The fuel math: Hertz vs Sixt
Both brands use the same trick — return below full and pay $9.49 to $11.75 per gallon (about 3× retail). On a 15-gallon tank returned half-empty:
- Hertz: 7.5 × $9.49 = $71.17 in refueling charges
- Sixt: 7.5 × $11.75 = $88.13 in refueling charges
- Self-fill (either brand): 7.5 × $3.65 = $27.38 at the pump
Both brands' refueling fees can be avoided by returning the car at the right fuel level. FillItRight calculates the exact gallons to add for any brand and any vehicle.
