Engine  Oil Additives 
Don’t  add anytkng to your  oil.  Your  Oldsmobile  retailer  is 
ready  ‘to  advise  if  you 
think something  should  be  added. 
When to Change  Engine  Oil

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. 
You  frequently  tow a trailer  or use  a carrier  on top  of 
your  vehicle. 
,’ 
The vehicle  is used  for delivery service, police,  taxi 
or  other commercial application. 
Driving  under these conditions causes engine  oil to 
break  down  sooner.  If any  one of these  is true  for your 
vehicle,  then  you  need  to  change your oil and  filter 
every 3,000 miles (5 000 km) or 3 months -- whichever 
occurs first.  If 
none  of them  is true, 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. 
What to Do with  Used  Oil 
Did  you  know  that used  engine  oil contains certain 
e€ements  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 properly  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  retailer, a service station or a local  recycling 
center  for help.

Operating the.engine wi4.h the air cleaner  oi’fcan 
cause  you or .others to  be burned.  The 
air cleaner 
not  only  cleans  the 
air, it stops flame if the  engine 
backfires.  Hit isn’t  there,  and the engine 
backfires,  you  could 
be burned. Don’t drive with 
it off, and be careful  working  on  the engine  with 
the 
air cleaner off. 
NOTICE: 
If  the  air cleaner is off, a backfii  can cause  a 
damaging  engine  fire.  And,  dirt can easily  get 
into 
your engine, which will damage it. Always 
have  the 
air cleaner in  place  when  you’re  driving.

Automatk Transaxle’ Fluid 
When to Check and Change 
A good time to check  your automaticdransaxle  fiui,d 
level  is when  the engine 
oil is changed. 
Change  both the fluid  and. filter ,every 
30,000 miles 
(83 000 km) if the,  vehicle is mainly  ‘driven under one or 
more  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. 
When  doing frequent trailer  towing. 
Uses such as  found  in :taxi, polide or delivery  service. ,., 
If you  do not  use  your  vehicle under  any  of  these 
conditions,  the fluid  and filter 
.. do not  require  changing. 
See  “Scheduled  Maintenance Services”  in  the Index.
