How is car fuel cost calculated?

First, fill up the fuel tank (until the pump nozzle clicks off), reset the trip meter to zero. After the second fill-up (also until the nozzle clicks off), divide the amount of fuel added the second time by the kilometers driven since the trip meter was reset to get the actual fuel consumption. Then multiply by the unit price of gasoline. Below is the calculation method for gasoline cost: 1. Fill up the fuel tank until the pump nozzle clicks off, and reset the trip meter to zero. Try to drive as many kilometers as possible, as too few will result in inaccurate calculations. The next time you refuel, fill up until the nozzle clicks off again. Then, divide the liters of fuel added by the kilometers shown on the trip meter, move the decimal point two places to the right, and this number will be the car's fuel consumption per 100 kilometers. 2. If the car is equipped with an onboard computer, even better, as the instant fuel consumption and average fuel consumption will be automatically displayed on the dashboard screen.
I usually calculate fuel costs by keeping track of two numbers: how many liters of fuel I added and how many kilometers I drove. For example, last time I added 40 liters of fuel and drove 500 kilometers, so the fuel consumption per 100 kilometers was 8 liters. Multiply this number by the latest fuel price, like the current price of 92-octane gasoline at 7.5 yuan per liter, and it costs about 0.6 yuan per kilometer. However, my old SUV has relatively high fuel consumption. If it were my colleague’s hybrid car, it would only consume 4 liters per 100 kilometers, saving half the money under the same road conditions. The size of the fuel tank also matters. My 60-liter tank costs 450 yuan to fill up, enough to drive over 700 kilometers, but in summer when the air conditioning is on, the mileage drops by 10%.
