How many kilometers should the transmission oil of the new Jetta be changed?

1 Answers

The official user manual of the Volkswagen New Jetta recommends changing the transmission oil at 6,000 kilometers, 52,000 kilometers, and 100,000 kilometers. After that, it should be replaced every 50,000 kilometers or every three years, whichever comes first. Below are the potential hazards of not changing the transmission oil for a long time: 1. Deterioration and volatilization under high-speed and high-temperature conditions: Prolonged operation under high-speed and high temperatures can cause the transmission oil to deteriorate and volatilize, thereby accelerating the wear of mechanical components and, in severe cases, damaging internal transmission parts. 2. Difficulty in starting when the car is cold: If the transmission oil is not changed for a long time, the car may experience difficulty in starting when cold. 3. Thickening of transmission oil, which can block the transmission cooler: This can lead to overheating of the transmission oil, exacerbating wear. 4. Slight slipping during driving: Failing to change the transmission oil on time may cause slight slipping and other similar phenomena during vehicle operation.
