2006 PONTIAC GTO oil capacities

When to Add Engine Oil
If the oil is below the cross-hatched area at the tip of
the dipstick, you will 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 Speci®cations on
page 5-90.
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.See
Engine Compartment
Overview on page 5-12for
the location of the
engine oil ®ll cap.
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.

{CAUTION:
Never use oil or grease on studs or nuts. If
you do, the nuts might come loose. Your wheel
could fall off, causing a serious accident.

the nuts toward the wheel. Tighten each nut by
hand until the wheel is held against the hub.
12. Lower the vehicle by turning the wheel wrench
counterclockwise. Lower the jack completely.
{CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to come loose
and even come off. This could lead to an
accident. Be sure to use the correct wheel
nuts. If you have to replace them, be sure to
get new GM original equipment wheel nuts.
CAUTION: (Continued)
CAUTION: (Continued)
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench to the
proper torque speci®cation. See
Capacities
and Speci®cations on page 5-90
for wheel nut
torque speci®cation.
Notice:Improperly tightened wheel nuts can lead to
brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper torque
speci®cation. See
Capacities and Speci®cations on
page 5-90for the wheel nut torque speci®cation.
