I had an issue two oil changes ago with the Mobil filter. For some reason, it didn't stay on as tight as it should have, and as a result, was leaking. I did some research and found NO where does Mobil suggest using the M1-209 with the PT Cruiser. (I'm not sure if it recommends the filter for the SRT?) So, I went with the K&N HP2900, which is designed for the PT. I haven't had any problems with it. (Same price roughly as the Mobil filter.)
