Fuel costs are not included in the rental price. You must therefore return the vehicle with the same amount of fuel as it had at the start of the rental.
If the fuel level is lower at check-out, the owner can make an adjustment to be compensated for the difference.
If the fuel level is higher at check-out, you can make an adjustment yourself, if the owner didn't take care of it for you.
NB: For Getaround Connect rentals with automatic fuel adjustments, you will be charged an additional £0,60 per missing litre for the refill service.
