ok , not really.
I decided to drive the back mountain highways back home from my Uncle's funeral. I went through the center of Oregon,near some towns where he used to teach, back to Portland. Up this grade, around those 30mph corners, more grades more corners, snow,rain, more hills.
442mi. later and almost 8 hours and my tank was still not on empty,but close.Think I averaged 22, not bad for mountain driving, bench seat and a lot of shifting the manual transmission.
