NOTICE: 
If  you  keep  driving  your  vehicle  with  this  light 
on,  after  a  while  the  emission  controls  won’t 
work  as  well,  your  fuel  economy  won’t  be  as  good 
and  your  engine  may  not  run as smoothly.  This 
could  lead  to  costly  repairs  not  covered  by  your 
warranty.

This  light will  come 
on  briefly  when  you 
are  starting the engine. 
If  it stays  on,  or  if 
it 
comes  on and stays on 
while you  are driving, 
check  your various 
gages  to  see  if they are 
in the warning zones.

OIL 
The  oil  pressure  gage  shows  the engine  oil pressure in 
psi (pounds  per square  inch) when the  engine is running. 
Canadian vehicles indicate pressure  in kPa.  Oil pressure 
may  vary  with engine  speed, outside  temperature  and  oil 
viscosity, but readings  above the red warning zone 
indicate  the normal operating range. 
A reading in the red zone  may  be caused by a 
dangerously low oil level  or other  problem causing low 
oil  pressure. Have your  vehicle serviced immediately.

When to Add Oil 
If  the  oil  is  at or below  the ADD line, then you’ll  need to 
add  some  oil.  But  you  must  use  the  right  kind.  This  put 
explains  what  kind 
of oil  to  use.  For  crankcase  capacity, 
see  “Capacities  and  Specifications” 
in the  Index. 
I NOTICE: 
Don’t  add  too  much  oil. If your  engine has so 
much  oil  that  the oil level  gets  above  the  upper 
mark  that  shows  the  proper  operating  range, 
your  engine  could  be damaged. 
Just fill it enough  to put the level  somewhere in the 
proper  operating  range. Push the dipstick  all  the  way 
back  in  when  you’re  through. 
What Kind of Oil to Use 
Oils of the proper quality for your  vehicle can be 
identified 
by looking  for  the “Starburst”  symbol.  The 
“Starburst”  symbol  indicates that the 
oil has been 
certified  by the American  Petroleum  Institute 
(API), and 
is  preferred  for use 
in your  gasoline  engine. 
If you change your  own oil, be sure  you use oil that has 
the  “Starburst”  symbol 
on the front of the oil container. 
If you  have your oil changed for you, be sure the  oil  put 
into your  engine is American  Petroleum Institute 
certificd 
for gasoline  engines. 
You  should also  use  the proper  viscosity  oil 
for your 
vehicle, 
as shown in the  following  chart:

DO  NOT USE SAE 2OW-50 OR ANY  OTHER

- 
As shown in the  chart, SAE 5W-30 is best  for your 
vehicle. However,  you can use 
SAE 1OW-30 if  it’s  going 
to be 0°F (- 1 8 “C) or  above.  These  numbers on an oil 
container 
show its viscosity, or thickness. Do not use 
other viscosity  oils, such  as 
SAE 20W-SO. 
NOTICE: 
Use only  engine  oil  with  the  American  Petroleum 
Institute  Certified  For  Gasoline  Engines 
“Starburst”  symbol.  Failure 
to use  the  proper  oil 
can  result  in  engine  damage  not  covered  by  your

Don’t add  anything  to your oil.  Your Oldsmobile retailer 
is  ready 
to advise  if  you think something should be 
added.
