How many liters of CVT transmission fluid does the Nissan X-Trail require?
2 Answers
For the Nissan X-Trail CVT transmission fluid, if manually changed (gravity method), it requires approximately 4 to 6 liters; if using a fluid exchange machine, it requires about 9 to 12 liters. The replacement intervals vary for different vehicle models. Below are the recommended replacement intervals for transmission fluid: Manual Transmission: Manual transmission fluid is generally recommended to be replaced every three years or approximately every 100,000 kilometers. Automatic Transmission: Automatic transmission fluid is generally recommended to be replaced every two years or approximately every 40,000 kilometers. Continuously Variable Transmission (CVT): CVT fluid is generally recommended to be replaced every two years or approximately every 60,000 kilometers. The methods for replacing transmission fluid are as follows: Unscrew the drain plug at the bottom of the transmission to drain the old fluid before refilling. Remove the transmission oil pan directly to drain and refill the fluid: This method is more thorough than the previous one, as it removes impurities from the bottom of the oil pan. Use a circulation machine to replace automatic transmission fluid: A smart circulation machine can dynamically exchange the fluid, filtering and cleaning sludge and impurities from the automatic transmission.
Last time I helped my sister change the transmission fluid for her X-Trail, I did a lot of research. This model requires NS-3 specification CVT fluid, and a gravity change typically needs about 4-5 liters. However, if you replace the filter and oil pan as well, it might take up to 6 liters. Some repair shops use a flushing machine, which is excessive—it requires pouring in 10-12 liters to thoroughly clean the system. I specifically checked the maintenance manual, and the manufacturer recommends a gravity change every 60,000 kilometers. But if you frequently drive long distances or tow heavy loads, it's safer to change it at 50,000 kilometers. When changing the fluid, make sure to watch out for counterfeit oil—poor-quality fluid can quickly ruin the steel belt.
