Is the AC on or off?
That can be almost 5 MPG.

I am sure he was definately running the Air when he turned those
numbers because as you know all too well, Global Warming is so darn hot
you would risk heat exhaustion without it.

I disagree with the 5Mpg difference on any recent vehicle.

Try it on a nice hot day & see.
You probably don't have a rather precise MPG indicator
that can be set & reset as you drive (on level highway,
55 MPH IIRC, no head or tailwind).
I do.
Others, with larger vehicles, may do worse than I do ..... "almost".
