Over filled oil
I had the oil changed and a week later it started making a banging noise. I took it back and they had over filled the oil. One mechanic said the over filling caused engine damage. Today another man said that he did research and it was not caused by them. He will put in another motor for $2600. I am being screwed by them. The car belonged to my 91 year old mother and only has 97000 miles on it. What do you think?
