check oil CHEVROLET SILVERADO 2009 2.G Owner's Manual

Owner Checks and Services on page 6-11tells what
should be checked, when to check it, and what can easily
be done to help keep the vehicle in good condition.
The proper replacement parts, uids, and lubricants to
use are listed inRecommended Fluids and Lubricants on
page 6-15andMaintenance Replacement Parts on
page 6-17. When the 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 parts
from your dealer/retailer.
Scheduled Maintenance (Gasoline
Engine)
This maintenance section applies to vehicles with a
gasoline engine. For diesel engine vehicles, see
the maintenance schedule section in the DURAMAX
®
Diesel manual.
When the CHANGE ENGINE OIL SOON message
displays, service is required for the vehicle. Have the
vehicle serviced as soon as possible within the next
600 miles (1 000 km). It is possible that, if driving under
the best conditions, the engine oil life system may not
indicate that vehicle service is necessary for over a year.
However, the engine oil and lter must be changed at
least once a year and at this time the system must bereset. 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,
service the vehicle within 3,000 miles (5 000 km)
since the last service. Remember to reset the oil life
system whenever the oil is changed. SeeEngine Oil Life
System on page 5-18for 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 “MaintenanceI” and “MaintenanceII.”
Generally, it is recommended that the rst service be
MaintenanceI, the second service be MaintenanceII,
and then alternate MaintenanceIand MaintenanceII
thereafter. However, in some cases, MaintenanceIImay
be required more often.
MaintenanceI— Use MaintenanceIif the CHANGE
ENGINE OIL SOON message displays within 10 months
since the vehicle was purchased or MaintenanceII
was performed.
MaintenanceII— Use MaintenanceIIif the previous
service performed was MaintenanceI. Always use
MaintenanceIIwhenever the message displays
10 months or more since the last service or if the
message has not come on at all for one year.
