1998 VOLVO S90 oil viscosity

1998 Volvo S90
A new car should be broken-in!

Refrain from utilizing your car's full driving
potential, e.g. full-throttle acceleration, during the
first 1,200 miles (2,000 km).

Automatic transmission

Do not use "kick-down" during the first 1,200
miles (2,000 km).

NOTE - ENGINE OIL:

Although some oil consumption during normal
engine operation, more oil is consumed when the
engine is new as the internal parts generate higher
friction while wearing-in to each other. From the
time the engine is new until the first service is
performed, the oil consumption could be
higher than normal. For this reason, it is
especially important to check the oil every time
you refuel your car during this period. See
page 108.
In general, the rate of oil consumption depends on
such factors as: engine temperature, length of trip,
driving conditions, oil viscosity and quality,
engine speed and acceleration/deceleration.
Checking your engine oil level each time the car
is refuelled is one of the most important items
you can perform to help keep your car in good
running order.

Deposit control gasoline (detergent
additives)

Volvo recommends the use of gasoline containing
deposit control additives. These additives have
shown to be efficient in keeping injectors and
intake valves clean. Consistent use of deposit
control gasolines will help ensure good
driveability and fuel economy. If you are not sure
whether the gasoline contains deposit control
additives, check with the service station operator.
Unleaded Fuel

Each Volvo has a three-way catalytic converter
and must use only unleaded gasoline. U.S. and
Canadian regulations require that pumps
delivering unleaded gasoline be labeled
"UNLEADED". Only these pumps have nozzles
which fit your car's filler inlet. It is unlawful to
dispense leaded fuel into a vehicle labeled
"unleaded gasoline only". Leaded gasoline
damages the three-way catalytic converter and the
heated oxygen sensor system. Repeated use of
leaded gasoline will lessen the effectiveness of
the emission control system and could result in
loss of emission warranty coverage. State and
local vehicle inspection programs will make
detection of misfueling easier, possibly resulting
in emission test failure for misfueled vehicles.

NOTE: Some U.S. and Canadian gasolines
contain an octane enhancing additive called
methyl-cyclopentadienyl manganese tricarbonyl
(MMT). If such fuels are used, your Emission
Control System performance may be affected,
and the Malfunction Indicator Lamp located on
your instrument panel may light. If this occurs,
please return your vehicle to an authorized Volvo
retailer for service.

Observe legal requirements of
the state in which the vehicles
are registered.
WARNING! Bumper-
attached trailer hitches must
not be used on Volvos, nor
should safety chains be
attached to the bumper.
Trailer hitches attaching to
the vehicle rear axle must
not be used. kgs) a top speed of 50 mph (80

subject to increased loads.
Therefore, engine coolant

watched when driving in hot

Winter driving pg. 69
Cold weather precautions
l If you wish to check your car before the
approach of cold weather, the following advice is
worth noting:
Make sure that the engine coolant contains at least
50 percent antifreeze: that is, 5.3 qts. (5 liters)
Volvo Genuine Coolant/Antifreeze. 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 types of antifreeze may not be
mixed.
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 fuel 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

l The Volvo Washer Solvent should be diluted as
follows:
Down to 14°F (-10°C): 1 part anti-freeze and 4
parts water
Down to 5°F (-15°C): 1 part anti-freeze and 3
parts water
Down to 0°F (-18°C): 1 part anti-freeze and 2
parts water
Down to -18°F (-28°): 1 part anti-freeze and 1
part water
l Use lock spray or grease in the locks.

NOTE: Avoid the use of de-icing spray as they
can cause damage to the locks.

Automatic differential lock (certain
models)


The differential automatically locks at speed
between 3 - 25 mph (5 - 40 km/h) if either of the
drive wheels begins to lose traction. The
differential lock improves power distribution to
the drive wheels in slippery conditions, shifting
power to the wheel with best traction. It also

If you change the engine oil and filter
yourself, your Volvo retailer can assist you
in disposing of the used oil. Engine oil can
be harmful to your skin - gloves should
worn when performing this work.

Oil quality

Meeting API specification SG, SG/CD, SH or
Energy Conserving (EC) II
For best fuel economy and engine protection
consult with your authorized Volvo retailer for
recommended oils. Oils with a different quality
rating may not provide adequate engine
protection.

Viscosity (stable ambient
temperatures):




Do not use oils with other viscosity ratings. The
use of incorrect viscosity oil can shorten engine
life.
Volvo recommends the use of energy-conserving
oils. Look for the API label. Synthetic oils
complying with oil quality requirements are
recommended for: driving in areas of sustained
temperature extremes (hot or cold), when towing
a trailer over long distances or for prolonged
driving in mountainous areas.
Extra oil additives must not be used unless
advised by an authorized Volvo retailer.

NOTE: SAE 15W/40 should only be used in


Changing oil and oil filter

Oil and oil filter changes should be made as
specified in the following table:

If driving conditions
include: Then the correct oil/oil
filter change interval
is:
l Extended periods of
idling and/or low-
speeds operation
l Frequent short trips
(less than 7 miles = 11
km)
l Extended periods of
driving in dusty and/or
sandy areas
l Trailer towing
l Driving in
mountainous areas EVERY 6 MONTHS
OR EVERY
5,000 miles= 8,000 km

l Frequent trips of
longer than 7 miles =
11 km EVERY 12 MONTHS
