1995 CHEVROLET CORVETTE fuel

Downloaded from www.Manualslib.com manuals search engine Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
~ battery charged. You will need a well-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlights. Let the heater run for awhile.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it as little as possible. Preserve the
fuel as long as you can. To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or
so until help comes.

Two labels on your vehicle show how much weight it
may properly carry. The Tire-Loading Information label
found on the driver’s door tells you the proper size,
speed rating and recommended inflation. It also gives
you important information about the number of people
that can be in your vehicle and the total weight that you
can carry.
This weight is called Vehicle Capacity Weight
and includes the weight of all occupants, cargo, and all
nonfactory-installed options.

The other label is the Certification label, found on the
rear edge of the driver’s door. It tells you the gross
weight capacity of your vehicle, called the GVWR
(Gross Vehicle Weight Rating). The GVWR includes the
weight of the vehicle, all occupants, fuel and cargo.
Never exceed the GVWR for your vehicle, or the Gross
Axle Weight Rating (GAWR) for either the front
or rear
axle.
And,
if you do have a heavy load, you should spread it
out. Don’t carry more than
100 pounds (45 kg) in your
rear area.

Here you will find information about the care of your
Corvette. This section begins with service and fuel
information, and then it shows how to check important
fluid and lubricant levels. There is also technical
information about your vehicle, and a part devoted to its
appearance care.
Service
Your Chevrolet 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
service people.

Doing Your Own Service Work
If you want to do some of your own service work, you’ll
want to get the proper Corvette Service
Manual. It tells
you much more about how to service your Corvette than
this manual can.
To order the proper service manual, see
“Service Publications’’ in the Index.

Downloaded from www.Manualslib.com manuals search engine Your vehicle has an air bag system. Before attempting to
do your own service work, see “Servicing Your Air
Bag-Equipped Corvette” in the Index.
You ;should keep a record with all parts receipts and list
the mileage and the date of any service work you
perform. See “Maintenance Record” in the Index.
NOTICE:
If you try to do your own service work without
knowing enough about it, your vehicle could be
damaged.
Fuel
5.7L LT5 (Code J) Engine
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.)
Use premium unleaded gasoline rated at
9 1 octane or
higher. You may use middle grade or regular unleaded
gasolines, but your vehicle may not accelerate as well.
The gasoline you use 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.

Downloaded from www.Manualslib.com manuals search engine Be sure the posted octane is at least 91. If the octane is
less than 91, you may get a heavy knocking noise when
you drive. (In an emergency,
you may be able to use
lower octane
-- as low as 87 -- if heavy knocking does
not occur.)
If you’re using 91 or higher octane unleaded
gas and you still get heavy knocking, your engine needs
service.
What about gasoline with blending materials that
contain oxygen (oxygenates), 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.
i Wethanol is methyl or wood alcohol.
NOTICE:
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 these
problems.

Downloaded from www.Manualslib.com manuals search engine Gasolines for Cleaner Air
Your use of gasoline with deposit control 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 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 deposit control additives and
oxygenates, and if they have been reformulated to
reduce vehicle emissions.
5.7L LT1 (Code P) Engine
Use premium unleaded gasoline rated at 91 octane or
higher
for best performance. You may use middle grade
or regular unleaded gasolines, but your vehicle may not
accelerate as well. The gasoline you use 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 for premium
is at least 91 (at
least
89 for middle grade and 87 for regular). 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 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 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.

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.
You can also write us at the following address for
advice. Just tell
us where you’re going and give your
Vehicle Identification Number (VIN).
