only those oils that  are  identified as meeting GM 
Standard  4718M  and  have  the Starburst symbol on the 
front  of the  oil container. 
Your  Corvette engine  is filled  at the factory  with a 
Mobil 
l@ synthetic  oil,  which meets all requirements 
for  your  vehicle. 
Substitute  Engine Oil: When adding oil  to maintain 
engine  oil level, oil  meeting GM Standard GM4718M 
may  not  be  available. You can add substitute oil 
designated  SAE 5W-30  with  the “Starburst” symbol at 
all  temperatures.  If temperatures are above 
0 OF (- 18 O C), 
you  may  substitute 
SAE low-30 with the “Starburst” 
symbol.  Substitute oil not meeting  GM Standard 
GM4718M  should  not  be used for an oil  change. 
Engine  Oil  Additives 
Don’t  add  anything  to  your  oil. Your  dealer is ready  to 
advise  if you  think  something should be added. 
When  to  Change  Engine  Oil 
Your Corvette  has  an  Engine Oil Life  Monitor. This 
feature  will  let  you  know  when to change your oil and 
filter 
-- usually  between 3,000 miles (5 000 km) and 
10,000  miles  (16 
000 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  10,000 miles (16 
000 km)  or 12 months 
(whichever occurs first)  without  an oil change.  Use 
engine  oil meeting the  GM Standard  GM47  18M. 
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 lun) or  sooner  if the  CHANGE  OIL 
light comes on. Remember  to  reset the Engine  Oil Life 
Monitor when the oil has been changed.  For more 
.information,  see “Engine Oil Life Monitor”  in the  Index. 
When  Changing  the  Engine  Oil 
There  is a special procedure  for changing  engine  oil, 
contact your dealer  for additional information  or  the 
procedure  can  be found in a Corvette  Service Manual. 
To  purchase a service manual, see  “Service and Owner 
Publications” in the Index. 
How to  Reset  the  Engine  Oil Life  Monitor 
Press RESET to acknowledge  the CHANGE  OIL SOON 
warning.  The oil page  will  then  show  a message  such  as 
OIL  LIFE 
0%. To reset the  monitor, press and hold 
RESET  for two seconds.  You will then  receive  a 
message such as OIL LIFE 
99%.

Downloaded from www.Manualslib.com manuals search engine 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. 
Air Cleaner 
Refer to the Maintenance  Schedule  to  determine  when  to 
replace the 
air filter. 
See “Scheduled Maintenance Services”  in  the  Index.   

Downloaded from www.Manualslib.com manuals search engine Change both the fluid and  filter every 50,000 miles 
(80 000 km) if  the  vehicle is mainly driven under  one of 
these conditions: 
In  heavy  city traffic  where  the  outside temperature 
regularly reaches 
90 OF (32 O C) or  higher. 
In hilly  or mountainous terrain. 
High  performance  operation. 
If  you  do not  use  your  vehicle under one of 
these  conditions. Change  the  fluid and filter  every 
100,000 miles (166 000 km). 
See “Scheduled Maintenance  Services”  in  the  Index  for 
the proper service intervals  for  the transmission  fluid 
and  filter. 
Manual  Transmission  Fluid 
When to Check 
How to Check 
Because  this  operation can  be difficult, you  may 
choose  to  have  this done  at your  Chevrolet  dealership 
Service  Department. 
If you do  it  yourself,  be  sure to follow  all  the 
instructions  here,  or  you could  get  a false  reading. 
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  exhaust  system  parts,  starting  a  fire.  Be  sure 
to 
get  an accurate  reading  if  you  check  your 
transmission  fluid. 
A good  time to have it checked  is when the  engine  oil 
is changed.  However, the fluid  in your  manual 
transmission doesn’t require  changing.  Check  the  fluid  level 
only when your  engine  is off, the 
vehicle 
is parked  on a level  place and  the  transmission is 
cool  enough  for  you to rest your  fingers on  the 
transmission  case.
