Selecting The Right Schedule; Short Trip/City Intervals; Short Trip/City Definition - GMC Jimmy 2004 Owner's Manual

Selecting the Right Schedule

First you will need to decide which of the two schedules
is right for your vehicle. Here is how to decide which
schedule to follow:
Short Trip/City Definition
Follow the Short Trip/City Scheduled Maintenance if any
one of these conditions is true for your vehicle:
•
Most trips are less than 5 miles (8 km). This is
particularly important when outside temperatures
are below freezing.
•
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
•
You frequently tow a trailer or use a carrier on top
of your vehicle.
•
If the vehicle is used for delivery service, police,
taxi or other commercial application.
One of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break
down sooner.
