When you rent a car, understanding the fuel policy is crucial to avoid unexpected costs and ensure a smooth rental experience. Rental companies like Budget offer various fuel service options, and knowing what they entail can save you money and hassle. This guide will break down the common fuel service options, helping you make the best choice for your needs.

The Basics: A Full Tank of Fuel
Most rental agreements begin with the vehicle provided with a full tank of fuel. This is the most straightforward option, allowing you to drive off the lot with peace of mind, knowing you have a full supply. However, the expectation of a full tank isn't always guaranteed, and it's always wise to check the fuel gauge and the rental agreement to confirm the starting fuel level.
Fuel Service Options: What's Available?
Rental companies typically offer several ways to handle the fuel:
1. Return with the Same Fuel Level
This is the most common and often the most economical option. You receive the car with a full tank, and you are expected to return it with a full tank. If you don't, you'll be charged a fuel service charge. This charge is usually significantly higher than the price of fuel at a local petrol station. To avoid this, simply refuel the car yourself before returning it. It's advisable to refuel at a station close to the rental return location to account for any slight fuel consumption between the last fill-up and the return.
2. Fuel Purchase Option (Prepaid Fuel)
Many rental companies offer a fuel purchase option, often referred to as a prepaid fuel plan. With this option, you pay an upfront fee to have a full tank of fuel at the start of your rental. You can then return the car with any fuel level, without incurring additional fuel service charges. The cost of this option is typically higher than the cost of filling the tank yourself, but it offers convenience. You won't get a refund for any fuel remaining in the tank, so this option is usually best if you anticipate using most, if not all, of the fuel.
When is the Fuel Purchase Option a good idea?
- If you have a very short rental period and don't want to worry about finding a petrol station.
- If you're driving a long distance and are unsure of fuel availability along your route.
- If you have a tight schedule and want to avoid the hassle of refuelling before returning the car.
3. Refuelling Service Charge
If you choose not to accept a prepaid fuel option and return the vehicle with less fuel than you received it with, you will be subject to a refuelling service charge. This charge is calculated based on a per-gallon rate or a per-mile rate, as specified in your rental agreement. The per-gallon rate is applied if you purchase fuel during the rental but don't return the tank as full as it was at pick-up. The per-mile rate is used if you don't purchase fuel at all. These rates are almost always higher than the retail price of fuel.
Example of Refuelling Charges:
| Scenario | Action | Outcome |
|---|---|---|
| Returning with less fuel than provided | No refuelling | Charged a high per-gallon or per-mile refuelling fee. |
| Purchasing fuel but not returning a full tank | Provide fuel receipt if requested | Charged per gallon for the difference, at a rate higher than pump prices. |
| Accepting Fuel Purchase Option | Return with any fuel level | Pay upfront fee; no additional fuel charges. No credit for remaining fuel. |
| Returning with a full tank | Refuel yourself before return | Avoid all fuel service charges. |
4. Low Mileage Exception
Some rental agreements may have a provision for drivers who travel a very short distance. For example, if you drive fewer than 75 miles, Budget may add a flat fee to the rental. This fee can typically be avoided by providing a receipt for fuel purchased at the time of return, which reverses the flat fee.
Electric Vehicles (EVs) and Fuel Policies
Electric vehicles come with their own set of fuel-related considerations:
- Battery Charge Level: EVs must typically be returned with a battery charge level of at least 70%.
- Charging Fees: If an EV is returned with a battery charge level below 70% but above 10%, a charging fee will be assessed. If it's returned with less than 10% charge, an additional low-charge fee applies.
- Charging Costs: You are responsible for any costs associated with recharging the EV, which may include registration or account fees with charging providers.
- No Fuel Delivery for EVs: Unlike petrol or diesel cars, roadside assistance for EVs cannot deliver fuel or a charging station. If an EV runs out of battery, it will need to be towed to the rental location, and towing fees will apply.
- Towing EVs: You are not authorised to call a private tow for an EV; all tows must be arranged through roadside assistance and must be on a flatbed.
Tips for Managing Fuel Costs
- Check the Fuel Gauge at Pickup: Before leaving the rental lot, note the fuel level on your rental agreement and take a photo of the gauge. This protects you if there's a dispute about the starting fuel level.
- Plan Your Refuelling: If you opt to refuel yourself, use a map app to find petrol stations near your destination. Consider the time it takes to refuel to avoid being late for your return.
- Compare Options: Before you rent, compare the cost of the prepaid fuel option against the potential cost of refuelling yourself and paying a service charge if you return the car with less fuel. For longer rentals or higher mileage, refuelling yourself is usually cheaper.
- Understand EV Charging: If renting an EV, familiarise yourself with charging options and costs in the area you'll be travelling. Plan your charging stops as you would plan fuel stops for a conventional vehicle.
- Read the Agreement Carefully: Always read the fuel policy section of your rental agreement thoroughly. Pay attention to specific rates, fees, and any state-specific regulations that might apply.
Frequently Asked Questions
Q: Does Budget provide a full tank of fuel?
Most rentals start with a full tank, but it's essential to check your rental agreement and the fuel gauge upon pickup.

Q: What happens if I return the rental car with less fuel than I received it with?
If you haven't opted for a prepaid fuel plan, you will be charged a fuel service charge, which is typically higher than the retail price of fuel. You can avoid this by refuelling the car yourself before returning it.
Q: Is the prepaid fuel option worth it?
It depends on your usage. It offers convenience but may be more expensive if you don't use all the fuel. Calculate the cost versus the convenience for your specific rental.
Q: Can I use my own fuel card?
Generally, you cannot use your own fuel card to pay for fuel directly through the rental company's refuelling service. You would use it to refuel the car yourself at a petrol station.
Q: What if I rent an electric vehicle (EV)?
EVs require you to return them with a minimum battery charge (usually 70%). Failure to do so will result in charging fees. You are also responsible for the cost of charging.
By understanding these fuel service options, you can make an informed decision that best suits your travel plans and budget, ensuring a positive rental car experience.
