My power steering is weak. It requires too much force to turn either direction. Also the PS pump has always whined like a mother. Even when it was brand new. I took it back to the dealer and was told it's normal. I even tried another GP on the lot. It had the same whine. I have heard that running some Marvel Mystery Oil in it will improve it. I have also read on here about better fluids to use, one specifically that quiets the pump. Can somebody recommend a fluid that quiets the pump and improves the power assist? Thanks
