Where your fleet’s fuel actually goes

Start by measuring

You can’t cut what you can’t see. Before changing anything, record a baseline for a few weeks: fuel bought, kilometres driven and mileage (km per litre) for each vehicle and each driver. Use fuel bills or a fuel card statement for litres, and the odometer or GPS for distance.

Mileage per vehicle is the number to watch. When one vehicle on a similar route returns noticeably lower mileage than the others, that is where to look first.

Idling

An engine running while the vehicle stands still burns fuel for no distance. In Indian traffic and at loading points, idle time can add up to hours a week per vehicle. Common causes are waiting at pickup points with the AC on, warming up the engine for long periods, and drivers resting in the cab with the engine running.

• Set a clear rule, for example: switch off if stopped for more than a few minutes, except in traffic.
• Track idle time per vehicle and per driver every week. GPS tracking can show engine-on-while-stationary time.
• Look at where idling happens. If it is always at one warehouse or school gate, fix the waiting process there.

Route adherence

Detours, personal trips and wrong turns add kilometres that nobody planned for. Compare the planned route and distance with what was actually driven.

• Agree an approved route for regular trips and share it with drivers.
• Use route-deviation alerts so changes are noticed the same day, not at month end.
• Review unplanned stops. Some are genuine (traffic, a road closure); patterns are worth a conversation.

Overspeed

Fuel use rises as speed rises, especially on highways, and overspeed is also the biggest safety risk. Keeping to a steady, moderate speed typically saves fuel and reduces wear on tyres and brakes.

• Set speed limits per vehicle type and road type, and alert on breaches.
• Review overspeed events weekly with each driver, with the place and time.

Harsh driving

Hard acceleration and harsh braking waste the fuel spent on getting up to speed. Smooth driving that anticipates traffic can reduce consumption noticeably, and it is safer and easier on the vehicle.

• Track harsh acceleration, harsh braking and sharp cornering events.
• Coach rather than punish: show drivers their own events and how they compare.

Tyre pressure and maintenance

Under-inflated tyres increase rolling resistance, so the engine works harder. Poorly maintained engines, clogged air filters and dragging brakes do the same.

• Check tyre pressure weekly, cold, against the manufacturer’s figure.
• Keep to the service schedule; a sudden drop in a vehicle’s mileage is often an early sign of a fault.
• Avoid carrying unnecessary weight, and keep loads within limits.

Fuel drops and theft

Fuel pilferage is a real problem for many fleets. The signs are a fall in tank level while the vehicle is parked, refuelling bills that don’t match tank level changes, or mileage that is low only for certain drivers or routes.

• Reconcile refuelling bills against distance driven every week.
• Where a fuel-level sensor is fitted, alert on sudden drops when the engine is off.
• Refuel at fixed, trusted stations where possible, and keep receipts.

Driver scorecards

A simple weekly scorecard turns all of the above into one conversation. Score each driver on idle time, overspeed, harsh driving and route adherence, and share the score with them. Most drivers improve once they can see their own numbers, and recognising the best drivers works better than only flagging the worst.

A 30-day plan

1. Week 1: record a baseline of fuel, distance and mileage per vehicle and driver.
2. Week 2: agree rules for idling, speed and routes, and explain them to drivers.
3. Week 3: start weekly scorecards, and check tyre pressure across the fleet.
4. Week 4: compare mileage with the baseline, and follow up on the vehicles that did not improve.
