Worked examples

Same road. Now hitch the van.

Seven real routes planned twice, side by side: the car alone, and the car towing a 3.2-tonne off-road caravan. What the wind costs, what filling everywhere would have cost, and what FuelOracle saved.

Worked examples only. These plans were generated once, on a fixed date, to show how FuelOracle helps you plan better and save time and money. Prices, opening hours and wind have all changed since. Do not use them to plan a real trip: plan your own and FuelOracle will plan it on today's prices and forecast.

Does the wind matter on Nullarbor?

On 10 September it cost the caravan run $32.65 (+12.2 L). FuelOracle checks the forecast wind on each leg for the day you leave, so the same road can price differently on a different day.

What would filling up at every servo cost on this run?

$1,634.27 towing. FuelOracle's plan saves $34.46 by choosing where to fill and how much to buy, not by driving further or filling less than it needs.

Fuel burn is modelled for this rig: the van behind it, the speed it holds, the climbs and the wind on every leg. The model is checked against the rig’s real fill-ups and tuned over time. Old-school is the same driver with no planning: fill to full at every stop, and whenever the next servo is out of reach.

Example plans use official state fuel price feeds and Open-Meteo wind forecasts, captured once on 4 September 2026. Coastline from Natural Earth. FuelOracle is an independent app and does not represent a government entity.
