I do mine about every 5K miles. But it all depends on my mood and if I am around the dealership. It is my daily driver but I don't put a lot of miles on the car. If I feel like it has been a while and I am less than 5K miles, I will just get it done.

I put less than 4K miles on my car since the last oil change in the fall. I could wait but it has been a while. I think I will bring it in soon before it gets too hot down here!
