After much extensive research, I am now more confused than before.

Many on rentech and other reputable sites believe that M1 xw40 is great but apparently cant be had in the states. They actually believe Mobile 1 10w30 may lead to the "AOS" failure and white smoke. Most also suggest a minimum of 7500mile changes, and less if you are hard on it. Some even suggest 2 times a year for the different seasons in ohio. Like 5W40 for winter and 15W40 for summer.

Questions:
1.)What oil do you use in your Boxster? I am in ohio so we get some cold weather. I am leaning towards Castro syntec 5W40.

2.)what air and oil filters should I use? I have heard great things about K&N.
