When To Add Engine Oil; What Kind Of Engine Oil To Use - Buick 2004 Park Avenue 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 will 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 5-108.
Notice: Do not 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 are
through.
