The Verdic is in, New Ford 7.3 V-8 Gas mpg not so Great

5.5 to 6.1 mpg while pulling a load, looks like the new 7.3 V-8 gets about the same mpg as the 6.8 V10.. Different motor same mpg, looks like the gas motorhomes are still stuck with bad mpg.. ...

It was silly to expect significant difference.

Go look at the guys with the 3.5 ecoboost...does great with an empty truck but load it and it does about the same as the V8.

Why? It takes fuel to develop power and when putting out a significant percentage of rated power, engines have been optimized for a long time...not a lot of improvement available.
