i think you should change oil every 5000 to 7500 miles.the factory interval of up to 15000 miles is too long imo,and that of many mechanics i have talked to.i plan to keep my car a long time.an extra oil change is expensive for what it is,but it's cheap insurance and peace of mind for this very high performance engine.there is a proviso in the factory maintenance for changing it after a year,which got me a free oil change after about 7500 miles even though the computer was indicating later.
