How often should oil be changed in heavy-duty trucks?

The recommended oil change interval for heavy-duty trucks is typically every 10,000 to 15,000 kilometers. This range is based on several factors, including the type of oil used, engine design, and operating conditions. Heavy-duty trucks often operate under more challenging conditions than lighter vehicles, including higher loads, longer operating times, and more exposure to contaminants. Regular oil changes within this interval help maintain optimal engine performance by ensuring that the oil retains its lubricating properties and effectively removes contaminants.

Using synthetic oils or advanced formulations can sometimes allow for longer intervals, but the general consensus still falls within the 10,000 to 15,000-kilometer range for conventional oils. This practice supports the integrity of the engine, minimizes wear, and prolongs its lifespan. Additionally, adhering to the manufacturer's recommendations is crucial for warranty compliance and overall vehicle reliability.
