Navigating Australia's vast and varied roads, from bustling urban highways to serene coastal paths, can be a journey of discovery. Yet, one ever-looming question remains: "How much will this trip cost in fuel?"

Traditional methods of estimating fuel costs can be cumbersome and error-prone. But worry not; our state-of-the-art app is here to change the game. Here's how:

The Old Versus the New: Simplifying Fuel Calculations

The Manual Method

Traditionally, estimating fuel expenses required a few steps:

  1. Research your car model's average fuel efficiency.
  2. Monitor ever-fluctuating fuel prices across different regions.
  3. Calculate the expected distance of your journey.
  4. Crunch the numbers using a somewhat convoluted formula.

While this method can provide a ballpark figure, it can be time-consuming and leaves room for inaccuracies, especially if you're not using the latest data.

Roadtrip's Approach

Forget the hassle of manual calculations. With our app, fuel cost predictions are as easy as 1-2-3:

  1. Input the basics: Simply type in your journey's origin, destination, and your car model.
  2. Let the app work its magic: Leveraging an extensive database of current petrol, diesel, and electricity prices, alongside accurate fuel consumption data for a wide range of vehicles, the app instantly provides an estimate.
  3. Get comprehensive results: See the fuel cost break-down based on the type of energy your vehicle uses.
