I'm thinking about switching over to this new oil, Mobil 1 Extended Performance 5W-30 (synthetic oil), which the company guarantees for 15k miles or 1 year. My car is not driven rough, just the normal mostly highway commute back and forth, usually less than 15k miles per year.

What about the oil filter? Obviously a "normal" oil filter probably won't last anywhere near 15k miles. Mobile 1 has an oil filter that goes along with this oil, Mobil 1 Extended Performance Oil Filter. Anyone use the K&N Performance Gold Oil Filter? I'm deciding whether to get the Mobile 1 filter or go with the K&N filter, what do you guys think?
