2007 CADILLAC CTS oil viscosity

Check Engine Oil Pressure Message
Your vehicle may have
this feature. When you
see this ashing
symbol, the engine oil
pressure is low.
To acknowledge this warning, press either button
on the outboard switch on the left spoke of the
steering wheel. After you press this button,
the warning will redisplay every 10 minutes until
the pressure returns to the normal operating
range. Oil pressure should be 20 to 80 psi
(140 to 550 kPa). In certain situations such as
long, extended idles on hot days, it could read as
low as 6 psi (40 kPa) and still be considered
normal. It may vary with engine speed, outside
temperature and oil viscosity. The Oil Pressure
Light should also come on. SeeOil Pressure Light
on page 212for more information.
Oil Temperature Warning Message
When you see this
ashing symbol, the
engine oil temperature
is high.
To acknowledge this warning, press either button
on the outboard switch on the left spoke of the
steering wheel. After you press a button, the
warning will come on every 10 minutes until the
temperature returns to the normal operating range.
Driving aggressively or driving on long hills can
cause the engine oil temperature to be higher than
normal. If this warning is displayed during
normal vehicle operation on at roads, your vehicle
may need service. See your dealer for an
inspection. SeeEngine Oil on page 346for more
information.

What Kind of Engine Oil to Use
Look for three things:
GM4718M
Your vehicle’s engine requires a special oil
meeting GM Standard GM4718M. Oils meeting
this standard may be identied as synthetic.
However, not all synthetic oils will meet
this GM standard. Look for and use only an oil
that meets GM Standard GM4718M.Notice:If you use oils that do not have the
GM4718M Standard designation, you can cause
engine damage not covered by your warranty.
SAE 5W-30
As shown in the viscosity chart, SAE 5W-30 is
best for your vehicle.
These numbers on an oil container show its
viscosity, or thickness. Do not use other
viscosity oils such as SAE 20W-50.
Oils meeting these
requirements should
have the starburst
symbol on the
container. This
symbol indicates that
the oil has been
certied by the
American Petroleum
Institute (API).
Look for this on the oil container, and use only
those oils that are identied as meeting GM
Standard GM4718M and have the starburst symbol
on the front of the oil container.

Lubricants

your dealer.
Usage Fluid/Lubricant
Engine OilThe engine requires a special
engine oil meeting GM Standard
GM4718M. Oils meeting this
standard can be identied as
synthetic, and should also be
identied with the American
Petroleum Institute (API) Certied
for Gasoline Engines starburst
symbol. However, not all synthetic
API oils with the starburst symbol
will meet this GM standard.
Look for and use only an oil that
meets GM Standard GM4718M.
