2011 CHEVROLET SILVERADO oil viscosity

Black plate (19,1)Chevrolet Silverado Owner Manual - 2011
Instruments and Controls 5-19
Oil pressure can vary with engine
speed, outside temperature and
oil viscosity, but if readings are
outside the normal operating range,
the oil pressure light comes on.
SeeEngine Oil Pressure Light
on
page 5‑32for more information.
A reading outside the normal
operating range can be caused
by a dangerously low oil level or
some other problem causing low
oil pressure. Check the vehicle's
oil as soon as possible. See “OIL
PRESSURE LOW STOP ENGINE”
under Engine Oil Messages
on
page 5‑47and Engine Oilon
page 10‑7.
{WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Notice: Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule for changing engine oil.
If the vehicle has a diesel engine,
see the Duramax diesel supplement
for more information.
If the vehicle is a hybrid, see
the hybrid supplement for more
information.

10-8 Vehicle Care
When to Add Engine Oil
If the oil is below the cross-hatched
area at the tip of the dipstick,
add at least one quart/liter of the
recommended oil. This section
explains what kind of oil to use.
For engine oil crankcase capacity,
seeCapacities and Specifications
on page 12‑2.
Notice: Do not add too much oil.
If 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. See
Engine Compartment Overview
on page 10‑6for 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.
What Kind of Engine Oil to Use
Look for three things:
.GM6094M
Use only an oil that meets GM
Standard GM6094M.
.SAE 5W-30
SAE 5W-30 is best for the
vehicle. These numbers on
an oil container show its
viscosity, or thickness.
Do not use other viscosity
oils such as SAE 20W-50.
.American Petroleum Institute
(API) starburst symbol
Oils meeting these requirements
should have the starburst
symbol on the container. This
symbol indicates that the oil has
been certified by the American
Petroleum Institute (API).
Notice: Use only engine oil
identified as meeting GM
Standard GM6094M and showing
the American Petroleum Institute
Certified For Gasoline Engines
starburst symbol. Failure to use
the recommended oil can result
in engine damage not covered by
the vehicle warranty.
