Fuel
Saving Tips
Each issue of FuelWatch
will include fuel saving tips drawn from the world’s best
practice and from local sources who have consistently achieved ongoing
fuel savings. In this issue we have drawn on the vast practical and
technical experience of the Technology and Maintenance Council of the
American Trucking Association. Based on recommended engineering and
maintenance practices the TMC compiled a comprehensive digest to help its
members improve fuel economy. All of their suggestions and guidelines are
based on their recommended practices manual. We are grateful to the TMC
and ATA for the opportunity to pass on some excellent ideas and
suggestions.

With the growth in 6x2
trucktractor and freight carrier sales it is interesting to note the
level of improvement in fuel consumed you can expect when tag axles
are correctly selected and operated. When compared with tandem axle
drive axles the fuel saving should be between 2 and 3%. Tandem drive
axles add weight, friction and a need to overcome paristic power.
There are points to consider. Make sure traction will not be lost,
especially in bad weather and watch out for excessive tyre wear.

The TMC has carried out
in-depth studies to assess the fuel increase in fuel consumption
caused by idling. This can be as much as 10% when considering the
length of time fridge units and airconditioners are operated. To save
fuel and the environment and among other reasons, the US has strict
rules when it comes to idling. In New York, for instance, truck
drivers caught idling their engines for more than five minutes face
fines up to $1,000. In future issues we will be exploring in greater
depth the high cost of “avoidable” idling.
Drivers in the US who perform according to the following regularly
earn fuel conservation bonuses:
•
Keep to company specified speed limits
• Use cruise control whenever possible if fitted
• Coast whenever possible (only for trained drivers)
• Limit vehicle accessory use
• Consistently make smooth starts
• Use progressive shifting technique
• Limit the number of stops
• Limit engine idling
• Conduct thorough vehicle inspections
• Maintain proper tyre pressure
Following basic discipline,
pays off for driver and operator.
