Is the fuel consumption displayed on the car screen really accurate?
Many car users often refer to the fuel consumption of their vehicles from the data displayed on the information screen, but in reality, how accurate and reliable are those results?
In the context of constantly fluctuating fuel prices, one of the factors that customers and car owners are interested in when choosing to stick with a gasoline or diesel internal combustion engine vehicle is fuel consumption. Unlike older models, most cars today have fuel consumption parameters during vehicle operation displayed on the driver information screen. Therefore, when asked about the fuel consumption of a vehicle, many people often only pay attention to the parameters displayed on the screen.
However, many car owners wonder how reliable and accurate the fuel consumption displayed on the car screen is (!?) Because in reality, there are many factors that affect the accuracy of the fuel consumption displayed on the car screen. These factors include: Sensors that measure the amount of fuel used and the calculation systems used to process it; driving conditions and fuel quality.
Typically, each car model of each car brand uses different fuel sensors and calculation systems to process data on the car's fuel consumption. Therefore, car models with the same engine capacity and weight can have different fuel consumption levels.
Meanwhile, traffic conditions, driving habits, air conditioning use and other factors related to driving… all affect fuel consumption. All of these can also cause the fuel consumption information displayed on the car screen to be different from reality. Especially now, the quality of fuel poured into the car also plays an important role in changing the car's fuel consumption. The car's system may not take these factors into account.
Is the fuel consumption displayed on the car screen true to reality?
According to auto repair technicians, the fuel consumption displayed on a car's display screen often does not accurately reflect the car's actual fuel consumption. This is because the information displayed on the screen is usually information about the average fuel consumption over a period of driving.
There are also other factors such as temperature, humidity and air pressure that can also distort the actual fuel consumption of the vehicle compared to the parameters displayed on the screen. Because the sensor system, measuring fuel consumption on the vehicle may not take these factors into account.
The most accurate way to estimate your car's fuel consumption
According to some long-time car users, the most accurate way to calculate the fuel consumption of a car is to do it yourself. Specifically, to estimate the fuel consumption of the car, users can do it by filling the gas tank and recording the number of kilometers the car displays on the screen. Then drive, use the car every day. When it is time to refuel, continue to fill the gas tank as usual, record the number of kilometers displayed on the car during this refueling to calculate the number of kilometers the car has traveled. Then divide the number of kilometers used by the number of liters filled. This will be the consumption in km/liter.
In short, the fuel economy information displayed on your car's display is only an estimate, and may not always be close to reality. If you want to know your car's fuel economy, it's best to calculate it yourself. There are a number of apps that can help you calculate fuel economy (such as Fuelly), but they require a full tank of gas to get the most accurate results.
