Again personally I would fill it with Mobil 1 synthetic 75w90 grade I think it is and not worry. Perhaps also if your dealer contacts Honda maybe they have this special juice they put in at the factory fill. Just this past month a friend I ride with took his GL1800 in for a rear tire and his GL had 11k on it and he ask them to check his oil level and they like your dealer said "it was nasty looking so we drained it and refilled" IMHO I can't believe that draining the rear end premature will result in complete rear end failure.
