When developing a car of the company, provide a certain mode of its work, indicating the optimal values \u200b\u200bfor various characteristics In the documentation that comes with the machine. The documents contain information on how to save the car units as much as possible in a working condition. Drivers and recommendations are issued on what fuel is better to fill in a car benzobac. The manufacturer only notes the octane number of recommended gasoline, since this is the only parameter that is specified in the gas stations when selling fuel.
As experiments show, gasoline with one octane number May differ from refueling to refueling. Most often, drivers choose a preferred fuel company, and refuel the car only on it. However, how to check the quality of gasoline and make sure that the refueling station is chosen correctly? This will come about the conversation in our article.
How to determine what a bad gasoline is covered in a car?
The quality of gasoline - the question is relative, and the fuel, with whom they perfectly cope russian carsmay cause problems in the work of German cars. Petrol sellers do not have the right to sell poor-quality goods, but the edges of the additives that they are obliged to enter into fuel are quite blurred. Each fuel company seeks their gasoline as low as possible in production, and at the same time corresponded to all standards. 
Bay of poor-quality gasoline, an experienced driver can always determine this in the following parameters:
- Unusual knocks when operating the engine due to a reduced octane number;
- Increased consumption of fuel vehicle with standard ride mode;
- Lowering the "sharpness" of the car - smaller accelerations and weak responsiveness on the gas pedal;
- The engine starts with difficulty;
- Spontaneous jumps of revolutions on idling.
The symptoms described above do not necessarily indicate problems with the quality of gasoline, but if they have been identified after refueling on a new station for the driver, you should take this fact For weapons and next time choose another fuel company to purchase fuel.
What problems may arise with a car due to poor-quality gasoline?
Poor fuel is a sentence for a number of car systems, if it is poured regularly. Drivers with small experience weakly imagine what dynamic characteristics should show a car when driving. They do not pay attention to the "extra" engine knobs or problems with excessive gasoline intake, and after learning in the service center that it is necessary to replace the expensive element due to bad fuel, regularly poured into the car.
Most often, low-quality gasoline leads to the next breakdowns:
- The fast failure of the spark plugs. If, when replacing candles, you found a red flask on them - this can signaling the regular refueling fuel;
- Problems with the health of the catalyst;
- Fault elements of the fuel system - fuel pump, nozzles, filters, sensors.
In fact, it all depends on how poor-quality gasoline caught at refueling. Some fuel can gradually inclous the engine parts and exhaust systemAnd another literally after a few days will force the owner to turn his car to the service.
Attention: If you refrain by poor-quality gasoline, be sure to drain it, and after rinse the tank, fuel line and clean the nozzles. If there is a check on gasoline, the car owner has the right to request the examination of the acquired sample, and in the event that low fuel quality is confirmed, the gas station is required to cover all the damage as moral and technical.
The choice of favorite gas station is not easy, and it should be approached with the mind. Do not be lazy to take samples from several stations in which you would like to regularly refuel the car, and then yourself check the gasoline at home. Moreover, the test procedures are very simple, and they do not require expensive equipment or special knowledge.
Check odor
The easiest way to identify low-quality gasoline is to hear foreign smells in it. Even with a mass of additives, the fuel for the car should not smell with oil, chemical reagents or gas. High-quality gasoline has a bright smell, which is difficult to confuse with something.
Check gasoline to low-quality impurities
Check gasoline for low-quality impurities can be right at refueling, before pouring it into the car. To determine the presence of low-quality impurities in gasoline, it is necessary to drop it on your hand. It is known that when interacting with skin in air, gasoline evaporates very quickly. Fuel in which low-quality additives are stored, after evaporation will leave the oil trail on his hand. Such gasoline should be avoided, otherwise it will quickly lead to the failure of the catalyst.
Another way to check gasoline to low-quality impurities is a careful study of its color. High-quality gasoline has a pale yellow shade or it is absolutely colorless, while various additives can make it reddish or bright yellow. Most often on auto filling stations When asked why gasoline is strongly yellow, the service personnel responds that it is associated with a special set of additives developed by the Seller. Believe in this or not - every car enthusiast can solve independently, but real high-quality gasoline should be pale yellow or not to have colors at all.
Gasoline check for oil
A very simple experiment can be carried out at home to determine - contains an acquired fuel oil or not. To do this, take a clean white sheet of paper and drip a little gasoline on it. Wait until the leaf is completely evaporated with fuel, and after take a look at the results. If a bold spot remains on paper, or it has changed the color, it means that oil contains oil or other unwanted additives. Perfect gasoline does not leave traces on paper.
Check gasoline for water
Determine that gasoline is diluted with water, very simply using a chemical experiment. To do this, take a small transparent container and pour gasoline into it. After that, add a bit of manganese into fuel and look at the reaction. Pure gasoline without water should not be painted in pink color, while the fuel with water is enough for the smallness of manganese, so that it is polished.
Attention: Do not pour (do not fall asleep) Too much mangalls, otherwise even gasoline can paint, and you will receive the wrong results of the experiment. The ratio of fuel and manganese at level 20 to 1 or higher is recommended.
Gasoline check for resin
Checking the fuel for the presence of a resin in it follows the street away from the gas station and other fastening objects. To check the gasoline, you must get a transparent glass and pour some fuel on it. After that, exhaust the experimental sample and wait until it is completely unlensed. When gasoline stops burning, check out what the mark from it remained on the glass. Pure fuel leaves a white trail, and when combustion of gasoline with resins, brown or yellow divorces remain.
The quality of gasoline is a question that worries absolutely all motorists. Unfortunately, not at each refueling you can find high quality gasoline. But there are several ways to help figure out how high-quality fuel.
The first method will help determine if gasoline contains a variety of impurities. These impurities can negatively affect fuel system vehicle. It will take only a sheet of white paper. Drip gasoline on leaflets and wait for evaporation. After drying, the sheet should remain perfect white. If there is a fat stain or a stain with some incomprehensible tint on the spot of evaporation, this gasoline contains harmful impurities. The early wear of the engine causes a resin in fuel. To check the share of the resin content, you can spend a small experiment. Throw gasoline on glass and set fire. He burns quickly, and circles will remain on the glass. If the circles white color, then the resin content is normal. If brown or yellowish divorces remain, the resin capacity exceeds the norm.
Thus, evaluate the quality of gasoline on their own - possibly. Only with all the experiments it is necessary to comply with security techniques.
Many know that the quality of gasoline does not check at refueling. But how, will not refill bad fuel? To do this, you need to check the quality of fuel only in a special laboratory. You will not be in front of each refueling to carry fuel samples into the laboratory. In order to at least approximately be aware of the quality of gasoline at refueling, you can check with undergraduate means. So you will certainly know the exact quality, but to distinguish high-quality 92 and poor-quality learn. But how to check the quality of gasoline at the refueling know not many drivers. That is why we decided to tell you how to check the quality. In this article we will talk about all the secrets of verification using own forces and knowledge. In order to find out this and much more carefully read our article further.
Start checking easier with smell. It is easy to do to everyone, since everyone knows how gasoline smells and how far you can teach his smell, if you do not give God to pour. By smell it is easy to estimate there is something in the fuel or not. Ordinary gasoline smells exclusively with gasoline, and gas should not be smelted or something else.
The next step of the check will be the color check. It is very easy to carry out, pouring a bit of fuel into a transparent container. High-quality gasoline without impurities should be pale yellow. If gasoline it has a different color, it means it is poor quality, or with impurities.
To check the fuel for water, it is enough to add a little manganese in it. If, after dissolving manganese, gasoline is painted in the raspberry color, it means that it has a certain amount of water. If the gasoline, when adding a manganese in it, was not painted, then there is no water in it, and you can safely refuel them your car.
Tip! Everyone knows that after entering gasoline on the skin, it will immediately dry, and will dry the skin. If after drying on the hand remained an oily mark, then fans with impurities and is distinguished by low quality. Drip some gasoline on your hand and check it out. If the oil trail remains on the hand, then do not even think about pouring it into the tank.
Then moisten a white blank paper substance. When it dries, look at the paper. If the paper changed the color, a drop of water or a fat stain remained on it, then such low quality gasoline. If 92 dry and white paper, means good quality fuel.
To check the fuel for the presence of a variety of resins that are very dangerous for the engine of the car, it is enough to do the following. Pour a little car on the glass and burn it. In no case do not make such a test for checking the resin near the refueling. It is better to type fuel into the container and do it in a place that will be far from faster materials. After you burn gasoline on the glass track should be white. If the trail is yellow or even brown, it means that it has a huge number of different resins. Also on the glass can remain drops of liquids. This suggests that the quality is bad and water may be present.
After these simple tests, you will know about knowing what your car goes. We wish you good luck during the test of fuel quality!
It is no secret that the quality of gasoline at various refills is significantly different. And not always expensive gasoline means better. A lot of factors can affect the price, but this is not our topic now, just know what is more expensive - it does not mean better. The brand of refueling, of course, plays a role, but there are many ways to deceive consumers at gas stations than and use "not clean" Deltsi. Sometimes on the bypass of the direct guide. And the use of low-quality fuel is fraught with the failure of the fuel system, much reduces the engine resource and is the cause of instability of work, reduce thrust, difficult launch, etc.
All this, besides the inconvenience, pulls the rather significant material costs for repairs, in addition, the consumption of poor-quality gasoline is always higher, and therefore you have to refuel more often.
The fact that poor-quality gasoline is bad, it is now about how easy it is to determine the quality of fuelWith this without using wise ways or laboratories.
- Listen to the reviews of the refueling of other motorists, and better professional drivers. Find out where your friends and acquaintances are refilled in your city. This is the simplest, however, an effective action.
- If you are in another region, stay on those gas stations where cars are with local rooms. Drive past the too cheap refueling, very cheap goods do not happen. It is clear that there should be a consumer corner on each gas station, the train, the technical passport of fuel.
According to multiple examinations and analyzes, it was found that at filling stations where the price of fuel was significantly cheaper than the average, the quality of gasoline did not comply with the established standards. For example, an abnormal level of sulfur and octane number, inappropriate, the presence of unforeseen additives and resins.
- It is noticeable that in large cities, gasoline is much better than somewhere in the area. This happens, because a revision or mobile laboratory simply does not reach remote refills. On weekends and holidays, the risk of refueling dilute gasoline is also increasing.
- Remove the fueling gun and before insert it into the neck of the tank, swipe on the surface of its internal diameter. If gasoline is diluted with diesel (as they are often done) or contains other octano increasing impurities - the surface being checked will be fat. If the feeling of "fatness" remains on the finger - gasoline is quite high quality.
- Bay Fuel on new refuelingYou should watch the machine, listen to the engine. By sound and change of thrust, the experienced driver is able to determine what quality gasoline is in the gas tank of his car. With a large share of the probability of quality, it is possible to judge the fuel consumption.
- Listen to the engine at idle, uneven work indicates uneven combustion of fuel and, accordingly, about its not appropriate quality.
- After refueling, pay attention to the color exhaust gases. Size or brown exhaust - gasoline quality, black smoke with soot - low grade. Naturally, this indicator works if you have everything up to refueling.
- Cropped on gas. If you feel the detonation of your fingers, it is a sign of poor fuel quality.
Methods independent check Quality gasoline
- Smell and color check. The gasoline itself represents a colorless liquid, only a -76 is somewhat muddy because it has more extraneous impurities. In the production of gasoline is painted into a certain shade. So, and -92 should have an orange-red shade, and -98 - blue tint, and -95 light yellow color with a slight greenish tint. Pour gasoline to the jar and consider against the light source. Blue and red shade indicates the presence of impurities. The red shade is evidence that methyl was added to low-quality gasoline in order to increase its octane number (so from A -92 was obtained A -95). Additives are very harmful for both the machine and the body. They spoil the fuel hoses, clog the filters and fuel system as a whole, poison the body.
The presence of sulfide sulfide, liquefied gas or naphthalene, as well as the smell of acetone or panel of rubber indicates the poor quality of gasoline. - The next simple method consists in the following, it is necessary to pour gasoline into a small container and carefully drop into your hand. The quality of gasoline will depend on how he behaves on the skin. Good fuel can act, as if driving it, and the one in which the various "bodiagas" added a fat stain on his hand.
Test gasoline on the abundance of clearly unnecessary harmful additives and chemical additives Also quite simple. 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.
- Test for burning gasoline. Use transparent glass or polished metal plate. Cap a couple of drops to the surface and fell. The test is carried out for the presence of oil in fuel and other oil impurities. High-quality gasoline is not containing resin, burns completely. After the combustion of gasoline, we look at what happened on the glass. If only white circles remained, it says that gasoline of proper quality and no impurities in it.
The appearance of circles and stains of yellow and brown color indicates the presence of a resin of different types in gasoline. Gasoline can not be poured, but wait for his evaporation. If, after drying on the glass surface, rust or dark divorces in the shape of a rings remained, this also testifies to the resin content.
- Water is an extremely unpleasant component for gasoline, or rather for the engine. On some refills you can buy gasoline, diluted with ordinary water. For such cases there is a manganese, which has a useful property, namely: dissolving in water. It paints water present in fuel, in pink or purple color. In gasoline, it does not dissolve, the color of fuel does not change, and mangartee just remains in the sediment - there is no water.
Manganese can be bought in any pharmacy, it is worth a penny. Instead of manganese, you can use the stylograph of a conventional simple school pencil. If there is water in the fuel, it is better to immediately change the gas station, as sooner or later problems can not be avoided.
- Finally, it would be nice to buy a carometer, for example ANT-1, to measure the density of petroleum products. Such an uncomplicated device for checking the quality of gasoline is quite a bit, and the benefit can have a lot. According to the form and method of use, it is similar to the range for checking the electrolyte density in the battery or the freezing temperature of antifreeze (toosol). Some refills, for example, in gasoline A -76 add additives and sell it under the guise of gasoline with a large octane number. From A -92 make a -95 even more.
The density indicators may vary depending on the temperature regime and may vary within the following limits:
for A-76 (AI-80) - from 0.700 to 0.750 g / cm3
for AI-92 - from 0.715 to 0.760 g / cm3
for AI-95 - from 0.720 to 0.775 g / cm3
for AI-98 - from 0.730 to 0.780 g / cm3
You can learn the density of the realized gasoline of the corresponding brand from the documents at any refueling, the temperature at which the density was measured or the density to 20 degrees would be measured. Celsius and compare real and declared.
For the same reason, the mass of fuel released at refueling can always be different. At the gas stations, leave is made in volume, and the volume is not permanent and depends on temperature. Therefore, if you refrain at the end of a sunny day, when the underground storage containers warm up, then in the morning, when gasoline in your tank will cool it less. In winter, for the same price you will always get more gasoline than in the summer. If possible, refueling the best in the morning. The rule is simple - the colder fuel - the more you get it and vice versa. Owners of refueling all this well know and various frauds, sometimes completely legitimate, welded.
In fact, not everything is so bad and find a gas station with high-quality fuel and accurate accounting is not so difficult. Having spent in search of a benzocolone for a month or other, you will relieve yourself from unnecessary trouble and material costs.
It so happened that many automakers do not want to equip cars intended for russian market, most modern motors. A B. specificationsit is indicated that the version of the machine is adapted for Russian Federation. This is due not only to the quality of roads and harsh weather conditions, but also with unsatisfactory quality of gasoline domestic production. It is worth noting that diesel fuel in our country is an order of magnitude better than gasoline, but in this case you can get to expensive repair of a diesel engine.
Unfortunately, still. The quality of fuel sold in Russian gas stations leaves much to be desired. And when this situation is not known to change for the better, maybe, besides the oligarchs selling poor-quality fuels. Also, the question remains open, why the state will not take responsibility for controlling the quality of the fuel sold. Not only bad quality from the factory, so also diluted at the refueling themselves.
But it is worth noting that recently, large networks of refueling stations are followed by the quality of their goods, but sometimes there are exceptions. Also, there are many single gas stations, especially those in depths that can fill you into the tank frankly dangerous liquid For a car motor.
Therefore, even modern drivers should know how to independently check the quality of gasoline. True, many ways are suitable for checking at home, but to check the new filling station, fit perfectly.
The first signs of quality inconsistency
To begin with, you need to remember the first, the most obvious signs of poor fuel quality, for a peculiar express test "on the eye".It is worth noting that the very first sign, but not obligatory is the cost of fuel. As they say, "free cheese only in a mousetrap" and here. Suspicious low price The fuel should be a serious signal and alert a potential buyer. First of all, because the cost of gasoline and diesel fuel Almost the same at all refills in a specific region. Therefore, the price is too low - this is a sign of the inconsistency of quality or different impurities (even water).
Also. You need to turn on the smell of fuel, every car owner remembers this unique fragrance. But if it seemed to you that the smell is very different, or the shades of burning rubber or other chemistry predominate, then this is a sign of exceedable content different oils and additives.
The most important feature. But unfortunately there is already postfactum - this is a job power aggregate And the car itself after refueling. If the engine begins to work differently, and possibly unstable, as well as the car dramatically lost several points in the dynamics and power - then the refueling station should be changed. But first of all, make sure there is no problem of your car.
Methods of self-diagnostics of gasoline
If you are not enough for your suspicion and there is a desire to make sure of your assumptions, you can use old proven ways. But it is worth noting that many checks are preferably carried out at home, but for some persistent people, it is also suitable for checking at refueling. Such methods will be given below in the article.Check for additives and impurities in fuel
This is one of the simple and rapid ways to determine the extra number of additives or impurities. For the experiment, you need a little fuel and a white sheet of paper. The experiment itself is to drop fuel onto a white sheet, and wait for a full evaporation of gasoline. If gasoline was high, then the sheet of paper will not be left traces and divorces. The thing is that gasoline is a volatile substance, and evaporates in full, but the additives and heavy substances remain.
Inspection
This check will help check the presence of oily impurities that should not be in good quality gasoline. To do this, you need to drop by gasoline on the convex glass, and then set fire to it. As with paper, there should be no traces and wet places on the glass, and if white divorces remained, then this is a sign of good quality. In the event of yellow or brown traces, this is the consequence of excess impurities, and it is desirable to abandon such fuel.
Water Adding Check
The easiest way to check is the verification of ordinary manganese. The fact is that mangartage is not dissolved in gasoline, and accordingly, gasoline does not change its color. Accordingly, if the mangartage was dissolved and the liquid acquired a pinkish shade - then with a high probability, it is possible to approve the availability of water in the fuel.
Check with skin
You can check the quality of gasoline "to the touch", you should not fear to stain your hands in gasoline, this species Fuel is often used as a degreaser. Therefore, in the hands there should not be fat, and the gasoline itself for the sensations of "dry" and tightens the skin.
How and where to complain
It is worth noting that you can complain about the quality of fuel and you need. For this, it is worth contacting Rospotrebnadzor. This state structure has the right to conduct fuel examination at automotive gas stations, but only every three years. But in the case of the consumption of a large number of consumers to a certain refueling, the authority is obliged to respond to the complaint, so it is necessary to complain.But this measure may not have an impact on unfair entrepreneurs, as Rospotrebnadzor is obliged to warn about checking three days before it. What time does the preparation and provision of reference samples of gasoline and diesel fuel.
