So I had purchased the ESP along with the car. The brake replacement and install alone will cover the cost in the long-run, so I figured why not. Of course, part of the ESP is the oil changes. So at 2300 miles, confident everything had seated properly, I took it in to swap the conventional with full synthetic. Come to find out that my ESP only had the synthetic blend option and the tech came to notify me (thankfully). The finance manager and I had discussed it and I gave him the go ahead to add it on. He wasn't there when I took it in and the other finance managers, understandably, couldn't just fix it for me. So I took the car back home, not wanting synthetic blend in the car. Now, a simple oil change is no big deal in the grand scheme of things. I can do it myself, but if I've already paid for it, why not have it done for me? Would it have been too much of a burden for the techs to have taken care of it this time, putting in full synthetic, until I got it straightened out with my finance manager? I mean, the difference in cost for them between synthetic blend and full synthetic isn't significant, and they all agreed that the oil in the 5.0 should be full synthetic. The techs and the staff were all courteous and understanding, and its not like they were trying to pull one over on me, but did I expect too much in thinking Ford would try a little harder to take care of a Mustang owner? tl;dr kinda just venting over arguably the biggest no-big-deal complaint in history.
