New vehicle engine oil- first oil change recommendations

There's no science for changing the oil early, however.....
I do the 500 mile oil and filter change for two unsubstantiated reasons. 1) To eliminate any contamination from the manufacturing process that may have been inadvertently left in the engine. 2) To remove any small particles the initial operation of the engine may produce that are too small for the oil filter to remove, expecting their presence will decrease to normal levels rapidly.
