### Pre-Purchase vs. Gas Station Fueling

Pre-purchasing fuel can seem like a convenient option, but it may not always be the most cost-effective choice. If you don't use all of the pre-purchased fuel, you won't receive a refund. On the other hand, filling up at a nearby gas station allows you to pay only for the fuel you need.

To avoid this extra fee, it's essential to fill up at a nearby gas station before returning the vehicle.
