I mentioned it in my intro post, but my clearest success story was on a trip that normally requires I stop for gas halfway through.

I made the entire trip on one tank, mostly due to sitting behind a big rig, 5 miles below the posted limit, for about 2 hours. Fortunately he was going the same way I was and never exited, and kept a steady pace.

It doubled my mileage on that trip, at least in theory. I don't have the exact numbers, but I remember being so surprised when we were back to our home city and hadn't needed to stop (it's a long trip we make frequently, and we know how often we normally stop).

I figure...those rigs are guzzling enough gas to power them along the highway...I might as well share some of that power in the form of a draft!
