GMC 2007 Savana - Manual (Page 399)

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 light 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 300 for information on
the Engine Oil Life System and resetting the
system.
When the change engine oil light 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.
