When To Add Engine Oil - Cadillac CTS 2008 Owner's Manual

When to Add Engine Oil

If the oil level is within the add 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 5-129.
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 you are through.
See Engine Compartment
