After buying a car, many car owners only know how to drive but not how to maintain it. Some experienced drivers have a good understanding of cars and are familiar with various parts of the car. They may also notice some alarm signals coming from the car and quickly send it for repair if they find any problems. The more they drive the car, the better it will be. Today we will list a few signals for everyone. Once a car shows these signals, it means that the spark plug needs to be replaced.

1、 Severe oil burning

If you find that your car has been burning oil for a long time and changing to a different brand of oil has no effect, it may be due to a problem with the spark plug. The spark plug is the most important ignition component in a car. If the car burns oil severely, it means that the spark plug needs to be replaced, otherwise it will damage the engine.

2、 Frequent jolts occur

Sometimes when starting a vehicle, the car may experience jolts, and the jolts are very severe, which can also indicate that there is a problem with the car's spark plug. If the spark plug is not replaced for a long time or is severely worn, it will cause the car to experience jerking in a certain speed range, making people feel that the power is insufficient, the acceleration is weak, and sometimes the car suddenly comes to a fast stop. At this time, it is best for the car owner to replace the spark plug as soon as possible and check whether there are other safety hazards in the car.

3、 The idle state has a large shaking amplitude

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

4、 Sudden engine shutdown during driving

During the driving process, it is impossible for a car to stall for no reason. Once the vehicle stalls, 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 ignite unclearly and suddenly stall during driving.

In summary, spark plugs are a very important component in cars. Nowadays, spark plug materials are constantly being updated. The lowest grade nickel spark plugs must be replaced after 30000 to 50000 kilometers, while higher quality platinum spark plugs can be replaced after 60000 kilometers of use. It is recommended that everyone replace spark plugs with better quality ones. These spark plugs have a lower failure rate and longer usage time. How often do people replace their spark plugs?
