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.

line is available at www.toptiergas.com.
Demanding driving
In demanding driving conditions, such as operat-
ing the vehicle in hot weather, towing a trailer, or
driving 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 engine's
capacity, and for the smoothest possible opera-
tion.
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.
