How Much Fuel Does One Tank Gauge Segment Represent?

According to different car brands and models, the amount of fuel represented by one segment on the fuel gauge can vary. The specific details should be checked in the vehicle's user manual. Fuel gauges in cars currently on the market are divided into mechanical pointer-type and electronic-type. When refueling, it is advisable not to wait until the car is completely out of fuel and the warning light comes on, as this can easily cause engine damage and reduce its service life. Additionally, it is not recommended to fill the tank completely, as this increases the vehicle's weight, leading to higher fuel consumption. If the tank is overfilled, aggressive driving can cause the fuel to spill out due to vigorous movement, creating a safety hazard.
The question of how much fuel each gauge segment represents is quite interesting, as it entirely depends on your vehicle model. My car is a mid-sized sedan with a total fuel tank capacity of 50 liters, divided into four segments, averaging about 12.5 liters per segment. However, the actual situation isn't a simple division – the sensor design makes the fuel gauge display uneven. The first segment shows more fuel, allowing over 100 km of driving, but the last segment may have less than 5 liters, barely enough for a few dozen kilometers. Having driven different models, like a compact SUV with a 40-liter tank and five segments (averaging 8 liters per segment), I've noticed the last segment drops extremely fast, triggering the low-fuel warning within kilometers. As an experienced driver, I recommend not obsessing over segment counts; it's better to develop the habit of refueling when the gauge drops to half, protecting both the fuel pump and your safety. You can also make a simple estimate: note the mileage after a full tank, then divide the refuel amount by the kilometers driven after consuming one segment to understand your car's actual fuel consumption.
From my years of driving experience, there's no standard amount for each fuel gauge segment—it varies by vehicle. For example, my old car had a 60-liter tank with a four-segment gauge; the first segment contained about 15 liters, while the last segment had only around 5 liters. After switching to a compact car, the 40-liter tank now shows five segments, averaging about 8 liters per segment. However, the fuel gauge doesn’t deplete evenly, especially when only one segment remains—it burns through quickly, and before you know it, the warning light comes on. Once, I underestimated it, thinking I still had plenty left with one segment, only to nearly run out of fuel on the highway. So, I suggest not relying solely on counting segments; it's better to refuel when the gauge is in the mid-range to avoid emergencies. Remember, the vehicle manual specifies the exact capacity and display method—check it to avoid misjudgments.
