What is one benefit of using synthetic oil in DTNA engines?

Using synthetic oil in DTNA engines enhances performance in extreme temperatures, which is a significant benefit. Synthetic oils are engineered to provide better lubrication and protection under both high and low temperature conditions compared to conventional oils. In extremely high temperatures, synthetic oils maintain their viscosity, ensuring that the engine components remain well-lubricated and protected against wear and tear. In cold temperatures, synthetic oils flow more easily than conventional oils, providing better protection during start-up and reducing engine wear. This temperature stability contributes to improved engine efficiency, performance, and longevity, making synthetic oils a preferred choice for many heavy-duty and high-performance engine applications.

The other options do not accurately describe the benefits of synthetic oil. For instance, synthetic oils typically come at a higher cost than conventional oils, and they usually have a longer change interval, so they do not require more frequent changes. Additionally, the use of synthetic oil does not directly affect engine size; rather, it is focused on improving performance and protection.
