How many liters of transmission oil should be added to a BMW X1?

BMW X1 requires 8 liters of transmission oil. Transmission oil is a lubricant that maintains the cleanliness of the gear system. Its functions include: 1. Ensuring the normal operation of the transmission and extending the service life of the transmission device; 2. Providing effective lubrication at low temperatures; 3. Reducing oil loss under harsh operating conditions. The BMW X1 is a compact SUV model. Taking the 2021 BMW X1 as an example, its body dimensions are: length 4565 mm, width 1821 mm, height 1620 mm, with a wheelbase of 2780 mm, a fuel tank capacity of 61 liters, and a trunk capacity ranging from 505 to 1650 liters.
I drove a BMW X1 for several years and changed the transmission fluid a few times. I remember the fill volume was around 7 liters, but it depends on the model year and engine version. Once I did it myself—drained the old fluid and poured in new fluid—but only added 6.5 liters, which caused the transmission to jerk and nearly led to serious issues. Later, at a professional shop, they used exactly 7 liters to fix it and reminded me to use OEM-recommended fluids like ZF Lifeguard 8, never ordinary oil. Transmission fluid should be replaced every 80,000 km to maintain lubrication and cooling, preventing gear wear and major repairs. With the correct fluid level, gear shifts stay smooth, ensuring safety and peace of mind in daily driving.
When handling the BMW X1 transmission fluid replacement in the workshop, I found that in most cases, 7 to 7.5 liters are required, based on the specifications of the ZF 8-speed automatic transmission. Operationally, we first use specialized equipment to clean the residual old fluid, then slowly refill with new fluid to ensure the level is within the standard range. The key point is to use the appropriate fluid type, such as ATF Dexron VI, otherwise unstable oil pressure may damage the internal valve body. Personally, I recommend checking the fluid quality every 60,000 to 70,000 kilometers. If discoloration or unusual odor is detected, replace it promptly to avoid costly repairs. Simple DIY can be attempted, but be sure to follow the manual instructions and avoid guessing the refill quantity.
Just got a BMW X1 and was curious about how much transmission fluid to add. After checking the manual, I found out it's about 7 liters. As a newbie, I was worried about making mistakes and didn't dare to do it myself, so I consulted a professional shop recommended by a friend. The owner said the amount is roughly 7 liters, but it also depends on the specific model, whether it's an N20 or B38 engine, and the oil should be high-performance synthetic like Castrol. Regular oil changes maintain the transmission's lifespan, and I plan to service it every 50,000 km to avoid breakdowns. Through this learning process, I realized that paying attention to small details can save big troubles—safety first, after all.
