When I bought the diesel, I got a lifetime oil change package through the dealer, and they'll do 4 changes a year based on doing an oil change every 3000 miles and driving 12000 miles a year.
The diesel spec oil is synthetic, so I plan on changing every 5000 miles, which will be about 4 changes a year at the rate I'm putting miles on the Jeep right now.
