Engine Oil
If your vehicle is equipped
with the 3 100 engine,
there is a CHECK OIL
CHECK
OIL
light in your instrument
panel cluster.
If the CHECK OIL light on the instrument panel comes
on, it means you need to check your engine oil level
right away. For more information, see "Check Oil
Light" in the Index. You should check your engine oil
level regularly; this is an added reminder.
It's a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil must
be warm and the vehicle must be on level ground.
