Yes and to be honest I don't pay much attention b/c its depressing. Pulling that rig it has to be around 8 maybe. Empty 13 ish. I have two 3/4ton pickups w/ 6.0 autos also that aren't much better on MPG. But it was a LOT cheaper option than the diesels (we have 3 7.3 power strokes too). It does pull nice though.
