7 effective ways to manage fuel consumption in your fleet, data-driven strategies for UK operators

Fuel costs typically represent 25 to 35% of total fleet operating expenses for UK commercial vehicle operators. Maximising fuel efficiency from existing fleet assets is one of the most commercially impactful things a fleet manager can do. LockCar 4G GPS tracking and the LFM Fleet Monitoring Platform provides the data infrastructure for all seven of these strategies.

Strategy 1, eliminate excessive idling

Idling consumes fuel at approximately 0.8 litres per hour for a typical diesel van. A driver who idles for 45 minutes per day wastes over 200 litres per year. LockCar GPS logs idle time per vehicle and driver, enabling targeted coaching or operational changes such as improved delivery scheduling to reduce waiting time.

Strategy 2, reduce speeding and high-speed cruising

Fuel consumption increases significantly above 60 mph. A van at 70 mph uses approximately 25% more fuel than at 60 mph. LockCar speed monitoring logs every instance of a vehicle exceeding a configurable threshold. Coaching drivers to adopt slower motorway cruising speeds produces measurable fuel improvements within weeks.

Strategy 3, coach out harsh acceleration and braking

Aggressive driving wastes fuel at both ends of the speed range. Rapid acceleration from stops and harsh braking into stops both discard kinetic energy. LockCar driver behaviour reports identify drivers with above-average harsh event rates. Targeted coaching based on specific data points produces faster and more sustained improvement than general instruction.

Strategy 4, optimise routes to reduce total mileage

Unnecessary mileage is direct fuel waste. LockCar trip history data allows fleet managers to review planned versus actual routes and identify where drivers are deviating or making unnecessary return trips. Route optimisation using historical GPS data typically identifies 10 to 15% of total mileage as reducible through better planning.

Strategy 5, right-size the fleet

Underutilised vehicles add directly to fleet fuel costs. LockCar utilisation data shows which vehicles in the fleet are covering the highest and lowest mileages and whether utilisation patterns suggest a mismatch between fleet size and operational demand. Right-sizing the fleet based on actual utilisation data reduces total fuel consumption proportionally.

Strategy 6, maintain tyre pressure and service compliance

Under-inflated tyres increase rolling resistance and fuel consumption by 2 to 4% per 10 PSI below optimal pressure. LockCar maintenance scheduling integration reminds fleet managers of service due dates for each vehicle. Maintaining correct tyre pressures and timely servicing keeps every vehicle operating at its designed efficiency.

Strategy 7, benchmark driver performance and incentivise improvement

When drivers know their fuel efficiency data is being measured and compared, and performance is linked to recognition or incentives, fuel consumption improvements are sustained over time rather than being temporary responses to a coaching conversation. LockCar LFM produces the per-driver data required to run meaningful performance benchmarking.
