I had my 1st KA - mothers (which I handed down to a friends daughter who is still using it) from 1950s, bought my own in 1981 (which I donated to a church group of young bakers in 2004), purchased another in 2004 -Artisan style which I sold to upgrade in 2011 to Professional 6qt which am still using. Over all these years and mixers I've never oiled, had oil/grease problems or any problem (and believe me I've made brads, wedding cakes, meats, etc) Maybe it's like Temptations but I doubt it highly KA has been around forever & of course I would recommend it!
