If any one of these is true for you, use the short tripkity
maintenance schedule:
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
Driving under these conditions causes engine oil to break
down sooner.
If any one of these is true for your vehicle,
you need to change your oil and filter every
3,000 miles
(5 OOO km) or 3 months -- whichever occurs first.
If none of them is true, use the long triphighway
maintenance schedule. Change the oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever
occurs first. Driving a vehicle with a fully warmed
engine under highway conditions causes engine oil to
break down slower.
Your Corvette has an Oil Life Monitor. This featwe will
let you know when to change your
oil and filter -- usually
between
3,000 miles (5 O00 krn) and 7,500 miles
(12
500 km) since your last oil change. Under severe
conditions, the indicator may come on before
3,000 miles
(5 000 km). Never drive your vehicle more than
7,500 miles (12 500 km) or 12 months (whichever
occurs first) without
an oil change.
The system won’t detect dust in the oil.
So, if you
drive in a dusty area, be sure to change your oil every
3,000 miles
(5 000 km) or sooner if the CHANGE OIL
light comes on. Remember to reset the monitor when the
oil has been changed. For more information, see
“Engine Oil Life Monitor”
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\

When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change both the fluid and filter every
15,000 miles
(25 000 km) if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic where the outside temperature
In hilly or mountainous terrain.
Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, change the fluid and filter at
100,000 miles
(166 000 km).
See “Scheduled Maintenance Services” in the Index.
How to Check
Because this operation can be a little difficult, you
may choose to have this done at your Corvette
dealership Service Department.
regularly
reaches 90
OF (32 O C) or higher.
If you do it yourself, be sure to follow all the instructions
here, or you could get
a false reading on the dipstick.
I NOTICE:
Too much or too little fluid can damage your
transmission.
Too much can mean that some of
the fluid could come out and fall on hot engine
parts or exhaust system parts, starting a fire. Be
sure to get an accurate reading if you check your
transmission fluid.
Wait at least 30 minutes before checking the
transmission fluid level if you have been driving:
0 When outside temperatures are above 90°F (32°C).
0 At high speed for quite a while.
In heavy traffic -- especially in hot weather.
To get the right reading, the fluid should be at normal
operating temperature, which is
180°F to 200°F
(82°C to 93°C).
