260 Fuel Economy Driving
Service and Maintenance
A modern heavy-duty vehicle requires
regular and preventive maintenance to ensure
that all its components function as they
should. Use the recommended preventive
maintenance (PM) program that Volvo
Trucks North America, Inc. has developed
for the vehicles. This ensures optimal energy
efficiency from all components that are
important to fuel consumption.
Tires
If the tire pressure is too low, the rolling
resistance increases and, thereby, increases
the fuel consumption. The overall economy
is also affected as tire wear increases
considerably.
Brakes
Dragging brakes increase fuel consumption.
They should be checked regularly. It is
important that the release action of the air
valves is fast and that the moving parts
of the wheel brakes are checked for good
adjustment and operation.
