Most Indie Campers vehicles run on diesel. Some run on unleaded petrol — this is more common on our vehicles in the US.
You can't tell the fuel type from the model, so always check your own van before your first fill-up. The fuel type is shown on a label at the fuel filler cap, in your booking details, and on the vehicle at pick-up. If you're ever unsure, ask us before filling — it's much easier than fixing a wrong fill.
For how much fuel your van uses and what to expect on longer trips, see What is the consumption of the fuel and LPG/propane/butane tanks?
