Reduce Speed: Speeding eats up fuel and increases wear on the engine and driveline. High-speed driving also reduces tire life. Generally for every 10 km/h above 90 km/h you burn about 10 percent more fuel.
Use Cruise Control: Using cruise control on the highway helps to maintain a constant speed which saves fuel. Note that cruise control is not efficient or safe on roads that are slippery or that have sharp corners or steep hills.
Decrease Idling: Shut the vehicle off when you stop for any length of time. This will save fuel and reduce maintenance costs. Idling an engine wastes about 3 litres of fuel per hour (.8 gallons).
Use Progressive Shifting Techniques: Progressive shifting is shifting before you reach the maximum governed rpm. It means making an up-shift using only enough rpm to get into the next highest gear and still pull the load.
Maintain Proper Tire Inflation Pressure: Under-inflation increases fuel consumption by 1 percent for every 10 psi on all tires. There is also a 15 percent tread wear penalty for every 10 psi under-inflated. Tire pressure should be checked at least once a week with an accurate gauge.
Tractor-trailer Gap: A large gap can increase fuel consumption by three to five percent. Limit the tractor-trailer gap to about 64 cm (25 inches) where possible.
Conduct Inspections: Besides being a legal requirement, inspections help you find problems that can cause accidents, breakdowns, and poor fuel efficiency from your equipment.
