I do think you are correct that a steady speed would make differences more apparent. I just can't see the steady throttle making the numbers necessarily the same. If I set a steady fuel consumption rate (15.3 throttle) and achieve the same distance (18 miles) in less time, I should see higher MPG. But maybe the differences in fuel economy would not be as apparent with steady throttle as they would be if I held a steady speed. Does that make sense?

So a modification of my test method: on a shorter route (a 5.2 mile stretch of freeway I'll drive in each direction) the ground is flatter still and I'll be able to hold a steady speed. I'll do that. Thanks.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
