What happens if sugar gets into the gas tank, the consequences of this can be very disastrous for the engine. It all depends on its quantity and the duration of operation of the car filled with “sweet fuel”. Usually, in this way, minors express their hostility towards the owner of the vehicle who has displeased them in some way.

Numerous myths

Sugar in the gas tank, the consequences of this, if you believe numerous myths, can be very terrible. The worst of them is a car explosion. According to the version, when gasoline is mixed with sugar, the car detonates, ignites, and then explodes. Therefore, some advisers recommend pouring “sweet death” into a rubber glove or condom and carefully placing it in the gas tank. After some time, the latex will be corroded by petroleum products and an explosion will occur. The criminal himself will be out of reach and completely safe.

The second version of the legend about disabling a car with the help of sugar is the jamming of the engine. Supposedly mixing with the liquid, it dissolves or forms a sticky consistency that can completely close the pipeline and clog the fuel filter. If the fuel system survives, then once it enters the combustion chamber, under the influence of high temperatures, it will burn or melt. The latter will result in a solid substance resembling caramel. If it gets on the piston and cylinder wall, it can jam the power unit.

Refutation of legends

So what are the consequences of sugar getting into a car's fuel system? In order to understand this issue, you can conduct a simple experiment that requires the following:

• 500 g of gasoline (octane number does not matter);
• 100 g sugar;
• glass jar with a capacity of 700 - 1000g.

Having prepared everything you need, you need to mix the so-called ingredients and mix them thoroughly. The fact that there was no explosion is already a refutation of the first myth. Another innovation will be settled sugar at the bottom of the jar. Thus, we can conclude: it does not dissolve in gasoline and does not enter into any chemical reactions with it. Therefore, pouring it into a fuel tank can cause the same harm as from ordinary sand poured there.

Real harm and dealing with the consequences

Having understood the legends and what actually happens when sugar gets into the gas tank, you can logically complete the sentence about the consequences that it can cause. With prolonged use of the vehicle, the engine will become difficult to start and its operation will be unstable. This will happen due to clogged fuel filters, which will have to be replaced. This is the only thing that threatens the car owner in terms of financial costs.

Now about the time spent on cleaning. If you find traces of sugar in the neck of your tank, you must completely flush the entire fuel system.

You can do this as follows:

• Completely drain all gasoline into a prepared container;
• Fill it with water 2/3 full; to speed up the process, you can slightly rock the car so that the liquid splashes inside and washes the walls;
• Drain the water.

After repeating the procedure 2-3 times, flush the fuel system by performing the following manipulations:

• Pour clean water into the washed tank;
• Using a fuel pump, pump the liquid through the tubes.

Important! The connection to the fuel filter must be open. Drain the liquid with the remaining sugar out. Only after performing such procedures and replacing the filter is it recommended to continue operating the vehicle.

Healthy! In a carburetor engine, the sugar must settle in a sump located under the fuel filter.

Protection from hooligans

To protect trucks and domestic cars from intruders, car owners put a lock in the neck of the fuel tank that can be locked with a key. This prevents the contents from being stolen and any nasty stuff in the form of sugar falling inside. Other people, when installing an alarm system, connect the gas tank flap to the vacuum door drive system, which blocks all locks after pressing the corresponding button on the remote control.

Not only vehicle owners, but also manufacturers are concerned about fuel safety. For example, we can consider the VAZ 2101-07 generation (classic) and modern cars produced by the Tolyatti plant. On older versions, the gas tank was mounted directly behind the rear fender, and it was possible to drain liquid or add sugar there without any problems. To do this, you need to unscrew the plug and remove the removable filter from the neck.
In most modern cars (manufactured in the Russian Federation), the fuel tank has moved under the trunk. Thus, its neck has become much longer, and the mesh is not removable. If some craftsmen manage to drain gasoline from them, adding large amounts of sugar is already problematic.

From all this it follows that most legends about major repairs or engine explosions are fiction. Even if sugar gets into the gas tank, the consequences are not as terrible as we used to think. But it is better to prevent such a situation and to isolate the fuel system in advance from the atrocities of persons unfriendly to you by installing a locking mechanism.

For quite a long time there have been rumors that if you put sugar in the gas tank, the car will fail. That is, sugar, according to many, should react with gasoline and thus clog the gas tank and disable other parts associated with it, that is, completely immobilize the car.

Offend the offender

Naturally, at first glance, this method seems ideal, but is it really valid? Perhaps yes, if you continue to listen to these legends. But! In fact, this is just a legend that has nothing to do with reality!

Sugar dissolves in water, but not in gasoline. Yes, of course, you can pour sugar (or sand) into your abuser’s gas tank, but...you shouldn’t expect a “positive” result on your part. Both sand and sugar do not dissolve in gasoline. The maximum they can do is , but the car will still move. All the car owner needs to do is change the filter and “voila”, the car is like new again!

In simple words, if you want revenge, pouring sugar into your gas tank will not help you at all.

How to understand that sugar has been poured into the gas tank

Naturally, sugar “by itself” cannot get into the car’s tank. Someone has to try for this. As a rule, this is done by hooligans or competitors (before the start of races or other activities when there is a need to use the vehicle).

If you have enemies or you see someone as envious and ill-wisher, it is better to initially rid yourself of the possibility of getting this trouble -. Most “scoundrels” will stop such actions!

It is worth noting that most car owners, when they hear the phrase “sugar got into the gas tank,” immediately condemn the car. But is this really so? We conducted our own experiment, the consequences of which allowed us to draw certain conclusions... And which ones, we will now share with you.

What happens if sugar gets into the gas tank?

There is a legend that says that sugar that gets into it can greatly harm it. They believe that sugar, after sugar gets into the gas tank, forms carbon deposits there, which will lead to a complete failure of the engine.

In fact, this sweet ingredient begins to caramelize or even burn when exposed to high temperatures (this is known not only to professional chefs, but also to housewives). For such a problem to occur, sugar must penetrate from the gas tank to the very heart of the vehicle - its engine. But from this moment the fun begins.

Experiment: sugar in the tank of a car

Well, let's move on directly to the experiment, which will finally put all the dots in place and give answers to all the questions. At the same time, we recommend that you pay attention, that is, you should not forget that gasoline is a highly flammable substance. That is, your actions should be as careful as possible in order not to harm your health.

What you need

So, let's start the experiment. To do this you will need the following products:

• glass container;
• petrol;
• sugar.

Why does the container have to be glass? In order to be able to monitor the amount of material used.

So, pour gasoline into the container and add sugar. We wait until the sweet element dissolves (to make this operation faster, you can stir the sugar in gasoline).

And at this stage the main surprise will await you - no matter how much you stir the sugar or wait for it to dissolve - nothing will happen, no chemistry. Sugar does not dissolve in gasoline!

Result

These are all simply legends! Under no circumstances will sugar getting into the gas tank stop your vehicle. Naturally, it will get on the fuel system filters and clog them, but other negative effects should not be expected from it.

A well-known way among motorists to “layer” their enemy is to pour a good portion of sugar into the gas tank of his car. This method of revenge, as they say, is extremely effective and destructive, and only very bad people are capable of putting this option into practice, pouring a generous portion of sweet revenge into their opponent’s fuel tank. And, voila, after he starts his car, after some time, figuratively speaking, his life will not be easy. Is it so? It’s unlikely that anyone has seriously thought about carrying out such an experiment, so we consider it a great success to show you a video we found on YouTube, in which they talk about the consequences of adding regular table sugar to and then running the engine on this mixture.

The video example uses an internal combustion engine from a lawn mower as an experimental model. Before conducting the experiment, the video blogger made several preliminary measurements, removing the cylinder head and first visually inspecting the carbon deposits and the condition of the piston, valves and cylinder walls. You can watch the process from 0.35 to 55 seconds of the video.

Next, a large spoonful of sugar was added to the gasoline; in terms of volume relative to the amount of fuel, it took up approximately 1/10th of the amount. An attempt to dissolve sugar in fuel brought virtually no results. Sugar is poorly soluble in gasoline.

Pay attention to the volume of gasoline in which they are trying to dissolve sugar. Can you imagine how much sugar is needed to get an equivalent mixture if we are talking about a standard car gas tank?

Next, the mixture along with sugar was poured into the tank, the engine was started, and an experiment lasting more than 100 minutes began. While the engine was running, a small amount of bluish smoke was observed at 3.45 minutes in the video.

After all the fuel had been used up, crystallized sugar was visible in the gas tank; a significant part of it remained inside without passing through the fuel line.

Results of an experiment with adding sugar to fuel

Compression dropped slightly when cold, 65 PSI versus 68 PSI in the original version. When hot, the engine did not feel worse in terms of compression.

When removing the engine “head”, formations of baked sugar were discovered in the combustion chamber. On the cylinder head, on the piston and on the valve.

The conclusion summed up by the video blogger is that there is harm caused in this way, but it is minimal and is more likely to be reflected in the long-term period of operation. The blogger does not give specific advice if sugar is suspected or detected in the fuel tank, but he asks a rhetorical question to his viewers. What would you do if you found sugar in your gas tank:

1. Would you flush the fuel tank?

2. Have you changed the fuel filter?

3. Would you remove the cylinder head and carry out an inspection?

4. Or would you use additives?

What would you do?

Since childhood, we remember that a pack of sugar poured into a gas tank can poison the existence of the car owner for a long time. In the famous French-Italian film comedy “Razinya” of 1965 with Bourville and de Funes in the leading roles, this technique worked perfectly. And everyone found it funny.

It is difficult to say how many gas tanks have since been subjected to such abuse: there are many kind people in the world. The algorithms for eliminating such “jokes” seemed quite creepy: what does it cost just to replace fuel lines clogged with a sticky sweet substance. But really, what should someone do who, as they say, “got caught in the middle”?

We set up a simple experiment. They took a glass jar with 95 gasoline, poured three pieces of Chaikofsky sugar into it (as it says on the box - with an F!), made in the city of Valuiki, and began to wait for the sugar to begin to behave as if it fell into a tea cup.

And-and-and... they didn’t wait. Even after six hours, all three pieces retained their original shape, without even trying to create a new brand of gasoline with increased calorie content. It is clear that when driving, they will all sooner or later fall apart from shaking, but they will definitely not have any more desire to dissolve in the 95th.

Of course, such experiments have been carried out many times before us. The verdict has always been unequivocal: there is no harm from sugar and cannot be. However…

However, not everything is so simple. Yes, sugar does not dissolve in gasoline... But it has excellent contact with water! And if there is one in the gas tank, and she is a frequent guest there, then the situation changes a little. A layer of liquid with a higher density than gasoline appears at the bottom of the gas tank. In this case, the fuel pump will definitely begin to suck it in.

Will it start? This is easy to check - instead of a cocktail straw, we take a fine fuel filter (for example, from a Lada Granta) and boldly immerse it in a jar of potion... Alas: the sweet water quietly “leaked” out! And if so, then in general there are no barriers to sugar, no matter how many filters stand in its way.

Thus, all publications of an exposing nature, including the show from “MythBusters,” turn out to be, let’s say, not entirely correct. Of course, water in gasoline is an undesirable guest, but in some cases it can keep company with another uninvited guest - sugar.

How to remove water from gasoline is a separate question. We already . Writing about sugar is, of course, more fun, but water in fuel can also cause a lot of trouble. However, in the near future we want to return to this topic, only a little from the other side.

We invite everyone who has their own opinion on the “sugar” issue to speak out. The main question is the same: is it possible to harm the food system from sugar or not?

Sugar in the gas tank - for many car enthusiasts this sounds like a death sentence. Sometimes on car forums there are chilling stories about engines seizing up as a result of someone's cruel joke. Let's use an experiment to figure out whether these stories have a basis, or if this is just one of the tales that motorists have a dime a dozen.

So, how can sugar harm the engine? Supporters of the legend say that sugar, entering the internal combustion chamber of the engine, burns there to form dense carbon deposits on the walls of the cylinder and piston, causing the engine to simply jam. And you can easily believe this - under the influence of high temperature, sugar begins to caramelize or even burn - this is well known to chefs when they bake pies. All that remains is to deliver the sugar from the gas tank to the engine. And with this, it would seem, everything is clear - of course, sugar will get into the engine along with gasoline. But there is one thing! However, let's do an experiment. I just ask you, if you want to repeat the experiment, perform it only in the open air and in compliance with all safety standards - gasoline is a flammable liquid!

We will need:

• Sugar;
• Petrol;
• Any container, preferably glass.

Add gasoline to the container, and then sugar.

Stir everything well and wait for the sugar to dissolve.

You could easily spend your entire life waiting. The fact is that sugar does not dissolve in gasoline! Thus, all the legends about engines seizing up due to adding sugar to the gas tank are fiction! Of course, for a car, adding sugar to the gas tank will not go unnoticed - the sugar will get on the filter elements of the fuel system and clog them. The engine will no longer start normally, will run intermittently, and the filters will need to be replaced. But this is a completely different story that has nothing to do with sugar burning in the engine.

Happy experimenting!
