Engine Performance problem
2007 Nissan Sentra 4 cyl Four Wheel Drive Automatic 41,000 miles
My car has an oil leak. I recently (3 weeks ago) had an oil change because my oil was registering low and the engine was shaky. I brought it to my dealer (right after the oil change), and they said I did not have a leak. Obviously they were wrong as my oil is low again. Is this an easy mistake for them to make? Or would there be a reason for them not correcting it?
