Ethanol is ethyl or grain alcohol. Properly-blended fuel
that is no more than
10% ethanol is fine for your car.
Methanol is methyl or wood alcohol.
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
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 materials, 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 gasoline. 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
U.S. 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 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 driving.

90 OF (32 “C) or
higher.

12.
Supercharger Oil Check -- Check oil every 30,000
miles (50 000 km) or 36 months. Add the proper
synthetic
oil. S.ee “Recommended Fluid and
Lubricants’’ in the Index.
* An Emission Control Service.
? The U.S. Environmental Protection Agency has determined that the failure to perform this maintenance item will not nullify the emission warranty or limit recall liability prior to the completion of vehicle
useful life. General Motors, however, urges that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded in ‘‘Section E:Maintenance Record’‘.
