When To Add Engine Oil - Hummer 2008 H3 Owner's Manual

When to Add Engine Oil

If the oil is below the cross-hatched area (L), 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 5-107.
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.
5-16
Be sure to 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 5-12 for
the location of the
engine oil fill cap.
