the dealership i talked to said it was a good idea to wait until 3k to change and let everything break in on the same fluid. who knows if they have any idea what their talking about. regardless you shouldn't have any problems.
I was using M1 synthetic for a while and was going through it ever so slightly. After I got reflashed, I started going through it kinda quick, so I switched back to dino and have been fine ever since. Now I just use Castrol GTX 5W-30
