How to Cut Fuel Costs on Delivery Routes

Fuel is one of the few costs a distributor sees every single day. It is also one of the easiest to misread. Most fleets don't waste fuel because drivers are careless. They waste it because the plan sends trucks on more kilometres, at worse times, with less on board than necessary.

This guide shows where fuel actually goes on delivery routes and what you can change, starting with fixes that need nothing more than a map, a spreadsheet and a conversation with your drivers.

Where the fuel actually goes

Before cutting anything, it helps to know which leaks you have. On most distribution routes, the same handful show up again and again.

Empty and unnecessary kilometres

Every kilometre a truck drives without delivering is pure cost: the run out to the first customer, the drive back to the depot, detours to pick something up that should have been loaded in the morning. These "empty kilometres" are often a larger share of the day than people expect.

Bad stop order and zig-zagging

A route that visits stops in the order the orders came in, or in alphabetical order, almost always crosses itself. The classic sign is two trucks working the same neighbourhood on the same day, or one truck that visits the north side, goes south, then comes back north for a customer it missed.

Waiting and returning to closed customers

A driver who arrives at a café before it opens either waits with the engine running or leaves and comes back later. Both burn fuel. A failed delivery is worse: the goods ride around all day and need a second trip tomorrow.

Rush-hour crawling

Stop-and-go traffic is the least efficient way to move a heavy truck. A route that is short on the map can use more fuel than a longer one if it sits in city traffic at 8:00 or 17:00.

Half-empty trucks

Sending three trucks out at 60 % load usually costs more than two trucks well loaded. Each extra truck brings its own empty kilometres to and from the delivery area.

Extra trips for forgotten or rushed orders

"Can you just drop this off?" Small urgent runs for a forgotten case or a late order are some of the most expensive kilometres you drive, because the whole trip serves one customer.

Practical fixes that work

1. Plan by area, then sequence properly

Group customers into delivery zones that make geographic sense: by district, along main roads, or by side of the river. Assign each truck one area per day instead of scattering its stops across the map.

Then put the stops in a sensible order within the zone. A simple test: draw the route on a map. If the line crosses itself, there is almost always a shorter order.

2. Fill trucks by weight and volume, not by stop count

Load planning and route planning are the same problem. Check both limits for each vehicle:

• Weight runs out first with drinks, building materials and other heavy goods.
• Volume runs out first with bulky, light items such as packaging or snacks.
• Pickups such as empties, returns or pallets take capacity too, so count them in the load.

A truck that is genuinely full on a tight route is your cheapest delivery.

3. Compare running one truck fewer

Before dispatching, ask a simple question: could the same orders be delivered with one truck less, while still respecting delivery windows and shift lengths? Sometimes the answer is no. But when it is yes, you save a whole vehicle's empty kilometres, not just a few detours. Compare total kilometres and total hours for both options, not only the number of trucks.

4. Avoid rush hours where windows allow

Not every customer needs a morning slot. Look at your list and identify who can take goods mid-morning or early afternoon. Move those stops out of the peak, and route trucks so they leave the city centre before traffic builds.

5. Cut failed deliveries with windows and notifications

Every closed door is a wasted stop and a second trip. Two things help a lot:

• Record receiving hours for each customer and plan around them, not around your own convenience.
• Tell customers when you are coming. A short message with a delivery window the day before or in the morning lets them have someone ready, or warn you that they are closed.

6. Consolidate small orders and delivery days

If a customer orders small amounts four times a week, ask whether two deliveries would work just as well. Fixed delivery days per area ("north on Tuesdays and Fridays") make trucks fuller and routes denser. Set a minimum order value or a cut-off time for next-day delivery so urgent single-customer runs become the exception.

7. Driving style and idling

Drivers matter, even if the plan matters more. A few habits that make a difference:

• Switch off the engine while unloading and waiting.
• Accelerate smoothly and anticipate traffic lights and junctions.
• Keep to sensible speeds on main roads; fuel use rises sharply at higher speeds.
• Don't carry unnecessary weight that stays on the truck all week.

Share these as practical tips, not as blame. Drivers usually know where the plan forces them to waste fuel.

8. Tyres and maintenance basics

Under-inflated tyres increase rolling resistance, and clogged air filters, misaligned wheels or overdue servicing all quietly increase consumption. Put tyre pressure checks on a weekly schedule and keep service intervals on track.

How to measure fuel per stop and per route kilometre

You can't manage what you don't measure. Fuel cards and odometer readings are enough to start.

1. Fuel per 100 km for each truck. Track litres refuelled against kilometres driven. A truck that suddenly uses more may need maintenance or may be running different routes.
2. Kilometres per stop. Divide total route kilometres by the number of completed deliveries. This is the best single sign of how tight your routes are.
3. Fuel cost per stop. Fuel cost for the day divided by completed stops. Example: if a truck uses 60 litres at €1.70 for 30 stops, fuel cost is €3.40 per stop. (Illustrative numbers only.)
4. Load factor. How full was the truck when it left, by weight or volume?
5. Failed deliveries. Count them, and note the reason: closed, nobody available, wrong address.

Review these monthly, by route or by area. When you change something, such as new zones or different delivery days, you will see whether kilometres per stop really went down.

Where software helps

All of the above can be done by hand, but sequencing dozens of stops with time windows and truck capacity every day is where manual planning breaks down. That's what tools like BeeRoutes are built for.

With BeeRoutes route optimization, you plan the day in one click, taking into account time windows and receiving hours, truck weight and volume capacity, pickups in the load, shifts and breaks, and rush-hour traffic measured for your area. You can set up delivery zones and several depots, and compare plans with fewer or more trucks before dispatching, with kilometres and hours shown for each plan. On the standard Solomon benchmark, the optimizer stays on average within about 1 % of the best-known solutions.

Customers get a one-hour delivery window by email or SMS, which means fewer closed doors. Drivers follow the route in the app with built-in voice navigation, and the office sees progress on a live map.

Plans start from €49 per month for 3 trucks; see pricing for details. If you want to see what your own routes look like when optimized, start a free 14-day trial, no card needed.
