octane CHEVROLET LUMINA 1993 1.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine I 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 hock that means you have a
problem.
Fuel Capacity:
V6 Engines-16.5 U.S. Gallons (62 L).
L4 Engine--17.1 U.S. Gallons (65 L).
Use unleaded fuel only.
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.
I NOTEE
Fuel that is more than 5
methanol is bad for you
Don’t use it. It can corr
parts in your fuel system
and also
damage plastic and rubber parts.
That damage wouldn’t be covered
under your warranty. 5% or less, there mus
“cosolvents” and corrosi
