Query: Disappointed with KitchenAid 4 1/2 Quart Mixer

Started using mixer in 2002...in Dec. 2004 had to take it in for service...all the oil had leaked out. Was told I didn't use it enough! Nearest authorized service center is 35 miles away. I threw away a 30 year old GE mixer when I purchased this one...wish I had it back. (I must now order a new cover since the old one is stained on four sides by oil.)
