My 570 was sold to me as new. After trailering it home, I discovered it had 39 miles on it and the break-in oil had not been changed. The dealer gave me a bunch of mumbo jumbo about how the miles might have been put on there but I am concerned about the break-in oil. When I drained it, it was a very light milky brown color (almost like light chocolate milk made with water) and the viscosity seemed like almost zero. Is this normal? Thanks is advance for any insights.
