I bought my 03 R1 with 3000 km on the ODO. I whent to th edealer for oil change and he said R1 owners use Yamalube EFERO an jaso MA rated oil from Japan. The oil comes in a metal container with Japanese only text. The dealer sells the regular Yamalube in plastic bottles but claims the EFERO is superior.

Has any of you guys used that oil. Is it a mineral based or a synt blend? Any ratings / reviews?:confused:

never heard of it before.
