When To Add Engine Oil - Pontiac 2004 Grand Prix Owner's Manual

When to Add Engine Oil

If the oil is at or below the cross-hatched area at the tip
of the dipstick, then you'll need to add at least one
quart of oil. But you must use the right kind. This section
explains what kind of oil to use. For engine oil
crankcase capacity, see Capacities and Specifications
on page 5-104 .
Notice: Don't add too much oil. If your engine has
so much oil that the oil level gets above the
cross-hatched area that shows the proper operating
range, your engine could be damaged.
Be sure to add enough oil to put the level somewhere in
the proper operating range in the cross-hatched area.
Push the dipstick all the way back in when you're through.
See Engine Compartment
Overview on page 5-12 for
the location of the
engine oil fill cap.
