Fuel costs are often top of mind for many motor carriers—especially with the recent diesel spike. The best way to cut fuel costs is to improve a tractor's fuel economy.

This episode of The Fleet Load hosts Yunsu Park, the North American Council for Freight Efficiency's (NACFE's) director of engineering, to talk about the fuel efficiency equipment and practices that make the biggest impact—and those that are popular among carriers. Park develops NACFE's Fleet Fuel Study, a regular benchmarking tool for fleets looking for fuel-saving technologies gaining traction.
