Cadillac SRX Owner Manual - 2011
Vehicle Care 10-13
dexos™ specification or equivalent
should not be used for an oil
change. In the event that dexos™
approved engine oil is not available
for maintaining proper oil level,
however, you may use substitute
engine oil displaying the API
Starburst symbol and of SAE 5W-30
viscosity grade. Extensive use of
oils that do not meet the dexos™
specification, however, may
result in reduced performance or
engine damage under certain
circumstances.
Maintaining the proper oil level is
very important. However, if you
use a substitute oil for any reason,
we recommend that you perform
a complete oil change back to
dexos™ as soon as possible to
protect the engine and maintain
the engine's peak performance.
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.
