My engine oil started leaking from the driver side...plus it makes my car too slow to pick up gas....im so dissappointed with mercedes cars...:( ....most of mechanics cant find the problems with my car....
Oil leaking from inspection plates on the front of engine. A technician indicated that it may be a rear main seal oil leak, which seems premature for a car with only 48,000 miles. My engine light is now on, hence I will call the dealership.
