10-8 Vehicle Care
Engine Oil
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.Always use engine oil approved
to the proper specification and of
the proper viscosity grade. See
“Selecting the Right Engine Oil.”
.Check the engine oil level
regularly and maintain the
proper oil level. See“Checking
Engine Oil” and“When to Add
Engine Oil.”
.Change the engine oil at the
appropriate time. See Engine Oil
Life System on page 10‑10.
.Always dispose of engine oil
properly. See “What to Do With
Used Oil.”
Checking Engine Oil
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle
must be on level ground. The
engine oil dipstick handle is a yellow
loop. See Engine Compartment
Overview on page 10‑6 for the
location of the engine oil dipstick.
Obtaining an accurate oil level
reading is essential:
1. If the engine has been running recently, turn off the engine and
allow several minutes for the oil
to drain back into the oil pan.
Checking your oil level too soon
after engine shut off will not
provide an accurate oil level
reading.
2. Pull out the dipstick and clean it with a paper towel or cloth, then
push it back in all the way.
Remove it again, keeping the tip
down, and check the level.
When to Add Engine Oil
If the oil is below the cross-hatched
area at the tip of the dipstick, add
one liter/quart of the recommended
oil and then recheck the level. See
“Selecting the Right Engine Oil” for
an explanation of what kind of oil to
use. For engine oil crankcase
capacity, see Capacities and
Specifications on page 12‑2.
Notice: 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 you find that you
have an oil level 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

Black plate (9,1)Chevrolet Impala Owner Manual - 2011
Vehicle Care 10-9
operating range, the engine could
be damaged. You should drain
out the excess oil or limit your
driving of the vehicle and seek a
service professional to remove
the excess amount of oil.
SeeEngine Compartment Overview
on page 10‑6 for the location of the
engine oil fill cap.
Add enough oil to put the level
somewhere in the proper operating
range. Push the dipstick all the way
back in when through.
Selecting the Right Engine Oil
Selecting the right engine oil
depends on both the proper oil
specification and viscosity grade:
Specification
Use and ask for engine oils with the
dexos™ certification mark. Oils
meeting the requirements of your
vehicle should have the dexos™
certification mark on the container. This certification mark indicates that
the oil has been approved to the
dexos™
specification.
Your vehicle was filled at the factory
with dexos™ approved engine oil.
Notice: Use only engine oil that is
approved to the dexos™
specification or an equivalent
engine oil of the appropriate
viscosity grade. Engine oils
approved to the dexos™
specification will show the
dexos™ symbol on the container.
Failure to use the recommended
engine oil or equivalent can result
in engine damage not covered by
the vehicle warranty. If you are
unsure whether your oil is
approved to the dexos™
specification, ask your service
provider. Use of Substitute Engine Oils if
dexos™
is unavailable: In the event
that dexos™ approved engine oil is
not available at an oil change or for
maintaining proper oil level, you
may use substitute engine oil
displaying the API Starburst symbol
and of SAE 5W-30 viscosity grade.
Use of oils that do not meet the
dexos™ specification, however, may
result in reduced performance under
certain circumstances.
Viscosity Grade
SAE 5W-30 is the best viscosity
grade for the vehicle. Do not use
other viscosity oils such as
SAE 10W‐30, 10W‐40, or 20W-50.

Black plate (10,1)Chevrolet Impala Owner Manual - 2011
10-10 Vehicle Care
Cold Temperature Operation: In an
area of extreme cold, where the
temperature falls below−29°C
(−20°F), an SAE 0W-30 oil should be used. An oil of this viscosity
grade will provide easier cold
starting for the engine at extremely
low temperatures. When selecting
an oil of the appropriate viscosity
grade, be sure to always select
an oil that meets the required
specification, dexos™. See
“Specification”
for more information.
Engine Oil Additives/Engine
Oil Flushes
Do not add anything to the oil. The
recommended oils with the dexos™
specification and displaying the
dexos™certification mark 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, be sure to 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.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that indicates when to change the
engine oil and filter. This is based
on engine revolutions and engine
temperature, and not on mileage.
Based on driving conditions, the
mileage at which an oil change is
indicated can vary considerably.

Black plate (11,1)Chevrolet Impala Owner Manual - 2011
Vehicle Care 10-11
For the oil life system to work
properly, the system must be reset
every time the oil is changed.
When the system has calculated
that oil life has been diminished, it
indicates that an oil change is
necessary. A CHANGE ENGINE
OIL SOON message comes on.
SeeDIC Warnings and Messages.
Change the oil as soon as possible
within the next 1 000 km (600 miles).
It is possible that, if driving under
the best conditions, the oil life
system might indicate that an oil
change is not necessary for up to a
year. The engine oil and filter must
be changed at least once a year
and, at this time, the system must
be reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the
proper level. If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 miles)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. Always reset the
engine oil life to 100% after every oil
change. It will not reset itself.
To reset the system:
1. Display OIL LIFE REMAINING
on the DIC.
2. Press and hold the SET/RESET button on the DIC for more than
five seconds. The oil life will
change to 100%.
If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not reset. Repeat the
procedure.
Automatic Transmission
Fluid
When to Check and Change
Automatic Transmission Fluid
A good time to check the automatic
transmission fluid level is when the
engine oil is changed.
Change the fluid and filter at the
intervals listed in Scheduled
Maintenance on page 11‑2, and be
sure to use the transmission fluid
listed in Recommended Fluids and
Lubricants on page 11‑6.
How to Check Automatic
Transmission Fluid
Because this operation can be a
little difficult, it may be decided to
have this done at the dealer service
department.
If not taken to the dealer, be sure
to follow all the instructions here,
or a false reading on the dipstick
could result.

Black plate (12,1)Chevrolet Impala Owner Manual - 2011
10-12 Vehicle Care
Notice:Too much or too
little fluid can damage the
transmission. Too much can
mean that some of the fluid could
come out and fall on hot engine
parts or exhaust system parts,
starting a fire. Too little fluid
could cause the transmission to
overheat. Be sure to get an
accurate reading if checking the
transmission fluid.
Wait at least 30 minutes before
checking the transmission fluid level
if you have been driving:
.When outside temperatures are
above 32°C (90°F).
.At high speed for quite a while.
.In heavy traffic —especially in
hot weather.
.While pulling a trailer.
To get the right reading, the fluid
should be at normal operating
temperature, which is 82°C to
93°C (180°F to 200°F). Get the vehicle warmed up by
driving about 24 km (15 mi) when
outside temperatures are above
10°C (50°F). If it is colder than
10°C (50°F), the vehicle may have
to be driven longer.
Checking the Fluid Level
Prepare your vehicle as follows:
1. Park the vehicle on a level
place. Keep the engine running.
2. With the parking brake applied, place the shift lever in P (Park).
3. With your foot on the brake pedal, move the shift lever
through each gear range,
pausing for about three seconds
in each range. Then, position the
shift lever in P (Park).
4. Let the engine run at idle for three to five minutes. Then, without shutting off the
engine, follow these steps:
1. Pull out the dipstick and wipe it
with a clean rag or paper towel.
The transmission fluid dipstick
handle is the black loop with this
symbol on it. It is located near
the rear of the engine
compartment.
See Engine Compartment
Overview on page 10‑6 for more
information on location.
2. Push it back in all the way, wait three seconds, and then pull it
back out again.

Black plate (13,1)Chevrolet Impala Owner Manual - 2011
Vehicle Care 10-13
3. Check both sides of thedipstick, and read the lower
level. The fluid level must be in
the cross-hatched area.
4. If the fluid level is in the acceptable range, push the
dipstick back in all the way.
How to Add Fluid
Refer to Recommended Fluids and
Lubricants on page 11‑6 to
determine what kind of transmission
fluid to use. If the fluid level is low, add only
enough of the proper fluid to bring
the level into the cross-hatched
area on the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add
enough fluid at the dipstick hole
to bring it to the proper level.
It does not take much fluid,
generally less than 0.5 L (1 pt).
Do not overfill.
Notice: Use of the incorrect
automatic transmission fluid may
damage the vehicle, and the
damages may not be covered by
the vehicle's warranty. Always
use the automatic transmission
fluid listed in Recommended
Fluids and Lubricants on
page 11‑6.
3. After adding fluid, recheck the fluid level as described under
“How to Check Automatic
Transmission Fluid,” earlier in
this section. 4. When the correct fluid level is
obtained, push the dipstick back
in all the way.
Engine Air Cleaner/Filter
The engine air cleaner/filter is
located in the engine compartment
on the driver side of the vehicle.
See Engine Compartment Overview
on page 10‑6 for more information
on location.
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/filter at the
scheduled maintenance intervals
and replace it at the first oil change
after each (80 000 km (50,000 mi)
interval. See Scheduled
Maintenance on page 11‑2 for more
information. If driving in dusty/dirty
conditions, inspect the filter at each
engine oil change.

How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/filter,
remove the filter from the vehicle
and lightly shake the filter to release
loose dust and dirt. If the filter
remains caked with dirt, a new filter
is required.
To inspect or replace the engine air
cleaner/filter do the following:
1. Lift the filter cover tabs on top ofthe engine air cleaner/filter
housing.
2. Push the filter cover housing
toward the engine.
3. Pull out the filter.
4. Inspect or replace the engine air cleaner/filter.
5. To reinstall the cover, position the tabs through the hinges on
the housing.
6. Push the cover tabs on top of the housing to lock the cover
in place.
{WARNING
Operating the engine with the
air cleaner/filter off can cause you
or others to be burned. The air
cleaner not only cleans the air; it
helps to stop flames if the engine
backfires. Use caution when
working on the engine and do not
drive with the air cleaner/filter off.
Notice: If the air cleaner/filter is
off, dirt can easily get into the
engine, which could damage it.
Always have the air cleaner/filter
in place when you are driving.
