Although many think that the tank is empty when the gauge reads E, this is not true. Learn its meaning and how to take care of your car’s engine and fuel system.
When your car’s fuel gauge reads letter Eit is common to think that the tank is empty and that it is time to fill up with gas. However, this interpretation is not entirely correct. Although the “AND“on the meter refers to the word”empty” (empty in English), does not necessarily mean that the tank is completely dry. Vehicles are designed with a fuel reserve even when the indicator reaches this level, which leaves a margin for the driver to look for a service station.
Although this fuel reserve can be useful in emergencies, it is not recommended to rely on it constantly, as frequent use implies risks that can affect both the vehicle performance like the engine health.

What the E on the fuel gauge really means and why it is important to understand it
The letter AND on the gas gauge, which is commonly associated with an empty tank, actually has a more functional purpose: leaving a small fuel reserve when the indicator reaches this point. The amount of gasoline available in this reserve varies depending on the car model, but usually represents between 5% and 15% of the total tank capacity, which could mean between 50 and 80 additional kilometers of autonomy.
This extra margin is useful for emergency situations in which you have to get to a service station immediately. However, driving with the tank AND constantly can have negative consequences for the vehicle engine.
The gasoline pumpresponsible for feeding the engine, uses fuel not only for its operation, but also as lubricant and refrigerant. When the fuel level is too low, the pump can run dry, which increases the risk of friction, overheating and costly damage.
