Severe Service Defined
SEVERE SCHEDULE DEFINITION
Follow the SEVERE schedule if any one of the following are true:
- Most trips are less than 5 to 10 miles (8 to 16 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).
- Trailer towing or using a carrier on top of the vehicle frequently.
- The vehicle is used for delivery service, police, taxi or other commercial applications.
NOTES:
Some vehicle manufacturers provide only a single schedule (Normal) for all driving conditions. Some of the components listed in the schedule may have notes describing alternate service intervals for that component depending on driving conditions.
Many vehicles have an "Engine Oil Life Monitor" lamp which can illuminate anytime between intervals depending on driving conditions. The oil should then be replaced at that time, regardless of mileage, and the "Engine Oil Life Monitor" reset.
