10 steps toward better fuel economy

1. Maintenance matters

2. Maintain proper tire inflation for both the trailer and tractor.
3. Replace fuel filters at proper intervals.
4. Keep all axles properly aligned to minimize rolling resistance.
5. Repair body damage, dings, dents and loose fairing that may create additional drag.
6. Use good synthetic lubricants in the transmission and axles.

7. Slow down. Fuel economy improves when a 60 MPH cruise speed is maintained.
8. Use a fuel economy display device that permits monitoring so drivers may correct fuel economy performance by the minute.
9. Use of cruise control will typically enhance fuel economy performance.
10. Maintain optimal RPMs for the specific engine. Each engine has a unique torque curve, typically between 1,200 and 1,600 RPMs.
11. Minimize idling. Five minutes of warm-up is generally adequate and cool-down comes when a truck pulls in to park. Depending on its speed, idling uses between 0.5 and 1.2 gallons per hour.
