If the spark plug is not replaced for 200,000 kilometers, what is the impact of not replacing the spark plug?

Although the manufacturer recommends replacing the spark plugs every 30,000 to 50,000 kilometers, the spark plugs are actually more powerful than we thought. Usually, it is not too late to replace 80,000 to 100,000 kilometers. However, the spark plug should not be replaced for too long. There was once a car owner who did not replace the spark plug for 200,000 kilometers, which caused serious carbon deposits in the engine and needed to be dismantled and overhauled.

What effect will the spark plug not change?

After the spark plug is used for a long time, its ignition efficiency will continue to decline, which will result in the combustible mixture being unable to be ignited and burned under the most ideal conditions, resulting in increased fuel consumption and lack of power.There may also be difficulty in starting, engine jitter, increased carbon deposits, threeYuanCatalytic converter damage, exhaust emissions not up to standard, etc., can even lead to engine failures that require disassembly and repair.

Although the spark plug can be replaced only once for almost 100,000 kilometers, the use of the spark plug should be checked every major maintenance. There are roughly three points in the inspection of the use of spark plugs:

1,Check whether the metal head on the top of the spark plug is ablated or deformed;

2,Check whether the ceramic insulator has yellowish-brown patches, which is a manifestation of the leakage of the insulator;

3.Check the carbon deposit on the electrode of the spark plug, the edge and the gap of the electrode.
