I would highly recommend changing your diff fluid as well. All of those new metal parts are working themselves in and putting a lot of metal in the oil. Get it out and some fresh oil in. IMHO the most critical part of the break-in process.
I was recommended by my dealer to bring mine in at 25 hours. However, I changed my engine and gearbox oil at 10 hours myself.
But I wanted to check on what everyone thought on changing the differential oils as well, since this is not mentioned in the 10 hour service.
