My house is on top of a hill. It is great leaving, I can just leave it in gear and coast down the hill to warm up my engine without sacrificing gas consumption. On the way home its a nightmare, I get about 13 mpgs over the 1.6 miles. It just murders my average mpgs, and today I lost .5 mpgs on a 225 mile tank
The hill is steep and curvy enough that I can't get out of 3rd gear without bogging way down, and the speed limit is 30 and then 40. I have tried going 30 the whole way, I have tried going 40 the whole way and my mpgs are stuck. Do i just need to accept defeat from gravity or is the a hypermiling technique that might net me even a little improvement.
This is a topographic map of my route from the bottom to top of the hill, courtesy of Google, it is about a 750 ft climb.
