I went to get an oil change at Valvoline Instant Oil change. Everything seemed fine when I left, the car drove fine, I park it at home in the garage. My wife takes it to work the next morning, and on the way, calls me to ask me about the oil light being on. I told her I just got the oil changed yesterday. To make a long story short, the engine locked up and several mechanics (including Valvoline) say it was their fault because the wrong filter was put on. They want to put in a used engine (which I agreed to) but they want to take it to one of their mechanics and I trust the dealership for a job this big. They don't want to pay to have the dealership do it. Do I have a case? I just don't trust "their people" to install an engine. I'd much rather have the dealership do this and they should pay since they messed up my truck.
