It would seem that the problem of calculating fuel consumption should not exist now, since modern cars are equipped with more and more advanced electronics. But, as practice shows, the readings of flow meters are often very approximate and do not give a complete picture of the real consumption of gasoline. In this case, you will have to do the calculations yourself.
Instructions
Step 1
We'll have to remember the old-fashioned ways, which, as it turned out, have not lost their relevance today. Refuel at the nearest gas station “under the traffic jam” and record the mileage of the car. Do the same for the next full refueling. If there were intermediate refueling between them, then save the receipts, as they indicate the amount of gasoline. Determine the mileage by calculating the difference in the speedometer readings, for example, it will be 350 km, and the amount of fuel consumed according to your receipts is 30 liters. Fuel consumption per 100 km is calculated using the following formula: (30 l: 350 km) x 100 km = 8.57 l. However, one should not think that this is an absolute constant indicator. Fuel consumption depends on many factors - driving style, traffic jam time, season, road and vehicle conditions.
Step 2
Do not forget about the errors that even the most modern refueling equipment at gas stations "suffers" from. Measurements have shown that the more fuel you pour into the tank, the more underfilling and, conversely, with small "portions" - everything is fair. So don't be surprised if your mileage with three 10-liter fillings is the same as with a single 40-liter fill.
Step 3
In the conditions of motor transport enterprises, fuel consumption rates are determined in accordance with the Order of the Ministry of Transport of the Russian Federation of 2008-14-03. In particular, it provides for an increase in fuel consumption when traveling in mountainous and high-mountain areas. So, at an altitude of over 3000 m, fuel consumption increases by an average of 20%. There are similar norms for cities with a certain number. If you live in a city with a population exceeding 3 million people, then you can safely add 25% to yourself, and in a city with a population of up to 250 thousand people this figure will be much less - only about 10%.
