Of course, it's not JUST CTC that can screw things up BIG TIME There was another thread on here about Firestone service centers.
I have had bad experiences with others as well. Once upon a time, I was heading to the cabin at the lake, pulling the boat behind my '68 390 Mustang, and it occurred to me that I was due for an oil change. So, idiot that I am, I stopped at a gas station (I SAID it was a long time ago!) and got them to do it. Long story short, when I slowed down to make the turn up the road to the cabin, I could hear my lifters clattering. Pulled over - NOTHING on the dipstick! They had stripped the pan drain bolt and oil was dripping out.
