Fuel - Volvo S80 Owner's Manual

General information on fuel
Fuel of a lower quality than that recommended
by Volvo must not be used as engine power
and fuel consumption is negatively affected.
WARNING
Always avoid inhaling fuel fumes and fuel
splashing in the eyes.
If fuel gets into your eyes, take out contact
lenses if worn and rinse your eyes with
plenty of water for at least 15 minutes and
seek medical attention.
Never swallow fuel. Fuels such as petrol,
bioethanol and mixtures of the two, as well
as diesel, are highly toxic and could cause
permanent injury or be fatal if swallowed.
Seek medical attention immediately if fuel
has been swallowed.
WARNING
Fuel which spills onto the ground can be
ignited.
Switch off the fuel-driven heater before star-
ting to refuel.
Never carry an activated mobile phone
when refuelling. The ring signal could cause
spark build-up and ignite petrol fumes,
leading to fire and injury.
IMPORTANT
The use of other fuels for each respective
engine type, other than recommended here
by Volvo, could cause engine damage and
impaired performance.
The use of other fuels also invalidates Vol-
vo's warranties as well as any supplemen-
tary service agreement.
NOTE
Extreme weather conditions, driving with a
trailer or driving at high altitudes in combi-
nation with fuel grade are factors that could
affect the car's performance.
Petrol
Petrol must meet the EN 228 standard. Most
engines can be run with octane ratings of 95
and 98 RON. 91 RON should only be used in
exceptional cases.
•
95 RON can be used for normal driving.
•
98 RON is recommended for optimum per-
formance and minimum fuel consumption.
When driving in temperatures above +38 °C,
fuel with the highest possible octane rating is
recommended for optimum performance and
fuel economy.
05 During your journey
IMPORTANT
•
Always refuel with unleaded petrol so as
not to damage the catalytic converter.
•
In order that Volvo's warranty shall
remain valid, never mix alcohol with pet-
rol, as the fuel system could be dam-
aged.
•
Do not use additives not recommended
by Volvo.
Catalytic converters
The purpose of the catalytic converters is to
purify exhaust gases. They are located close to
the engine so that operating temperature is
reached quickly.
The catalytic converters consist of a monolith
(ceramic or metal) with channels. The channel
walls are lined with a thin layer of platinum/rho-
dium/palladium. These metals act as catalysts,
i.e. they participate in and accelerate a chem-
ical reaction without being used up them-
selves.
TM
Lambda-sond oxygen sensor
The Lambda-sond is part of a control system
intended to reduce emissions and improve fuel
economy.
An oxygen sensor monitors the oxygen content
of the exhaust gases leaving the engine. This
value is fed into an electronic system that con-
