What is the recommended typical maintenance interval for oil changes in DTNA engines?

The recommended typical maintenance interval for oil changes in DTNA engines is every 15,000 miles. This interval is based on extensive testing and engineering evaluations that take into account the performance and longevity of the engine. Changing the oil at this interval helps ensure that the engine operates efficiently and remains protected from wear caused by contaminants and degradation of the oil itself.

When oil changes are performed regularly as recommended, it helps in maintaining optimal lubrication, which is crucial for engine health. Additionally, adhering to this schedule can enhance fuel efficiency, reduce emissions, and prolong the overall lifespan of the engine components. While some engines may suggest more or less frequent oil changes, 15,000 miles strikes a balance between adequate maintenance and operational efficiency for DTNA engines.
