And this still applies. I know for a fact that I can speed up and slow down(60-25) as long as my speed doesn't exceed 60-65 I can get better mpg than at a constant speed of 75-80.

" How does a constant speed of 75-80mph result in better than epa ESTIMATES? Remember not guaranteed mpg at ANY speed. You realize parasite drag increases at an exponential rate, which means your heavier car with more power is going to burn even more gas as your speed increases. I am a pilot afterall, I have a pretty good understanding of physics. This concept is no different than in an airplane where I can use x power setting and go x speed, or y power and y speed (usually not much faster, 5%) but use 30-50% more fuel."
