I am new to the forum(first post. I have a 01 Vstar that it's time to change the oil. I asked my wife to pick me up some oil. Well Wal-mart was out of Mobil 1 15w40. So she pick me up some Rotella syn 5w-40. What is the story on this oil? Would it work fine in my bike? I can always use it on my tractor if it is not good for the bike. But I just hate to drive 60miles to get it. Tell me what you think...
