I need your opinions if it is OK to start using synthetic oil at 4500 miles in my FZ6. I heard synthetic oil should not be used until the engine turns 10000 bikes, unless the bike has always uses synthetic oil since new as recommended by the owner's manual. The same question applies to my Honda magna and Kawi ninja 650R. I appreciate if any of you give me your inputs. Thanks.
