An important factor in fuel economy is route management. In terms of trucking operations, most trucking firms squeeze as much shipment of goods as possible to deliver them in a strategic way that saves time and fuel. Modern trucking companies are employing GPS and software that aid trucks and rigs in efficiently reducing fuel usage. Computer programs give out intelligent analyses on alternative routes and scheduled stops. Other new technologies being used by trucking firms include tire inflation for optimum tire performance and hybrid truck engines.

Speaking of fuel, most trucking firms buy their fuel supply from states where diesel is not as expensive as in others. States where diesel fuel is cheap include:

• Delaware
• New Jersey
• Missouri
• Oklahoma
• South Carolina
• Maryland
• Pennsylvania
• Kansas
• Iowa
• Virginia

The following cities offer the cheapest rate on diesel and other petroleum products:

• Oklahoma
• Des Moines
• Houston
• Wichita
• St. Louis
• Trenton
• Wilmington
• Baltimore
• Dallas
• Tucson

Trucking companies and firms understand that gas prices vary and may have a 20% differential within just a few blocks. In extreme cases, trucking firms even purchase their diesel supply in certain regions where their legal operating authority and BOC-3 are not honored, such as Mexico.

Fuel wastage is also caused by drag. In fact, at least 50% of the power generated by a truck is utilized to overcome drag at highway speeds. Reducing aerodynamic drag can definitely save energy and this can be achieved by: selecting a sleeper package appropriate for the trailer; aerodynamic treatment like roof fairing for use with van trailers, chassis and trailer fairings, cab extenders and aerodynamic mirrors; removal of accessory components from the air stream if possible; and wheelbase and fifth wheel settings.

Finally, correct driver behavior and proper truck maintenance also come into play. The truck driver must avoid excessive speeding and idling to save on fuel. The use of the fuel economy display also helps monitor usage. To keep a truck in good condition, make sure to: maintain correct tire inflation pressure; change air and fuel filters at the appropriate intervals; and keep drive and steer axles properly aligned to reduce rolling resistance. Monitor fuel quality at the pump; dirty fuel causes the fuel injectors to clog or exhibit improper spray pattern.

The use of aluminum flooring for trucks is also an efficient way to cut cost without sacrificing performance. Since aluminum is a lighter material, a truck or rig can accommodate greater loads of shipment while spending less on fuel.

The trucking industry may be dampened by the rise of fuel costs and the surfacing of environmental issues, but with the latest trends and improvements on truck navigation, operation, and fuel efficiency, it is safe to say that trucks and rigs will remain a huge part of the American highway for years to come.
