When To Add Engine Oil - Buick Enclave 2008 Owner's Manual

When to Add Engine Oil

If the oil is below the cross-hatched area at the tip of the
dipstick, you need to add at least one quart/liter 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 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.
5-14
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.
