Marvel Mystery Oil
I met a fellow rider, in Sky Londa,
who was very opinionated and had a burning need to tell me about the
various vagaries of motorcycle oils and additives. He is a firm
believer in the benefits of using Marvel Mystery Oil. I decided to give it a try, as I was beginning to have trouble starting my Volusia after it had sat idle for a week or two. I have to admit that my bike starts easier now. I add about a ¼ ounce of MMO
to a full tank of gas. My crankcase appears clean, so I haven't put any
in the crankcase oil. If it does what is claimed it does, I'll continue
to use this mysterious stuff.
