Scheduled Maintenance (Gasoline Engine) - Chevrolet Silverado Classic 2007 Owner's Manual

Scheduled Maintenance
(Gasoline Engine)
This maintenance section applies to vehicles with
a gasoline engine. If your vehicle has a diesel
engine, see the maintenance schedule section in
®
the DURAMAX Diesel Engine Supplement.
When the CHANGE ENGINE OIL message comes
on, it means that service is required for your
vehicle. Have your vehicle serviced 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 engine oil life system may
not indicate that vehicle service is necessary for
over a year. However, your engine oil and
filter must be changed at least once a year and at
this time the system must be reset. Your GM
®
Goodwrench dealer has GM-trained service
technicians who will perform this work using
genuine GM parts and reset the system.
If the engine oil life system is ever reset
accidentally, you must service your vehicle within
3,000 miles (5 000 km) since your last service.
Remember to reset the oil life system whenever the
oil is changed. See Engine Oil Life System
(Gasoline Engine) on page 489 for information on
the Engine Oil Life System and resetting the
system.
When the CHANGE ENGINE OIL message
appears, certain services, checks, and inspections
are required. Required services are described
in the following for "Maintenance I" and
"Maintenance II." Generally, it is recommended
that your first service be Maintenance I, your
second service be Maintenance II, and that you
alternate Maintenance I and Maintenance II
thereafter. However, in some cases,
Maintenance II may be required more often.
