Cars are more efficient when the tank is full, this is an expert explanation
Why does the car feel more efficient when the fuel is full tank?
Many car drivers feel that their vehicles feel more efficient when the fuel tank (BBM) is full. However, this is not always directly related to the efficiency of the engine or the ability of the car to consume fuel. There are several factors that can explain these feelings.
Minimal fuel evaporation
One of the main reasons why the car feels more efficient when the fuel is full tank is due to the reduction in the potential for fuel evaporation. A full tank has less air space than a tank that is only half or almost empty. This limits the amount of fuel vapor that can be released into the atmosphere.
Immun, owner of a Ford specialist workshop in Trucuk, Klaten, Central Java, explained that full fuel refueling is often associated with efforts to prevent evaporation. “The full tank has less air space, so the potential for evaporation can be smaller, so there is not much wasted air,” he said.
In modern cars, the fuel vapor control system has been implanted to minimize evaporation. Nevertheless, full tank refueling still provides additional benefits in terms of reducing evaporation risk.
Fuel pump performance
In addition, the performance of the fuel pump also has an effect. The fuel pump submerged in the fuel will work more stable because it gets enough cooling. If the tank is empty too often, the pump potentially heats up faster and is at risk of damage in the long term.
“This condition can affect the performance of the fuel supply. Fully filling can save time and reduce the potential for waste due to queuing or the engine is running when it stops,” said Imun.
vehicle weight and fuel consumption
Although full tank fuel can provide benefits in terms of efficiency and comfort, there are other sides that need to be considered. A full tank adds to the weight of the vehicle, so it could theoretically increase fuel consumption a bit.
However, the additional weight is relatively small compared to the total weight of the car. The impact on fuel consumption in daily use is generally not too pronounced.
Conclusion
Directly, full tank fuel does not make the car more efficient. However, there are indirect benefits that support the efficiency and convenience of vehicle use. Full fuel can help reduce the risk of fuel evaporation, maintain the performance of the fuel pump, and reduce the need to stop at gas stations too often.
By understanding these factors, drivers can make wiser decisions in refueling their cars.
