What should I do if I add the wrong gasoline and diesel? What to do if you fill up the wrong gasolin

You should be careful when refueling to avoid the wrong refueling. However, if the wrong oil is really added, the owner should clean it up immediately, and never use it in the wrong way to avoid damage to the vehicle. The following is a collection of solutions to the wrong fuel in the car, welcome to read.

1. Gasoline plus diesel.

If you accidentally add diesel to your gasoline car, then the problem is more serious. Theoretically, due to the different combustion methods of gasoline and diesel, after adding diesel fuel to gasoline vehicles, there will be phenomena such as shaking the car, black smoke from the exhaust and even failure to ignite. If used, it will damage the entire oil system and may even cause the engine to be scrapped.

Therefore, it is recommended that if the owner finds that the wrong oil has been added, he should contact the 4S shop as soon as possible to clean the fuel tank and oil circuit system, and then conduct a comprehensive inspection of the engine, and do not ignite the fire to avoid hurting the car. What's more, this damage is not covered by the insurance company.

Second, the high grade oil is added to the low grade oil.

When the high oil is added to the low oil, such as 97 plus 93, 93 plus 90, etc., if the difference in the number is not big, the vehicle will have insufficient power, high fuel consumption, etc., the owner does not have to worry too much, as long as it is not used for a long time, it will not cause great damage to the engine. If the difference in the number is large, add No. 97 to No. 90, and when the car has not started, the gasoline in the fuel tank should be exported on the spot, and it is recommended that the owner contact the car 4S shop to clean the fuel tank and oil circuit system.

3. Add inferior oil.

One of the most serious cases of adding the wrong oil is adding low-quality oil to your car. Filling a car with low-quality gasoline will reduce the function of the engine, damage the pistons, gasoline pumps, etc. However, generally after adding inferior oil, it can still be seen from some signs.

If you find that the valve is ringing and the power is insufficient, you should first consider that the gasoline grade is too low. If the engine does not start well, then it should be suspected that the quality of gasoline may be substandard, such as many impurities, impure oil, adulteration of gasoline, etc. At this time, the owner should not force it to start, and should first contact a special car 4S shop.

Fourth, diesel plus gasoline.

Conversely, what happens when a diesel engine is added with gasoline? At first, the engine was running, but it was immediately boring. After driving for a while, the engine became louder, the idle speed became unstable, and white smoke began to emit from the exhaust pipe.

If the engine is found in time when the damage is small, and the fuel is replaced immediately, the engine can continue to be used without special adjustments.

The driver's license network reminds everyone: you should be careful when refueling to avoid the occurrence of such a thing as filling the wrong fuel. However, if the wrong oil is really added, the owner should clean it up immediately, and never use it in the wrong way to avoid damage to the vehicle.

Never underestimate the fact that your car is filled with the wrong gas. Many drivers or novices make such low-level mistakes. Even the staff at the gas station will fill the gasoline car or diesel car with diesel because of their own negligence, causing the car to be paralyzed and go on strike.

If you accidentally fill up the wrong tank of diesel, remember not to ignite the car to prevent the diesel from entering the oil circuit. Then tow the car to a shop or repair shop in 4s, wash the diesel, and then fill up with gasoline.

If you only add a little bit of diesel, no more than 5% or 10% of the fuel tank, and find it in time, in fact, it is not a big problem. Just fill up the gas and it won't make a difference.

In fact, most friends who refueled incorrectly will not find out in time, only after driving for a period of time and finding that the vehicle is abnormal, such as serious engine knocking, or the engine has stalled, they realize it.

In this case, rescue should be called immediately. The car should be shut down immediately and towed to a professional repair shop where repairs will be carried out by professionals to minimize damage.

The wrong fuel filling of the vehicle will lead to the damage of the high-pressure fuel pump, high-pressure fuel pipe and other components of the car, because the gasoline is corrosive, and after entering the mixture with diesel, it will erode the high-pressure fuel pump, nozzle, high-pressure oil pipe and other high-pressure fuel components.

For the same type of oil, if the car that drinks the low-grade oil is added with the high-grade oil (such as the 97-grade oil added to the 93-gauge car), then the car is usually fine. However, if you drink high-grade gasoline and add low-grade gasoline, it depends on whether the two labels are too different and the amount added.

If the difference between the two labels is too large or the whole tank of low-grade oil is added, it is recommended that the owner put the wrong gasoline or buy relevant fuel additives to improve the quality of the oil and reduce the damage of the low oil to the engine.

If the gasoline car is added with diesel, or the diesel car is added with gasoline, the first thing is to avoid the ignition of the vehicle, and then call the ** to notify the 4S shop or maintenance plant, release the mixed fuel, and clean the fuel tank and oil circuit system, and then conduct a comprehensive inspection of the engine.

Storage and use.

1. Prevent water and mechanical impurities from being mixed.

2. It is strictly forbidden to mix with gasoline for lighting or as fuel for kerosene furnaces.

3. Diesel must be precipitated, filtered, and impurities and water removed before use to ensure the normal operation of the diesel engine fuel supply system.

4. At low temperature, in order to improve the low-temperature fluidity of diesel, a small amount of kerosene is allowed to penetrate into the diesel, but the flash point may be unqualified. However, it is never allowed to add gasoline to diesel to improve the low-temperature fluidity of diesel.

5. Diesel oil of the same grade and different grades, because their quality indicators are basically the same except for the freezing point and cold filter point, so when the resources are insufficient, they can be mixed with oil at a suitable temperature.

6. Strictly prevent exposure to the sun and open flame heating, and store at a lower temperature as much as possible. In winter, the necessary preheating can be carried out when diesel is used.

The above content reference: People's Daily Online-Diesel Land Rover was mistakenly filled with gasoline It was found after driving more than 10 kilometers.

Due to the different fuel supply systems and different compression ratios, gasoline cannot be used on the diesel engine, which will damage the precision parts, cannot burn normally, and even damage the engine. If you find that you have added the wrong one, you should put it all away and refill the diesel fuel. If the car has been running for a short period of time, the oil pipe filter element, etc., should also be drained and cleaned.

Try not to let the gasoline connect to the fuel injection pump and fuel injector.

Drain, refill, purge oil and all cartridges. Otherwise, there is a possibility of a diesel engine**.

Let it go and re-add it. Drain the gasoline in the car, then open the fuel tank cap and blow the fuel tank to speed up the volatilization of gasoline, replace the oil and use diesel fuel to clean the oil pipes and cylinders, fuel injectors, fuel tanks, etc.! Replace parts if necessary.

You can't start the fire, otherwise the engine will be very damaged, because the combustion power of gasoline is much stronger.

Drain the gasoline in the car and then open the fuel tank cap to blow the fuel tank to speed up the volatilization of gasoline, replace the oil and consider the oil pipes and cylinders, spray.

Fuel nozzles, fuel tanks, etc. are cleaned with diesel! Replace parts if necessary.

If you find that the vehicle is filled with the wrong oil, you should contact the auto repair shop as soon as possible to clean the fuel tank and oil circuit system, and then conduct a comprehensive inspection of the engine, and do not start rashly to avoid injury to the car. If a diesel car is filled with gasoline, the problem is more serious. The car is able to operate normally at first, but after driving a certain distance, the car will become sluggish and the idle speed will become unstable.

It can be divided into three stages: the first stage is to detect the diesel car by mistake after the gas station notices the misuse of gasoline for the first time, do not start the car and immediately contact the original 4S store to excrete gasoline and diesel mixed fuel and remove the oil pipe, etc., so as to minimize the damage to the power system; In the second stage, after a short section of gasoline has been on the road and the wrong gasoline is added, in addition to the first stage of oil drainage and pipe cleaning, the diesel filter and oil-water separator need to be replaced. The third stage is the negligent situation of driving for a long distance after adding the wrong fuel, then the diesel pump and nozzle and other equipment must be replaced, and at the same time, in the second and third stages, the engine itself will cause a certain degree of damage, which must be fully inspected by the technical experts of the 4S shop.

First of all, don't start, contact the 4S shop to call a tow truck as soon as possible, and in the process of waiting for the trailer, make the responsibility clear with the gas station and keep the relevant evidence; Secondly, tow the car to the 4S shop and then clean the oil circuit of the whole car, and then add gasoline for a test drive. Third, if it is the responsibility of the gas station, claim with the gas station, and if it is your own responsibility, see if you can take insurance.

If diesel is added to the gasoline engine, the vehicle will not be able to start under normal circumstances. Since diesel has a lower ignition point than gasoline, compression can ignite and no ignition system is required, while gasoline engines have an ignition system. If the vehicle is started, the igniter will ignite the diesel directly, which will cause knocking and damage to the engine.

Its external manifestations are that the vehicle is shaking and black smoke is emitting from the exhaust pipe. Moreover, diesel is denser than gasoline and sinks to the bottom when stationary, so even if you don't add much diesel, it will be diesel that enters the engine first. If you don't pay attention at this time and forcibly drive the car away, the entire oil circuit system of the vehicle will be destroyed, and even the engine will be scrapped.

Consequences of filling a petrol car with the wrong diesel:

On the one hand, the pressure of the fuel injector of the gasoline engine is much smaller than that of the diesel engine, after the diesel is added to the gasoline, due to the insufficient pressure of the fuel injector, the diesel cannot be completely atomized, and the combustion is not sufficient.

On the other hand, the ignition point of diesel is low, and ordinary gasoline engines are ignited by spark plugs, so that before the spark plugs are ignited, the diesel itself begins to burn violently, causing abnormal pressure in the combustion chamber, which is commonly known as detonation.

The owner should pay careful attention to the diesel engine oil and the gas engine oil, and do not mix it up. Although the two also work under high temperature, high pressure, high speed and high load conditions, there are still big differences. The compression ratio of the diesel engine is more than twice that of the gasoline engine, and its main parts are subject to high temperature, high pressure and impact much greater than that of the gasoline engine, so the materials of some parts of the engine will be different.

Clean the oil circuit and replace the J gasoline.

<> "What should I do if I add the wrong diesel to a gasoline car?"

1. The difference between diesel and gasoline.

Diesel: density, autoignition temperature 250, viscosity 40MPa·s@20, cetane number about 50 (ignition performance).

Gasoline: density, autoignition temperature 420, viscosity 5MPa·s@20, octane number 90 97 (anti-knock index).

The basic difference between diesel and gasoline is that diesel has a high viscosity that is not conducive to mixing, but it is easy to ignite, and gasoline has a low viscosity and is volatile but not easy to ignite.

2. The difference between diesel engine and gasoline engine.

Diesel engines do not need additional spark plugs to ignite, and can raise the temperature to the ignition point of diesel fuel by compressed air alone, and then inject diesel pins, diesel spray and air mixture while igniting and combustion, which is called compression ignition. A gasoline engine needs an electric spark from a spark plug to ignite before it can burn, which is called ignition. The compression ratio of the gasoline engine is generally not too high, generally not more than 11, so as to avoid spontaneous combustion of oil and gas.

3. What happens if a gasoline car is filled with diesel?

If the gasoline car is filled with diesel by mistake, it will not start under normal circumstances. If it is started, due to the low ignition point of the diesel fuel, before the spark plug ignites, the high-pressure mixture will reach the auto-ignition temperature and begin to burn violently, causing the pressure in the combustion chamber to collapse normally, and the engine will detonation, and the engine will be destroyed when it collapses.

4. What should I do if I mistakenly add diesel?

In the case of no start, the diesel fuel is only in the fuel tank, and the oil can be pumped out directly and the fuel tank can be cleaned.

If you add fuel by mistake and start it, you will find that due to the insufficient pressure of the fuel injector, the diesel cannot be completely atomized, and part of the diesel will directly enter the cylinder in the form of liquid, polluting the entire oil circuit. At this time, you should stop immediately, call for help, contact the repair shop to dry the fuel tank, clean the oil circuit, replace the gasoline filter, and do a comprehensive inspection of each auto part.

Gasoline engines and diesel engines have different structures and different fuels, so we must pay attention to the oil added in daily life, and contact the repair shop in time once you realize that you have added the wrong one. It is especially reminded that the insurance company will not compensate for the loss caused by the wrong oil.

If the car can drive normally, it means that it does not have much impact on the car, but the car should observe the dynamics of the car at any time during driving.

If diesel fuel is added to a gasoline car, black smoke or engine vibration will occur, and it will not start.

Gasoline and diesel are both refined from **, but their ignition points are different. Generally speaking, at atmospheric pressure, the ignition point of gasoline is 427; The ignition point of diesel fuel is 220.

Therefore, when designing the engine, the gasoline engine adopts the spark plug ignition method, and the diesel engine adopts the cylinder compression ignition method.

When the gasoline car mistakenly adds diesel, the engine will burn in advance and burst out when the ignition time is not reached, and the engine will have abnormal noise (knocking), and even damage the engine.

Gasoline vehicles with diesel treatment methods:

First of all, do not start the engine, pump out the diesel fuel in the fuel tank with a straw, add gasoline as soon as possible to the quantitative height of the fuel tank (keep the residual diesel content less than 8% or lower), so that it will not affect the engine, let it stand for a few minutes, so that the gasoline and residual diesel are fully mixed, start the engine, observe if there is any abnormality, and keep the car running normally.
