Thanks for all the replies.
You didn't say which Mobil 1 oil or how you drive. 10,000 miles would be the stock answer for your basic Mobil 1, provided you do not hit the "severe service" definitions in your owners manual. Cut that in half if you do a lot of towing or drive in extremely dusty conditions. If in doubt you could always send out a sample for used oil analysis.
BTW - hats off to the guy who made the Gallo to French wine analogy.
