When To Add Engine Oil - Cadillac 2009 CTS Owner's Manual

When to Add Engine Oil

If the oil level is within the cross-hatched area at the
tip of the dipstick, 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 5-133.
Notice: Do not add too much oil. If the engine has
so much oil that the oil level gets above the proper
operating range and into the upper cross-hatched
area on the dipstick, the engine could be damaged.
Add enough oil to put the level somewhere in the proper
operating range. Push the dipstick all the way back in
when through.
See Engine Compartment
Overview on page 5-14 for
the location of the engine
oil fill cap.
