How many kilometers should the transmission oil of the new Jetta be changed?
2 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.
I've been driving my new Jetta for almost ten years now, and I'm quite familiar with the transmission oil situation. Generally, manufacturers recommend changing the automatic transmission oil every 60,000 kilometers. But based on my practical experience, it also depends on your driving habits—if you're constantly stuck in city traffic or frequently drive uphill, you might need to change it as early as 50,000 kilometers. The oil acts like the car's lubricant; when it gets old, it can cause rough shifting and accelerate wear on parts. Once, I delayed changing it until 70,000 kilometers, and the transmission started making strange noises. I had to rush to get it fixed, costing me an extra thousand bucks. To be safe, I stick to changing the oil every 60,000 kilometers while also checking if the oil is clear or cloudy. I always use the manufacturer-recommended oil to avoid mixing issues. Regular maintenance keeps the car running smoothly and longer, saving both hassle and money.
