Essential Tips for Commercial Vehicles

Fuel costs in South Africa continue to rise, making fuel efficiency a top priority for fleet operators and commercial vehicle owners. By implementing smart strategies, businesses can save significantly while reducing their carbon footprint.

Here are practical ways to improve fuel economy and get the most out of every drop of fuel.

Maintain Proper Tyre Pressure

Underinflated tyres increase rolling resistance, making the engine work harder and burn more fuel. To enhance efficiency:

• • Check the tyre pressure regularly and maintain manufacturer-recommended levels.
  • Use high-quality, durable tyres suited for South African road conditions.
  • Rotate and align tyres periodically to ensure even wear and better handling, especially on rough or gravel roads.

Regular Servicing and Maintenance of the Engine

Routine servicing is essential to keep commercial vehicles running efficiently. A well-maintained engine consumes less fuel and lasts longer. Our best maintenance tips include: 

• • Regular oil changes using SABS-approved lubricants.
  • Inspecting and replacing worn-out spark plugs and fuel injectors.
  • Cleaning the air intake system to ensure optimal airflow.
  • Checking for oil or fuel leaks that could impact performance.

Use High-Quality Filters

Filters play a crucial role in fuel efficiency by ensuring clean air, oil, and fuel flow. Filters provide premium filtration solutions designed for South African conditions. Your vehicle relies on several essential filters to maintain optimal performance and efficiency. Below, we explore the different types of filters in your car and their functions. For superior protection and reliability, we recommend Fleetguard filters.

• Fuel Filters

Fleetguard fuel filters remove contaminants such as dirt, debris, and water from diesel fuel, preventing injector clogging and maintaining optimal engine performance. Clean fuel enhances combustion and reduces unnecessary fuel consumption.

• Air Filters

Dusty roads, especially in rural and mining areas, can clog air filters quickly. Fleetguard air filters improve airflow, ensuring proper fuel combustion and enhancing overall fuel economy.

• Oil Filters

Efficient lubrication minimises engine friction, reducing wear and fuel consumption. Fleetguard oil filters help remove impurities, keeping engine oil clean for extended performance and efficiency.

Reduce Excessive Idling

Idling wastes fuel and increases engine wear. In South Africa, where long-haul trucking is common, minimising idling can lead to substantial fuel savings. Consider:

• • Switching off the engine during prolonged stops, such as border posts or loading zones.
  • Utilising automatic engine shutdown timers to turn off the engine after a set period of idling, reducing unnecessary fuel consumption.
  • Implementing anti-idling policies for fleet drivers.

Optimise Driving Habits

Driver behaviour directly impacts fuel efficiency. Training drivers in fuel-conscious habits can improve overall fuel savings. Our team: 

• • Maintains steady speeds and avoid aggressive acceleration.
  • Use cruise control on long-distance routes where safe.
  • Avoid excessive braking by anticipating traffic conditions.
  • Shift gears efficiently in manual transmissions, especially when navigating hills and mountain passes.

Manage Vehicle Load and Aerodynamics

Heavy and poorly loaded trucks consume more fuel. To maximise efficiency:

• • Remove unnecessary cargo or equipment.
  • Use aerodynamic modifications such as roof deflectors and side skirts for better fuel savings.
  • Ensure even load distribution to minimise resistance.

Plan Efficient Routes

South Africa’s road infrastructure presents challenges such as toll gates, congestion, and poorly maintained roads. Route planning can help mitigate these issues and save fuel. We suggest that you:

• • Use GPS and fleet management systems to identify the most efficient routes.
  • Avoid high-traffic areas and unnecessary toll roads where possible.
  • Plan deliveries strategically to consolidate trips and reduce empty return trips.

Improving fuel efficiency in commercial vehicles requires a combination of proactive maintenance, high-quality components, and strategic driving habits. By implementing these strategies, fleet operators can achieve significant cost savings while contributing to a more sustainable transport industry.
