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.. ...

Did both trucks decide direct gear in trans was used? If yes 6 or 10 speeds doesn’t matter for a highway cruising mpg test.

Wind and cooler denser air for red truck.

It would take some work but a test using 91 gas to allow the ecm to optimize timing vs the “minimum” recommended 87 would be interesting on a $/miles basis
