My daily commute consists of 95% highway and with my current hours, I don't much traffic.
Usual rate of speed @ 75-80 mph gets me about 38 mpg during the winter (summertime is considerably better).
My average speed this past tankful was about 55-60 mpg. I got close to 41 mpg.
So a difference of approximately +2 mpg.
It was painful at first, but I got used to doing the speed limit, not on the far left lane of course.
But cars were still riding my ass, highbeaming me, giving me the finger as they passed, lol.
