How many liters of transmission oil should be added to the BMW X3?
2 Answers
The BMW X3 requires 6 liters of transmission oil. The functions of transmission oil are: 1. Keeping the gear system clean; 2. Extending the lifespan of the transmission device; 3. Resisting low temperatures, ensuring effective lubrication in cold conditions; 4. Reducing oil loss under harsh operating conditions. The BMW X3 is a mid-size 5-door, 5-seat SUV with body dimensions of 4717mm in length, 1891mm in width, 1689mm in height, and a wheelbase of 2864mm. It is equipped with a 2.0T engine and an 8-speed automatic transmission, delivering a maximum power of 135 kW and a maximum torque of 290 Nm.
When I bought the BMW X3 and drove it for a few years, I went to replace the transmission fluid. The technician said it usually requires about 6-8 liters, with common automatic transmission models possibly needing just 7 liters. However, this depends on the car's year and drivetrain type—newer or high-performance versions may require slightly less or more. Remember not to add fluid arbitrarily; too little oil can lead to insufficient lubrication and gear wear, while too much may cause leaks or overheating. I recommend first checking the owner's manual to confirm the exact specifications. Generally, it's advisable to inspect the transmission fluid every 60,000 kilometers or so to avoid mid-drive failures that could compromise safety. If doing it yourself, prepare a measuring cup and the appropriate fluid, but it's best to leave it to professionals since cars aren't toys. Also, some modified X3 models may have altered fluid requirements, so it's wise to leave some margin and test the fluid level for peace of mind.
