What does it mean when my petrol light comes on?
Your fuel light is a warning that you are starting to run low on fuel and will need to top up soon.
The light is usually triggered when your fuel tank is down to about 10% capacity, so there is still fuel in there. This light is designed to turn on at this point to give drivers fair warning to find a fuel station before the tank is completely empty.
How many miles can I drive when my fuel light comes on?
There's no singular answer to this question as it varies from car to car. Your driving style and the type of driving you are doing will also have an impact on this.
Some cars may have a digital display that will show you an estimate of how many miles you have left. These figures aren't 100% accurate though and should only be used as an estimate.
To give you some peace of mind, we've picked some of our most popular cars to show you how far each might go (on average) when the fuel light has come on:
- Ford Fiesta - 37 miles

What should I do if I don't have enough fuel to get to a petrol station?
If you cannot make it to fuel station before running out of petrol, find a safe place to pull over and put your hazard lights on. You should contact someone to bring you a jerry can of fuel, or your breakdown company may be able to help you.
Running your vehicle right down to completely empty and breaking down at the side of the road could put you in a dangerous situation and could also cause damage to your vehicle.
What will happen if I drive on an empty tank?
Driving with really low fuel levels could not only leave you stranded, you could end up damaging your car in the process.
As fuel levels get lower, your car can pick up debris from the bottom of the tank which could damage the fuel filter and pump. It could also cause damage to your catalytic converter.
Allowing your fuel pump to run completely dry could also be a costly vehicle repair.
A lot of diesel cars are equipped with an engine management system that will shut the engine down before you run into trouble like this, but if you drive a petrol car, there's no such system in place for you.
