Gasoline consumption is the amount of fuel used by the car. This characteristic of the machine motor is currently one of the most important. And for decades, the world's leading engineers have been solving the problem of reducing gasoline consumption.
Gasoline consumption can be measured by calculating the amount of fuel that the car spends when passing a certain distance. Now in countries where the metric system of measures is used, consumption is measured in liters for every hundred kilometers. The lower the value, the more economical the car.
Gasoline consumption can be calculated in another way - they measure the distance during which the vehicle will completely consume a certain amount of fuel. This method is generally used in countries where the English dimensional system is used.
In South Korea, Japan and India, economy is measured in kilometers per liter. At the same time, the higher the value, the more economical the car.
For more accurate calculations, engineers have selected several special cycles:
1. The urban cycle, characterized by highthe intensity of movement, the need for overheating, the operation of the motor during a stop in traffic jams and at traffic lights, as well as a sharp reset and acceleration. As a result of such work, a large consumption of gasoline is observed.
2. Extra-urban cycle, characterized by a smoother ride and more stable speed. At the same time, a decrease in gasoline consumption is observed.
3. A mixed cycle is something in between.
The consumption of gasoline is affected by a large number of factors. The main reasons for the increase in consumption: malfunctions of the engine or its systems, vehicle acceleration, incomplete combustion of gasoline, “aggressive” driving style, increased driving resistance (car load, open windows, jammed brakes, transmission malfunctions).
Proper condition of the machine, the choice of the most optimal driving mode, driver experience is the key to optimal fuel use.
Fuel consumption is also affected by other less important factors: aerodynamics, curb weight, gear ratios.
Consumption rates
All transport companies set their maximum allowable fuel consumption levels when using vehicles. There are basic and settlement-normative levels of consumption. The base one is determined according to the standard scheme and sets the fuel consumption rate under normal conditions. The calculation and standard establishes certain operating conditions, as well as some other factors.
Gasoline mileage rates may increase if:
-work during the cold season in the northern and southern regions of the Russian Federation, as well as in the Far North;
- when working on roads with a complex plan;
- when driving in mountainous areas;
- when transporting dangerous or oversized cargo;
- during driving practice;
- when the air conditioner is running;
- when driving in the city (depending on how dense the traffic is);
- when working in difficult conditions (floods, snow, ice);
- when driving a new car or a car after a major overhaul.
Gas mileage is one of the most important characteristics of every car's engine. It is on its improvement that work is underway in many countries of the world.

Car stability and handling: criteria and factors
Car handling is a factor that worries many drivers. Not only the speed of movement, but also the safety of passengers depends on it. There are several levels of control - basic and "advanced". In this article you can find information on how to improve car handling and whether it is necessary to do this for ordinary city trips
How do they cheat at gas stations? Fuel injection schemes. What to do if cheated at a gas station
Cases of fraud at gas stations in Russia and CIS countries are not uncommon. Despite the rather high cost of fuel, the owners of large and small chains selling fuel are constantly implementing schemes to snatch additional money from car owners in the form of underfilling of fuel. Every day, cunning entrepreneurs come up with newer and more sophisticated ways to take money from the population
Why put alcohol in a gas tank? Alcohol in the gas tank to remove water condensate
Practically every more or less experienced driver has heard of the practice of using alcohol as a gas tank cleaner from water. Given that the winter cold will come very soon, it is simply necessary to remove excess liquid from the tank, because it can cause some problems (we will talk about them below). Someone thinks that you can pour alcohol into the gas tank, which will effectively remove water, but there are opposite opinions
How to save gas? How can you reduce your gas mileage
This article will discuss how to save gasoline on cars with different fuel injection systems. The cost of fuel is constantly growing, this does not please motorists. But it does not force you to switch to mopeds or bicycles. On the contrary, everyone is trying to find a way to reduce fuel consumption
Dips when you press the gas. Failure of the gas pedal
Failure of the gas pedal - a rather rare phenomenon for modern cars. However, if you notice that your iron friend began to twitch when you press the gas, do not put off solving this problem until later. In today's article, we will find out the causes of this phenomenon, as well as consider ways to solve this problem
