TOP TIER Detergent Gasoline
Volvo endorses the use of "TOP TIER Deter-
gent Gasoline" where available to help main-
tain engine performance and reliability. TOP
TIER Detergent Gasoline meets a new stand-
ard jointly established by leading automotive
manufactures to meet the needs of today's
advanced engines. Qualifying gasoline retail-
ers (stations) will, in most cases, identify their
gasoline as having met the "TOP TIER Deter-
gent Gasoline" standards.

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 noticea-
ble.
Fuel Formulations

.
Do not use gasoline that contains lead or man-
ganese as a knock inhibitor, and do not use
lead additives. Besides damaging the exhaust
emission 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.
