After how many hours of operation should the oil be changed for new engines?

Changing the oil in a new engine after five hours of operation is a standard maintenance practice recommended by many manufacturers. This early oil change is crucial because new engines can have metal shavings and debris from the manufacturing process that might circulate in the oil. These contaminants can lead to wear and tear on the engine components if not removed quickly.

In addition to removing debris, changing the oil early ensures that the engine is lubricated with clean oil, allowing it to perform optimally. The new oil contains additives that are important for engine performance and protection, and replacing the initial oil after five hours helps to establish a solid foundation for long-term engine health.

Other choices suggest longer intervals which may not adequately account for the immediate breaking-in process of new engines. Operating a new engine with old oil beyond the recommended interval could increase the risk of engine damage and reduce its overall lifespan.
