Fuel Saver AU: Petrol Prices

Stop guessing at the bowser. Enter two prices, your tank size and detour, and Fuel Saver shows instantly if the cheaper servo is worth the drive. Private & offline.

Fuel Saver AU is a simple petrol price and fuel cost calculator for Australian drivers. It answers one question fast: is it actually worth driving to a cheaper petrol station once you count the fuel you'd burn getting there?

Enter the nearby price, the cheaper station's price, your tank fill size, the extra round-trip distance and your car's fuel economy. Fuel Saver instantly shows the net saving (or loss), the break-even distance, and which station really wins.

WHY DRIVERS USE IT

• Compare two petrol prices in seconds
• See the real saving after the fuel burned driving further
• Know the maximum extra distance that still breaks even
• Works in metric or imperial, and in AUD plus other currencies
• 100% offline, with no accounts and no tracking
