Oil consumption rate
During normal operation of an automobile engine, oil consumption is expected to be minimal. However, from time to time, car owners may experience increased oil consumption, which is a concern. Let’s take a look at the reasons why an engine can consume oil in excess of the norm, as well as ways to prevent this.
Causes of High Oil Consumption
- Oil leak
One of the most common causes of increased oil consumption is oil leakage. Oil can leak from various places such as gaskets, seals and oil seals. Even a small leak can lead to a significant increase in oil consumption. One of the possible causes of oil leakage is damage to the cylinder head gasket (cylinder head) or cylinder block. Therefore, it is important to regularly check the condition of the gaskets and replace them if necessary.
- Fuel system malfunction
Another possible cause of increased oil consumption is a fuel system malfunction. If more fuel enters the fuel system than is required for normal engine operation, this can result in increased oil consumption. Periodic maintenance and inspection of the fuel system will help to identify and eliminate possible malfunctions.
- Piston group wear
The wear of the piston group can also lead to increased oil consumption. If the pistons and piston rings are worn, this can cause oil to enter the combustion chambers where it is burned along with the fuel. Regular inspection and maintenance of the piston group in proper condition will help reduce oil consumption.
- Occurrence of rings
The occurrence of rings can also be the cause of increased oil consumption. The sealing rings between the piston and the cylinder can become lodged over time and misuse. As a result, oil begins to enter the combustion chamber and is burned along with the fuel, causing increased consumption. Regular inspection and maintenance of the engine will help prevent ring sticking and reduce oil consumption.
- Wear of valve stem seals
The valve stem seals located on top of the piston are designed to prevent oil from entering the combustion chamber. However, over time and heavy use, these caps can wear out and lose their functionality. Worn oil seals will not be able to securely hold the oil, which leads to its increased consumption. Checking and replacing worn caps regularly will help reduce oil consumption.
- Turbocharger
If your vehicle is equipped with a turbocharger, a malfunctioning turbocharger can also lead to increased oil consumption. An oil leak or worn turbocharger bearings can cause oil to enter the intake system and be burned during engine operation. Regular diagnostics and maintenance of the turbocharger will help prevent possible problems and reduce oil consumption.
Prevention and Diagnosis of Faults
Regular preventive maintenance and diagnostics are recommended to prevent excessive oil consumption and ensure normal engine operation. It is important to monitor the condition of gaskets, seals, oil seals, fuel system, piston group and valve stem seals. Regular oil and filter changes also play an important role in maintaining normal oil consumption. Inspecting the engine for leaks and regularly checking the operation of the turbocharger are also essential.
If you experience signs of increased oil consumption, including smoke from the exhaust system, a constant decrease in oil level, or a loss of engine power, it is recommended that you contact a qualified technician to diagnose and correct possible problems. He will be able to conduct a detailed analysis of the condition of the engine and determine the specific cause of increased oil consumption.
Prevention and regular maintenance of the engine should not be neglected. However, car owners should pay attention to some precautions to reduce the risk of increased oil consumption. This includes proper engine operation, following the manufacturer’s recommendations for changing oil and filters, and replacing worn parts in a timely manner.
In conclusion, increased oil consumption in an automobile engine can be caused by a number of factors, including oil leakage, fuel system problems, piston group wear, ring sticking, valve stem seal wear, and turbocharger problems. Regular preventive maintenance, diagnostics and timely troubleshooting will help maintain optimum oil consumption and prolong engine life. If you have any suspicions or problems, it is recommended to contact specialists who can provide professional assistance and solve the problem with increased oil consumption.
