Your engine is designed to work with
the electronics in your vehicle. If you
add electrical parts or accessories,
you could change the way the fuel
injection system operates. Before
adding electrical equipment, check
with your dealer. If you don’t, your
engine might not perform properly.
If you ever have to have your vehicle
towed, see the part
of this manual
that tells how to do it without
damaging your vehicle. See “Towing
Your Vehicle” in the Index.
Engine Power Switch (ZR-I)
The LT5 engine in your ZR-1 has two sets
of intake runners and fuel injectors. The
primary set can be run alone for normal
engine power, or both sets can be used
for
full engine power.
Full power gives you extra power for
highway touring and off-road sports use
and reserve power for passing. With
normal power, you’ll notice less engine
and exhaust noise. To
change the power setting, put your
engine power key into the switch. Turn
the key to the setting you want and let
go
The key will return to the center position.
Your ZR-1 is able to run at full power
under the following conditions:
The engine coolant and oil
temperatures are greater than
68 OF
(20°C) but less than 302°F (150°C).
e System voltage is greater than ten
e The “SERVICE ENGINE SOON’
volts.
light is not on.
You can switch the setting at engine
speeds up to
4,000 rpm. When you
select the
“FULL” setting, a light near
[he switch will come on. It should go
>ut when you change back to the
“NORMAL” setting. When you turn the
ignition
off, the setting will go back to
normal power.
Off-Road Track Use
See your Warranty Book before using
your Corvette for off-road track use.
NOTICE:
If you use your Corvette for off-road
track use, your engine may use more
oil than it would with normal use.
Low oil levels can damage the
engine. Be sure to check the oil level
often during off-road track use.
You
may need to add additional oil. See
“Engine Oil” in the Index.

oil to maintain engine oil level, if an oil
meeting GM Standard GM4718M is not
available, you can use oil designated
either
SAE 5W-30 API Service SH or SG
at all temperatures, or
SAE 1OW-30 API
Service
SH or SG at temperatures above
0°F (-18°C). This oil should not be used
for an oil change.
Substitute Oil (LT5 Only): When adding
oil to maintain engine oil level, if an oil
meeting
GM Standard GM4718M is not
available, you can use oil designated SAE
1OW-30 API Service SH or
SG at all
temperatures. This oil should not be used
for an oil change.
Engine Oil Additives
Don’t add anything to your oil. Your
Chevrolet dealer is ready to advise if you
think something should be added.
When to Change Engine Oil
See if any one of these is true for you:
Most trips are less than 4 miles
It’s below freezing outside and most
trips are less than
10 miles (16 km).
(6 km).
The engine is at low speed most of
the time (as
in stop-and-go traffic).
Most trips are through dusty places.
If any one of these is true for your
vehicle, you need to change your oil and
filter every 3,000 miles
(5 000 km) or
3 months
- whichever comes first.
(See “Engine Oil Life Monitor” in the
Index.)
If none of them is true, change the oil
every 7,500 miles
( 12 500 km) or 12
months
- whichever comes first. Change
the filter at the first oil change and at
every other oil change after that. (See
“Engine Oil Life Monitor” in the Index.)
Engine Coolant Heater (Engine Block
Heater)
An engine coolant heater can be a big
help if you have to park outside in very
cold weather,
0 “F (- 18 “C) or colder. If
your vehicle has this feature, see “Engine
Coolant Heater” in the Index.
What to Do with Used Oil
Did you know that used engine oil
contains certain elements that may be
unhealthy for your skin and could even
cause cancer? Don’t let used oil stay on your
skin for very long. Clean your skin
and nails with soap and water, or a good
hand cleaner. Wash or throw away
clothing or rags containing used engine
oil. (See the manufacturer’s warnings
about the use and disposal of oil
products.)
Used oil can be a real threat to the
environment. If you change your own oil,
be sure to drain all free-flowing oil from
the filter before disposal. Don’t ever
dispose of oil by putting it in the trash,
pouring it on the ground, into sewers, or
into streams or bodies of water. Instead,
recycle
it by taking it to a place that
collects used oil. If you have a problem
properly disposing of your used oil, ask
your dealer, a service station or
a local
recycling center for help. L 1
