fuel pump BUICK REGAL 1993 Owners Manual

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
UNLEADEL,
FUEL
ONLY
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.
You need to get more right
away.
Here are
four concerns some owners have had about the
fuel gage. All these situations are normal and indicate
nothing wrong with the
fuel gage.
8 At the gas station, the gas pump shuts off before the
gage reads
“F”.
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.
e It takes more (or less) gas to fill up than the gage
e The gage moves a little when you turn a corner,
speed
up, or stop your vehicle.
When
you turn the engine off, the gage doesn’t go all
the
way back to “E”.

more fuel as soon
as you
can.

Fuel
Use regular unleaded gasoline rated at 87 octane or
higher. It should meet specifications ASTM D4814 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, 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.
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.
I
Gasolines for Cleaner Air
Your
use of gasoline with detergent 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.
Many gasolines are now blended with materials called
oxygenates. General Motors recommends that you use
