I did a trip to Postfalls, ID from Lewiston, ID were I filled up at. I set my cruise for 55 MPH and never exceeded 55 MPH the whole trip even if the MAX speed limit was 75 MPH. I avoided interstates and stayed mostly to the older 2 lane highways. At a half tank a full I returned back from Postfalls, ID to Lewiston, ID... Here was my results...
21.7 MPG
17.6 Gallons of fuel consumed
17.3 Gallons of fuel remaining
385 Miles traveled
375 Miles of fuel remaining
9.4 hours of engine run time
9.3 hours of run time left
40 MPH average speed
$75.90 Total cost (at $4.299 a gallon)

But now to prove the point and show speed is the number one factor. I did a another trip from Riggins, ID to Weiser, ID for fire truck parts and since the Fire Dept was paying my fuel I did legal speed limit the entire trip. (65 MPH cruise set)
18.6 MPG
11.7 Gallons of fuel consumed
23.3 Gallons of fuel remaining
219 Miles traveled
433 Miles of fuel remaining
4.1 hours of engine run time
8.1 hours of run time left
53 MPH average speed
$51.60 Total cost (at $4.419 a gallon)

So pyro temp are directly related to MPG as I show here... These measurements are rough and can vary...
