Got a customer getting about 16 out of his new dually. Just spoke with him today. Might have something to do with using a 35K lb backhoe to beak it in, though . . . . :rof

I was getting 11MPG, took the lid off my factory air box and now get 13MPG!!

I have 20" wheels and 33" mud tires though...I hear they KILL fuel milage! Also have a straight pipe in place of the muffler.

I assume you've adjusted the mileage for the larger tires.

I have an '06 LBZ, and I'm getting about 16 mpg, mostly city driving. Only have 600 miles on it. Can't believe it has to go into the shop already! :mad:

I have an 07' Classic and I got 15.4 out of the first tank I ran through it. I thought that was pretty good considering the amount of pedal to the floor driving that was done :thumbsup

Had a bunch of little stuff wrong with it, the biggest of which was an awfully loud belt chirp that happens until warm up. The others were little things in the dash board making noises. It seems like the dealership here near san clemente is pretty good, they already found one thing wrong with one of the A/C dampners that was making a loud thud. Anyway, we will see if they find and fix everything tomorrow. They have only had it one afternoon.
