A full-to-full fuel policy means you receive the rental car with a full tank of fuel and return it with a full tank. You pay only for the fuel you actually use during your rental by refuelling the vehicle yourself before returning it.
Blanca Cars currently operates a full-to-full fuel policy.
This means:
- The rental car is supplied with a full tank.
- You use whatever fuel you need during your rental.
- Fuel is not included in the rental price.
- Before returning the car, you refill the tank to full.
- You return the vehicle with a full tank.
The current Blanca Cars FAQ states that if the car is not returned with a full tank, a €25 service charge applies in addition to the cost of the fuel needed to refill the vehicle.
The European Consumer Centre in Spain also identifies full-to-full as one of the standard rental-car fuel arrangements and recommends it where available because the customer can refill externally before returning the vehicle rather than paying for a pre-purchased tank.

Quick Answer: What Does Full-to-Full Mean?
The rule is simple:
At collection
Fuel tank: Full
During the rental
You pay for the fuel you use.
Before returning the vehicle
Refill the tank.
At return
Fuel tank: Full
For Blanca Cars:
Fuel included in rental price: No
Car supplied with full tank: Yes
Car should be returned full: Yes
Customer chooses where to refuel: Yes
Charge if returned below full: Yes
Current Blanca Cars service charge: €25
Fuel required to refill tank also charged: Yes
The easiest rule to remember is:
Receive it full. Use the fuel you need. Fill it again before returning it.
Why Is It Called Full-to-Full?
The name describes the fuel level at the two important points in the rental.
Start of rental
Full tank.
End of rental
Full tank.
The amount of fuel used between those two points is the customer’s responsibility.
For example:
You collect the vehicle with:
50 litres
During your holiday you use:
30 litres
Before returning the vehicle, you buy enough fuel to restore the tank to full.
The rental company does not charge you separately for those 30 litres because you have already replaced them yourself.
Is Fuel Included in the Rental Price?
No.
Blanca Cars’ current FAQ specifically lists fuel among the items not included in the rental price.
The rental price pays for use of the rental vehicle and the services included under the rental agreement.
The petrol or diesel you use while driving is your own travel expense.
This is similar to paying for:
- Tolls
- Parking
- Other journey-related expenses
The amount you spend on fuel will depend on:
- Distance driven
- Vehicle
- Driving conditions
- Fuel price
- Driving style
Do I Pay Blanca Cars for a Full Tank When I Collect the Car?
Under a normal full-to-full arrangement, the important principle is that you receive the tank full and return it full.
You are not buying an entire tank of fuel from the rental company simply because the vehicle is handed over full.
Instead, you replace the fuel you personally use.
This is one of the main differences between:
Full-to-full
and:
Pre-purchase fuel policies
How Is Full-to-Full Different From Pre-Purchase Fuel?
Rental companies can use different fuel arrangements.
The European Consumer Centre in Spain identifies several common models:
- Receive full and return full
- Pay for a full tank and return as empty as possible
- Pay the rental company for the fuel used
Blanca Cars uses the straightforward:
Full-to-full model.
What Is a Full-to-Empty Fuel Policy?
A full-to-empty or pre-purchase policy normally means the customer pays the rental company for a tank of fuel and is encouraged to return the car with as little fuel as possible.
This can create a practical problem:
You rarely know exactly how much fuel you will use.
If you return the vehicle with fuel still in the tank, you may effectively have paid for fuel you never used.
Why Do Many Customers Prefer Full-to-Full?
Full-to-full is straightforward because you control where you refuel and how much fuel you buy.
The European Consumer Centre in Spain has specifically recommended the full/full option where rental companies offer a choice, noting that customers can fill the vehicle at an external petrol station before return.
The main advantages are:
- Easy to understand
- No need to predict total fuel use
- Customer chooses the petrol station
- Customer sees the pump price
- No need to return the tank almost empty
- You pay for approximately the fuel you actually used
How Does the Blanca Cars Full-to-Full Policy Work?
The current Blanca Cars policy is:
1. Receive the Car Full
The vehicle is delivered with a full tank.
2. Drive Normally
Use whatever fuel you need during the rental.
3. Refuel When Necessary
You can fill the car during your rental whenever required.
4. Refill Before Return
Near the end of your rental, fill the tank again.
5. Return the Car Full
The vehicle should be returned with a full tank.
The current Blanca Cars FAQ confirms this arrangement directly.
What Happens if I Return the Car Without a Full Tank?
If a Blanca Cars vehicle is returned without the required full tank, the current FAQ states that:
A €25 service charge applies, plus the additional cost of filling the tank.
Therefore, returning the car below full can cost more than simply stopping at a petrol station before return.
For example:
Vehicle returned full
Extra refuelling charge:
€0
Vehicle returned below full
Potential cost:
Fuel needed to refill
- €25 service charge
The simplest way to avoid this is to refuel before returning the car.
Is the €25 Charge the Cost of the Missing Fuel?
No.
The €25 is the current service charge.
The fuel needed to restore the tank to full is additional.
For example:
Missing fuel:
€18
Service charge:
€25
Potential total:
€43
The exact fuel cost depends on how much fuel is missing and the applicable fuel cost.
What if the Tank Is Only Slightly Below Full?
The safest approach is still to return it full.
A full-to-full policy does not mean:
“Almost full is close enough.”
If the vehicle is supposed to be returned full, refill it properly before return.
This avoids disagreements over whether the fuel level satisfies the rental conditions.
How Close to the Return Location Should I Refuel?
Refuel reasonably close to your return location so that the vehicle remains effectively full when returned.
For example, if you fill the tank and then drive another:
150 kilometres
the vehicle will obviously no longer arrive with a full tank.
A better approach is:
- Plan your return route.
- Find a convenient petrol station near the return area.
- Fill the tank.
- Continue to the agreed return point.
Do I Have to Use a Particular Petrol Station?
Normally, the full-to-full principle is about the fuel level, not requiring you to use one specific filling station.
You can normally choose a convenient petrol station.
This gives you the ability to consider:
- Location
- Fuel price
- Opening hours
- Route
If your rental agreement contains a specific instruction, follow that instruction.
Should I Keep the Final Fuel Receipt?
It is a good idea.
A fuel receipt can provide a useful record showing:
- Date
- Time
- Location
- Amount of fuel purchased
This can be particularly useful if you refuel shortly before returning the vehicle.
It is also sensible to take a quick photo of:
- Fuel gauge
- Mileage
when returning the car.
These simple records can help if there is ever a question about the fuel level.
Do I Need to Photograph the Fuel Gauge?
It is not difficult to do and can provide a useful record.
Before handing the vehicle back, you can take a photograph showing:
- Fuel gauge on full
- Dashboard
- Mileage
The European Consumer Centre advises rental customers to take photographs when returning a rental vehicle, particularly as part of documenting the vehicle’s condition.
Should I Check the Fuel Level When I Receive the Car?
Yes.
When collecting or receiving the vehicle, check:
- Fuel gauge
- Fuel type
- Vehicle condition
If the rental agreement says the car is being supplied full, the gauge should correspond with that arrangement.
If something appears incorrect, contact Blanca Cars before beginning your journey.
What if the Tank Does Not Appear Full at Collection?
Tell Blanca Cars immediately.
Do not wait until the end of the rental to raise the issue.
The correct return level should match the fuel arrangement recorded for the rental.
If the vehicle is unexpectedly supplied at a different level, make sure the situation is clarified and recorded.
Is “Full” Always Exactly the Same Position on the Gauge?
Fuel gauges are not precision measuring instruments.
What matters for the customer is to genuinely refuel the tank according to the rental conditions.
The easiest approach is to fill the vehicle normally at a petrol station shortly before return rather than attempting to estimate the necessary amount from the gauge alone.
Should I Stop Refuelling When the Pump Stops Automatically?
Use the petrol station equipment normally and safely.
You do not need to try to force extra fuel into the tank after normal filling is complete merely to push the gauge beyond its normal full position.
The goal is to return the vehicle properly refuelled, not to overfill the fuel system.
What Fuel Does My Rental Car Use?
This is extremely important.
Rental vehicles may use:
- Petrol
- Diesel
- Electricity
- Another powertrain
Never guess.
The European Consumer Centre specifically recommends checking which fuel the rental vehicle requires because incorrect fuelling can cause serious engine damage for which the driver may be responsible.
Before refuelling, check:
- Fuel-cap information
- Vehicle instructions
- Rental documents
If you are unsure, contact Blanca Cars.
How Do I Know Whether the Car Uses Petrol or Diesel?
Look for the information provided with the vehicle.
Common places include:
- Fuel filler flap
- Fuel cap
- Dashboard
- Vehicle documentation
If there is any doubt:
Do not guess.
Contact Blanca Cars before putting fuel into the vehicle.
A short phone call is far better than filling the tank with the wrong fuel.
What Happens if I Put the Wrong Fuel in the Rental Car?
Stop using the vehicle and contact Blanca Cars immediately.
The current Blanca Cars FAQ tells customers who put the wrong fuel in the vehicle to stop using the car and contact the emergency service at:
The FAQ currently states that a €300 fee applies to incorrect fuelling.
Most importantly:
Do not continue driving.
If you notice the mistake before starting the engine, do not start it.
Is Wrong Fuel Covered by the Full-to-Full Policy?
No.
Full-to-full tells you:
How much fuel to return.
It does not mean:
Any fuel can be used.
Using the wrong fuel is a separate customer-responsibility issue.
Does Full-to-Full Mean Unlimited Fuel?
No.
A full-to-full policy does not include free fuel.
You pay for all the fuel you consume during your journey.
For example:
You drive:
1,500 kilometres
You may need to refuel several times during the rental.
The full-to-full rule only determines the fuel level at:
- Collection
- Return
What if I Use More Than One Tank During My Rental?
That is completely normal.
For example:
Start:
Full tank
After several days:
Nearly empty
You refill:
Full
Later:
Half tank
You refill again before return:
Full
There is no limit to how often you can buy fuel.
The important point is that the vehicle is returned full.
Example: Short Rental
You receive the car:
Full
You drive:
120 kilometres
Before return, you stop at a petrol station.
The car takes:
8 litres
You return it:
Full
Result:
No fuel-policy charge.
Example: Two-Week Holiday
You receive the car with a full tank.
During 14 days you drive around:
- Jávea
- Dénia
- Moraira
- Calpe
- Alicante
You refuel several times.
On the final day:
- Fill the tank near the return location.
- Keep the receipt.
- Return the car full.
The number of times you refuel during the holiday does not matter.
Example: Returned Half Full
The car was supplied:
Full
You return it:
Half full
Blanca Cars needs to restore the vehicle to the required fuel level.
Under the current published FAQ:
- Fuel needed to refill the tank is charged.
- €25 service charge applies.
Example: Returned Just Below Full
You refill the vehicle earlier in the day.
You then drive a significant distance before returning it.
The gauge is below full when you arrive.
Because the rental policy requires a full tank, the safest approach would have been to refuel again closer to the return location.
Example: Airport Return
You are returning a Blanca Cars vehicle for an Alicante Airport booking.
Before heading to the agreed return point:
- Find a petrol station on or near your return route.
- Fill the tank completely.
- Keep the receipt.
- Drive to the agreed return location.
Do not arrive at the airport with an almost-empty tank and assume the rental company will refill it at the same cost as a nearby petrol station.
Does Alicante Airport Have a Different Fuel Policy?
The location of the return does not automatically change the fuel policy.
A full-to-full rental should still be returned according to the fuel conditions in the rental agreement.
The same principle applies whether the vehicle is returned:
- At Alicante Airport
- At Valencia Airport
- In Jávea
- At accommodation
- At another agreed Blanca Cars location
Does Valencia Airport Have a Different Fuel Policy?
No separate general fuel principle applies simply because the car is associated with Valencia Airport.
If the rental agreement says:
Full-to-full
return it full.
Does Local Home Delivery Change the Fuel Policy?
No.
The vehicle can be delivered to:
- Home
- Villa
- Apartment
- Hotel
- Garage
- Other agreed location
and still operate under the same full-to-full fuel arrangement.
Collection method and fuel policy are separate issues.
Does Paying Cash Change the Fuel Policy?
No.
Blanca Cars’ current cash-payment guide confirms that the permitted method of payment does not change the full-to-full fuel policy.
Whether you pay by:
- Cash
- Debit card
- Credit card
the agreed fuel conditions still apply.
Does Using a Debit Card Change the Fuel Policy?
No.
Your payment method is separate from the fuel arrangement.
A customer using a debit card still needs to return a full-to-full vehicle with the appropriate fuel level.
Does Extending the Rental Change the Fuel Policy?
Normally, no.
Blanca Cars’ current rental-extension guide states that extending the rental period does not automatically change the agreed fuel arrangement.
For example:
Original rental:
7 days
Extended rental:
14 days
Fuel policy:
Still full-to-full unless Blanca Cars agrees otherwise.
What if I Return the Car Early?
Returning the vehicle early does not mean you can return it with less fuel.
The fuel arrangement is separate from the rental duration.
If your rental agreement requires:
Full-to-full
the vehicle should still be returned full.
What if I Have Very Little Time Before My Flight?
Plan your refuelling into your return journey.
Do not leave refuelling until the last possible moment.
A simple return plan might be:
90 minutes before agreed return
Travel toward the airport or return area.
Near the return location
Stop for fuel.
After filling
Continue directly to return.
This reduces the risk of arriving below full because of poor planning.
What if the Petrol Station Is Closed?
This is another reason to plan ahead.
Check:
- Station location
- Opening hours
- Whether pumps are automated
- Your return time
before the final journey.
Do not assume every small petrol station operates 24 hours.
How Do Petrol Stations Work in Spain?
Spain has both:
- Staffed petrol stations
- Self-service or automated pumps
Payment procedures can differ by station.
You may:
- Pay at the pump
- Pay inside
- Pre-authorise an amount
- Fill first and pay afterwards
depending on the petrol station.
The important thing for your rental is to choose the correct fuel and return the tank according to the agreed level.
Should I Refuel the Night Before an Early-Morning Return?
That can be practical if you will drive only a short distance afterwards.
For example:
Hotel:
5 kilometres from return point
You fill the car the night before.
In the morning you drive:
5 kilometres
The car will normally still be effectively full.
By contrast, if you fill the night before and then drive:
100 kilometres
you may need to refill again.
What if I Accidentally Put Too Little Fuel In?
If you notice before returning the car:
Go back to a petrol station and refill it properly.
This is usually simpler and cheaper than returning the vehicle below the required level and having a refuelling charge applied.
Does Blanca Cars Refund Fuel if I Return the Car With More Than a Full Tank?
A fuel tank cannot meaningfully be returned with more usable fuel than its designed full capacity.
Under a full-to-full model, the aim is simply to restore the vehicle to the full level at which it was supplied.
There is no reason to intentionally overfill the tank.
Do I Get a Refund if I Return the Car With Extra Fuel?
Under full-to-full, there is normally no separate refund for fuel you voluntarily leave in the tank.
For example:
You refill the vehicle and return it full.
That is simply compliance with the agreed policy.
This is another advantage of full-to-full compared with pre-purchase policies: you can plan your final refill based on what you actually used.
Is Full-to-Full the Same as Same-to-Same?
Not exactly.
Full-to-full
Vehicle supplied full and returned full.
Same-to-same
Vehicle supplied at another recorded level and returned at approximately that same level.
Blanca Cars’ standard public policy is:
Full-to-full.
Always follow the arrangement stated in your actual rental agreement.
What if My Rental Agreement Says Something Different?
The rental agreement applying to your individual vehicle should be followed.
The current Blanca Cars FAQ states that customers should follow the fuel arrangement specified in their rental agreement.
If the agreement and the vehicle’s actual fuel level appear inconsistent, contact Blanca Cars immediately so the position can be clarified.
Should the Fuel Level Be Recorded at Collection?
It is good practice to check it.
At collection:
- Look at the fuel gauge.
- Confirm the fuel type.
- Check the rental agreement.
- Raise any discrepancy immediately.
The same principle applies to documenting:
- Bodywork
- Wheels
- Interior
- Existing damage
Can I Ask Blanca Cars to Refill the Car Instead?
You can return the vehicle below the required level, but under the current published policy you may then incur:
- Fuel cost
- €25 service charge
For most customers, refuelling before return is therefore the simpler option.
Why Is There a Refuelling Service Charge?
If the vehicle is returned below the agreed fuel level, Blanca Cars has to:
- Take the vehicle for refuelling
- Spend staff time doing so
- Restore it for the next rental
The service charge reflects the additional work involved.
This is separate from the fuel itself.
Is the €25 Service Charge Included in the Rental Price?
No, because it only applies if the car is returned below the required fuel level.
A customer who returns the car full does not incur that refuelling service charge.
The easiest way to avoid it is:
Return the vehicle full.
Is Full-to-Full Part of the Insurance?
No.
Fuel policy and insurance are different parts of the rental agreement.
Insurance addresses matters such as:
- Damage
- Liability
- Theft
- Applicable excesses and exclusions
Fuel policy determines:
- Starting fuel level
- Required return fuel level
- Refuelling responsibilities
One does not replace the other.
Is Running Out of Fuel Covered by the Fuel Policy?
No.
Full-to-full does not mean fuel is supplied whenever you run out.
The driver is responsible for monitoring the fuel level during the rental.
Blanca Cars’ current guidance says customers are responsible for the fuel they use and should not wait until the vehicle’s estimated remaining range reaches zero before refuelling.
What Should I Do if I Run Out of Fuel?
Get yourself and the vehicle into the safest possible situation and contact Blanca Cars for instructions.
Do not automatically arrange:
- Tow truck
- Mechanic
- Other assistance
without first contacting Blanca Cars.
The appropriate solution depends on the location and circumstances.
Does Roadside Assistance Mean Fuel Is Free?
No.
Roadside assistance and fuel are separate issues.
Blanca Cars includes roadside assistance under the applicable rental conditions, but the customer remains responsible for normal fuel consumption.
Common Full-to-Full Fuel Mistakes
Forgetting to Refuel Before Return
Plan your final petrol-station stop.
Refuelling Too Far From the Return Point
A long drive afterwards can leave the tank below full.
Assuming Fuel Is Included
It isn’t.
Returning the Tank Nearly Full
The policy is full-to-full.
Assuming the €25 Charge Includes the Fuel
It doesn’t. Fuel cost is additional.
Throwing Away the Final Receipt
Keeping it is useful.
Guessing the Fuel Type
Check before refuelling.
Putting Petrol in a Diesel Car
Stop and contact Blanca Cars immediately.
Putting Diesel in a Petrol Car
Again, stop and contact Blanca Cars.
Driving After Realising the Wrong Fuel Was Added
Do not continue driving.
Assuming Paying Cash Changes the Fuel Policy
It doesn’t.
Assuming an Early Return Changes the Fuel Policy
It doesn’t.
Assuming the Airport Has a Different Fuel Policy
The agreed rental fuel policy still applies.

If you remember only one thing from this guide, remember this:
Full-to-full means Blanca Cars gives you the rental car with a full tank and you return it with a full tank. Fuel used during your rental is your responsibility. If the vehicle is returned below full, the current Blanca Cars policy applies a €25 service charge plus the cost of the fuel required to refill it.

Blanca Cars Full-to-Full Fuel Policy
The clearest Blanca Cars policy wording is:
Blanca Cars operates a full-to-full fuel policy. The rental vehicle is supplied with a full tank and should be returned with a full tank. Fuel used during the rental is not included in the rental price. If the vehicle is returned below full, a €25 refuelling service charge applies in addition to the cost of the fuel required to restore the tank to full.
This policy gives customers a straightforward way to manage their own fuel costs.
To avoid additional fuel charges:
- Check the fuel type when you receive the car.
- Monitor the fuel level during your rental.
- Refuel shortly before returning the vehicle.
- Fill the tank completely.
- Keep your final fuel receipt.
- Consider photographing the fuel gauge at return.
The current Blanca Cars FAQ confirms the full-to-full arrangement and the €25 service charge for a vehicle returned below full.

The European Consumer Centre identifies full-to-full as one of the standard rental fuel arrangements and recommends understanding the fuel policy before accepting the rental. Its consumer guidance has also recommended the full/full option where available.
Blanca Cars’ current FAQ states that its vehicle is delivered with a full tank and should be returned full, with a €25 service charge plus refuelling costs where the car is returned below full.
About This Guide
This guide explains how a full-to-full rental-car fuel policy works and separately identifies the current fuel arrangement published by Blanca Cars.
The principle is straightforward:
Full when you receive it. Full when you return it.
The customer pays for the fuel actually used during the rental by purchasing replacement fuel before return.
For Blanca Cars customers, the confirmed rental agreement should always remain the final source for the fuel arrangement applying to the individual vehicle.
