Scheduled Maintenance (Gasoline Engine) - Chevrolet Silverado 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 SOON 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 dealer/retailer has
trained service technicians who will perform this
work using genuine 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
on page 511 for information on the Engine Oil Life
System and resetting the system.
When the CHANGE ENGINE OIL SOON 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.
