For cars that are not driven often, the replacement time of spark plugs also varies depending on the model, the environment in which it is used, and the individual's driving habits. In general, it is recommended to travel about 1 per trip60,000 to 20,000 km, or replace the spark plugs every 1 to 2 years.
First of all, the use of the car is one of the important considerations. If the car is not driven frequently and is often used for short distances, then the spark plugs may wear out faster. Short distances prevent the engine from heating up sufficiently, and incomplete combustion oil can build up on the spark plugs, affecting their performance. In this case, it is advisable to check and replace the spark plug more frequently.
Secondly, the storage environment will also have an impact on the life of the spark plug. If the car is stored in a humid or dusty environment for a long time, the spark plugs may be corroded or contaminated. In such cases, it is necessary to replace the spark plug earlier.
In addition, paying attention to the performance of the car is also an important basis for judging whether the spark plug needs to be replaced. If the engine has difficulty starting, has unstable idling, has reduced fuel economy, or has problems such as shaking and misfire, it can be a sign of aging or damage to the spark plug. Timely inspection and replacement of spark plugs can improve the operation and combustion efficiency of the engine.
Finally, it is advisable to choose the original manufacturer or premium brand spark plug suitable for the model when replacing the spark plug, and make sure that it is installed and adjusted according to the manufacturer's recommendations and requirements. If you are unsure whether the spark plug needs to be replaced, it is best to consult a professional car repair technician or go to a professional car repair shop for inspection and replacement.
In general, the spark plug replacement time for cars that are not driven often is generally 160,000 to 20,000 kilometers or about 1 to 2 years. However, depending on factors such as the use of the car, the storage environment, and the performance of the car, it may need to be replaced early. Regularly check the condition of the spark plug and replace it in time to ensure the normal operation of the engine and improve the combustion efficiency.
