My car started knocking as I drove and knowing an oil change was needed soon, I went to get an oil change and was told there was barely any oil left. Performed the oil change and on the drive home on the highway my was still knocking then lost power as I drove. My car was incredibly loud, jerking as it drove, and wouldn't pass 30 mph. I was able to bring it back home though. Next day had the same guys check the car and they told me the head gasket blew. They also attempted another oil change but they said the damage was done and my car was not drivable. Insurance and the people I purchased the car from could not help stating it was normal wear and tear. I've only h0ad the car for about a year though.
