1995 Oldsmobile Achieva fuel pump

Here are four things that some owners ask about. None
of these show a problem with your fuel gage:

It takes a little more or less fuel to fill up than the
the
gage reads
F (FULL).
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
the tank.
0 The gage moves a little when you turn a corner or
speed
up.
The gage doesn’t go back to E (EMPTY) when you
turn
off the ignition.

COOLANT
The LOW WASH
FLUID light will come
on when you turn on
the ignition, and the
fluid container is less
than one-third full.
Driving without washer fluid can be dangerous.
A bad
mud splash can block your vision. You could hit another
vehicle or
go off the road. Check your washer fluid level
often.

NOTICE:
If you try to do your own service work without
knowing enough about it, your vehicle could be
damaged.
Fuel
Use regular unleaded gasoline rated at 87 octane or
higher. It should meet specifications ASTM
D4814 in
the United States 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 United States 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.
