Andrew has posted a good reply. If you take care of the engine: change the oil, put good fuel in it, and replace the glow plugs if they are bad, and keep the cooling system in good shape(hmm, sounds llike what you would do with any engine, except the low plugs) it will be a long lasting engine that is predictable, easy to maintain andreturns good fuel milage.
My 6.2 has 74,000 miles on it. It is in a 6700lb, 1990 suburban with 39.5' bias ply Iroks and a 1 ton drivetrain with 5.13 gears(it does have OD). I pull 15 miles per gallon consistantly. My big block powered truck that weighed a little more than the sub only got 7-9 mpg and most any small block in my truck would maybe get 12 mpg.
Botom line: If you want a good running engine that gives good mileage, the 6.2 is it.
