Fuel cost calculator questions
How is the trip fuel cost calculated?
Litres needed = km ÷ 100 × L/100km. Fuel cost = litres × cents per litre ÷ 100. A return trip doubles the one-way distance.
What does petrol or diesel cost per km?
Multiply the L/100km by the cents per litre and divide by 100 for the cents per km. At 8.0 L/100km and the national U91 average of 230.0c a litre on 10 Nov, a km costs 18.4c, so a 450 km trip uses 36 litres and costs $82.80. Diesel works the same way at its own price.
Can FuelRadar calculate the driving distance?
Yes. Choose Start and destination, pick both places from the suggestions, then use the driving distance. FuelRadar fills the distance and, when stations on the route have current reports, their average price. You can change either figure.
Where do I find my vehicle’s fuel use?
Use the average from recent fills or the trip computer. The vehicle options are typical figures; traffic, towing, speed and load change what your car uses.
How do I get a better price for the trip?
Check station prices on the fuel map before you leave, and time a bigger fill with the price cycle charts where your city has a cycle.
Can I enter fuel use in km/L or MPG?
Yes. Choose My own fuel use, then pick L/100km, km/L, MPG (US) or MPG (UK) beside it. The calculator converts it to L/100km (100 ÷ km/L, 235.2 ÷ US MPG or 282.5 ÷ UK MPG) and the breakdown shows your figure in every unit.
How do I split the fuel cost between passengers?
Set People sharing and choose Return. At the U91 average above, a 450 km trip there and back in a medium car costs $55.20 each for three people.
Can I share or save an estimate?
Yes. Once you change a figure, the page address carries the distance, car, fuel type, price, people and return trip, so the link opens the same estimate. It never includes your start, destination or location.
