Thanks for responding to my post! I do understand that the schedule 2 maintenance states to do an oil change at 7,500 mi or 6 mon whichever comes first, but I drive alot so I think that I should not go that far between changes. And on the other hand the schedule 1 maintenance states to change the oil at 3,750 mi or 3 mon whichever comes first, so I was thinking I would just fall somewhere in between those. I drive my car hard, but not too hard, and I rack up those miles quick. I will check the color of my oil at 5,000 mi and see if it is going to need to be changed at that point, I may try to push it to 6 or 7k. Thanks for all of your input!
