After a hilly ride though the poconos Pa. my 06 S auto left a 6" spot of oil in the garage? It hasnt done it after that, Yet. Checked the oil its full but the spot puzzles me. anyone have tis before? Does it have something to do with the supercharger?

 

Possibly the motor mount leaking? You can search the forums for threads on this - many folks have posted pictures. The mount is on the passenger side between the engine and the shock tower. It is a silverish can.

 

it could be your power steering fluid. or is it definately oil? since yo usaid your oil wasnt low

 

Hope it isn't anything serious. Is your MINI under warrenty?
