Fuel policies remain one of the most debated topics in car rental, with headlines often labelling them as confusing or unfair. The reality? If you know what each policy means before you book, you can avoid nasty surprises at the counter.
At Rhino Car Hire, we break down the different fuel options available in 2025 so you can choose the one that best fits your trip – whether you value cost savings or pure convenience.
The Main Car Hire Fuel Policies
Full to Full (Best Value)
-
How it works: Collect the car full, return it full.
-
Pros: Pay local pump prices only, no hidden surcharges.
-
Cons: You must find a petrol station before drop-off.
-
Who it suits: Budget-savvy travellers who don’t mind planning a refuel.
Tips
-
Check the gauge shows “full” when you collect.
-
Keep receipts from your last refuel in case of disputes.
-
Look for a station near the airport before your return.
Full to Empty (No Refund)
-
How it works: You prepay a full tank (at inflated rates), return it as empty as you like.
-
Pros: No need to refuel before dropping off.
-
Cons: Often double the local fuel price, no refund for unused fuel.
-
Who it suits: Travellers who prioritise convenience, especially on long trips where you’ll burn through a full tank.
Full to Empty (Partial Refund)
-
How it works: Prepay a full tank, get a partial refund for unused fuel (often in ¼ tank increments).
-
Pros: Slightly fairer than the standard full-to-empty.
-
Cons: Refund is usually at pump rate, not the inflated rate you paid upfront.
-
Who it suits: Travellers who like hassle-free drop-offs but don’t plan on heavy mileage.
Free Tank (Special Offers)
-
How it works: A tank of fuel is bundled into the rental cost, most common in the USA.
-
Pros: No separate fuel charge, good if included with extras like GPS or additional drivers.
-
Cons: Not truly “free” – the cost is built into the package.
-
Who it suits: Holidaymakers in the US taking advantage of package deals.
Fuel Deposits – What to Know in 2025
Many suppliers now block a fuel deposit (typically £80–£200 / €100–€250) on your credit card. If you fail to return the car full under a full-to-full policy, the surcharge is taken from this deposit. Always check the rental agreement for details.
Rhino Car Hire Recommendation
For most customers, Full to Full remains the best choice. You only pay local fuel prices, you’re in control, and there are no hidden mark-ups. Just remember to fill up before you return the car.
If convenience is your priority, a Full to Empty policy may suit you better – but be prepared to pay more for it.
