...and it is absolutely true that speed makes a HUGE difference in the overall MPGS's.
I drove from LA to San Fran this past weekend (a 400 mile drive) and on the way up drove as I normally would, not using cruise control very often and averaging probably a little over 70 mph.
On the way back, I set the cruise control at 65 the entire way, only touching the gas pedal to pass the occasional semi.
Now, the drive north to San Fran is decidedly more uphill than the drive back to LA is, but the overall MPG difference was staggering.
LA to San Fran: approx. 44 mpg
San Fran to LA: approx. 51 mpg
That's huge!! And both trips took virtually the same amount of time, 6 and 1/2 hours.
