correct engine oil for car_trailer operation

The design of semi trailers has evolved dramatically over the years. The introduction of lightweight materials such as aluminum and advanced composites has made modern semi trailers not only more robust but also significantly lighter. This weight reduction translates to increased cargo capacity and improved fuel efficiency. Moreover, aerodynamic designs are becoming the norm, enabling trailers to cut through the air more efficiently, reducing drag and, consequently, fuel consumption. This innovation is critical in an industry where fuel prices can significantly affect operational costs.
