I agree. Think I'll have him put it in writing.

In a nutshell, here's what went wrong when my wife brought the car in for its second oil change today:
1) They said I had the wrong filter.
2) They said I need to use Mopar filters or else.
3) After getting a Mopar filter, they "forgot" that my wife had specified to use the Mobil 1 Synthoil we were supplying them. They put dino oil in and said it's okay to switch back and forth.
4) At least they didn't charge us for all this.

I know that going from synth to dino is not good for the seals (checked this with an independent ASE mechanic), so I had her call back and after some convincing the dealer will take the car back in tomorrow to put the Mobil 1 I bought in.

I've checked 6 ways to Sunday, and according to my cross references the Motorcraft FL400S - A Purolator - is the right filter for my GT Turbo. It certainly was when they put one on during the FIRST oil change (this is the second change, and should have been the second with Mobil 1). L20195 is the Purolator number cross referenced to it. I based my choice on a couple of different articles on the web including the famous Oil Filter Study.

If you ask me, they took advantage of my wife because she isn't as car savvy as I am (and probably because she's a woman).
