The service manager of a local Jag dealership told me that 10k is way too long. The factory has to pay local dealerships for the "free maintenance". By scheduling oil changes every 10k they are saving themselves millions of dollars and setting themselves up for you to buy OEM parts in the future when the warranty is long over. Be smart...every 5k minimum. Oh and how possibly could they void a warranty for extra care of a vehicle. See ya.
