Your General Motors dealer knows your vehicle best and wants you to\
be
happy with it. We hope you’ll go to your dealer for all your service needs.
You’ll get genuine GM parts and GM-trained and supported ser\
vice people.
We hope you’ll want
to keep your GM vehicle all GM. GM parts have one of
these marks:
Doing Your Own Service Work
If you want to do some of your own service work, you’ll want to get the
proper General Motors Service Manual. It tells you much more a\
bout how to
service your vehicle than this manual can.
To order the proper service
manual, see “Service Publications” in the Index.
You should keep
a record with all parts receipts and list the mileage and
date of any service work you perform. See “Maintenance Record” \
in the
Index.
Yolu can be injured
if you try to do service work on a vehicle without
knowing enou’glh about it.
9 Be sure you have sufficient know18edge, experience, and the
proper replacement parts and tools before you attempt any
vehicle maintenance
task.
@~ Be sure to use th’e proper nuts, bolts and other fasteners.
“English” and “metric” fasEeners can be easily confused.
If you
use the wrong fasteners, parts can later break ‘ar fall
off. You
could be hurt.

Fuel
6-4

Downloaded from www.Manualslib.com manuals search engine If you’re using fuel rated at 91 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 nor\
mal, 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.
-uel that is more than
5% methanol is bad for your vehicle. Don’t use il
’ an corrode metal parts in your fuel system and also damage plastic
ma rubber parts. That damage wouldn’t be covered under your Wa-
Znd even at
5% or less, there must be “cosolvent! “ and corrosion
Ireventers
in this fuel to help avoid these problem! 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 gasolines with these blending ma\
terials,
such as MTBE and ethanol. By doing
so, you can help clean the air,
especially in those parts
of the country that have high carbon monoxide
levels.
In addition, some gasoline suppliers are now producing reformulated \
gasolines. These gasolines are specially designed to reduce vehicle
emissions. General Motors recommends that you use reformulated g\
asoline. By doing
so, you can help clean the air, especially in those parts of the
country that have high ozone levels.
You should ask your service station operators
if their gasolines contain
detergents and oxygenates, and
if they have been reformulated to reduce
vehicle emissions.

Fuels in Foreign Countries
If you plan on driving in another country outside the US. or Canada,
unleaded fuel may be hard
to find. Do not use leaded gasoline. If you use
even one tankful, your emission controls won’t work well or at all. With
continuous use, spark plugs can get fouled, the exhaust system \
can corrode,
and your engine oil can deteriorate quickly. Your vehicle’s three-way catalytic
converter and oxygen sensor will be damaged.
All of that means costly
repairs that wouldn’t be covered by your warranty.
To check on fuel availability, ask an auto club, or contact a major oil
company that does business in the country where you’ll be d\
riving.
You can also write us at the following address for advice.
Just tell us where
you’re going and give your Vehicle Identification Number (VI\
N).

Filling Your Tank
A Gasoline vapor is highly flammable. It burns violently, and that can
cause very bad injuries. Don’t smoke if you’re near g’asoline or
aefuel’ing your vehicle. Keep sparks, flames, and smoking mat\
erials
away fmm gasoline.
