There is no fixed standard for the service life of the oil seal. Generally speaking, the oil seal on the transmission shaft of the automobile transmission can guarantee 200,000 to 300,000 kilometers without oil leakage under normal circumstances, and can be used for more than ten years under ideal conditions.
But in fact, the service life of the oil seal is related to many factors. For example, driving habits. If you frequently brake and accelerate suddenly during driving, it will cause greater wear on the oil seal and shorten its service life. Another example is the car environment. If you often drive on bad road conditions, the oil seal is also easily damaged.
It is usually common to replace the oil seal every 20,000 to 30,000 kilometers or 8 to 12 months in daily life. However, there are special cases. Some oil seals may have problems in 1 month, and some may need to be replaced in 3 to 5 months.
To extend the service life of the oil seal, you must maintain good driving habits and regularly maintain the vehicle. Due to the influence of driving habits and environmental factors, its life may vary.
