Should you prepay for rental car fuel?
Prepaid fuel is a convenience option to evaluate against your actual route. Check how the charge works and what happens to fuel remaining at return.
Compare self-refuelling through Returning a rental car under a full-to-full fuel policy, then put the chosen option into How to build a complete car hire trip budget.
Compare the stated options
Ask for the prepaid amount, the fuel quantity it represents and the refund rule, if any. Compare that with refuelling yourself and with the supplier’s recharge or refuelling service if you do not. Do not assume an unused portion will be refunded.
Use a realistic final-day plan
For a short local rental, much of a prepaid tank might remain unused. For a long route with a difficult final refill, convenience may matter more. Make the choice using your expected usage and schedule, and keep enough fuel to return safely rather than trying to achieve an exact empty tank.
Test prepaid fuel against a short local trip
If the rental covers only a few local journeys, much of a prepaid tank may remain unused. Ask how that remainder is treated. Compare the actual prepaid charge with your likely consumption and final refuelling plan; do not assume that convenience means the lowest cost or that unused fuel is refunded.
