Operation CHARM: Car repair manuals for everyone.

Severe Service Defined



Selecting the Right Schedule

Short Trip/City Definition

Follow the Short Trip/City Scheduled Maintenance if any one of these conditions is true for your vehicle:
1. Most trips are less than 5 miles (8 km). This is particularly important when outside temperatures are below freezing.
2. Most trips include extensive idling, such as frequent driving in stop-and-go traffic.
3. 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.
