1999 Mercedes Benz SL500 Automatic 60,000 miles I always have my car parked inside my garage. I went out of town for 4 days and when I return my car had just begun to leak oil on the night that I returned. I had not been driven for 2 months. Why would a car that has not been driven for 2 months leak oil. By the next day all of the oil had leaked out. Could there be a possibility of car tampering.
Check the sump plug is installed and tight, re fill oil and clean engine and run up, check for any leak from under car, if sump plug is tight there may be a crack in the sump, a leaking oil cooler, if leak is not visible or just a drip, have you mechanic inspect for the problem.
