Sky, since your vehicle is a late model built to tighter specifications I would go with the lightest weight that still gives decent oil pressure at operating temperature during idle. The lighter oil will flow quicker and, therefore, give faster protection during cold start up. As the bearing surfaces wear with mileage and you experience some loss of pressure with the passing years at operating temperatures you can then go to a thicker weight. I am not a mechanic and I did not even spend last night in a Holiday Inn Express but I have had good experience with engines of all types in all sorts of vehicles through the years. (oh yeah, I have read enough articles pertaining to lubrication of my boats, airplanes and sports cars to get atleast an associate's degree).
