Your dealer would be the best place to ask this question. The last thing you want to do, is void your warranty. That being said, brake in oil is a high zink oil. This oil is used for the first 1000 miles about, for a new or reman. engine build. The zink oil allows the rings, bearings, and cam or cams to set. Synthetic oil, is not brake in oil, and will not let the parts ware so they can set into place as they need to. All the auto manufactures do a pre brake in before they ship a new vehicle. The engines are run on a test stand and the fluids are changed before they installe the engine. If the owners manual says your oil changes are 10,000 miles, then I am sure you have full synthetic oil. Unless you are driving under dusty conditions, there is no reason to do oil changes early. Again, I can not stress enough, talk to your dealer about all of this.
