I don't know if motul is as good as Amsoil but after my last oil change, I don't care. I had let the oil change go for a little over 5000 miles before I changed the oil. When I did, the old oil still had some gold color to it. Granted, this was the first time I had used the Amsoil 20/50 in my bike. I had been using 10-40. I just put 10-40 in her this change but may go back to 20-50. I will let you know.
