I would change the oil before the trip.
The main objective in initial oil changes on a new vehicle (engine) is to facilitate the removal of harmful manufacturing and break-in debris for those interested in long engine life.
Mr. Jim Fitch, founder of Noria Corp. has authored a book "How to select an Oil and Filter for your Car or Truck" The above statement is from page 43. http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=How+to+select+an+oil+and+filter+for+your+car+or+truck
Table 13 on this same page Mr. Fitch outlines his RECOMMENDATIONS for the first few oil changes: 1st oil change within 100 miles of taking possession of the vehicle; 2nd oil change 1500 miles after 1st change, 3rd oil change 3K miles after 2nd, 4th and beyond at normal intervals. Go synthetic at 4th change. His recommendations are only if you're interested in keeping your car a long time.
If you've never heard of Mr. Fitch or Noria; I would suggest a cursory google search; his credentials are quite impressive in the world of lubricants.
Jim Fitch is the CEO and a co-founder of Noria Corporation. He has a wealth of “in the trenches” experience in lubrication, oil analysis, tribology and machinery failure investigations. Over the past two decades, Jim has presented hundreds of courses on these subjects and has published more than 200 technical articles, papers and publications. He serves as a U.S. delegate to the ISO tribology and oil analysis working group, and has been awarded numerous patents. Since 2002, Jim has also been director and board member of the International Council for Machinery Lubrication. Among his specializations are motor oil and Engine Lubrication.
I mean no "slam" to anyone on this board, there are some quite knowledgeable people on here who are experts in their fields; but I would rank Mr. Fitch right up there and take his advice over most anyone on this board.
Nevertheless, it is your vehicle and you are the one who must sleep at night with your decision. It's your car; do as you please, I'm just sharing thoughts from someone I believe qualified to offer informed opinion. Hope you enjoy your new vehicle.
