NOTICE:
Fuel
The 8th digit of your Vehicle
Identification Number (VIN) shows
the code letter for your engine. You will
find the VIN at the top left of your
instrument panel. (See "Vehicle
Identification Number" in the Index.)
3.4L L32 (Code S)
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
In
the pump. And only unleaded nozzles
will fit into your vehicle's filler neck.
B e
sure the posted octane is at least 87.
:f the octane is less than
87, you
may get
sl
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.
