What s the deal with the smell of gasoline in the engine oil in a Volkswagen?

Hello, Volkswagen.

The reason why there is a gasoline smell in the engine oil inside.

1. The continuous use time of the engine is too long, and the matching gap between the piston and the cylinder inner wall.

Get bigger. Since the pressure in the combustion chamber is always greater than that of the box, a small amount of mixture enters the crankshaft.

in the box. 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.

Performance. Lubricity.

The ability of 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.

From the engine oil aspect, the engine oil is easy to start and reliable to supply oil at low temperatures, which is called the 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.

Viscosity and temperature. The property of lubricating oil that changes its viscosity due to temperature fluctuations is called viscosity-temperature. Good viscosity means that the viscosity of the oil changes with temperature to a small extent.

The effect of temperature on the viscosity of oil: the viscosity decreases as the temperature increases; The temperature decreases and the viscosity increases. in base oils.

The addition of viscosity index improvers can improve the viscosity temperature of the oil.

Hope it helps!

This is a problem with his combustion chamber to prove that his combustion is not complete, well, there will be gasoline, well, after all, after he burns not completely, he will spread the gasoline to this oil, so there will be a gasoline smell in the oil, you are the cylinder piston, well, the friction is not good, or there is a sharp seam with a gap, hurry up and repair it.

There is a smell of gasoline means that there is gasoline in the engine oil, the general problem is that the fuel injector is depressurized and leaking, you can check it one by one to see if there is relevant gasoline to the engine pipe.

The oil inside the Volkswagen smells of gasoline. That means that your car may be burning engine oil and needs to be checked and repaired.

There is a smell of gasoline in the engine oil in the car, what's going on? If there is a smell of gasoline in the engine oil in the Volkswagen, it means that the engine has burned the oil, so it is said to smell of gasoline.

The common problem of Volkswagen, no way. Anyone who understands cars knows that Volkswagen cars burn engine oil and have many faults.

Just open it.

There is a smell of gasoline in the engine oil in the car, what's going on? If there is an organic smell of oil in the engine oil in the Volkswagen, is it gasoline leaking into the oil?

The reasons for the smell of gasoline in the engine oil are: 1. The oil film awareness of the lubricating oil is reduced due to the long-term failure to replace the lubricating oil, and the piston lubrication is not in place. 2. There is a strain on the wall of the cylinder, resulting in blow-by.

3. If the engine is used continuously for too long, the matching gap between the piston and the cylinder inner wall becomes larger. 4. Often short-distance driving, cold car start without hot car, resulting in gasoline not being baked for enough time, gasoline can not volatilize, etc.

Detailed analysis of how the engine oil smells of gasoline.

1. Long-term failure to replace the lubricating oil leads to a decrease in the oil film awareness 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.

2. It may be that you often drive short distances, and the cold car has a large amount of fuel injection, which is easy to enter the engine oil, and if the car is not hot enough to stop, then the gasoline in it has not been baked for enough time, and the gasoline cannot volatilize.

3. If the engine is used continuously for too long, the matching gap between the piston and the cylinder inner wall becomes larger. The only place where the engine oil and gasoline in the car comes into contact is the combustion chamber, due to the uneven mixing of the empty channel ratio, the concentration of the mixture is too large, and the pressure in the combustion chamber is always greater than that of the box, resulting in a small amount of mixture gas entering the crankshaft box.

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 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.

Because this engine oil is gasoline. Gasoline is a taste. There are a lot of things that have their own flavors that have their own formation.

It may be that the lubricating oil has not been replaced for a long time, resulting in a decrease in the oil film awareness of the lubricating oil and inadequate piston lubrication. There is a strain on the inner wall of the cylinder, which leads to blow-by.

Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil, and additives can make up for and improve the shortcomings of base oil performance, give some new properties, and are an important component of lubricating oil.

The reasons for the smell of gasoline in the engine oil: 1. The oil film awareness of the lubricating oil is reduced due to the long-term failure to replace the lubricating oil, and the piston lubrication is not in place; 2. There is a strain on the wall of the cylinder, resulting in blow-by. 3. If the engine is used continuously for too long, the matching gap between the piston and the cylinder inner wall becomes larger. 4. Often short-distance driving, cold car starts without hot car, resulting in gasoline not being baked for enough time, and gasoline cannot volatilize. Consequences of blowing-by:

1. The gasoline vapor that escapes into the crankcase condenses and causes the oil to become thinner and the oil performance deteriorates; 2. The water vapor in the exhaust gas condenses in the engine oil to form bubbles, destroying the supply of engine oil; 3. The sulfur dioxide in the exhaust gas meets water to form sulfurous acid, and the sulfurous acid meets the oxygen in the air to form sulfuric acid, which will corrode and damage engine parts; 4. The pressure in the crankcase increases, destroys the seal of the engine, and leads to the leakage of oil.
