Will your tank make it?
Range here uses real-world consumption — about 20% above the lab figure most cars are advertised with — and holds back a reserve rather than running you to the last drop.
| Vehicle | Real range | Fuel used | One tank? |
|---|---|---|---|
| Small car45 L tank, 6.5 L/100km | 513 km | 34 L | Yes |
| Mid-size SUV60 L tank, 8.0 L/100km | 563 km | 42 L | Yes |
| Ute or 4WD80 L tank, 9.5 L/100km | 632 km | 50 L | Yes |
Your car is not one of these three. Use your actual make and model in the planner above and OTW works it out from the manufacturer's figures and how much fuel you have right now. If you have measured your own fuel use, you can calculate your L/100 km.
