What To Do With Used Oil - Chevrolet 2011 HHR Owner's Manual

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 earlier in this
section 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.
