Additives
To provide cleaner air, all gasolines in the United States
are now required to contain additives that help prevent
engine and fuel system deposits from forming, allowing
the emission control system to work properly. In most
cases, nothing should have to be added to the fuel.
However, some gasolines contain only the minimum
amount of additive required to meet U.S. Environmental
Protection Agency regulations. To help keep fuel
injectors and intake valves clean, or if the vehicle
experiences problems due to dirty injectors or valves,
look for gasoline that is advertised as TOP TIER
Detergent Gasoline.
For customers who do not use TOP TIER Detergent
Gasoline regularly, one bottle of GM Fuel System
Treatment PLUS, added to the fuel tank at every engine
oil change, can help clean deposits from fuel injectors
and intake valves. GM Fuel System Treatment PLUS is
the only gasoline additive recommended by General
Motors. It is available at your dealer.Gasolines containing oxygenates, such as ethers and
ethanol, and reformulated gasolines might be available
in your area. We recommend that you use these
gasolines, if they comply with the specifications
described earlier. However, E85 (85% ethanol) and
other fuels containing more than 10% ethanol must not
be used in vehicles that were not designed for those
fuels.
Notice:
This vehicle was not designed for fuel that
contains methanol. Do not use fuel containing
methanol. It can corrode metal parts in the fuel
system and also damage plastic and rubber parts.
That damage would not be covered under the
vehicle warranty.
Some gasolines that are not reformulated for low
emissions can contain an octane-enhancing additive
called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask the attendant where you buy gasoline
whether the fuel contains MMT. We recommend against
the use of such gasolines. Fuels containing MMT can
reduce the life of spark plugs and the performance of
the emission control system could be affected. The
malfunction indicator lamp might turn on. If this occurs,
return to your dealer for service.

Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel might be hard
to find. Never use leaded gasoline or any other fuel not
recommended in the previous text on fuel. Costly
repairs caused by use of improper fuel would not be
covered by the vehicle warranty.
To check the fuel availability, ask an auto club,
or contact a major oil company that does business in
the country where you will be driving.
Filling the Tank
{WARNING:
Fuel vapor burns violently and a fuel fire can

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 6‑19.
.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.
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 MIN (minimum) mark, 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 6‑107.
Notice: Do not add too much oil. If the engine has
so much oil that the oil level gets above the upper
mark that shows the proper operating range, the
engine could be damaged.
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.
6-16

Black plate (17,1)Chevrolet HHR Owner Manual - 2011
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.
6-17

Black plate (18,1)Chevrolet HHR Owner Manual - 2011
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. 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.
6-18

Black plate (19,1)Chevrolet HHR Owner Manual - 2011
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 the Engine Oil Life System, 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 OIL SOON message comes on. SeeDIC
Warnings and Messages
on page 4‑40. 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 information and reset buttons on the Driver Information Center (DIC) at the same time to
enter the personalization menu. See DIC Vehicle
Personalization on page 4‑45.
3. Press the information button to scroll through the available personalization menu modes until the
DIC display shows OIL‐LIFE RESET.
4. Press and hold the reset button until the DIC display shows ACKNOWLEDGED. This will tell you
the system has been reset.
5. Turn the key to LOCK/OFF.
