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?

I changed mine at 1300 miles and used the Motorcraft blend for break-in. Again at 4500 with full Syn. Can't find the Motorcraft full syn so I will be using the Kendall GT, same oil $4.27 Qt. to my door. Like $21.35 per 5 quarts. Switched to Ford 400s filter.

I think with the 2.24 Hp per C.I. stress on my engine (MP-215) and my desire to keep it for a long time I will do 5000 mile oil changes. I don't think most people understand that a 350 C.I. engine would put out 784 Hp if tuned to the stage our engines are. That is potent, the Dodge Hellcat is only 1.91 Hp per C.I...........So I will drive it like a fool when I can and pamper her with good maintenance all the time.

I think you will find high quality Synthetic oil for under $20 per 5 QT jug. Buy your oil and filter at wally world and they will change it for $10! So $35 for a full Syn and filter.....pretty cheap. But all in all I am sure the Motorcraft blend is a fine oil.
