How to Save Truck Fuel?

Fuel costs account for about 30% of total truck fleet maintenance costs. Research has collected recommendations from many experts, drivers and trucking company owners. This information, specifically for truck drivers and owners, has formulated ten easy ways to optimize truck performance and fuel economy.

Top 10 ways to save truck fuel

  1. When driving a truck, smooth braking is one of the main factors in fuel economy. When braking, kinetic energy is converted into unnecessary heat, so the driver must be prepared for potential hazards and take preventive measures so that the brake pedal has to be pressed as little as possible and with minimal effort.

  2. Tire wear and maintenance play a critical role in the operation of trucks. Low-pressure increases rolling resistance and fuel consumption. Optimum pressure and good grip guarantee safety and fuel economy. Tires should be inspected and checked regularly.

  3. Many truck driving schools wishing to optimize their vehicles must implement the most advanced technology. Incorporated FleetBoard analysis into their processes and started using Mobil Delvac 1 oils. As a result, they were able to improve fuel economy by 6% in six months.

  4. The truck’s speed while driving on flat terrain should be used to overcome uneven and hilly sections of the road with the least fuel consumption. Inertial motion can provide tangible benefits. It makes sense to calculate maneuvers in advance, especially if there is a circular movement ahead, a turn, an exit, etc., and less often to slow down and use the terrain to require as little energy as possible.

  5. The clutch pedal is your best friend and fuel economy assistant. Research shows that each upshift results in nearly 30% fuel economy. Therefore, drive-in as high a gear as possible and, if necessary, upshift through one. With proper use of the clutch, the engine should not run at high revs unnecessarily: they only entail increased fuel consumption and engine wear. Also, in most trucks, especially modern ones, the double-clutch release is unnecessary and only increases fuel consumption.

  6. Alan Virgo, a winner of the first Mobil Delvac 1 competition for McLaren Racing’s most fuel-efficient truck drivers, says that changing his driving style and incorporating Euro VI technology has allowed him to zero idle fuel consumption and drive the truck at optimum performance. Speed in terms of savings.

  7. Drivers should strive to find the speed at which fuel consumption is optimal and, if possible, maintain it. The engine has a zone of optimal rpm - this is the name for the rpm at which it works as efficiently as possible. Usually, this is no more than 1500 rpm. The manufacturer will provide you with detailed information about your truck’s engine’s characteristics and the zone of optimal revolutions.

  8. Many trucking companies make a big mistake when choosing engine oil for their vehicles. High-performance engine oil helps optimize truck performance and improve fuel economy. This statement is proved by the recent independent tests carried out by the British company Millbrook - one of the world leaders in vehicle testing and development.

  9. However, it’s not just engine oil that affects truck performance. Freight carriers should also remember that a lot depends on the oil in the transmission and rear axle.

  10. The braking system plays a vital role in the truck’s operation, but if the vehicle is equipped with a retarder, use it whenever possible to reduce brake pads wear. Retarders are especially useful for reducing or maintaining a constant speed on slopes, as they help maintain control by preventing the vehicle from accelerating.


They prevent premature wear and reduced brake pad performance, which are inevitable with heavy use of friction brakes, and can significantly increase the brake system’s life.
