More about this answer
80 drops · 54 miles in total including 8 back to the depot · starting at 80% on the fuel gauge.
80 drops over 40 delivery-round miles — about 0.5 miles between drops at 19 mph average.
6 miles from depot to first drop, counted once.
Plus 8 miles back to the depot after the last drop: 54 miles modelled in total.
About 6.9 litres for the round, 70% of the tank left at the depot.
About 8.2 hours modelled from driving and the supplied dwell time; statutory breaks and loading time are not added.
The same round costs a diesel more per mile than its motorway figures suggest — stop-start is its worst case and an electric van's best.
About £10.44 of fuel for the round using the hand-maintained pump assumption.

Supplied facts: 80 drops; 6 miles to first drop; 40 delivery-round miles; 8 return miles; 600 kg starting load; 80% starting fuel gauge.
80 drops over 54 miles including 8 back to the depot, averaging 0.5 miles a hop at about 19 mph, starting at 80%.
Assumptions: 4 minutes dwell per stop (8.2 hours modelled duty); 50% average load carried; standard parcel duty; normal traffic; neutral weather.
Stop-start driving +13% — Stop-start driving at 19 mph average is where a combustion engine is least efficient — idling and pulling away burn fuel with nothing recovered. Calibrated for this vehicle class at up to 22%.
Payload emptying across the round +4% — 600 kg leaves the depot and the selected load profile treats 50% as carried on average (300 kg). A full-load assumption would add 7%.
Transparent physics and hand-maintained assumptions. No trained model is used.

Same round, same class — electric comparison
Vauxhall Vivaro Electric 75kWh — 20.8 kWh · about £6.87
The electric equivalent gains from exactly the stop-start work this diesel loses on, so a round like this is a more favourable electric case than motorway-rate figures suggest.
Efficiency assumptions and prices here are hand-maintained working figures, not live market rates or measured telemetry. Check them before relying on them.
