How Often Should A Heavy-Duty Truck Get An Oil Change?
Oil change intervals vary based on engine type, load conditions, and operating hours. Many heavy-duty trucks require oil changes every 10,000 to 25,000 miles, but severe-duty use may require more frequent service to prevent engine wear.
What Happens If Fluids Aren’t Changed Regularly?
Neglected fluids can become contaminated, lose lubrication properties, and overheat components. This increases friction and wear, potentially leading to engine damage, transmission failure, overheating, and costly repairs that routine maintenance could have prevented.
