When to Add Engine Oil
If the oil is at or below the ADD mark for a
2.2L L4 (LN2) or 2.4L L4 (LD9) engine, or at or below
the MIN mark for a 2.2L L4 ECOTEC (L61) engine,
then you’ll need to add at least one quart of oil. But you
must use the right kind. This part explains what kind of
oil to use. For engine oil crankcase capacity, see
“Capacities and Specifications” in the Index.
NOTICE:
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the upper
mark that shows the proper operating range,
your engine could be damaged.
2.2L L4 (LN2) Engine
This is where you add oil if you have a 2.2L L4 (LN2)
engine. See “Engine Compartment Overview” in the
Index for more information on location.
