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 (1 6 km).
The engine is at low speed most of the
time (as
in door-to-door delivery, or
stop-and-go traffic).
You tow a trailer often.
Most trips are through dusty places.
The vehicle is frequently operated
If any one of these is true for your
vehicle, then you need to change your
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 (1 2 500 km) or
7.5 months - whichever comes first.
off-road.
Engine
Coolant Heater (Engine Block
Heater)
An engine coolant heater can be a big
help
if you have to park outside in very
cold weather,
0°F (-I 8°C) or colder. If
your vehicle has this option, see “Engine
Coolant Heater”
in the Index.
What to Do with Used Oil
Did you know that used engine oil
contains 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 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-tlowing 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.

detertnine when to replace the
air filter.

off, and
be careful working
on the engine
with the
air cleaner off.
