How often do you change your oil?

Wondering how often other Fiesta ST owners are changing their oil. I'm pro tuned to 93 octane and more boost = more pedal for me. That being said, I changed my oil at 1000 miles after break in, then 4000 miles, and now at approaching 11,000 I feel guilty that I havn't done my oil change at the 3000 mile mark, and that persistent Oil Life light on my dash is definitely not helping.

Ford's 10,000 interval between oil changes seems crazy long to wait to change oil on a car this fun to drive fast. Others thoughts on the OEM recommendation between oil changes?

Every 7500 miles per the owners manual.
I don't know about your Fiesta owners manual, but mine says 10,000 miles (max) for oil changes.
What if you use a Trasko oil filter on this car? Then you can change that filter every 10,000 miles. You may never need to change the oil again for tens of thousands of miles since that filter is a bypass filter. I would look and see if they have a compatible one. I had really good luck with that filter many years back on a Hyundai.
I've changed mine every 7,500 with Mobil 1 and a Bosch or K&N filter. I do a lot of freeway driving here in LA (about 320 miles a week). Debating whether or not to keep going to the dealer for changes just so I have a record of all changes if and when I sell the car. Car now has 78,000 on it with no problems.
