Scheduled Maintenance (Gasoline Engine) - GMC Sierra Classic 2007 Owner's Manual

If you want to purchase service information, see
Service Publications Ordering Information on
page 652.
Owner Checks and Services on page 621 tells you
what should be checked, when to check it, and
what you can easily do to help keep your vehicle in
good condition.
The proper replacement parts, fluids, and
lubricants to use are listed in Recommended
Fluids and Lubricants on page 625 and Normal
Maintenance Replacement Parts (Gasoline
Engines) on page 628. When your vehicle is
serviced, make sure these are used. All parts
should be replaced and all necessary repairs done
before you or anyone else drives the vehicle.
We recommend the use of genuine GM parts.
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.
