Leaking fluid, oil I think around the kitchen aid ring

Bucksmom, Sorry to hear you mixer is 'leaking'... I hate it when that happens. You don't mention how old or what model your KA mixer is? I assume you mean the band around your mixer with the Kitchenaid logo, when you say 'kitchen aid ring.
Your mixer does have an internal gear mechanism (transmission if you will) which converts the electric motors rotation into the mixer rotation and those gears are located within the mixer. The gears were lubricated at the factory, but depending on the age of your mixer and how it is used, it is possible that the grease has leaked beyond the gasket and that is what you are seeing now.
It is possible to disassemble the mixer to determine where the grease is coming from and troubleshoot if anything else might be wrong within the transmission.
Hopefully the leakage is not getting into your food being mixed. Kitchenaid Grease should be 'food grade' grease, but you still don't want to ingest it.
I hope this helps... Howard, Burke, VA

Hiya,

Over time the grease in the mixer can get very hot and oily, the grease will then fall into the drip ring but sometimes the drip ring will need to be taken off and then cleaned. This should solve the problem.
I have added a link below for a video which shows taking the drip ring off. Please forward the video to 1:25 and this should show you the correct part of the video that will help you.
