Fuel cost out of control

Costo carburante fuori controllo · Transport · Beginner

The case

Your fleet of 25 trucks burns 480,000 €/year in diesel, 32% of operating costs. In the last 6 months cost per km rose 14%, but you notice huge gaps between drivers: the best do 3.4 km/litre, the worst 2.6 on the same routes. You have no reliable telematics or centralised refuelling policy. The director asks for a plan to cut fuel spend 8% in 6 months. Where do you start?
