how often do you change oil?

I change oil and filter every 6 months. It usually works out to 5k-7k miles. Call me progressive, but changing your oil every 3k miles is a waste of time imo, especially with synth oil that doesn't break down as fast as dino oil.

If your car is getting a steady diet of trips longer than 1/2 hour and getting a fair amount of highway miles, then extending your OCIs with a good synthetic oil is fine. If your car gets primarily short trips, spends a lot of time idling, or only gets 3000 miles a year, then you are better off shortening up your OCI.
I'm using Amsoil 0W-30 with mostly highway miles and I went 24,000 miles on my last oil change. This time, I'm going to 30,000 miles. My last UOA shows that my oil is still in great shape (I'm using a bypass filter, so extending my OCIs this much isn't as extreme as it seems).
