I wonder if that isn't part of his problem. Hmmmm....running really, really
lean would give you good mileage but wouldn't that cause excessive heat
buildup? What do you think, folks? Did you let your dealer know what kind
of mileage you're getting? If you are getting 33% better than normal and
you have 3.92 gears on top of that it certainly seems mighty odd.

That's great mileage. I think the 4.7 is est. to get
21mpg & you're getting 33% more with a 3.92
Did you do anything to improve the mileage?
