Fuel Requirements

Octane Rating
MINIMUM
Typical pump octane label
Volvo recommends premium fuel for best per-
formance, but using 87 octane
1
or above will
not affect engine reliability.
Volvo engines are designed to achieve rated
horsepower, torque, and fuel economy per-
formance using premium 91 octane fuel. In
demanding conditions, such as operating the
vehicle in hot weather, towing a trailer, or driv-
ing for extended periods at higher altitudes
than normal, it may be advisable to switch to
higher octane fuel (91 or higher) or to change
gasoline brands to fully utilize your engines
capacity, and for the smoothest possible op-
eration.
Fuel Formulations
Do not use gasoline that contains lead as a
knock inhibitor, and do not use lead additives.
Besides damaging the exhaust emission con-
trol systems on your vehicle, lead has been
strongly linked to certain forms of cancer.
Many fuels contain benzene as a solvent. Un-
burned 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 nozzle
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.
Deposit control gasoline (detergent
additives)
Volvo recommends the use of detergent gas-
oline to control engine deposits. Detergent
gasoline is effective in keeping injectors and

AKI (ANTI KNOCK INDEX) is an average of
the Research Octane Number (RON) and the
Motor Octane Number (MON), MON+RON/2.

NOTE
When switching to higher octane fuel or
changing gasoline brands, it may be neces-
sary to fill the tank more than once before a
difference in engine operation is noticeable.
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 ig-
nite gasoline fumes, resulting in fire and
injury.
WARNING
Carbon monoxide is a poisonous, colorless,
and odorless gas. It is present in all exhaust
gases. If you ever smell exhaust fumes in-
side the vehicle, make sure the passenger
compartment is ventilated, and immediately
return the vehicle to a trained and qualified
Volvo service technician for correction.
