Who is correct regarding the longevity of synthetic oils compared to conventional oil?

The choice of Technician B is correct regarding the longevity of synthetic oils compared to conventional oils. Synthetic oils are specifically designed to provide superior performance in various engine conditions. They are made from chemically engineered compounds that offer higher resistance to breakdown and oxidation, which generally allows them to last longer between oil changes compared to conventional oils.

Synthetic oils can maintain their viscosity and effectiveness over a wider range of temperatures and stressful conditions, such as extreme heat or cold, which helps in reducing engine wear and extending the life of both the oil and the engine. In many cases, manufacturers recommend extended oil change intervals when using synthetic oils, recognizing their ability to keep engines clean and maintain performance over a longer schedule.

This ability to last longer is often attributed to their enhanced properties, such as improved lubricating qualities and the ability to better withstand the demands placed on them by modern high-performance engines or over different driving environments. Thus, Technician B’s statement aligns with industry consensus on the benefits of synthetic oils compared to their conventional counterparts.
