...I did a regression analysis on your mpg values at 55, 60 and 65 and the 2nd-order polynomial equation came up with R-squared = 1.0 (perfect):
MPG = 0.0148*(MPH^2) - 2.0419*(MPH) + 112.81; RR = 1.0000
...do those numbers sound 'close' to what you're actually getting at those speeds?

I really haven't tested at those MPH's. But I would expect those results to hold true. I wish I was as good at math as you are.
