fuel pump PONTIAC PONTIAC 1995 Owners Manual

Fuel Gage Low Fuel Light
Your
fuel gage tells you
about how much fuel you
have left when the ignition
is on. When the indicator
nears
EMPTY (E), you still
have a little fuel left, but
you should get more soon.
Here are some things owners ask about. All these
situations are normal and
do not show a problem with
your fuel gage:
At the service station, the pump shuts off before the
gage
reads FULL (F).
It takes a little more or less fuel to fill up than the gage
indicated. For example, the gage may have indicated
the tank was half
full, but it actually took a little more
or less than half the tank’s capacity to fill it.
The gage moves a little when you turn a corner or
speed up. If
your fuel is low, a light
will come on and stay
on
until you add fuel. It will
also come on for
a few
seconds when you first turn
on the ignition as a check
to
show you it’s working. If it
doesn’t come on then, have
it fixed.

Fuel
Use regular unleaded gasoline rated at 87 octane or
higher.
It should meet specifications ASTM D4814 i.n
the United States and CGSB 3592 in Canada. These
hels should have the proper additives,
so you should not
have to add anything to the fuel.
h the United States and Canada, it’s easy to be sure you
get the right kind
of gasoline (unlea.ded). You.’ll see
UNLEADED right on the pump. And only unleaded
nozzles will fit into your vehicle’s filler neck.
Be sure the posted octane is
at least 87. If the octane is
less than
87, you may get a heavy knocking noise when
you drive. If it’s bad enough,
it can damage your engine.
Lf you’re using fuel rated at 87 octane or higher and you
still hear heavy hocking, your engine needs service.
But don’t
worry if you hear a little pinging noise when
you’re accelerating or driving up a hill. That’s normal,
and you dan’t have to buy a higher octane fuel to get rid
of pinmg. It’s the heavy, constant knock that means
you have a problem. What
about gasoline with blending materials that
contain oxygen (oxygenates), such
as MTBE or alcohol?
MTBE is “methyl tertiary-butyl ether.” Fuel that is no
more than
15% MTBE is fine for your vehicle.
Ethanol is ethyl or grain alcohol. Properly-blended fuel
that is no more than
10% ethanol is fine for your
vehicle.
Methanol is methyl or wood alcohol.
Fuel that is more than 5% methanol is bad for
your vehicle. Don’t use it. It can corrode metal parts
in your fuel system and also damage plastic
and rubber parts, That damage wouldn’t
be
covered under your warranty. And even at 5 % or
less, there must be “cosolvents’’ and corrosion
preventers
in this fuel to help avoid these
