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 part
explains what kind of oil to use. For engine oil crankcase
capacity, see
Capacities and Specifications on
page 5-106.
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.
The engine oil fill cap for
the VORTEC™ 4800,
5300, 6000 and 8100 V8
engine is located on
the engine valve cover, on
the passenger’s side of
the vehicle.
Your vehicle may have a cap with text and a graphic, or
just a graphic as shown. See
Engine Compartment
Overview on page 5-12 for more information on location.
Be sure to fill it enough to put the level somewhere in
the proper operating range. Push the dipstick all the way
back in when you’re through.
