After buying a car, many car owners only know how to drive, but do not know how to maintain it. Some old drivers are more knowledgeable about cars and have a good understanding of various parts of the car. They also notice some alarm signals coming from the car, and if they find any problems with the car, they quickly send it for repair. The more they drive, the better they drive. Today, let me take a look at a few signals for everyone. Once these signals appear in the car, it indicates that the spark plug needs to be replaced.

1、 Severe oil burning

If you find that a car burns engine oil for a long time and changing to a different brand of engine oil has no effect, it may be a problem with the spark plug. Spark plugs are the most important ignition components in cars. Severe oil burning in cars indicates the need to replace spark plugs, otherwise it will damage the engine.

2、 Frequent jerking

Sometimes when starting a vehicle, the car may experience jerking, and the jerking is very serious, which can also indicate that there is a problem with the spark plug of the car. If the spark plug is not replaced for a long time or worn severely, it can cause the car to experience a jerking sensation within a certain speed range, making people feel that the power is insufficient and acceleration is weak. Sometimes the car suddenly comes to a sudden stop, and then it is best for the owner to quickly replace the spark plug and check if there are any other safety hazards in the car.

3、 The idle state jitter is significant

To check if the spark plug needs to be replaced, the owner can keep the car idling for a long time. If the car shakes severely and produces noise during idling, it indicates that the spark plug needs to be replaced.

4、 Sudden engine shutdown during driving

It is impossible for a car to stall for no reason during the driving process. Once the vehicle is found to have stalled, it definitely indicates that some components have problems. If the spark plug is not replaced for a long time or has been damaged, it will cause the car to have poor ignition and suddenly stall during driving.

In summary, spark plugs are a very important component in cars, and the material of spark plugs is constantly updated. The lowest level nickel spark plugs must be replaced every 30000 to 50000 kilometers, while higher quality platinum spark plugs can be replaced every 60000 kilometers. I suggest everyone replace spark plugs with better quality ones. These types of spark plugs have a lower failure rate and longer usage time. How often do people replace their spark plugs?
