What is the situation when car oil smells of gasoline?

Hello, the reason why there is a gasoline smell in car oil is:

1. If the engine is used continuously for too long, the matching gap between the piston and the cylinder inner wall becomes larger. Since the pressure in the combustion chamber is always greater than that of the box, a small amount of mixture enters the crankcase. Solution: Release the gas mixture.

2. The lubricating oil has not been replaced for a long time, resulting in the reduction of the oil film degree of the lubricating oil, and the piston lubrication is not in place. There is a strain on the inner wall of the cylinder, which leads to blow-by. Solution: Change the lubricating oil.

Extended Information: Performance LubricityThe ability of an engine oil to reduce friction, slow down wear and prevent metal sintering under various conditions is called engine lubricity. The viscosity of engine oil is an important indicator of lubricity.

Low-temperature operability ensures that the engine is easy to start and reliably supplied oil at low temperatures, which is called low-temperature operability of engine oil. The low-temperature operability of engine lubricants includes two aspects: good for low temperature starting and reduced starting wear. The main indicators to evaluate the low-temperature operability of engine lubricants are low-temperature dynamic viscosity, boundary pumping temperature and pour point.

Viscous lubricating oil has the property of changing its viscosity due to temperature fluctuations, which is called viscosity-temperature. Good viscosity means that the viscosity of the oil changes with temperature to a small extent. Effect of temperature on oil viscosity:

The temperature increases, the viscosity decreases; The temperature decreases and the viscosity increases. The addition of viscosity index improvers to the base oil can increase the viscosity temperature of the oil.

The oil scale is very normal, and the engine oil of the world's gasoline-burning car does not smell of gasoline at all. Landlord, you are worried.

If there is a gasoline smell in the internal oil duct of the engine, consider the following reasons: if it is direct injection in the cylinder, consider the high-pressure oil pump, the injector leakage and the carbon canister solenoid valve is caused by it! If it is an ordinary naturally aspirated engine, consider the fuel injector, whether the pressure of the gasoline pump is too high, whether there is a problem with the solenoid valve of the carbon canister, etc.!

Question: My car is a Big Dipper X5 car, and there is a problem with the fuel injector, gasoline pump, and carbon canister solenoid valve, right, how to check it? Is it easy to repair?

Question: Is this oil used for change?

Q: Is there any connection between burning engine oil in my car and these problems? After repairing it, put the oil in it, just change the oil directly?

The answer is related, if the engine burns oil, there are many reasons, such as poor oil lubrication, bad oil use in the car, poor oil quality caused by too much carbon sludge inside the engine, which will accelerate the wear of mechanical parts inside the engine, such as piston ring damage, oil ring locking, etc.

Ask me what I do and how I say it so that I don't get caught up in the repair shop.

If there is a strong smell of gasoline in the engine oil, it is usually accompanied by an increase in engine oil! Isn't this the case with Honda's oil incident some time ago, and it is recommended that you go to the after-sales service as soon as possible to check it.

In general, it is normal for engine oil to contain the smell of gasoline.

After the mixed oil and gasoline enter the cyclone, the gasoline vapor with low density (light) is directly sent back to the intake manifold (or straight back to the cylinder) from the upper channel to participate in the secondary combustion.

In fact, part of the oil hanging on the cylinder wall and piston evaporates into a 10 m diameter oil vapor, which is mixed with gasoline vapor and pressed into the crankcase by the "positive pressure" of the combustion chamber at the same time, and only this part of the oil vapor is contaminated.

It may be that the cylinder gasoline burns poorly or the amount of fuel injected is too much, you can check whether the valve has carbon deposits.

Hello, this is due to the aging of the rubber tube in the engine compartment of the canister, which will deteriorate after a long period of use, and older vehicles are prone to this problem. Once it ages, there is a risk that gasoline can leak into the engine compartment. The air conditioning system then allows the smell of gasoline to enter the car.

Therefore, once the rubber hose is aged, it needs to be replaced in time!

Leaks may occur at the joints of the gasoline pipes, causing the smell of gasoline to enter the vehicle through the air conditioning system. If the owner notices the smell of gasoline in the car, he should check the interface of the gasoline line - open the engine compartment cover, it is easy to tell whether the gasoline pipe interface is leaking, because a layer of sludge will appear on the surface after a period of leakage. If the gasoline pipe interface is found to be leaking, the connection should be tightened or repaired.

Owners who have recently replaced the gasoline pump or disassembled the gasoline pump in the car, do not panic if there is a gasoline smell in the car, it is likely that the residue has not been cleaned up after the disassembly and assembly. This is less likely to happen, and the typical replacement interval for a gasoline pump is 100,000 km. However, the gasoline filter element is connected to the gasoline pump, and its replacement cycle is shorter, and the gasoline pump needs to be disassembled and assembled when replacing.

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

Hello friend, according to the question you provided, here is a detailed answer to the question that your oil smells of gasoline, this is a problem caused by the leakage of the fuel injector, or the bloating caused by the leakage of the high-pressure oil pump, this needs to be checked, is the fuel injector leaking? In addition, is there any leakage of the high-pressure oil pump?

Question my Suteng 2010, a week ago found that there was a gasoline smell in the oil, changed the gasoline high-pressure oil pump, re-maintained, after the oil alarm, the oil was diluted, the amount is more! I changed an oil sensor, and five days later, there was an oil lamp alarm today, what happened?

In this case, there must be more leakage of fuel injectors. You can remove the spark plug and see if there is any blackening on the spark plug? If there is blackening, it is a leak from the injector.

In the case of this car, there are still more problems with fuel injector leakage.

Question: How can the fuel injector be checked for oil leakage?

In the case of the fuel injector, it can only be removed for testing and atomization testing. Or take the spark plug out to see if the spark plug is burned and blackened.

Question: Can oil dilute bloating cause oil lamp alarms? Master.

If too much gasoline enters the oil, it will definitely cause this failure. Therefore, it is better to check the fuel injector first.

If there is a distinct gasoline smell in the engine oil, it is not normal. It is possible that the oil is mixed with a little gasoline due to the leakage of the injector, but there is a difference in personal taste, if you feel that there is a problem, it is best to find a professional to check it.

The oil inside the car smells of gasoline, and it is likely that it was in the car. The high temperature generated during the operation process mixes the gasoline into the engine oil, so it has a gasoline smell.

It should be that there is an oil leak somewhere in the car, or the oil is open, and the engine starts to emit the smell of smoke, causing it to enter the cabin, and it will smell a lot of gasoline.

If there is a smell of gasoline in the engine oil in the car, it means that there is a leak, so be sure to observe it carefully and take a look.

Generally, there will be no gasoline, so if there is gasoline in the car, it must be a leak of oil to be like this? Generally, there will be no oil leakage.

What's the deal with the smell of gasoline in the engine oil in the car? In this case, you can see if your engine oil is not very good, and then you can check it, but you can rest assured, it is absolutely impossible to put gasoline in the engine oil.

What should I do if the car oil smells of gasoline?

It is a normal phenomenon, this is because when the engine is working, the piston will move up and down, and the piston movement needs the assistance of the oil, which will have a part of the mixed gas in the oil, so we will smell the smell of gasoline in the oil.

It's not normal, is the fuel injector leaking into the engine? Generally, engine oil will not smell of gasoline.

Hello, I have seen your inquiry, please wait for a moment and answer it for you immediately.

There is a smell of gasoline in the engine oil. The main current engine is a direct injection engine in this cylinder, that is to say, when the temperature is particularly low, the injection pressure is relatively large. Then the temperature is relatively low, and the engine does not burn sufficiently, and the excess gasoline will be scraped into the oil pan through the piston ring.

This will cause the oil to smell of gasoline. This is also the current majority of engines have this phenomenon, as long as the oil does not appear obvious increase, there is no oil emulsification, then there is no big problem, normal use can be.
