Check back through the tech forum... a while back there was a discussion concerning the same issue... some opted for 5k other decided to stay with the interval the computer in the car tells you. which is around 7k. In my case the computer was showing me I could go to 8k because of the conditions it had been driven

Personaly, I'm going with what the computer in the car says... it senses the condition of the oil.

I would never go with 3k... IMO it's only a money maker for the dealer...
