1998 VOLVO S90 fuel additives

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.

NOTE: Do not add additives yourself to the
gasoline, unless you are recommended to do so
by an authorized Volvo retailer.

Octane Rating

Volvo engines are designed for
optimum performance on
unleaded premium gasoline
with an octane rating, AKI of
91, or above. AKI (ANTI
KNOCK INDEX) is an average
of the Research Octane
Number, RON, and the Motor
Octane Number, MON, (RON
+ MON/ 2).
The minimum octane
requirement is AKI 87 (RON
91).

Gasoline Containing
Alcohol and Ethers

"Oxygenated fuels"
Some fuel suppliers sell
gasoline containing
"oxygenates" which are usually
alcohols or ethers. In some
areas, state or local laws
require that the service pump
be marked indicating use of
alcohol or ethers. However,
there are areas in which the
pumps are unmarked. If you are
not sure whether there is
alcohol or ethers in the gasoline
you buy, check with the service
station operator. To meet
seasonal air quality restrictions,
some states require the use of
"oxygenated" fuel in certain
areas.
Alcohol -- Ethanol
Fuels containing up to 10%
ethanol by volume may be
used.
Ethanol may also be referred to
as Ethyl alcohol, or "Gasohol".
Ethers -- MTBE
Fuels containing up to 15%
MTBE may be used.

Refueling

The fuel tank filler cap is
located behind the door on the
left rear fender. Open cap
slowly during hot weather
conditions.
When filling, position the cap
in the special bracket on the
door.
After filling the tank, install the
cap and turn until a "click" is
heard.
The fuel tank is designed to
hold approximately 21.1 US
gals (80 liters) with sufficient
volume left over to
accommodate possible
expansion of the fuel in hot
weather. The "usable" capacity
is 20.3 US gallons (77 liters).
When the fuel level is low,
such factors as ambient
temperature, the fuel's "vapor
pressure" characteristics, and
terrain can affect the fuel
pumps' ability to supply the
engine with an adequate supply CAUTION:
l Avoid spilling gasoline during
refueling. Gasolines containing
alcohol can cause damage to
painted surfaces, which may not
be covered under the New
Vehicle Limited Warranty.
l Do not use gasoline
containing methanol (methyl
alcohol, wood alcohol). This
practice can result in vehicle
performance deterioration and
can damage critical parts in the
fuel system. Such damage may
not be covered under the New
Vehicle Limited Warranty.
l Allow for fuel expansion by
not overfilling the tank.
Overfilling could also cause
damage to the emission control
systems.

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
WHICHEVER

l Primarily highway
driving
l Frequent trips of
longer than 7 miles =
11 km EVERY 12 MONTHS
OR EVERY
10,000 miles = 16,000
