Synthetic or Mineral

Ok.... I know this oil question has been beat with a dead horse, but I just read an article regarding clutch wear specifically on the YZ when using Synthetic oil!!! There seems to be a lot of people using Amsoil with good luck and as far as I know its a synthetic oil....

Are there issues with the 08-09 running synthetic oil?

MX Action had it in the ask the experts... lol

Thanks for the link Gray. Switching brands after 7 years brings up lots o questions. The oil system on the Honda was very simple. Gear oil in trans, Amsoil in the engine...
