How Much Fuel Should You Fill at Once for Your Car?

[StMiguel]

According to the relevant mandatory national standards, the rated capacity of a car's fuel tank should be controlled at 95% of its maximum safe capacity. Below are the relevant details: 1. Example: Taking a 60-liter fuel tank as an example, it can be filled up to a maximum of 75 liters, but the stored fuel should not exceed 60 liters. 2. Rated Capacity: The accuracy of the refueling amount cannot be judged based on the rated capacity of the fuel tank. The fuel tank of a gasoline-powered car is a container, not a measuring tool, so it cannot be used as a basis for judging measurement accuracy. Moreover, according to relevant national mandatory requirements, the rated capacity of a car's fuel tank should be controlled at 95% of its maximum safe capacity. 3. Car Fuel Gauge: Many car fuel gauges operate via a float inside the tank that moves up and down, driving an electronic sensor. The sensor then transmits the generated electronic signal to the fuel gauge pointer, displaying it on the gauge. As a result, there can be significant errors.
