I attempted to do a doughnut today in a nearby parking lot.. (i know, just trying to impress the ladies..) and i did a full doughnut and a small burnout takeoff.. after that i had no power steering. It would make a whining kind of noise if i steered left or right on takeoff.. and it would get louder when i accelerate... Checked the power steering fluid level and it was low.. so i added more. But before i added more, the fluid inside was a dark brown, almost like a balsamic vinegar. what can i do before i get a ridiculous estimate from a mechanic? Any help would be appreciated
