When I was on the freeway,my engine started making a clicking noise. I pulled over and checked my oil and it was empty. I called the shop that does my oil change and told them that its their falt because they probebly did'nt put enough or there was a leak somewere. I had synthetic oil and was only at 3700 miles. They said its good up to 5000. Anywayz they denied everything and my car is at the dealership being checked. Does anyone here think that I have a case against the shop? My car is out of warrenty and if i have to buy another engine, should I buy a replacment or a used gts engine? Has anyone put a gts engine in a gt?
