There ate two ways to fix this problem, but first there is the matter of understanding what is leaking. The oil you see leaking is actually a food safe vegetable based gear grease. The grease separates during heavy use (years of service) or when the mixer has not been used for an extended period of time. (months or years) The recommended way to fix the problem is to do a full tear down then clean then add new grease and a new gasket, cost (By Kitchenaid at a KA service center) around $140.00 US + or -, It involves shipping and around ten days in time. The second way is kinda simple and does not cost anything. Get a towel, thick and soft to protect your finish, get your wife or husband, get an extension cord, spread the towel out on an open counter top, plug the extension cord into the outlet, turn the mixer upside down on the towel, have your significant other hold the mixer by the base while you plug the mixer cord into the extension cord, turn on the mixer no more than 2 or the second click on the speed control switch / lever, hold the mixer upside down like this while the mixer is running and keep it running for at least three (3) minutes, turn the mixer off and turn it right side up and turn on again for two minutes, then do it again two or three more times, upside down for a couple minutes then back right side up and so on and so on, after about 15 minutes stop. put everything away, you are done. What you have effectively done is re-mix the grease and it should be good for another couple of years. When it starts to leak again re-mix again. Or send it to KA for the rare and unique opportunity to spend a hundred bucks that you don't' want. hope this helps. By the way if you get some drops in your mix it will not hurt anybody. But you do not want to eat a great deal of it or you will require the use of a laxative afterwards.
