Service & Appearance Care
This doughnut-shaped logo (symbol) is
used on most oil containers to help you
select the correct oil.
You should look for this
on the oil
container, and use
only those oils that
display the logo.
GM Goodwrench@ oil (in Canada, GM
‘
Engine Oil) meets all the requirements
for your vehicle.
Engine Oil Additives: Don’t add
anything to
your oil. Your Geo 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
(6 km).
It’s below freezing outside and most
trips are less than
10 miles (16 km).
The engine is at low speed most of
the time (as in door-to-door delivery,
or
in stop-and-go traffic).
You tow a trailer often.
Most trips are through dusty places.
The vehicle is frequently operated
off-road.
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.
If none of them is true, change oil and
filter every
7,500 miles (12 500 km) or
7.5 months - whichever comes first.

What to Do with Used Oil:
CAUTION
Used engine oil contains
D things that have caused skin
Gancer in laboratory animals.
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. 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 it by 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 your Maintenance Schedule to
determine when to replace the air filter.
See “Scheduled Maintenance Services”
in the Index.
A Operating the engine with the
L air cleaner off can cause you
or others to be burned. The air
cleaner not only cleans the air, it
stops flame if the engine backfires.
If it 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.
