I have achieved,for me the all time best of 23.7 going 60mph,cruise control, no traffic stopping, all highway fuel station to fuel station, fuel additive PS&MMO, on a run vancouver to seattle, on a windless 70 F warm day, unloaded on summer fuel. The worst was pulling a 8500# 28 foot travel trailer in Northern Cal of 13.8. Dang I love my 305/555 isb!!!!!
Case in point:
Lets see a 55 chevy with a small V8 and emission levels that allowed half the fuel to go out the tailpipe, weighed 2/3rds of what our trucks do, has the aerodynamics of a sheet of plywood, accelerate well and would still get 13+ MPG. My wifes 2001 Acura MDX suv with the latest engine technology, aerodynamics and lightweight unibody construction gets 15MPG. WOW we have come a long way in 51 years have'nt we.
I think that our fuel has gotten so watered down with additives and cr&p that it's output is nowhere near what it used to be.

My truck makes 500hp and will get 20mpg. When new it wasn't too bad arround 16-17mpg on the road. It averages that now. The mods that helped milage the most were the timing the tst adds and a turbo with a less restrictive turbine housing. Big aggressive tires look great on our trucks but they rob power and fuel. I had to use restraint and went with 33" ProComp A/Ts. You have to check your milage with a gps to get a true figure. The O/D is a bit off. I have to stay under 65mph to get the best milage but when I'm on the interstate I run 75 and loose a couple mpg.

If I don't add the XZT soon I might hold out for your mileage box or a box that has the mileage setting on it with other settings for more HP.
