-- I recently bought new grease for the Allegro, and last weekend I found a grease gun of my fathers to put it in, which meant removing the old Pennzoil grease cartridge. There was only about 2" of grease left, but it was the consistency of modeling clay, it was quite a pain to clean up. Seems it was pretty much ALL thickener and NO oil...Have NO idea how old it was, but 15 or 20 years isn't out of the question!
