Source of oil leak

[brumbach]

I have a 2014 outback. I noticed oil resident inside the passenger side wheel well and running along the trim below the passenger side doors to the rear wheel well. No oil leaks are present in the engine compartment. Inspected cv boots...dry and free of tears. I called the Subaru Service Desk and they think I must've run through an oil spill somewhere. Washed the area and the oil reappeared after operating. I plan to take in to service ctr but that's 70 miles away. Will have to have it towed to avoid damaging if critical. Engine oil lever is good. Power steering level is good. Brake fluid level is good. Coolant level is good. Can't check transmission fluid (sealed unit with no dip stick). Oil is clear colored. No warning lights lit on control panel. Any idea as to where the leak may be from? Thanks in advance
