Octane rating
Minimum octane
G028920
Typical pump octane label
Volvo recommends premium fuel for best
performance, but using 87 octane
1
or above
will not affect engine reliability.
Demanding driving
In demanding driving conditions, such as
operating the vehicle in hot weather, towing a
trailer, or driving for extended periods at
higher altitudes than normal, it may be advis-
able to switch to higher octane fuel (91 or
higher) or to change gasoline brands to fully
utilize your engine's capacity, and for the
smoothest possible operation.
NOTE
When switching to higher octane fuel or
changing gasoline brands, it may be nec-
essary to fill the tank more than once
before a difference in engine operation is
noticeable.
Fuel Formulations
Do not use gasoline that contains lead as a
knock inhibitor, and do not use lead addi-
tives. Besides damaging the exhaust emis-
sion control systems on your vehicle, lead
has been strongly linked to certain forms of
cancer.
Many fuels contain benzene as a solvent.
Unburned benzene has been strongly linked
to certain forms of cancer. If you live in an
area where you must fill your own gas tank,
take precautions. These may include:
standing upwind away from the filler noz-
zle while refueling
refueling only at gas stations with vapor
recovery systems that fully seal the
mouth of the filler neck during refueling
wearing neoprene gloves while handling a
fuel filler nozzle.
Use of Additives
With the exception of gas line antifreeze dur-
ing winter months, do not add solvents, thick-
eners, or other store-bought additives to your
vehicle's fuel, cooling, or lubricating systems.
Overuse may damage your engine, and some
of these additives contain organically volatile
chemicals. Do not needlessly expose yourself
to these chemicals.
WARNING
Never carry a cell phone that is switched
on while refueling your vehicle. If the
phone rings, this may cause a spark that
could ignite gasoline fumes, resulting in
fire and injury.
WARNING
Carbon monoxide is a poisonous, color-
less, and odorless gas. It is present in all
exhaust gases. If you ever smell exhaust
fumes inside the vehicle, make sure the
passenger compartment is ventilated, and
immediately return the vehicle to a trained
and qualified Volvo service technician for
correction.
