Hey fellow bikers,

I just bought a 2007 M50 with 2K miles on it. The previous owner claims he has put synthetic oil in the bike so when I go to change it now I get mixed reviews from the dealers. Some say I have to stay synthetic, some say I can go back to regular oil, some say the bike shouldn't have synthetic with such low miles and the engine wouldn't have even broken in yet. I am totally confused now. Any thoughts would really help.

Thanks
