How Many Kilometers Can a Jetta Drive When the Dashboard Shows No Fuel?
1 Answers
When the Jetta dashboard indicates no fuel, it can still drive approximately 50-70KM, depending on driving conditions and habits. Once the fuel light comes on, you should promptly locate a gas station to refuel as soon as possible to avoid being stranded. Impact of Driving Conditions and Habits on Mileage: For most vehicles, the most fuel-efficient speed is 90Km/H, which is also the economic speed for many cars. Maintaining this speed can significantly extend the driving range. In urban areas, frequent stops and starts, low-speed operation, and constant braking increase fuel consumption, thereby greatly reducing the driving range. Other factors such as uphill driving, poor road conditions, heavy loads, and air conditioning use can also affect mileage. Hazards of Prolonged Driving After the Fuel Light Comes On: Driving for an extended period after the fuel light comes on can cause damage to the fuel pump and shorten its lifespan. The fuel pump consists of three main parts: the fuel level sensor (float), the pump core, and the fuel pressure control valve (relief valve). The pump core is essentially a small electric centrifugal pump that operates continuously from the moment the car is turned on until it is turned off. It dissipates heat in two ways: first, by the fuel it draws in during operation, which carries away some heat, and second, by being submerged in the fuel in the tank, which helps with cooling. If the fuel level in the tank is too low, it can lead to poor heat dissipation.
