The quality of gasoline almost always leaves much to be desired. The use of low-quality fuel is fraught with failure fuel system Engine. Repairs will require significant material costs, since modern fuel systems are very sensitive to the quality of gasoline used.
Visually determine the quality of gasoline is almost impossible. Give samples into a special accredited laboratory is expensive and take too much time.
You should not despair if you wish, you can check the quality of gasoline at home. Before refueling gasoline on a specific gas station, it is enough to perform its safety check for a car motor.
At automotive gas stations, 3 types of gasoline are implemented: A-92, A-95, A-98. They differ among themselves octane number.
The higher the better than gasoline and less than its consumption. The refill of poor-quality gasoline significantly reduces the resource of the car's motor.
The following negative consequences of using low-quality fuel are available:
Fuel filter pollution
The filter element first "signals" about problems as refueling fuel. Low-quality gasoline containing a large amount of impurities quickly pollutes fuel filter. Its bandwidth is significantly reduced. Cleaning quality becomes extremely low and an increasing amount of impurities penetrates the fuel system
Reduced traction machine
The use of low-quality gasoline for a long time leads to a significant reduction in the thrust of the machine. She simply "refuses" to quickly go and reduce the dynamics of overclocking.
The smaller the volume of the motor is the stronger expressing the "slowness" of the car. Power is lost, especially when using trailer with a load. The machine often stalls and the engine unevenly works at idle
Motor detonation
Very unpleasant phenomenon resulting from a long use of low quality gasoline. The mixture of gasoline and air as a result of compression is prematurely flammed before the fear of fire. The engine detonation significantly reduces its resource and leads to premature capital repairs
Fuel equipment failure
Subcase gasoline with long-term use leads to problems in the operation of the fuel system of the machine. This is especially brightly noticeable on new cars, where the fuel system is very sensitive to the quality of the fuel. Such doubtful savings ultimately turns into significant material costs.
An independent check of the quality of gasoline allows the driver to identify its own circle of safe automotive gas stations. Such actions allow minimizing the risk of low-quality gasoline refueling.
You can select the following methods for checking the quality of gasoline at home:
White sheet of paper
A blank sheet of ordinary white paper is taken. Its surface is wetted by a small amount of gasoline. You need to wait for a leaf and look at the light.
If the leaf surface remains white, it means the quality of the fuel is good. If after drying the gasoline on the sheet there are divorces, the fuel contains impurities. Not recommended refueling
Glass spherical surface
To test the quality of gasoline in this case, you can use ordinary hand watches. On their glass spherical surface is enough to place a drop of gasoline.
If after drying on glass surface Rusty or dark divorces in the form of rings remained, gasoline in large quantities contains resin. The latter during combustion form to dig a negatively affecting motor
Plastic bottle
To check the quality of gasoline at home, it is enough to dial a small amount into an ordinary plastic bottle. As a rule, there are enough 500 milliliters.
The dialed fluid should be carefully considered in the light. It has a light yellow color. In gasoline, you need to add a small amount of manganese-sour potassium.
If the color of the fuel has not changed, everything is in order. Coloring fluid in pink or reddish color is evidence of water availability
Hand
On the skin of the hand you need to apply a small amount of gasoline. If he, quickly evaporate without leaving traces, it can be safely refilled into the tank. When the oily oil stain is formed on the hand, the fuel contains a mass of impurities.
When checking the quality of gasoline at home, you must remember that the safety technique needs to be remembered. Fuel should be kept away from light sources, electrical appliances and explosive items. Inactive use of gasoline can turn into fire.
Thank you for your attention, good luck to you on the roads.

Each driver is important that his car worked for everything else and was able to serve him for a long time. To do this, it is necessary to monitor not only its technical properties, but much depends on the quality of gasoline. It is from it that the work of the engine depends. It is bad that even the most famous companies do not guarantee that a high-quality fuel will fall into the tank, and not fake. A poor fuel may result in the failure of the entire fuel system of your car. This leads to the repair of the engine. It is now, during a sharp rise in gasoline prices, it is worth it to be extremely careful.
How to check b quality b.enhai on the refueling
As soon as we arrived at the required refueling , Before pouring fuel to the tank, remove the fueling gun and before entering it into the throat itself of the tank, touch your finger to the place that in contact with the gasoline refueling. So, if gasoline is diluted with a diesel or octane-raising impurity, the surface of the rim will be fat. If there is no feeling of fatty and stickiness on the fingers, then gasoline is good and you can safely use it for the machine.
You can try to dial fuel into a transparent bottle or canister and look at the light. In good fuel should not contain any impurities. The fuel must have a pale yellow shade.
How to reveal water in gasoline :
- Water availability
In the combustion you can check as follows: add a solution of manganese. If he starts reproach, it means there is water.
- Drip fuel On the tree and, if it does not evaporate or rolls into a ball, then this is also a sign of water in a stuel.
Also try to take a white sheet of ordinary paper and moisten it slightly in gasoline. Wait for it to evaporate. Focus on the color of the sheet. If he remained snow-white - a high-quality gasoline, a fatteid spot indicates the presence of kerosene in the fuel. A drop of water on a sheet - Avoid this fuel at all.
In order to determine by presence of not necessary resins , take the glass and pots on it. Gasoline. Go on fire. White circles after combustion - fuel of excellent quality, stains of yellow or brown - it means there is a resin. This can lead to malfunctions in the engine or in the fuel system.
How to determine the quality of BE NZIN by smell
Bad gasoline can immediately feel the smell. He will have sharp and unpleasant odorswhich are not entirely characteristic of petroleum products. This suggests that fuel diluted with naphtalin, or hydrogen sulfide, or mercoptan gray.
Defect quality gasoline to home conditions - tactile
Drip gasoline to your hand. A good and not diluted product must dry the skin on the hand. If fuel is smeared with bold stains, then there are impurities of diesel fuel.
In order to protect themselves from poor-quality fuel, refuel only on verified gas stations. If there are doubts as fuel, demand from sellers to gas stations all relevant fuels documents that confirm the quality and reliability of this type of petroleum product. True, it cannot guarantee a hundred percent guarantee that this fuel complies with all standards. But such protection can help save your car from a malfunction in the engine.

Each motorist for sure at least once in his life came across unscrupulous tankers, which instead of high-quality gasoline poured into the tank it is unknown that. Such a situation can not only spoil the mood, but also pour into the vehicle breakdown. Therefore, it is very important to be able to determine and stop the activity of such cuters. How to check at refueling without having a pocket laboratory? There are some simple testswe will talk about below.
Six fuel check rules
FirstThat should alert a car enthusiast when you get a refueling - these prices are much lower than the average in the region. Should think what caused such an attraction of unheard of generosity? The answer is likely to be disappointing.
SecondWhat gives you to know about low-quality fuel, this smell. Regularly dealing with gasoline, its smell is easy to remember. If it becomes more sharp, there are clear notes of magnificent rubber, gas, household chemicals, or something else, it is better to get around such a refueling party.
However, gasoline can be diluted not only by additives, but also by ordinary water, which, naturally, does not possess any outsiders. Third The defining criterion can be the color of gasoline. It is enough to pour a bit into a transparent container and add a pair of throttle drops there. Clean gasoline will not paint. If he bought raspberry color, it means that it was diluted with water. However, you can do without chemical experiments: it should simply be remembered that the undeveloped gasoline has a pale yellow color with a slight greenish tint. Any other shades of color are not in favor of quality.
Fourth Method: You can apply a little gasoline on your hand. Clean gasoline evaporates in the blink of an eye and begins to slightly dry the skin. If an oily precipitate remains on the palm, it means that there are extraneous impurities in the fuel.
If you do not want to experiment on yourself, you will come to the rescue fifth Option: Petrol Popper on a clean white sheet of paper. By drying, undiluted fuel will disappear, without leaving traces. If you observe the spot, it means that the gasoline mixed something more superfluous. For especially "advanced users" there are specially developed in the Russian State University of Oil and Gas. THEM. Gubkin test express strips. They act like a Lacmus paper: if you get a pair of fuel drops, they change color. Or do not change if the fuel does not contain impurities.
Sixththe test method is quite extreme: it will require additional equipment And retire from refueling to a safe distance. You need to drop some gasoline on the glass and set fire (obviously, why it can not be done on the spot - fraught with a large explosion). Sensual quality gasoline after combustion leaves whiten spots. Resins and impurities in fuel will demonstrate brown, yellow and other stains.
Even if gasoline does not cause mistrust, be sure to check the date of its production before purchase. The absence of impurities at all does not mean the quality of gasoline, but an overdue fuel is no less detrimental to the engine than diluted.
If you already flooded fuel
It happens that you did not guessed gasoline on time, and while suspected began to custody. It is possible to sin on fuel in two cases: if you are on idling Watch out exhaust pipe Due-black with soot smoke and if the tachometer reflects "jumping", testifying to uneven engine operation. This picture is characteristic of poor-quality fuel.
How to independently check the quality of gasoline Price the first indicator of high-quality fuel is its price. Every driver knows mid-price This or another gasoline brand, as well as its cost on different refueling networks. If the price tag for gasoline is on an unrealistic low mark - you can be sure that they sell nothing like "Palenca." Consequently, such fuel should be crowned with the tenth road, and it is not bad to call the auditory authorities well and indicate a suspicious gas station. Smell to everyone who at least once sniffed gasoline, signs his specific smell. Yes, depending on the brand of fuel, the fragrance can be slightly different, but you will not be able to shuffle a special difference, if, of course, there will be too many additives in gasoline and impurities. Each of them has no less specific and resistant smell. You are guaranteed to account for this fragrance if there will be more in gasoline of such "ingredients" than it should be. The color of gasoline should be a pale yellowish shade. This is the law. The truth is worth knowing that some refills specifically tinkering their fuel to avoid fakes. If gasoline is, say, the blue, most likely, such a high quality fuel, because his seller will not risk leaving obvious evidence on "Bodhage". Tinting gasoline must have the following colors (shades): A-80 - Yellow AI-92 - Orange-Red AI-98 - Blue Two Last Gasoline You are already unlikely to meet, but for the general development to know does not prevent: A-66 - Green A-72 - Pink operation of the motor, fuel consumption This fuel quality check method is suitable for experienced drivers who know their car like five fingers. This driver will not be difficult to determine the quality of fuel in the nature of the operation of the car's motor, fuel consumption, and even the smell of exhaust. But this diagnostic method is very dangerous. First, such gasoline is already harming the car, secondly, in case of a serious breakage, you will be very difficult to prove the guilt of the tanker in court, even if there is a check. Therefore, it is better to use other "grandfathers" ways. For example, such as a sheet of paper. A sheet of paper To determine the quality of gasoline yourself, you can take a blank sheet of paper on which a little fuel drop. Then begin to blow on the piece of paper until the whole gasoline will not evaporate. Carefully inspect the place where it was fuel. With high-quality gasoline, there should be no stains on paper - it should be white. If the paper shade has changed - there are impurities in gasoline, or it does not comply with standards. It is better not to use such fuel. Now there are inexpensive indicators that can be purchased in the auto shop. Enough to hold a strip of the indicator filling pistolwhere there are always droplets of gasoline, and look at the reaction of the indicator. If the color has changed to dark green - gasoline is poor quality. Convex glass very important moment - Resin content in fuel. This is a key indicator in the safety and duration of the engine. In order to find out, there is not much resin in the fuel, it is enough to drop gasoline on the convex glass and set fire to it. A specific circle should appear on the glass, the color of which will appear about everything. If you are watching a yellowish and brownish color - in gasoline too much resin, if the hue is whitish - everything is fine. If drops left after combustion on the glass, this suggests that the fuel divorced diesel or added oil. Manganese or chemical pencil is perhaps the most ancient ways to check the quality of gasoline at home. Take a transparent vessel, pour gasoline there, inspect his color (it should be pale yellow) and add a small amount of manganese or a piece of chemical pencil into the liquid. These reagents react well to water, and if the fluid has changed dramatically in color on pink or purple, which means water in gasoline more than it should be more precisely, it should not be there at all. To the touch, the easiest way to check gasoline even at refueling, just drop it on the skin. If the fuel starts spread and turn into a fat stain, such a fuel diluted with a considerable amount of impurities or additives. Immediately you can unfold and leave with gas stations, well, but if it's not a pity of the time and nerves, then go to lay down with the gas stamp management. Good gasoline Must immediately push on the skin and quickly disperse. Personal mind remember, the quality of gasoline is very important for the engine of your car. Do not refill on unknown gas stations that offer too cheap gasoline. Remember, the miser pays twice, and once saving several tens of rubles on the fuel, you risk to upset for several tens of thousand rubles when repairing a car. Therefore, remember these simple ways. independent check Gasoline, and let you never come across Palenka.
Probably, you need to have a separate laboratory to find out what is equal octane number Gasoline or diesel fuel in reality. And to thoroughly determine the chemical composition of the fuel is not easy even in laboratory conditions. Nevertheless, there are simple and affordable ways to determine the quality of fuel, to use which you can at home or at refueling.
We investigate the composition of the combustible mixture themselves
Before, let's call what exactly we want to fight. Gasoline, as you know, can dilute with water. If the water in the fuel is much, the crystals of manganese will dissolve in it (here is the first test). So, if there is a packaging with a substance KmnO4 at hand, you can do this: gasoline is poured into the transparent container, and then crystals are added and the mixture is added, trying to get a solution. If the crystals dissolve, a pink shade will appear on the lumen. What will immediately say about the presence of condensate.
Many know that gasoline without additives is not for sale in principle. Actually, if the mixture of hydrocarbons would be delivered in its pure form, it would lose positive properties very quickly. The required set of additives into commodity gasoline is added to refineries. At the same time, some additives that are harmful to the engine, for the sake of achievement of certain purposes may notice to fuel in a completely unreasonable proportion. But we have a cunning test to combat unscrupulous vendors.
It is enough to wet a sheet of paper flammable, dry it and see then, which will remain on the sheet. Good gasoline as a result of the test will not leave traces at all. Spend such a test with the 95th gasoline and see what happens ... It should be noted here: be that as it may, high-tech engines do not rely "feed" fuel with a lower octane number than is recommended by the manufacturer. It became fashionable to use 92th gasoline instead of the 95th, since the first contains less additives. So, the use of harmful additives leads to a gradual, although more rapid wear, well, and a lower octane number will provide periodically emerging detonation ... Make conclusions.
At the end of this chapter, consider another test method. You can learn to determine if there are various resins in the fuel, oil, etc. Cropped on a glass of a small drop of gasoline, set fire to it. The test was successful if the glass surface covers the divorces, the color of which is not enough of the white. On the presence of a resin in an invalid concentration will say the presence of such shades: yellow, brown, orange. There is benzene - it means there will remain soot (it will also be in the engine). well and diesel fuel It burns not completely - after it is small transparent drops, just like after burning oils.
Quality testing methods, closest to reality
The driver approaching the column and the package of the A4 sheets is rather strange. It will be more incomprehensible if someone tries, being in the territory of refueling, to wait for something. If there is no good fire extinguisher nearby, it is not recommended to conduct the last of the listed tests in principle. Someone advises to adjust a sheet of paper, impregnated with flammable, and the flame color to determine the level of quality. We do not recommend that it is true, and now we will consider tips performed in reality.
In fact, the listed rules need to be guided all the time:
- Either on the column itself (near the fastening of the hose), or the plastic window should be placed near the pistol handle. If it is filled with fuel not completely, or you can notice the presence of bubbles - do not refill. Gasoline of any brand with natural light can only be transparent, but it can be barely noticeable yellow or blue tint. Know that everything else is one of the "hellish mixtures".
- In summer, if possible, you need to refuel in the morning. In a later clock, the contents of the tank will consist of two substances - from the fuel and its evaporation. It is impossible to do nothing, and the honesty of the seller in this case It does not affect anything.
- There is such a method of deception, as nothing. Therefore, try not to resort to the help of tankers or follow their actions.
It seems, it is known about the very simple way Check whether gasoline is really proposed high-quality. You need to pour one brush with a fuel, rub the liquid between your fingers and wait. After evaporated, the real gasoline allegedly leaves anything in his arms, and the skin becomes dry, both from ethyl alcohol. Maybe such a method worked earlier
