Severe service shortens every interval
Frequent short trips, towing, mountain driving, sustained idling or dusty conditions are "severe service" for every manufacturer: cut the oil interval roughly in half and inspect filters more often. The table above reflects normal service — your owner's manual has the severe-service column and is the authority for your vehicle.
