^^^^ Why reinvent THE WHEEL... if dont hve to??? $4 for a pretty big bottle @ WM, cheap insurance... in gas on old Goldwing to keep the ol' girl going as long as possible, rest of my riding days and hopefully next persons days, if they treat the ol' girl well. dont overfill HORIZONTAL MOTORS!!!!!! (sigh) changing oil at night, in the dark... on a slightly sloped driveway.
