This is an important component that is relevant, most likely, for every driver. She not only helps to keep her wallet full, but also helps out in extreme situations. This article will help you learn a lot of new things, including the secrets experienced drivers. They will tell you how to get to the nearest petrol station on empty tank.
Fill with water instead of gasoline
Imagine a situation where we are on the road and running out of gas. There is not a single gas station around, and we are careless and forgot to take canisters with us, naively relying on standard consumption rates. ? And all this could have been avoided if we paid more attention to the car.
Still, it happens to probably everyone. And in this case, if you know some secrets, then you can not panic and not beg passing motorists for help.
Of course, the instructions for a safe exit from situations when the fuel runs out may contain bikes. For example, such legends that involve adding ordinary water to the tank. Is it possible to deceive the engine, and on a subconscious level, thinking that it is gasoline, will it continue to move on? Funny, by God!
Nevertheless, we wanted to check this version. No, we're not from MythBusters and we don't do anything like that. So, driving instructors, the most famous and venerable ones, told us that, for example, pour water into Moskvich and drive on is quite real! It is necessary to fill in, according to their assurances, only one and a half liters of water. Just enough to get to the nearest station. Our eyes widened from such information provided by experts. Although still on imported car this method will not work. This can result in a costly repair. But the most interesting was yet to come!
Fuel tank
Let's go further. It turned out that, according to the theory, water has an even higher density than gasoline. And fuel (in the sense of gasoline, not water) will flow into the gas pipeline if there is not enough fuel. Ah, well then everything is clear! Indeed, it often happens that there is gasoline at the bottom of the tank, but there is very little of it to enter the carburetor.
And some lovers of old domestic cars, for example, the same "Moskvich" or "Zaporozhets", to save fuel, they put the hose not into the tank, but into a bottle. They put a plastic container next to the carburetor, securely fastened it and let in a hose that connected to the gasoline pump. Thus, gasoline was pumped out completely and not a drop remained. But the tank is another story.
Let's take a look at the design fuel tank. An empty tank is a container that is a spherical, rectangular or cubic shape. There will always be fuel in such a tank, no matter how mechanical or electronic components try to pull it out of there. You know how some motorists try? They lift one side of the car and draw out gasoline with a hose and suction a la "inflate the lungs and cheeks."
There is another way that will help you get to the nearest gas station if you feel that the fuel is running out. It means turning off all electrical appliances, of course, except for those that are responsible for driving safety.
After that, you need to try to drive at the same speed and not change gears, since.
In addition, if the driver goes on the road to such regions where refueling is rare, then he must take care to fill in the fuel larger brand. For example, if he always filled AI-92, then he can fill AI-95. This will reduce fuel consumption and help you get to the gas station.

Another method involves lowering a plastic bag of water into the tank. This will keep the water from mixing with the gasoline, but the bag will push the gasoline out. This method is just not very common, since it is difficult to remove the bag from the tank later. It can get caught on something and break easily.
Where does the fuel go
Now let's look at where fuel is spent at all? It turns out that the lion's share of the fuel is spent on overcoming various obstacles, changing energy and heating. In addition, some of the gasoline generally disappears without even doing any useful work.
In fact, it has a rather low efficiency. Where does all the gasoline go then?
Do you know that on cars with mechanical box gears need to drive properly? No, well, having basic driving skills is very important, we know that. It's about something else. If you drive for a long time in low gears, gasoline will go twice as much. And this does not mean that you need to include high gears. No. So, on the domestic "Zhiguli" perfect transmission, at which the least fuel is consumed, is the third, and not the fourth, as some think.
In addition, fuel consumption also depends on speed. At low or gasoline, it takes much more than at average speed. Again, it is recommended to drive the Zhiguli at 60–80 km/h. And on low speed energy is spent on overcoming the friction of tires on asphalt or other pavement. At high speeds, energy is used to overcome air resistance. That's pure physics for you.
Numerous ways to save fuel would be useless if the driver did not know that air resistance is on the body of his car. That is why designers are trying to improve the body of the car, making it more streamlined. Why sports cars lower than usual and differ in their form of construction? Yes, they do not look too aesthetically pleasing, but air resistance has a minimal effect on them.
In addition, the quality of the body coating affects the air resistance. Yes, don't be surprised. The better your car, the less air resistance will affect it. The hatches, windows and even the antenna that are open during the movement also increase the resistance. In addition, it is recommended not to put anything on the roof, and the mirrors of the car should only provide a normal view, and not be too huge, since they can also provide unnecessary resistance.
Those drivers whose car is endowed with air conditioning can be advised to turn it off if there is no urgent need. A stove can also take a lot of fuel. Therefore, the driver is advised to pay attention to all this if he is interested in saving fuel.
Underfilling of fuel at the station
Okay, you say. This seems to have been sorted out. And what to do if the gas station is underfilled, huh? How to be in this case? We will do everything to save, snatch more and more from the components of our comfort, and we will be fooled?
Unfortunately, underfilling of fuel at gas stations is a reality modern life in Russia. Almost every motorist is faced with such a problem. It is very relevant today and it is quite difficult for a person who is not technically savvy to deal with it.
But you can determine the underflow immediately. On two main grounds. If we run full tank and we know that it holds only 50 liters of gasoline, then the information of the tanker that he filled in 55 liters of fuel will be false.
The second method implies the presence of a canister. In practice, it has been proven that many gas stations deceive, perhaps not on purpose, drivers by pouring little gasoline. But it will be impossible to fill a smaller amount of fuel into a canister, especially into a container with a scale.
What are gas station owners doing to pour fuel honestly? Do they do it at all? Of course, not everyone is so dishonest. There are many ways gas station checks. Services specially created for this purpose are engaged in verification. They use 10-liter canisters to take fuel. And therefore, often at many gas stations, the delivery of gasoline is correctly configured for only the first ten liters. Then the underflow starts.
cunning gas station owners can deceive and special services. For example, having developed special program refueling management. When the check arrives, they turn on normal mode where underfilling is not possible. After that, as everything is checked, another mode is switched on, which does not add fuel.
Therefore, the driver would like to advise the following:
- refuel on your own, and do not trust this matter to the station staff;
- carefully check the plastic sight glass when refueling (if it is defective, air will enter your tank along with the fuel).
Look like that's it. All of the above tips can be put into practice, as they are tested experienced drivers with experience.
Details Category: Articles Published on 20.01.2016Today we will talk about what will happen if you drive all the time with an almost empty tank.
Many motorists drive the car every time until the fuel reserve light comes on. Is it worth it to do so?
In fact, it's best to always try to keep the tank full. There are at least three reasons for this.
1. Gasoline pump. On modern cars fuel pump is located in the gas tank and is cooled by gasoline. If you always drive with an empty tank, then the fuel pump will overheat and fail earlier.
2. Condensation. When the car's tank is empty, condensation from atmospheric moisture forms on its walls due to temperature differences. Over time, this water accumulates at the bottom of the tank (as you know, water is heavier than gasoline) and leads to problems with starting the engine, as well as corrosion if the tank is metal.
3. Power reserve. Sometimes it happens that there is a need to urgently go somewhere far away. If you have a full tank, then it is unnecessary to think about whether there is enough gasoline and look for a gas station. A full tank will also save you in case of force majeure on the highway, especially in winter. On a snow-covered winter road, the only source of heat is the car engine, which cannot run without gasoline.
Like to ride on a half-empty fuel tank? Spare money for a full tank? But do you know, let's figure it out.
From time to time, topics pop up on various forums on the Internet where motorists argue for a long time about operating a car on an empty or half empty tank. As a result, the opinions of the drivers were divided. Some believe that driving on an empty tank does not harm either the engine or the car as a whole, while others argue that it is evil while driving. So who is right?
The engine does not "know" how much fuel is left in the tank. He only "knows" if he is receiving enough fuel to start or not. .
Especially for older cars that run on low octane fuel, which likes to absorb moisture from the atmosphere, leading to increased humidity in the gas tank. More modern cars, running on high-octane fuel, are more protected from the formation of excess moisture in the tank.
As we know, water is the enemy of any metal. Once in the tank, she begins to do her evil deed. And the more often we drive, the faster the moisture, mixing with the air, will begin to corrode metal surfaces gas tank.
As the tank corrodes, the rust inside it will begin to gradually flake off, clogging in the first place fuel gauge. Also, the chemical elements of rust can accelerate over time, located in. But worst of all, if rust penetrates the fuel line into the engine.
In this case, she will simply corrode him.
By the way, many of these effects have a certain dependence on the climate, as well as how well you take care of your car (how often you change various filters etc.).
But rust in the tank is not the only problem for a car. In fact, the most worrying thing is the dirty fuel that we often pour into gas stations. There is a particular risk for those cars that refuel at non-network private gas stations, where unscrupulous owners of the gas station often sell fuel of dubious quality.
The worst thing is when dirty fuel gets into the tank. In this case, at least fuel filter and copes with its duties, it still exists, as well as the fact that dirt gets into the engine. It is highly undesirable to pour fuel immediately after filling it into a gas depot, which can also have rust. Yes, of course, every gas station must clean the tanks where the fuel is stored. But you and I know that many gas stations do not do this.
It is also harmful to drive on an empty tank due to overheating of the fuel pump, which can fail because of this. The thing is that the fuel in the tank, in fact, is a natural coolant for the fuel pump. That is, the fuel protects the pump from overheating.
It is also worth noting that when the engine is running, 98% of the fuel in the car is not used and returns to the tank. As a result, the fuel heats up. Naturally, when there is little fuel in the tank, it heats up too quickly in it. This in turn leads to insufficient cooling of the fuel pump, which shortens its service life. Among other things, this often causes an increase in fuel consumption and an increase in harmful substances in the exhaust.
Unfortunately, the heated fuel in the tank creates a lot of harmful fumes that affect the life of not only the fuel tank, but the entire fuel system.
But why can a small amount of fuel in the tank lead to a decrease in the range of the car, while, on the contrary, when the fuel in the tank is heated, its volume increases?
The thing is that when gasoline heats up, it expands. When the temperature drops, gasoline, on the contrary, shrinks in volume. However, the energy content of gasoline is directly related to its weight, not volume. Therefore, the energy content of gasoline, respectively, does not increase with increasing fuel volume.
By the way, it is also important not to pour fuel above a reasonable limit.
The upcoming rise in fuel prices has a negative impact on our motorist. Increasingly, motorists are trying to save money and fill up their car with 5 liters.
Many want to ask the question, What is better to fill up to a full tank or fill up 5 liters?
Probably every experienced motorist knows that Saving on gas station does not lead to anything good. . Appear problems with fuel system car, the fuel pump fails and this despite the fact that the fuel may not be very good quality, which significantly reduces the life of the engine.
If you have already sat down at the "steering wheel" you should not be worried about anything, and the lack of fuel, especially, therefore fill up to a full tank and enjoy the ride.
or "refill 5 liters ” leads to the following negative consequences :
- Fuel pump failure fuel pump repair carried out due to the combustion of its motor, due to a lack of fuel, the pump begins to "grab air" because of which it breaks down).
Another very popular question among motorists, - If the light comes on, how far can you drive?
Usually, if the fuel level light comes on, you can still safely drive 30-40 kilometers in normal quiet operation.
Some experts advise against relying 100 percent on the fuel gauge, as this information has an approximate calculation with some error. It’s better to overpay a little than to run around the gas station with canisters or even worse “eggplants”, which is strictly prohibited.
We must also understand the fact that the car will move even when there is no fuel left in the gas tank, but it will still be in fuel line. Therefore, dear motorists, I ask you not to save on your "horses", and if you save, then choose a more substantive economy.
Recently, many readers began to receive such questions - Why fuel tank 40 liters,and they filled me with 42 liters at a gas station, why are they fooling me?
Guys, before you blame the gas station workers and quarrel with them, make sure the volume filler neck. Since the volume of the fuel tank of 40 liters can be declared in the passport of the car, but 43-44 liters of gasoline can actually fit.
And do not think that I am defending gas stations, there are, unfortunately, unscrupulous gas stations that practice underfilling gasoline ( how to cheat at gas stations), and I recommend using only proven and recommended gas stations.
While filling the fuel tank do not confuse petrol and diesel hoses, this can lead to sad consequences, namely, to a breakdown of the motor.
