How to Save Truck Diesel and Eliminate Engine Fuel Theft

Diesel fuel is the largest expense component in logistics truck operations, accounting for up to 30–40% of total Operational Expenditure (OPEX). Therefore, even small savings in diesel fuel consumption on each trip can generate budget savings of up to millions of Rupiah per month. To achieve this, companies need to address two primary sources of inefficiency: waste due to driving style and engine condition, and diesel fuel leakage due to theft, using a holistic approach encompassing technical, human, and technological aspects to sustainably maintain and secure fleet profit margins.

Pillar 1: Technical and Maintenance Strategy (Vehicle Optimization)

A truck’s physical condition directly impacts fuel efficiency and operational performance. Components such as the engine, tires, and transmission system that are in poor condition will significantly increase diesel consumption. Therefore, technical strategies and vehicle optimization are crucial for maintaining optimal truck performance and fuel efficiency. Here are some examples of technical strategies:

Scheduled Machine Maintenance (Preventive Maintenance)

• Carry out regular machine checks and maintenance according to schedule.
• Replace the fuel filter, air filter, and engine oil on time (regularly)

• Engines with optimal combustion consume less diesel fuel.
• A “healthy” (well-maintained) engine can save up to 10% on diesel fuel.

Tire Management and Air Pressure

• Check and monitor tire air pressure regularly.
• Ensure ideal tire pressure according to standards and load

• Low tire pressure will increase friction (rolling resistance) and force the engine to pull the load harder.
• It is mandatory to carry out a visual check before the trip (P2H)

Weight and Aerodynamic Optimization

• Avoid overloading as it will increase the engine’s power requirements exponentially.
• Make sure the tarpaulin or container cover is tightly and neatly installed to reduce wind resistance.

Pillar 2: Managerial and Driver Strategies (Safe & Economical Behavior)

In addition to technical aspects and vehicle physical condition, human factors also play a significant role in fleet operational efficiency. Uncontrolled driving and inefficient route selection can lead to excessive fuel consumption that exceeds initial estimates. Therefore, managerial and driver strategies are crucial components in optimally controlling diesel consumption. Here are some examples of managerial and driver strategies:

Anti-Idling Policy

• Implement strict policies regarding idling time (Anti-Idling)
• If the truck stops for more than 3-5 minutes while waiting for loading and unloading (rest), the engine must be turned off.
• Idling time can consume 1-3 liters of diesel per hour

Eco-Driving Training and Efficient Driving Style

• Focus on driving style with smooth acceleration and anticipatory braking.
• Trucks must be run at optimal RPM (revolutions per minute) (sweet spot)
• This strategy must be integrated with the Fleet Management System because these habits must be measured accurately, not assumed.

Intelligent Route Planning (Route Optimization)

• Using advanced technology to determine the best route based on various conditions and accurate calculations.
• Following the route determined by the system (not the driver’s initiative)
• The shortest route does not necessarily mean the fastest or most fuel efficient route.

Pillar 3: Technology Solutions to Secure Truck Diesel

Saving truck diesel fuel and securing it are top priorities in logistics operations given the high potential for loss due to theft and undetected waste, which can lead to unplanned expenses and reduced profit margins. In this digital era, TransTRACK’s Fleet Management System offers a technological solution that accurately monitors fuel volumes and detects any unusual decreases. Here are some of the advantages of TransTRACK’s Fleet Management System:

Precision Fuel Sensor (Fuel Monitoring System)

• Role: The capacitive sensor installed in the tank provides real-time and accurate diesel volume data.
• Benefit:Detects abnormal reduction in diesel fuel (indication of theft or diesel fuel fraud) and prevents manipulation of fuel filling receipts.

Real-Time Driver Behavior Monitoring

• Role: This technology accurately records every driver behavior, from speeding to harsh braking, and records the duration of idling time per driver.
• Benefit: Generates an objective Driver Score to determine savings or retraining bonuses for drivers.

Automatic Solar Performance Report

• Role:The Fleet Management System provides reports on liters/km or km/liter per driver and per truck, making it easier for companies to compare efficiency and identify wasteful drivers or truck units.

Conclusion

Saving diesel fuel on trucks cannot be achieved with a single approach, but rather through a combination of disciplined operational policies, optimal machine maintenance, and the use of appropriate technology. Real-time technologies such as Fuel Monitoring in Fleet Management System play a crucial role in accurately monitoring fuel consumption and detecting potential misuse or theft. By collaborating with human, technical, and system monitoring factors, operational efficiency can be improved while maintaining company profit margins.
