2006 R350 oil level message came on. My husband added oil then check engine message appeared. Then my car started sounding like the engine wasn't running on all cylinders, i.e., running rough!
My car only has 58k miles it's been great so far. It was driving perfectly until my husband
put the oil in it. I've no idea why he felt it necessary to add it @10:30pm on our way home
at the gas station. He said the lighting was terrible.
