Engine Oil (5.5L LT6 Engine)
To ensure proper engine performance and
long life, pay careful attention to engine oil.
Follow these important steps:
.Use engine oil approved to the proper
specification and of the proper viscosity
grade. See“Selecting the Right Engine
Oil” later in this section.
.Check the engine oil level regularly and
maintain the proper oil level. See
“Checking Engine Oil” and“When to Add
Engine Oil” later in this section.
.Change the engine oil at the appropriate
time. SeeEngine Oil Life System 0252.
.Always dispose of engine oil properly. See
“What to Do with Used Oil” in this
section.
Checking the Engine Oil
1. Engine Oil Dipstick
2. Engine Oil Fill Cap
Check the engine oil level regularly, every
650 km (400 mi), especially prior to a long
trip. To get an accurate reading, the vehicle
must be parked on a level ground.
The engine oil dipstick handle is a loop. See
Engine Compartment Overview 0238 for the
location.
The vehicle has a racetrack-ready dry sump
engine lubrication system. This high
performance system operates differently
than a standard engine lubrication system
and requires a special procedure when
checking the engine oil level. Follow this
procedure closely.
The engine oil level must be checked when
the engine is warm. Cold oil level in the dry
sump tank may not indicate the actual
amount of oil in the system. Engine oil is
contained in an external tank, separate from
the engine. Under normal operating
conditions, the oil pan under the engine
does not store any oil. If the vehicle has
been parked for an extended period without
the engine being started, some oil will seep
back into the oil pan. This will reduce the
amount of oil held in the dry sump tank and there could be no engine oil on the
dipstick. This is normal since the dipstick is
designed to read the engine oil level only
after the engine has run long enough to
reach normal operating temperature. Do not
add engine oil based on cold engine dipstick
readings. The engine oil level on the dipstick
must be checked while the engine is running
at idle.
To check the engine oil:
1. Turn the engine on and let it warm up to at least 80 °C (175 °F).
2. Once the engine is warm, check the oil while the engine is running at idle.
{Warning
The engine oil dipstick handle may be
hot; it could burn you. Use a towel or
glove to touch the dipstick handle.
3. Remove the dipstick and wipe it with a clean lint-free paper towel or a cloth.
Re-insert the dipstick and push it all the
way in until it stops.

17272984) - 2024 - CRC - 2/20/23
Vehicle Care 247
4. Remove the dipstick again and read thelevel on the cross-hatched area. Re-insert
the dipstick and push it all the way in
until it stops.
5. Turn the engine off.
When to Add Engine Oil
If the oil is below the cross-hatched area at
the tip of the dipstick, add 1 L (1 qt) of the
recommended oil through the oil fill cap
opening in the oil tank fill tube and then
recheck the level. See “Selecting the Right
Engine Oil” later in this section for the type
of oil to use. For engine oil crankcase
capacity, see Capacities and Specifications
0 325.
Caution
Do not add too much oil. Oil levels above
or below the acceptable operating range
shown on the dipstick are harmful to the
engine. If the oil level is above the
operating range (i.e., 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. Drain the excess oil or limit
driving of the vehicle, and seek a service
professional to remove the excess oil.
See Engine Compartment Overview 0238 for
the location of the external engine oil tank
dipstick and fill cap.
Add enough oil to put the level somewhere
in the proper operating range. Push the
dipstick all the way back into the oil tank
tube when finished.
Changing the Engine Oil and Filter
The vehicle requires a special procedure
when changing the engine oil and filter.
Follow this procedure closely.
1. Engine Oil Drain Plug
2. Drain Plug O-ring Seal
3. Engine Oil Drain Plug
4. Drain Plug O-ring Seal
5. Engine Oil Filter Cap
6. Engine Oil Filter Cap O-ring Seal
7. Engine Oil Filter Element
To change the engine oil and filter:
1. Run the engine at idle for about 20 seconds to return all of the oil back
into the dry sump oil tank.
2. Turn the engine off prior to draining the oil and remove the oil fill cap so the oil
tank can breathe while it’s draining.

17272984) - 2024 - CRC - 2/20/23
248 Vehicle Care
3. Remove the engine oil drain plug (1)from the bottom of the engine oil tank.
Drain plug removal will let the oil drain
from the external oil tank. Allow the oil
to drain.
4. Inspect the drain plug O-ring seal (2) and replace if it is damaged. Reinstall the
drain plug into the oil tank by rotating it
to a stop.
5. Remove the engine oil drain plug (3) from the bottom of the engine
crankcase. Drain plug removal will let the
residual oil drain from crankcase sump.
Allow the oil to drain.
6. Inspect the drain plug O-ring seal (4) and replace if it is damaged. Reinstall the
drain plug into the crankcase sump and
tighten them to 25 Y(18 lb ft).
7. Remove the engine oil filter cap (5) and filter (7) and allow the oil to drain.
8. Install the engine oil filter cap (5) with a new engine oil filter cap seal ring (6) and
the new oil filter element (7) and hand
tighten. See Maintenance Replacement
Parts 0321 for the correct filter.
Tighten the engine oil filter cap (5) to
25 Y (18 lb ft). 9. Add oil to the oil tank through the
opening in the oil tank. See Capacities
and Specifications 0325.
10. Install the oil fill cap and insert the dipstick until fully seated to a stop,
if removed.
{Warning
To help avoid personal injury and/or
engine damage, always install the engine
oil dipstick and oil fill cap until fully
seated to a stop. If not fully seated, oil
could escape on to hot exhaust parts and
cause a fire.
11. Start the engine and check the oil level as described under "Checking the Engine
Oil." previously in this section.
Selecting the Right Engine Oil
Selecting the right engine oil depends on
both the proper oil specification and the
viscosity grade. See Recommended Fluids
and Lubricants 0320.
Specification
Use engine oils that meet the dexosR
Performance Engine Oil specification.
Engine oils that have been approved by GM
as meeting the dexosR specification are
marked with the dexosR approved logo. See
www.gmdexos.com.
GM recommends Mobil 1 engine oils that
show the dexosR approved logo.
Caution
Failure to use the recommended engine
oil or equivalent can result in engine
damage not covered by the vehicle
warranty.
Viscosity Grade
Use SAE 5W-50 viscosity grade engine oil.
When selecting an oil of the appropriate
viscosity grade, it is recommended to select
an oil of the correct specification. See
“Specification” previously in this section.

17272984) - 2024 - CRC - 2/20/23
Vehicle Care 249
Engine Oil Additives/Engine Oil Flushes
Do not add anything to the oil. The
recommended oils meeting the dexos
specification are all that is needed for good
performance and engine protection.
Engine oil system flushes are not
recommended and could cause engine
damage not covered by the vehicle
warranty.
What to Do with Used Oil
Used engine oil contains certain elements
that can be unhealthy for your skin and
could even cause cancer. Do not let used oil
stay on your skin for very long. Clean your
skin and nails with soap and water, or a
good hand cleaner. Wash or properly
dispose of clothing or rags containing used
engine oil. See the manufacturer's warnings
about the use and disposal of oil products.
Used oil can be a threat to the environment.
If you change your own oil, drain all the oil
from the filter before disposal. Never dispose
of oil by putting it in the trash or pouring it
on the ground, into sewers, or into streams
or bodies of water. Recycle it by taking it to
a place that collects used oil.
