NOTE - ENGINE OIL:
Although some oil consumption occurs 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 122-123.
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 refueled is one of
the most important items you can perform to help keep your car in good
running order.
Manual transmission
The following speeds should not be exceeded during the break-in
period:
Up to 600 miles 600 - 1,200 miles
(1000 km) (1000 - 2000 km)
1st gear 20 mph (30 km/h) 25 mph (40 km/h)
2nd gear 30 mph (50 km/h) 40 mph (70 km/h)
3rd gear 45 mph (80 km/h) 65 mph (100 km/h)
4th gear 70 mph (110 km/h) 80 mph (130 km/h)
5th gear 80 mph (130 km/h) 95 mph (150 km/h)
Posted speed limits should not be exceeded.
Fuel requirements
Deposit control (detergent) gasoline
Volvo recommends the use of detergent gasoline to control engine
deposits. Detergent gasoline is effective 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 labelled ”UNLEADED”. Only these
pumps have nozzles which fit your car’s filler inlet. It is unlawful to
dispense leaded fuel into a vehicle labelled ”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 methly-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.
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).
