In other words, after the car is turned off, although the hydraulic system no longer maintains pressure, the hydraulic fluid in the system may continue to leak due to gravity or residual oil pressure. In particular, power steering fluid is more likely to leak in the following situations: 1. There is a small leak in the system 2. Leakage caused by pressure release 3. The influence of parking posture:

Some reports indicate that in the case of severe leaks, if the owner checks the fluid level before starting the vehicle and replenishes the fluid in time, the vehicle can be driven for about 400 miles. However, this practice is only a temporary measure and is not a long-term solution.

Many car owners may find that power steering fluid leaks are particularly noticeable when the vehicle is stopped. This phenomenon can usually be attributed to several reasons: pressure release from the hydraulic system, material shrinkage due to temperature changes, gravity, and leakage of residual liquid.
