TOP TIER Detergent Gasoline
Volvo endorses the use of “TOP TIER Detergent
Gasoline” where available to help maintain engine
performance and reliability. TOP TIER Detergent
Gasoline meets a new standard jointly estab-
lished by leading automotive manufactures to
meet the needs of today’s advanced engines.
Qualifying gasoline retailers (stations) will, in
most cases, identify their gasoline as having met
the “TOP TIER Detergent Gasoline” standards.
NOTE
Information about TOP TIER Detergent Gaso-
line is available at www.toptiergas.com.
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.
Fuel Formulations
Do not use gasoline that contains lead 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 pre-
cautions. 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.
