This may sound abit weird, but I recently started to use Yamaha rotar oil on my 2155 and it works very well and stays on the pistons for quite awhile. I also used to use Al Cass (fast)valve oil and needed to oil my pistons every day and the action was slow. If I were you I would try the Yamaha rotar oil, it worked well for my Meinl Weston 2155.
