A clogged oil filter is a problem that needs to be taken seriously, as it can lead to a series of engine issues. The following is some information about clogged oil filters, along with possible consequences and solutions:
The function of the oil filter:
The main function of the oil filter is to filter impurities in the engine oil, such as metal shavings, dust, carbon deposits, etc., to keep the oil clean, thereby protecting the internal parts of the engine and extending the service life of the engine.
Reasons for the clogging of the oil filter:
Engine oil that has been used for too long: Engine oil that has been used for too long will deteriorate, its viscosity will increase, and it is easy to form deposits in the filter, causing blockage.
Using inferior engine oil: Inferior engine oil contains more impurities and is more likely to clog the filter.
Severe engine wear: Severe engine wear will produce a large amount of metal debris, increasing the burden on the filter.
Filter quality issues: Poor quality of the filter itself, insufficient filtration capacity, and prone to clogging.
Long-term low-temperature driving: In a low-temperature environment, the viscosity of engine oil is high and its fluidity is poor, which makes it easy for deposits to form in the filter.
Long-term high-temperature driving: High temperatures can accelerate the deterioration of engine oil and produce more deposits.
The consequences of a clogged oil filter
Reduced oil pressure: A clogged filter can lead to poor oil circulation, a drop in oil pressure, and an inability to effectively lubricate engine components.
Increased engine wear: Insufficient oil pressure can lead to poor engine lubrication, accelerate engine wear, and even cause serious faults such as cylinder pulling and bearing seizure.
Engine overheating: Insufficient oil pressure can affect the heat dissipation function of the oil, causing the engine to overheat.
Increased engine noise: Poor lubrication can cause an increase in engine operation noise.
Reduced engine power: Severe insufficient oil pressure can lead to a decrease in engine power.
How to determine if the oil filter is clogged?
Observe the oil pressure gauge: If the oil pressure gauge shows too low a pressure, it might be a sign that the filter is clogged.
Check the oil filter indicator light: If the oil filter indicator light is on, it indicates that the oil pressure is too low and the filter needs to be checked.
Observe the color of the engine oil: If the color of the engine oil is too dark and cloudy, it may indicate that the filtering effect of the filter has declined.
Disassembly and inspection: The oil filter can be disassembled for inspection. If a large amount of impurities accumulate on the filter element, it indicates that the filter is clogged.
Solution:
Change the engine oil and oil filter: This is the most direct and effective solution. It is recommended to change the engine oil and oil filter regularly as required by the vehicle maintenance manual.
Use high-quality engine oil: Choosing high-quality engine oil that meets the vehicle's requirements can reduce the risk of filter clogging.
Regularly check the oil pressure: Regularly check the oil pressure to promptly identify and resolve any issues.
Avoid prolonged driving in low or high temperatures: Try to avoid prolonged driving in low or high temperatures to reduce the risk of engine oil deterioration.
A clogged oil filter is a problem that cannot be ignored, as it can cause serious damage to the engine. Therefore, car owners should regularly change the engine oil and oil filter, use high-quality engine oil, and regularly check the oil pressure to ensure the normal operation of the engine.
