How many miles can you really go?

The fuel light on your dashboard comes on. Don't panic! You still have some wiggle room to find a gas station. But how many miles can you actually drive on reserve? Find out the answers to this crucial question and the pitfalls to avoid.

Variable autonomy depending on the vehicle

There is no universal answer to the question of reserve range. It depends on many factors specific to each vehicle:

The size of the tank

  • Fuel consumption
  • The type of driving
  • The route taken
  • Traffic conditions
  • Vehicle load
  • Despite these variables, some estimates can be made. As a general rule, the reserve is about one-eighth of the total tank capacity. So, when the light comes on, you can expect to travel an average of 45 kilometers.

    This distance varies depending on the size of the vehicle:

  • Large models offer a reserve range of up to 120 km
  • Small cars usually have a range of 45 to 50 km
  • Beware of the on-board computer

    Modern vehicles are equipped with an on-board computer that displays an estimate of the remaining kilometers when you enter reserve. Be careful, however, this information is not completely reliable.

    This figure is calculated from the average consumption over a given period. It does not take into account changes in traffic conditions or driving style. It is therefore best considered as a simple indication.

    To get a more precise idea, some websites like Tank on Empty allow drivers to share their experience of driving in reserve. Although this information should be taken with a grain of salt, it can provide useful guidance.

    Risks to your vehicle

    Frequently driving on reserve is not without consequences for your car. Two components are particularly vulnerable:

  • Fuel Pump: Air entering the system can cause bubbles and lead to failures
  • Injectors: They are exposed to impurities and dirt accumulated at the bottom of the tank
  • In the long term, these repeated requests can lead to significant repair costs.

    Beware of fines

    In addition to the mechanical risks, driving on reserve can also have financial consequences. If you run out of fuel on the road, you are exposed to several types of fines:

  • 80 euros if you do not wear the safety vest when installing the warning triangle
  • 200 euros for negligent driving, because running out of fuel compromises the operation of the power steering and brakes
  • Between 2,000 and 3,000 euros if you transport fuel in an unapproved container
  • Adopt the right reflexes

    To avoid these inconveniences, some good practices are essential:

  • Plan your journeys and locate service stations along your route
  • Do not let the fuel level drop too low, especially on long journeys
  • Adopt flexible driving to optimize your consumption
  • Keep an approved jerry can in your trunk in case of emergency
  • Driving on reserve should only be a last resort. By taking care of your vehicle and anticipating your fuel needs, you will avoid many hassles on the road. Remember that the best way to save fuel is still to adopt responsible and ecological driving.
