I took my bike to a mechanic who is considered widely to be THE guy when it comes to my particular bike brand. I asked him what he thought about the Torco my dealer uses and the M1 V twin i just started using. In no uncertain terms he told me to use Motul 5100. he mentioned it will shift better with it. Thinking about what he said it occurred to me that maybe he didn't so much mean that it's better oil than what i'm using, but just that it sifts better. And to me that doesn't matter because mine shifts 100% fine as is. So i don't know if he also meant it's the best oil to use overall, but he did say thats what most of his customers prefer and all he uses. What are your opinions on this oil? I hear a lot more about amsoil amd M1 bike oils than i do motul. Is this some sort of "insiders" oil or what?
