You can always fill up the tank yourself before returning the rental, but it's understandable if you can't:
•It's common for Sixt to charge you for the cost of refilling the tank to the right level along with a service charge if you return the rental car without the tank full. This makes sure that there are no problems when the car is ready for the next customer.
• To handle this well, you should let Sixt know ahead of time if you think you won't be able to return the car with a full tank. They might be able to give you advice on the process and any fees that go along with it, which would make things go more smoothly.
Real customer feedback is very important to us because it's the most reliable way to get advice. If you think this information is out-of-date or if you've had any problems with it, please let us know in the comments. Your contributions will help get the word out and make the whole experience better.
