2006 5.4 f-250 CCLB mileage solo?
Just curious what kind of mileage your getting with the 5.4 solo? Just did a 442.3 mile trip and only averaged 13.32 running 75 mph. Runs good, new plugs and coils and air filter as well. A littl...

Running empty at 75mph, the engine type doesn't make a lot of difference. It's enough load that either is up into it's efficient power output without being overloaded.
Where you might see some difference is:
- At very low power output where the parasitic drag of a bigger engine will reduce MPG...but really, V8 to V10 isn't that much difference, so I wouldn't expect much. Probably too small to measure accurately.
- At very high output (pushing the V8 past it's tow rating), it could result in the V8 being outside it's efficient power output range while the V10 may stay within it's efficient range. There you might get a measurable difference.
