When to Change Engine Oil

If any one of these is true for you, use the short trip/city
maintenance schedule:

This is particularly important when outside
temperatures are below freezing.
D
Most trips include extensive idling (such as frequent
- -

D
Most trips are through dusty areas.

The vehicle is used for delivery service, police, taxi
or other commercial application.
