|10k intervals for oil changes for a long time now.
Why do you think they all come with free maintenance for 60k miles so long as you let the dealership do the work?
They would never put that program in place until they reduced the cost that the dealerships would be charging back to them. They didn't just arbitrarily pick pick 10k over 3k without the necessary changes in design/engineering. That would be suicidal from a longterm business/brand standpoint
