Engines can be divided into two types based on the fuel used: gasoline and diesel. Gasoline engines have a different ignition method than diesel engines, which requires the use of spark plugs. The importance of spark plugs for engines or vehicles is self-evident, as they are vulnerable parts that require replacement cycles. Many car owners have certain misconceptions about this point when using a car. Today, let's talk about some knowledge about spark plugs.

Spark plugs have different usage times depending on the electrode material. There are many types of corresponding materials on the market now. Ordinary spark plugs generally have a mileage of about 20000 to 30000 kilometers, platinum plugs can be increased to 40000 to 50000 kilometers, iridium plugs can reach about 80000 kilometers, and there are also double platinum, iridium platinum, and so on. The corresponding usage mileage is also different. In fact, it is not necessary to remember in detail. In short, the more expensive it is, the longer it will be used. However, it should be noted that this mileage is the most economical or recommended mileage to use. Nowadays, most spark plugs have relatively good quality, and it is normal to use them again beyond the marked mileage. However, whether to continue using them or not needs to be fully considered.

The ignition effect of spark plugs will decrease during use. Simply put, the electric spark will become smaller and smaller. It is normal for many ordinary spark plugs to be used for 40000 to 50000 kilometers without any faults, and sometimes even more. However, after exceeding the recommended mileage, the ignition effect will decrease, which will cause insufficient fuel combustion, increase fuel consumption, accumulate carbon, and reduce power. Although it may not feel very obvious, it is not beneficial for the engine. Spark plugs are not expensive compared to the mileage used. Therefore, it is recommended to replace them after reaching the mileage. The specific amount is stated in the manual, and it is also okay to replace them later. Of course, if they break down early, they need to be replaced in a timely manner. The sentence is:.

After the spark plug malfunctions, the engine generally idles very unstably, sometimes even jumping up and down and stalling. While the power decreases, the fuel consumption increases significantly. As for how to choose a new spark plug, it basically depends on the money. As mentioned above, choosing the more expensive one is better. It not only has a longer mileage, but also has better ignition effect, which can slightly improve power and reduce fuel consumption.
