Nowadays, many automatic gears are advertised under the slogan of maintenance-free. Is that really the case? No matter at or CVT gearbox, its gearbox oil can not be truly maintenance-free. The maintenance-free promoted by the manufacturer is only the test conclusion under theoretical conditions or simulated road conditions. Everyone's driving habits are different. Some people regard cars as treasures, others regard them as cows, and the loads in their gearboxes are different.

Any petroleum product has a service life. In the process of long-term use, the lubrication system of transmission oil will be reduced, which will affect the sealing performance of hydraulic components in CVT transmission and accelerate the wear between steel belt and pulley of CVT transmission. This effect is not immediate, but accumulated bit by bit in daily use. When you find that the uphill power transmission is insufficient, it is estimated to be 7-8 years later or about 300,000 kilometers.

It depends on the way you drive.

Therefore, CVT oil change or not has a lot to do with personal driving style. Frequent violent driving, big foot throttle, big foot brake, then the gearbox is too worn, resulting in a lot of impurities, and the sense of frustration will be strengthened. After changing clean CVT oil, impurities will not be smooth.

If it's a normal driving style, you rarely drive violently, so you don't have to worry about oil quality at all. At least, it is no problem to drive to 654.38+ 10,000 kilometers.

Therefore, everyone should judge their own driving style and then decide whether to change CVT transmission oil.

Channels of oil products and oil changing methods

In addition, there is another saying, but it has not been confirmed (only for Nissan models).

When the original car leaves the factory, there is a certain gap in quality between the CVT oil added and the CVT oil we saw in the market, including the 4S shop, and the quality of the original car oil is better. Theoretically, there is such a problem. After all, the oil channel in the market cannot be guaranteed, even in 4S stores.

In some cases, after the owner changed CVT oil, the vehicle appeared thermal protection. In most cases, there should be a problem with the oil circuit, and the quality of the replaced oil is not as good as that of the original car!

In addition, if CVT changes oil, it is best to change oil by traditional gravity instead of circulating machine. Waste glistening money, use at least two barrels of gearbox; Secondly, the circulating machine makes the gearbox oil flow at high speed, which is easy to roll up impurities in the oil pan and spread all over the gearbox, causing greater wear and tear.

Although the CVT gearbox is simple in structure, it is still very exquisite. AT least, the gap between them is the distance between the steel belt and the gear, and the cost of later maintenance is obviously higher than that of AT gearbox. So, usually drive as lightly as possible, just? Music for the elderly? Just drive.
