Can you provide a good estimate of how gas mileage is affected by increasing one's speed five miles per hour?
Sources please.
I'm comparing 65 to 70 in an average sedan style car.

Just for quick reference, you need a benchmark. Some vehicles will get better gas mileage at a faster speed than others because the combination of aerodynamics, gearing of the transmission, and the optimal operating RPMs of the engine all meet at a slightly differing point.
What speeds are you comparing? 40 to 45, 45 to 50, 50 to 55, etc.
