Does it matter if the transmission oil is not changed for 6 years?
In the maintenance of the car, the change of transmission oil is an important link. However, some car owners may not change the transmission oil for a long time due to various reasons, such as negligence or lack of knowledge about vehicle maintenance. So, does it matter if the transmission oil is not changed for 6 years?
First, let's take a look at the role of transmission fluid. Transmission oil is an important part of the transmission system, and its main functions include lubrication, cleaning, heat dissipation, rust prevention, etc. During the working process of the gearbox, the performance of the transmission oil will be affected by various factors, such as high temperature, oxidation, impurities, etc., which will lead to the gradual decline of the performance of the transmission oil.
Next, let's analyze the consequences of not changing the transmission oil for a long time. If the transmission oil is not changed for a long time, the impurities and contaminants in the oil will gradually accumulate, resulting in the formation of sludge, paint film, sediment, etc., which will clog the transmission filter, reduce the lubrication performance of the transmission oil, increase the friction and wear of the transmission, and even lead to damage to the internal parts of the transmission in serious cases. At the same time, transmission oil that has not been replaced for a long time may also oxidize and acidify, causing oil deterioration and corrosion of the metal parts inside the transmission.
So, how can you tell if the transmission fluid needs to be replaced?Generally speaking, the transmission fluid replacement cycle depends on a variety of factors such as the owner's driving condition, transmission type, transmission oil quality, etc. According to the usual maintenance recommendations, the transmission oil replacement interval is usually 2-60,000 kilometers or about 2-3 years. Car owners can determine the specific replacement cycle by consulting the vehicle's manual or consulting a professional maintenance professional.
In addition, car owners can also judge whether it needs to be replaced by looking at the appearance and feel of the transmission fluid. If the transmission oil is black, cloudy, sticky or has a very poor feel, it means that the oil has oxidized and deteriorated and needs to be replaced in time.
Of course, some vehicle transmission oils are maintenance-free or long-lasting, and these oils are of better quality and performance, and the replacement interval is relatively long. However, even if it is maintenance-free or long-lasting transmission fluid, the car is certified by Quality Author Recruitment
