I was just wondering at what mileage did you do your first oil change?  It used to be on a new vehicle, manufactures would want you to change oil after the first 500 - 1000 miles.  The belief was that's where the initial wear, metal shavings, etc. would occur during a break-in period of a new vehicle.  My wife has about 700 miles on her new Edge. I'm going to change the oil & filter at 1000 miles.  I will be switching to a full synthetic oil such as Mobil 1 , then just do my regular changes at 7,500 and so on.  I used to change my conventional oil every 3,000 miles but with the price of oil/gas I changed to 5000 miles. Now I believe switching to a full synthetic and going with the recommended 7,500 mile change I will save money and be giving my vehicle the best protection. Any thoughts?
