I've been changing the oil and filter on my R80RT for a number of years but there seems to be a change in the newest oil filter. The bike calls for the hinged filter - no problem. The filter can go in either end first. This time, however, the new filter has the normal black rubber on one end, but the other end is just the aluminum end with hole -- no black rubber like the past filters. The one I am taking out as all the previous ones have the black rubber of both ends of the filter.

Has there been a change in filters? The part number is the same on the old and new filters.
