My car's reducing PS oil. Every time I fill in, there's lot of it leaked and accumulated underneath the car. The whole bottle gets emptied in 3-4 days.
After that, it produces whinning sound. After few days, steering becomes harder and whinning sound gone.
If I insert another bottle at this point, the cycle repeats.
Which could be possible cause? Have visited 3-4 mechanics and replaced two pipes. Still not fixed
