Running out of fuel can be dangerous and inconvenient, and it may damage your car. While some cars may have a small buffer after hitting 0 miles, this is not guaranteed and should be treated as a final warning. The exact number of miles you'll be able to drive when the fuel light comes on depends on your car's make and model, as well as your driving style and road conditions. Data suggests cars can travel between 30 to 45 miles after the fuel warning light appears, but this can vary. Electric vehicles (EVs) are different, and when the battery reaches 0%, the car will typically enter Turtle mode, allowing you to get to the side of the road or down the block safely.

The fuel light comes on at 5 litres remaining
Driving with the fuel light on is not advisable. It can be dangerous for you and other people on the road. In some places, such as Germany, running out of fuel on a motorway is illegal and can result in a fine. In the UK, while not illegal, if your car causes an obstruction, you could face fines or penalty points.
It is not worth taking any chances, and it is much more sensible to fill your tank as soon as the fuel light comes on. Running out of fuel can damage your car's fuel pump and injectors, potentially leading to costly repairs. Additionally, getting stranded on the road can be dangerous.
Some cars may have a small buffer after hitting "0 miles" on the dashboard, giving you an extra 10-15 miles. However, this is not guaranteed, and it is best to treat "0 miles" as a final warning. Relying on this buffer could result in an expensive breakdown call-out.

Running out of fuel can damage your car's fuel pump
Running out of fuel is not ideal for several reasons. Firstly, it can be dangerous to you and other road users. Losing power suddenly on a busy road or motorway can be hazardous, especially if you're unable to pull over safely. In some places, like Germany, running out of fuel on a motorway is seen as a preventable breakdown and could result in a fine.
Secondly, it can be harmful to your car's fuel pump and injectors, potentially leading to costly repairs. When a car is low on fuel, it will draw in air along with the last dregs of fuel. This air could stop the engine from starting again, as it disrupts the fuel-air mix needed for combustion. The engine will also draw in debris and particles that have built up at the bottom of the fuel tank, which can cause blockages in the filters. This will prevent the engine from performing at its best or even cause it to not start at all.
Diesel vehicles are particularly susceptible to damage from running out of fuel. The powerful fuel injectors in diesel engines start pulling in lots of air once there's no more fuel in the tank, which can have a catastrophic effect on different components within the system. When the fuel system becomes completely clogged with air, it damages the injectors and filters, and can make it incredibly difficult to get the engine turning over again.
To avoid these issues, it's recommended to fill your tank as soon as the fuel light comes on.

Some cars have a buffer after hitting 0 miles, giving an extra 10-15 miles
Running out of fuel is not ideal for any driver. It can cause damage to the car's fuel pump and injectors, potentially leading to costly repairs. Additionally, getting stranded on the side of the road is not only inconvenient but can also be dangerous for you and other road users.
While it is not recommended to drive anywhere other than to get fuel when the light comes on, some cars may have a small buffer after hitting "0 miles" on the dashboard. This buffer might give you an extra 10-15 miles, but it is not guaranteed and should not be relied upon. Treat "0 miles" as a final warning, and fill your tank as soon as possible.
The exact number of miles you can drive after the fuel light comes on will depend on several factors, including the type of car, your driving style, road conditions, weather, traffic, and the fuel efficiency of the vehicle. For example, data suggests that a Ford Fiesta can travel around 37 miles after the fuel light comes on, while a Volkswagen Golf can manage approximately 44 miles.
It is worth noting that driving with a fuel light on can be dangerous and, in some cases, illegal. For instance, in Germany, running out of fuel on a motorway is considered a preventable breakdown and could result in a fine. While it may be tempting to push your tank to the limit, it is much more sensible to fill up as soon as the fuel light appears.

Factors like driving style and road conditions affect how long you can drive after the fuel light comes on
When the fuel light comes on, it's best to fill up as soon as possible. While you may still have some fuel left in the tank, the amount varies depending on factors such as driving style and road conditions. Aggressive driving, for example, can cause a vehicle to consume fuel at a higher rate, resulting in the fuel light turning on sooner. Additionally, driving in traffic or on hilly terrain can reduce fuel efficiency, decreasing the number of miles you can drive after the light comes on.
Cold weather is another factor that can impact your vehicle's fuel economy. In extremely cold conditions, it is advisable to get to a gas station as soon as the fuel light illuminates. Furthermore, the weight of your vehicle and the type of fuel used can also affect your vehicle's range when the fuel light is on. Heavier loads or towing can reduce the distance you can travel, and different types of fuel have varying energy contents, which can influence your vehicle's performance.
The make and model of your car also play a role in determining how far you can go after the fuel light comes on. Different vehicles have different reserve sections, which are not actual reserve tanks but portions of the main tank. These reserve sections typically account for around 10% to 15% of the tank's total capacity. However, it's important to note that fuel sloshing around in the tank, such as when driving on a sloped road or going around corners, can cause the fuel sender to indicate less fuel than is actually available.
While it may be tempting to push the limits and see how far you can go after the fuel light comes on, it's important to remember that running out of fuel can have serious consequences. It can cause damage to your vehicle's fuel pump and injectors, leading to costly repairs. Additionally, it can result in dangerous situations for you and other road users. In some places, such as Germany, running out of fuel on a motorway is considered a preventable breakdown and may result in a fine. Therefore, it is always advisable to fill up as soon as possible after the fuel light illuminates to avoid any potential issues or inconveniences.

Driving with the fuel light on can be dangerous
Additionally, driving with a low fuel level can damage your vehicle's fuel pump, fuel filter, and injectors. Over time, small particles of dirt, debris, and corrosion can form in the fuel tank and be drawn into the engine and fuel lines when the fuel level is low. This can lead to blockages and clogging of vital vehicle components, resulting in reduced engine performance and potential engine misfires. In some cases, a bad misfire can damage your engine or even cause an accident. The risk of engine misfires is higher in poorly maintained vehicles, which may have lower fuel efficiency and a reduced reserve fuel buffer.
Furthermore, running out of fuel can be illegal in some places. For example, in the UK, while it is not illegal to run out of fuel, causing an obstruction on a motorway due to running out of fuel can result in fines and penalty points. Similarly, in Germany, running out of fuel on a motorway is considered a preventable breakdown and may result in a fine. Aside from the potential legal consequences, running out of fuel can also lead to costly repairs and the inconvenience of being stranded on the roadside.
While it may be tempting to push the limits and see how far you can go after the fuel light comes on, it is generally not worth the risk. The best course of action is to fill up as soon as possible after the fuel light illuminates. If you are critically low on fuel and searching for a gas station, it is recommended to turn off any unnecessary electronics, such as air conditioning, heated seats, or the radio, to reduce the strain on your vehicle's battery and extend the time before the engine dies. If you are in a remote area and unsure if you can make it to a gas station, it is advisable to pull over and call for a tow to avoid the risk of being stranded.
