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

When to Add Engine Oil

If the oil is below 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 6-90.
Notice: Do not add too much oil. If the engine has
so much oil that the oil level gets above the
cross-hatched area that shows the proper operating
range, the engine could be damaged.
6-16
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 6-12 for
the location of the engine
oil fill cap.
