1994 BUICK REGAL fuel pump

When one of the warning lights comes on and stays on
when you are driving, or
when one of the gages shows
there may be a problem, check the section that tells you
what to do about
it. Please follow the manual’s advice.
Waiting to do repairs can be costly
-- and even
dangerous.
So please get to know your warning lights
and gages. They’re a big help.
Fuel Gage
Your fuel gage shows about
how much fuel is
in your
tank.
It works only when
the engine is on. When the
indicator nears
“E,” you
still have a little fuel left. Here
are some concerns owners have had about the fuel
gage. All these situations are normal and indicate
nothing wrong
with the fuel gage.

At the gas station, the gas pump shuts off before the
gage reads
“F”.
It takes more (or less) gas to fill up than the gage
indicated. For example, the gage indicated 1/2
full,
but it took more -- or less -- than half of the tank’s
capacity to
fill it.
The gage moves a little when you turn a corner,
speed
up, or stop your vehicle.
When you turn the engine off, the gage d&sn’t go all
the way back to
“E”.

Fuel
Use regular unleaded gasoline rated at 87 octane or
higher. It should meet specifications ASTM
D48 14 in
the U.S. and CGSB 3.5-92 in Canada. These fuels
should have the proper additives,
so you should not have
to add anything to the fuel.
In the
U.S. and Canada, it’s easy to be sure you get the
right kind of gasoline (unleaded).
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.
If you’re using fuel rated at 87 octane or higher and you
still hear heavy knocking, 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 don’t have
to buy a higher octane fuel to get rid
of pinging. 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.
I NOTICE:
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 problems.
Gasolines for Cleaner Air
Your use of gasoline with deposit control additives will
help prevent deposits from forming in your engine and
fuel system. That helps keep your engine
in tune and
your emission control system working properly. It’s
good for your vehicle, and you’ll be doing your part for
cleaner air.
