How is fuel cost calculated?
2 Answers
Fuel cost is calculated as follows: Based on the total distance traveled by the car, the total amount of fuel purchased, and the fuel price at the time, the cost per kilometer is determined by dividing the total fuel cost by the fuel price and then by the mileage. Below are the characteristics of gasoline: 1. Operability: The energy of the car's internal combustion engine is converted from thermal energy to mechanical energy through ignition to power the vehicle. 2. Anti-knock performance: Gasoline has the ability to resist knock combustion during driving. The anti-knock performance of gasoline is reflected by its octane rating—the higher the octane rating, the better the anti-knock performance. 3. Stability: Gasoline has very stable properties under natural conditions and does not cause corrosion to equipment such as cylinders during storage and transportation.
I usually commute by car, and my biggest concern is fuel expenses. Calculating fuel costs is actually quite simple: first, see how many kilometers a full tank can last. For example, my car can run 600 km on a full tank. Currently, 95-octane gasoline costs 8 yuan per liter, and my car consumes about 7 liters per 100 km. So, the cost per kilometer is 7×8÷100=0.56 yuan. However, actual driving conditions can vary a lot. For instance, fuel consumption can spike to 10 liters per 100 km in traffic jams, while it drops to 6 liters per 100 km on highway trips over the weekend. When keeping track of expenses, I use a fuel consumption app that automatically calculates costs by inputting fuel prices and mileage, which is much more accurate than manual calculations. Recently, fuel prices have been fluctuating a lot, so I always fill up on membership days to save a bit of money.
