Hello, I have been noticing a small puddle of blue (oily) fluid on the garage floor under the front of our mini s conv. 2006. I can tell you what its not..... brake fluid, windshield washer fluid, engine oil, antifreeze. Any one have any idea? THanks!

 

I will bet it's coolant leaking from the thermostat housing. Happens all the time and the stock coolant is blue.

 

I think is coolant fluid.. keep it away from dogs, coolant is like candy for them.
