REPLACEMENT
FASTENERS
During
car
maintenance, any fasteners used to replace older ones must
have the same measurements and strength as those removed, whether.
metric or customary. (The numbers on the heads
of
metric bolts and on
the surfaces·
of
metric nuts show their strength.
Customary
bolts use
radial lines to show this, while
most
customary nuts do not have strength
markings.) Fasteners taken from the
Car
should be saved for re-use in the
same
spot
when possible. Where a fastener cannot be used again, care
should be taken to choose
a replacement
that
matches the old one. For
information
and
help, see your Pontiac dealer.
MAINTENANCE SCHEDULE

which contains a complete maintenance schedule.
It
also briefly describes
the safety, emission control, lubrication, and general service
that
your car
requires.
The Maintenance Schedule folderis supplemented by this section
of
the
Owner's Manual, as well as a
Warranty
Information folder also
furnished with your car. Read
all three publications for a full
understanding
of
your car's maintenance needs.
FUEL REQUIREMENTS .
Your
gasoline engine
is
designed to use only unleaded gasoline. Unleaded
gasoline must be used for proper ernission control system operation. Its
use will also minimize spark plug fouling
and
extend
engine oil life. Using
leaded gasoline can damage the emission control system and could result
in
loss of emission warranty coverage.
Use unleaded gasoline meeting Federal Government regulations.
The
Federal Government specifies the minimum octane number
of
unleaded
gasoline. Federal regulations require
that
pumps delivering such gasoline
be labeled with the word
unleaded. Only these pumps
are
equipped with
delivery nozzles
whichfit
the
filler neck
of
your
car's
gasoline tank.
