Hi Stevo12886:
___The Insight 5-speed at 70 + is about at its limit to achieve lean burn for any length of time. With a 15 - 20 miles per hour tail wind, certainly but on the highway at 70, I wouldn’t expect much time could be spent in its highest fuel economy mode … As for revs, hyper milers receive what they do when below 2,000. It might sound slow (it really is slow

) but that is where the Insight’s outrageous fuel economy is achieved.
___By the way, I added some commentary to your Used Insight post over at Insight Central a few minutes ago in case you don’t receive E-Mail notification.
___Good Luck
