Engine Oil Life System; (Gasoline Engine) - Chevrolet 2007 Silverado 1500 Pickup Owner's Manual

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 your warranty.
®
GM Goodwrench oil meets all the requirements
for your vehicle.
If you are in an area of extreme cold, where the
temperature falls below 20°F ( 29°C), it is
recommended that you use either an SAE 5W-30
synthetic oil or an SAE 0W-30 oil. Both will
provide easier cold starting and better protection
for the engine at extremely low temperatures.
Engine Oil Additives
Do not add anything to the oil. The recommended
oils with the starburst symbol that meet GM
Standard GM6094M are all you will need for good
performance and engine protection.

Engine Oil Life System

(Gasoline Engine)

When to Change Engine Oil
Your vehicle has a computer system that lets you
know 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 will
be indicated can vary considerably. For the oil life
system to work properly, you must reset the system
every time the oil is changed.
When the system has calculated that oil life has
been diminished, it will indicate that an oil change is
necessary. A CHANGE ENGINE OIL message will
come on. See DIC Warnings and Messages on
page 267. Change the oil as soon as possible
within the next 600 miles (1 000 km). It is possible
that, if you are driving under the best conditions, the
oil life system may not indicate that an oil change is
necessary for over a year. However, 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 GM-trained service people who will perform this
work using genuine GM parts and reset the system.
