Thanks for all the info. The trouble I have with my commute is that it is not highway driving, nor is it city. I go through 9 traffic lights in a 14 mile commute during which my top speed using the accelerator is 47 miles per hour. I only exceed that when going downhill. The speed limit ranges between 35 and 45 miles per hour. Four of those traffic lights occur within about 1/3 mile of each other. The others occur between a mile and 8 miles apart. The trouble is that my morning commute has 1100 feet of total vertical gain, which kills my mileage. I somewhat make up for it on the afternoon trip home because it becomes mostly downhill.
My question stemming from all that info, is this; what exactly is the definition of highway driving? Is it interstate speeds of 55+ miles per hour, or would 8 miles on a rural 45mph route qualify? Does 4 miles of 35 miles per hour with no lights qualify as city or highway.
I p&g at every opportunity I can. I largely have my commute down to a science, but those stinking hills kill me.
I have become such a hyper mile geek that I relished a mild traffic jam on 128 outside Boston on my way to NH because I ultimately got almost 58 mpg on a tank when my last similar tank was barely 50 with a trip to NH.
As much as i want that kindergarten star, I want it legit, without fudging my city/highway ratio, but I have no clue as to how my daily commute on said route qualifies. Anyone familiar with 102 in North Kingstown and Exeter, RI?
