How to reduce fuel losses in your fleet

Fuel is one of the biggest costs of running vehicles, and it is also one of the easiest to lose track of. Fuel disappears in a few predictable ways. If you know where to look, you can close most of the gaps.

1. Know your baseline

You cannot spot a loss if you do not know what normal looks like. Record fuel added, distance covered and the job done for every vehicle. Divide to find the fuel used per distance, and note what is typical for each vehicle and route.

2. Watch for theft and leakage

Unexplained drops in the tank, or a vehicle that suddenly uses more than before, are warning signs. Practical steps include locking fuel caps, keeping a signed record every time fuel is added, and using fuel monitoring sensors that show the level in the tank over time.

3. Coach driving habits

• Cut unnecessary idling.
• Avoid harsh acceleration and hard braking.
• Keep to sensible speeds.
• Do not overload vehicles.

Sharing simple results with drivers, and recognising the ones doing well, usually works better than blame.

4. Keep vehicles healthy

A poorly maintained vehicle burns more fuel. Correct tyre pressure, clean air filters and regular servicing all help. Our preventive maintenance checklist is a good starting point.

5. Plan trips and routes

Empty runs and unnecessary detours waste fuel. Combine deliveries or pick-ups where you can, plan routes before leaving, and use tracking data to see where time and distance are being lost.

6. Review every month

Set a regular time to compare vehicles and drivers against the baseline. Look at the ones that stand out in either direction, find out why, and fix what you can. Small gains repeated every month add up.

A simple example you can copy

Suppose a vehicle covers 500 kilometres in a week and uses 60 litres. That works out at 12 litres for every 100 kilometres. If the following week it covers the same distance and uses 75 litres, something has changed. It might be a fault, a different driver, a different route or fuel going missing. The point is not the exact numbers, it is that a regular record makes the change obvious and gives you a place to start asking questions.

Warning signs worth acting on

• A sudden rise in fuel use with no change in the work being done.
• Fuel added more often than the distance covered would explain.
• A vehicle that runs for long periods with the engine on but is not moving.
• Tank levels that fall while the vehicle is parked.

When you see one of these, check the vehicle, the paperwork and the route, and talk to the driver before drawing conclusions.
