Product review (5 stars): Great for tipup Kitchen Aid mixers that set withou use or in storage
I had to repack the gear box on our Kitchen Aid Mixer due to the grease separating and a brownish mess dripping into a batch of bread dough.  The reality is you should run your mixer once a week if it is the type where the head tilts up to remove the bowl, else you will be repacking it too.  By running the mixer once a week you keep the grease incorporated inside the gearbox.  If you don't, when the grease separates inside and you tip the head up the liquid part of the grease separation will leak out the upper gear box seal and through the inside of the mixer.  Early indications are the brown drops of grease behind the mixer after the head has been tipped up for a while.  That is not from the motor, it is tracking down the mixer gearbox in the top front of the head and out the back cover.  This grease works perfect for a mixer gearbox repack.  The one thing to note, it is a lot of grease for one repack, call your Kitchen Aid friends over and do theirs too...
