oil is
only used at customer request, at additional charge. Please consult your\
Volvo retailer.
Oil viscosity (stable ambient temperatures)
Operation in temperate climates
Incorrect viscosity oil can shorten engine life. Under normal use when t\
emperatures do not exceed 86 °F
(30°C), SAE 5W/30 will provide good fuel economy and engine protect\
ion. See the viscosity chart
below.
Operation in hot climates
When temperatures exceed 86 °F (30°C) in your area, Volvo recomm\
ends, for the protection of your
engine, that you use a heavier weight oil, such as SAE 10W/30. See the v\
iscosity chart below.
Extreme engine operation
Synthetic oils meeting SAE 10W/30 and complying with oil quality require\
ments 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.
Changing oil and oil filter
Oil and oil filter changes should be made at 7,500 mile (12,000 km) in\
tervals.

The API Service Symbol "donut" is divided into three parts:

l The top half describes the oil's performance level.
l The center identifies the oil's viscosity.
l The bottom half tells whether the oil has demonstrated energy-conserving\
proper ties in a standard
test in comparison to a reference oil.
Viscosity (stable ambient temperatures)

Break-in Period
Although some oil consumption occurs during normal engine operation, mor\
e oil is consumed when the
engine is new as the internal parts generate higher friction while weari\
ng-in each other. From the time
the engine is new until the first service is performed, the oil consumpt\
ion could be higher than
normal. For this reason, it is especially important to check the oil eve\
ry time you refuel you car
during this period.

pg. 136 Engine oil
Checking the oil level
The oil level should be checked every time the car is refueled. This is \
especially important during
the period up to the first service.
CAUTION:
Not checking the oil level regularly can result in serious engine damage\
if the oil level becomes too low.
Park the car on a level surface and wait for at least 5 minutes after th\
e engine has been switched off. Be
sure the oil level is maintained between the upper and lower marks on th\
e dipstick. Low oil level can
damage the engine. Overfilling can result in high oil consumption and da\
mage the emissions system.
The distance between the dipstick marks represents approx. 1.6 US qt (1\
.5 liter). The oil should
preferably be checked when cold, before the engine has been started.
