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 6‑18.
.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 6‑14for the location of the engine oil dipstick.
6-15

Black plate (16,1)Cadillac DTS Owner Manual - 2011
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 6‑112. 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
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.
See Engine Compartment Overview
on page 6‑14for
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.
6-16

Black plate (17,1)Cadillac DTS Owner Manual - 2011
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.
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.
6-17

Black plate (18,1)Cadillac DTS Owner Manual - 2011
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.
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 in the Driver
Information Center (DIC) comes on. Change the oil as
soon as possible within the next 600 miles (1 000 km).
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 3,000 miles (5 000 km) 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. To reset the system:1. Turn the ignition to ON/RUN, with the engine off.
2. Press the DIC INFO button until OIL LIFE REMAINING displays. See DIC Operation and
Displays on page 4‑60.
3. Press and hold the DIC INFO RESET button until 100% displays.
4. Turn the key to LOCK/OFF.
If the CHANGE ENGINE OIL SOON message comes
back on when the vehicle is started, the engine oil life
system has not been reset. Repeat the procedure.
Engine Air Cleaner/Filter
See Engine Compartment Overviewon page 6‑14for
the location of the engine air cleaner/filter.
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 50,000 mile (80 000 km) interval.
See Scheduled Maintenance
on page 7‑3for more
information. If you are 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.
6-19

Black plate (20,1)Cadillac DTS Owner Manual - 2011
To inspect or replace the filter:
1. Remove the two screws on the top of the engineair cleaner/filter cover.
2. Lift up the outboard side of the cover at an angle while pulling toward you. This is necessary due to
the two hinges located on the inboard side of the
cover.
3. Remove the engine air cleaner/filter and any loose debris that may be found in the air cleaner base.
4. Inspect or replace the air filter element. To reinstall the cover:
1. Align the two hinges located on the inboard side of the cover.
2. Push the cover slightly down and towards the engine to engage the tabs in the hinges and align
the two screws.
3. Tighten the two screws on the top of the engine air cleaner/filter cover.
{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.
