When To Add Engine Oil - Chevrolet 2008 Cobalt Owner's Manual

When to Add Engine Oil

If the oil is below the MIN (minimum) mark, add at least
one quart/liter of the recommended oil. This section
explains what kind of oil to use. For engine oil crankcase
capacity, see Capacities and Specifications on
page 5-112.
Notice: Do not add too much oil. If the engine
has so much oil that the oil level gets above the
upper mark that shows the proper operating range,
the engine could be damaged.

Be sure to add enough oil to put the level somewhere
in the proper operating range. Push the dipstick all
the way back in when you are through.
See Engine Compartment
Overview on page 5-12
for the location of the
engine oil fill cap.
