---

Short Answer:

Service intervals depend on your truck’s size, engine, and use:

• Light-duty (half-ton): Oil every 7,500–10,000 miles, fuel and air filters every 15,000–30,000 miles.
• Medium-duty (1-ton): Oil every 6,000–10,000 miles, fuel and air filters every 10,000–20,000 miles.
• Heavy-duty (diesel, Class 3–5): Oil every 5,000–10,000 miles, fuel and air filters every 10,000–20,000 miles.

Short Answer:

Most trucks between 50,000 and 75,000 miles need drivetrain services like transmission, differential, and transfer case fluid changes—especially if the truck is used for towing or heavy work. These services are typically recommended at your mileage to help prevent overheating, gear wear, and costly drivetrain failures. Even if there are no warning signs yet, preventive service can significantly extend the life of your truck.
