Good morning guys. the oil was changed in my friends 560SEL at the mb independent's shop. He topped the power steering off with red fluid. The pum has also been whining ever since....a pretty loud whine. Was this the wrong fluid or just some coincidence. My owners manual says only mb fluid which is clear.Any inpt. Second time posting it by the way and I can't believe nobody has any input so heres a second chance to help a guy out. Thanks one and all
