Since I put this oil in the machine it really seems that some of the noise the motor makes has dropped off some. It just seems like the motor just isn’t as loud as it used to be. I heard that RP will quieten down motors but I really did not believe it would. Maybe I was wrong and it really does. Maybe I just finally got all my rattles fixed and I just think it was the oil in the motor doing the trick. Who really knows and all I do know is my 570 is a little less noisy.
