How Many Miles Can You Drive When The Fuel Light Comes On?

Most of us have probably driven with the fuel light on before, but few have an accurate idea of how many miles we can go before the engine cuts out. A good rule of thumb is that, in most cars, you have roughly 50 miles left when the light comes on.

With this in mind, let's compare the fuel reserves of different models. The estimated distances in this guide are based on an analysis conducted by CompareTheMarket.

Fuel reserve by model

Car	Distance
Toyota Prius	99 miles
Mercedes E-Class	85 miles
Land Rover Range Rover	73 miles
Honda CR-V	69 miles
Jaguar F-Pace	68 miles
Volvo V40	66 miles
Jaguar XE	63 miles
Volvo C30	62 miles
BMW 3 Series	59 miles
Audi A3	58 miles
Land Rover Discovery	58 miles
Citroen DS3	58 miles
Mitsubishi Outlander	56 miles
Renault Kadjar	56 miles
Volkswagen Golf	55 miles
Suzuki Alto	31 miles
Kia Picanto	31 miles

Which car model gives you the most miles after the low fuel light comes on?

As you can see from the table above, the model with the biggest fuel reserve is the mighty Toyota Prius. Since the Prius is a hybrid, you'll already get more miles from a tank, and the sizeable fuel reserve is the cherry on top.

Which car model gives you the least miles after the low fuel light comes on?

At the bottom of the list are the Suzuki Alto and the Kia Picanto, both with around 31 miles in the reserve tank.

What happens when a car runs out of petrol?

Running out of fuel is bad news - and not just because it could leave you stuck by the side of the road.

Especially in older cars, damage happens even before you drain the last drop of fuel. This is because the bottom of the tank might contain sediment that could block the fuel filter, stopping or reducing the fuel flow.

When the tank is empty, your fuel pump starts drawing in air, and without fuel to cool it, it may overheat. Although this won't cause serious damage if it happens once, running out of fuel multiple times could damage the pump.

The situation is worse for diesel cars because diesel is used as fuel and a lubricant - without it, the fuel pump and injectors can quickly become damaged. Another thing to consider is that, unlike in petrol cars, air is not supposed to mix with fuel at this stage - if it enters the system, you may have to bleed it, which is expensive and time-consuming.

For all these reasons, it's best to avoid running out of fuel if you can. When you see the low fuel light - or ideally before it comes on - find the nearest petrol station and fill up.

How far can you drive on 0 miles to empty?

The answer to this question will vary depending on several factors, such as your driving style, weather conditions, and the make and model of your car.

Most modern cars don’t have a separate reserve tank, but they will probably give you a few more miles after the dial hits zero. YouTuber AutoVlog put his 4V Ford Fusion to the test in 2017, managing 21.6 miles after the fuel gauge first reached zero. You can watch the video here.

That said, driving with extremely low fuel can damage your engine, so it’s best to fill up as soon as possible.
