Anyone who buys a car asks himself a question about fuel consumption. Gasoline prices are constantly rising, and it is not known how much it will cost to refuel a car tomorrow. How to make a calculation if there is no on-board computer? In practice, this issue is solved quite simply, and we will now consider this.
First, we record the speedometer data at the time of fixing the mileage. Next, at the gas station, we fill in a full tank of fuel, namely full, pour it to capacity (this is extremely important for calculating fuel consumption). After that, we just go about our business in the usual traffic conditions. For a correct calculation, it is required to run over 400 km. At this distance, you can make the correct calculation of fuel consumption.
After that, you should go to the gas station and fill in a full tank of gasoline again, while again writing down the amount of gasoline entered into the tank. Now it is possible to calculate fuel consumption.
Look at the record how many kilometers traveled, divide these kilometers by the amount of gasoline filled in the second time and get fuel consumption per hundred kilometers.
Calculating fuel consumption can also show high fuel consumption. Some technical reasons may also affect this:
- wrongignition adjustment. When late, the engine consumes more fuel. One degree offset will give a 1% increase in consumption;
- incorrect spark plug gap can increase consumption by 3-10%;
- if low-octane gasoline is filled in, an increase in consumption will give + 5%;
- driving on a cold engine will raise consumption by 20%;
- with a large piston wear, an increase in flow rate can reach up to 10%, and for each reduction atmosphere;
- unadjusted wheel alignment will raise consumption by 10%;
- a worn clutch will bring an extra 10% upwards;
- carburetor power system, faulty pump will increase up to 50%;
- misadjusted valves and outdated gas distribution together will result in a 10-20% increase in flow;
- increase in fuel consumption will give reduced pressure in the tires of the car;
- 10% gives a clogged air filter.
It is likely that the fuel consumption sensor will show an increase in consumption and purely for "domestic" reasons:
- the air conditioner involved will increase the consumption from 1% to 2%;
- open windows will increase the resistance to the oncoming air flow and entail an extra 3-5%;
- get 10% extra when driving on a road with poor grip (rain, ice);
- headwind will take 10%;
- by attaching a trailer, you will lose 25-30%
- will bring loss of the trunk attached toroof;
- an overloaded car will significantly increase fuel consumption.
The summed up results show that it is worth doing the calculation of fuel consumption, but you should check the technical condition of the car in time and master the techniques of economical driving.
Don't press the gas pedal hard. The faster the acceleration, there is more energy the car needs to do this, which it takes by consuming gasoline. Fill up with fuel at proven gas stations, its quality greatly affects consumption.
Check fuel consumption periodically.
When moving, try to maintain a constant speed.

Fuel control. Fuel consumption monitoring system
The fuel consumption monitoring system is designed to save money that transport companies spend on organizing road transport. Technical control methods are widely used by drivers working in freight and passenger traffic.

TCS for Casco or OSAGO is the amount of loss of commodity value. It is the difference between the profit from the sale of a car restored after an accident and the cost of the same new vehicle. Many factors have an impact on reducing the price of a car that has been in an accident, such as: external deformations of the car (scratches, dents), damage to internal components that inevitably need subsequent repairs
Why increased fuel consumption? Causes of increased fuel consumption
A car is a complex system where each element plays a huge role. Almost always, drivers face various problems. For some, the car drives to the side, others experience problems with the battery or exhaust system. It also happens that fuel consumption has increased, and suddenly. This puts almost every driver in a stupor, especially a beginner. Let's talk in more detail about why this happens and how to deal with such a problem
