Spark plug mileage also varies

Spark plugs are consumables, and the mileage of use varies depending on the material. A copper core spark plug can last about 20,000 to 30,000 kilometers, a nickel alloy spark plug can last about 40,000 to 60,000 kilometers, and a platinum spark plug can last about 80,000 kilometers. Kilometers, iridium alloy spark plugs can probably last for more than 100,000 kilometers. Of course, these data are not absolute. It also depends on the usage of the vehicle. If there is a problem, replace it as soon as possible.
Judging from the use of spark plugs, you can judge the operating status of the car. If the spark plug electrode is black and there is carbon deposit, this phenomenon may be caused by the mixture being too rich, the spark plug being too cold, burning oil, or misfiring. If the spark plug electrode is white and there is ablation, it may be caused by the mixture being too thin, the spark plug selection being overheated, the spark plug leaking, etc. Since repairs are all modular now, basically no one uses the "homespun method" of using a lighter to bake the spark plugs, or scraping off the carbon deposits with a knife. During repairs, they will directly replace them with new ones. This is a simple and clear method, but there are some The dealer will ask you to replace the spark plug with a better one. After replacing this spark plug, the acceleration will be stronger and the fuel consumption will be reduced. Please don't believe this nonsense. Just tell him that it will be better to replace it with the original one of the original car. Although it will be better. Theoretically, there will be an improvement, but not much. If you are not riding for competition, the replacement does not make much sense. If you are competing, you will definitely replace the entire ignition system. According to the material, it is true that iridium spark plugs last longer in kilometers, but the price will rise accordingly, and the distance depends on the engine operating conditions, so choose the spark plug according to your own situation. Let's talk about the calorific value selection of the spark plug. The higher the calorific value of the spark plug, the stronger the heat dissipation. If the calorific value of the original car is 7, and you are used to riding in the red zone, you can only choose a spark plug with a calorific value of 8. , no matter how high it is, it is not appropriate. Don't blindly choose a spark plug with the same calorific value as a large displacement. It will only damage your car. It is safest to choose the spark plug model specified in the manual.
