Severe-duty schedule
The severe-duty schedule is for trucks that operate under strenuous conditions, such as towing heavy loads, frequent short trips, or in dusty or cold climates. Under these conditions, the oil and filter change interval should be shortened to every 5,000 miles. All other service intervals remain the same, but it is recommended to inspect all fluids and filters more frequently.
Known issues by mileage
- 5,000-15,000 miles: Premature brake wear, especially on trucks used for heavy hauling.
- 30,000 miles: Clogged fuel filters, leading to reduced engine performance.
- 60,000 miles: Transmission shifting issues, often resolved with a fluid service.
- 100,000 miles: Coolant leaks from hoses and radiator.
- 150,000 miles: Timing chain noise, indicating wear and the need for inspection.
Estimated cost per service
- Oil & filter change: $100-$150
